Radio, teletext decoders and - vertical blanking data interfaces are also provided. - - - - Radio Devices - - There are a wide variety of radio interfaces available for PC's, and these - are generally very simple to program. The biggest problem with supporting - such devices is normally extracting documentation from the vendor. - - - The radio interface supports a simple set of control ioctls standardised - across all radio and tv interfaces. It does not support read or write, which - are used for video streams. The reason radio cards do not allow you to read - the audio stream into an application is that without exception they provide - a connection on to a soundcard. Soundcards can be used to read the radio - data just fine. - - - Registering Radio Devices - - The Video4linux core provides an interface for registering devices. The - first step in writing our radio card driver is to register it. - - - - -static struct video_device my_radio -{ - "My radio", - VID_TYPE_TUNER, - radio_open. - radio_close, - NULL, /* no read */ - NULL, /* no write */ - NULL, /* no poll */ - radio_ioctl, - NULL, /* no special init function */ - NULL /* no private data */ -}; - - - - - This declares our video4linux device driver interface. The VID_TYPE_ value - defines what kind of an interface we are, and defines basic capabilities. - - - The only defined value relevant for a radio card is VID_TYPE_TUNER which - indicates that the device can be tuned. Clearly our radio is going to have some - way to change channel so it is tuneable. - - - We declare an open and close routine, but we do not need read or write, - which are used to read and write video data to or from the card itself. As - we have no read or write there is no poll function. - - - The private initialise function is run when the device is registered. In - this driver we've already done all the work needed. The final pointer is a - private data pointer that can be used by the device driver to attach and - retrieve private data structures. We set this field "priv" to NULL for - the moment. - - - Having the structure defined is all very well but we now need to register it - with the kernel. - - - - -static int io = 0x320; - -int __init myradio_init(struct video_init *v) -{ - if(!request_region(io, MY_IO_SIZE, "myradio")) - { - printk(KERN_ERR - "myradio: port 0x%03X is in use.\n", io); - return -EBUSY; - } - - if(video_device_register(&my_radio, VFL_TYPE_RADIO)==-1) { - release_region(io, MY_IO_SIZE); - return -EINVAL; - } - return 0; -} - - - - The first stage of the initialisation, as is normally the case, is to check - that the I/O space we are about to fiddle with doesn't belong to some other - driver. If it is we leave well alone. If the user gives the address of the - wrong device then we will spot this. These policies will generally avoid - crashing the machine. - - - Now we ask the Video4Linux layer to register the device for us. We hand it - our carefully designed video_device structure and also tell it which group - of devices we want it registered with. In this case VFL_TYPE_RADIO. - - - The types available are - - Device Types - - - - VFL_TYPE_RADIO/dev/radio{n} - - Radio devices are assigned in this block. As with all of these - selections the actual number assignment is done by the video layer - accordijng to what is free. - - VFL_TYPE_GRABBER/dev/video{n} - Video capture devices and also -- counter-intuitively for the name -- - hardware video playback devices such as MPEG2 cards. - - VFL_TYPE_VBI/dev/vbi{n} - The VBI devices capture the hidden lines on a television picture - that carry further information like closed caption data, teletext - (primarily in Europe) and now Intercast and the ATVEC internet - television encodings. - - VFL_TYPE_VTX/dev/vtx[n} - VTX is 'Videotext' also known as 'Teletext'. This is a system for - sending numbered, 40x25, mostly textual page images over the hidden - lines. Unlike the /dev/vbi interfaces, this is for 'smart' decoder - chips. (The use of the word smart here has to be taken in context, - the smartest teletext chips are fairly dumb pieces of technology). - - - - -
- - We are most definitely a radio. - - - Finally we allocate our I/O space so that nobody treads on us and return 0 - to signify general happiness with the state of the universe. - - - - Opening And Closing The Radio - - - The functions we declared in our video_device are mostly very simple. - Firstly we can drop in what is basically standard code for open and close. - - - - -static int users = 0; - -static int radio_open(struct video_device *dev, int flags) -{ - if(users) - return -EBUSY; - users++; - return 0; -} - - - - At open time we need to do nothing but check if someone else is also using - the radio card. If nobody is using it we make a note that we are using it, - then we ensure that nobody unloads our driver on us. - - - - -static int radio_close(struct video_device *dev) -{ - users--; -} - - - - At close time we simply need to reduce the user count and allow the module - to become unloadable. - - - If you are sharp you will have noticed neither the open nor the close - routines attempt to reset or change the radio settings. This is intentional. - It allows an application to set up the radio and exit. It avoids a user - having to leave an application running all the time just to listen to the - radio. - - - - The Ioctl Interface - - This leaves the ioctl routine, without which the driver will not be - terribly useful to anyone. - - - - -static int radio_ioctl(struct video_device *dev, unsigned int cmd, void *arg) -{ - switch(cmd) - { - case VIDIOCGCAP: - { - struct video_capability v; - v.type = VID_TYPE_TUNER; - v.channels = 1; - v.audios = 1; - v.maxwidth = 0; - v.minwidth = 0; - v.maxheight = 0; - v.minheight = 0; - strcpy(v.name, "My Radio"); - if(copy_to_user(arg, &v, sizeof(v))) - return -EFAULT; - return 0; - } - - - - VIDIOCGCAP is the first ioctl all video4linux devices must support. It - allows the applications to find out what sort of a card they have found and - to figure out what they want to do about it. The fields in the structure are - - struct video_capability fields - - - - nameThe device text name. This is intended for the user. - - channelsThe number of different channels you can tune on - this card. It could even by zero for a card that has - no tuning capability. For our simple FM radio it is 1. - An AM/FM radio would report 2. - - audiosThe number of audio inputs on this device. For our - radio there is only one audio input. - - minwidth,minheightThe smallest size the card is capable of capturing - images in. We set these to zero. Radios do not - capture pictures - - maxwidth,maxheightThe largest image size the card is capable of - capturing. For our radio we report 0. - - - typeThis reports the capabilities of the device, and - matches the field we filled in in the struct - video_device when registering. - - - -
- - Having filled in the fields, we use copy_to_user to copy the structure into - the users buffer. If the copy fails we return an EFAULT to the application - so that it knows it tried to feed us garbage. - - - The next pair of ioctl operations select which tuner is to be used and let - the application find the tuner properties. We have only a single FM band - tuner in our example device. - - - - - case VIDIOCGTUNER: - { - struct video_tuner v; - if(copy_from_user(&v, arg, sizeof(v))!=0) - return -EFAULT; - if(v.tuner) - return -EINVAL; - v.rangelow=(87*16000); - v.rangehigh=(108*16000); - v.flags = VIDEO_TUNER_LOW; - v.mode = VIDEO_MODE_AUTO; - v.signal = 0xFFFF; - strcpy(v.name, "FM"); - if(copy_to_user(&v, arg, sizeof(v))!=0) - return -EFAULT; - return 0; - } - - - - The VIDIOCGTUNER ioctl allows applications to query a tuner. The application - sets the tuner field to the tuner number it wishes to query. The query does - not change the tuner that is being used, it merely enquires about the tuner - in question. - - - We have exactly one tuner so after copying the user buffer to our temporary - structure we complain if they asked for a tuner other than tuner 0. - - - The video_tuner structure has the following fields - - struct video_tuner fields - - - - int tunerThe number of the tuner in question - - char name[32]A text description of this tuner. "FM" will do fine. - This is intended for the application. - - u32 flags - Tuner capability flags - - - u16 modeThe current reception mode - - - u16 signalThe signal strength scaled between 0 and 65535. If - a device cannot tell the signal strength it should - report 65535. Many simple cards contain only a - signal/no signal bit. Such cards will report either - 0 or 65535. - - - u32 rangelow, rangehigh - The range of frequencies supported by the radio - or TV. It is scaled according to the VIDEO_TUNER_LOW - flag. - - - - -

- - The settings for the radio card are thus fairly simple. We report that we - are a tuner called "FM" for FM radio. In order to get the best tuning - resolution we report VIDEO_TUNER_LOW and select tuning to 1/16th of KHz. Its - unlikely our card can do that resolution but it is a fair bet the card can - do better than 1/16th of a MHz. VIDEO_TUNER_LOW is appropriate to almost all - radio usage. - - - We report that the tuner automatically handles deciding what format it is - receiving - true enough as it only handles FM radio. Our example card is - also incapable of detecting stereo or signal strengths so it reports a - strength of 0xFFFF (maximum) and no stereo detected. - - - To finish off we set the range that can be tuned to be 87-108Mhz, the normal - FM broadcast radio range. It is important to find out what the card is - actually capable of tuning. It is easy enough to simply use the FM broadcast - range. Unfortunately if you do this you will discover the FM broadcast - ranges in the USA, Europe and Japan are all subtly different and some users - cannot receive all the stations they wish. - - - The application also needs to be able to set the tuner it wishes to use. In - our case, with a single tuner this is rather simple to arrange. - - - - case VIDIOCSTUNER: - { - struct video_tuner v; - if(copy_from_user(&v, arg, sizeof(v))) - return -EFAULT; - if(v.tuner != 0) - return -EINVAL; - return 0; - } - - - - We copy the user supplied structure into kernel memory so we can examine it. - If the user has selected a tuner other than zero we reject the request. If - they wanted tuner 0 then, surprisingly enough, that is the current tuner already. - - - The next two ioctls we need to provide are to get and set the frequency of - the radio. These both use an unsigned long argument which is the frequency. - The scale of the frequency depends on the VIDEO_TUNER_LOW flag as I - mentioned earlier on. Since we have VIDEO_TUNER_LOW set this will be in - 1/16ths of a KHz. - - - -static unsigned long current_freq; - - - - case VIDIOCGFREQ: - if(copy_to_user(arg, &current_freq, - sizeof(unsigned long)) - return -EFAULT; - return 0; - - - - Querying the frequency in our case is relatively simple. Our radio card is - too dumb to let us query the signal strength so we remember our setting if - we know it. All we have to do is copy it to the user. - - - - - case VIDIOCSFREQ: - { - u32 freq; - if(copy_from_user(arg, &freq, - sizeof(unsigned long))!=0) - return -EFAULT; - if(hardware_set_freq(freq)<0) - return -EINVAL; - current_freq = freq; - return 0; - } - - - - Setting the frequency is a little more complex. We begin by copying the - desired frequency into kernel space. Next we call a hardware specific routine - to set the radio up. This might be as simple as some scaling and a few - writes to an I/O port. For most radio cards it turns out a good deal more - complicated and may involve programming things like a phase locked loop on - the card. This is what documentation is for. - - - The final set of operations we need to provide for our radio are the - volume controls. Not all radio cards can even do volume control. After all - there is a perfectly good volume control on the sound card. We will assume - our radio card has a simple 4 step volume control. - - - There are two ioctls with audio we need to support - - - -static int current_volume=0; - - case VIDIOCGAUDIO: - { - struct video_audio v; - if(copy_from_user(&v, arg, sizeof(v))) - return -EFAULT; - if(v.audio != 0) - return -EINVAL; - v.volume = 16384*current_volume; - v.step = 16384; - strcpy(v.name, "Radio"); - v.mode = VIDEO_SOUND_MONO; - v.balance = 0; - v.base = 0; - v.treble = 0; - - if(copy_to_user(arg. &v, sizeof(v))) - return -EFAULT; - return 0; - } - - - - Much like the tuner we start by copying the user structure into kernel - space. Again we check if the user has asked for a valid audio input. We have - only input 0 and we punt if they ask for another input. - - - Then we fill in the video_audio structure. This has the following format - - struct video_audio fields - - - - audioThe input the user wishes to query - - volumeThe volume setting on a scale of 0-65535 - - baseThe base level on a scale of 0-65535 - - trebleThe treble level on a scale of 0-65535 - - flagsThe features this audio device supports - - - nameA text name to display to the user. We picked - "Radio" as it explains things quite nicely. - - modeThe current reception mode for the audio - - We report MONO because our card is too stupid to know if it is in - mono or stereo. - - - balanceThe stereo balance on a scale of 0-65535, 32768 is - middle. - - stepThe step by which the volume control jumps. This is - used to help make it easy for applications to set - slider behaviour. - - - -
- - struct video_audio flags - - - - VIDEO_AUDIO_MUTEThe audio is currently muted. We - could fake this in our driver but we - choose not to bother. - - VIDEO_AUDIO_MUTABLEThe input has a mute option - - VIDEO_AUDIO_TREBLEThe input has a treble control - - VIDEO_AUDIO_BASSThe input has a base control - - - -

- - Having filled in the structure we copy it back to user space. - - - The VIDIOCSAUDIO ioctl allows the user to set the audio parameters in the - video_audio structure. The driver does its best to honour the request. - - - - case VIDIOCSAUDIO: - { - struct video_audio v; - if(copy_from_user(&v, arg, sizeof(v))) - return -EFAULT; - if(v.audio) - return -EINVAL; - current_volume = v/16384; - hardware_set_volume(current_volume); - return 0; - } - - - - In our case there is very little that the user can set. The volume is - basically the limit. Note that we could pretend to have a mute feature - by rewriting this to - - - - case VIDIOCSAUDIO: - { - struct video_audio v; - if(copy_from_user(&v, arg, sizeof(v))) - return -EFAULT; - if(v.audio) - return -EINVAL; - current_volume = v/16384; - if(v.flags&VIDEO_AUDIO_MUTE) - hardware_set_volume(0); - else - hardware_set_volume(current_volume); - current_muted = v.flags & - VIDEO_AUDIO_MUTE; - return 0; - } - - - - This with the corresponding changes to the VIDIOCGAUDIO code to report the - state of the mute flag we save and to report the card has a mute function, - will allow applications to use a mute facility with this card. It is - questionable whether this is a good idea however. User applications can already - fake this themselves and kernel space is precious. - - - We now have a working radio ioctl handler. So we just wrap up the function - - - - - } - return -ENOIOCTLCMD; -} - - - - and pass the Video4Linux layer back an error so that it knows we did not - understand the request we got passed. - - - - Module Wrapper - - Finally we add in the usual module wrapping and the driver is done. - - - -#ifndef MODULE - -static int io = 0x300; - -#else - -static int io = -1; - -#endif - -MODULE_AUTHOR("Alan Cox"); -MODULE_DESCRIPTION("A driver for an imaginary radio card."); -module_param(io, int, 0444); -MODULE_PARM_DESC(io, "I/O address of the card."); - -static int __init init(void) -{ - if(io==-1) - { - printk(KERN_ERR - "You must set an I/O address with io=0x???\n"); - return -EINVAL; - } - return myradio_init(NULL); -} - -static void __exit cleanup(void) -{ - video_unregister_device(&my_radio); - release_region(io, MY_IO_SIZE); -} - -module_init(init); -module_exit(cleanup); - - - - In this example we set the IO base by default if the driver is compiled into - the kernel: you can still set it using "my_radio.irq" if this file is called my_radio.c. For the module we require the - user sets the parameter. We set io to a nonsense port (-1) so that we can - tell if the user supplied an io parameter or not. - - - We use MODULE_ defines to give an author for the card driver and a - description. We also use them to declare that io is an integer and it is the - address of the card, and can be read by anyone from sysfs. - - - The clean-up routine unregisters the video_device we registered, and frees - up the I/O space. Note that the unregister takes the actual video_device - structure as its argument. Unlike the file operations structure which can be - shared by all instances of a device a video_device structure as an actual - instance of the device. If you are registering multiple radio devices you - need to fill in one structure per device (most likely by setting up a - template and copying it to each of the actual device structures). - - - - - Video Capture Devices - - Video Capture Device Types - - The video capture devices share the same interfaces as radio devices. In - order to explain the video capture interface I will use the example of a - camera that has no tuners or audio input. This keeps the example relatively - clean. To get both combine the two driver examples. - - - Video capture devices divide into four categories. A little technology - backgrounder. Full motion video even at television resolution (which is - actually fairly low) is pretty resource-intensive. You are continually - passing megabytes of data every second from the capture card to the display. - several alternative approaches have emerged because copying this through the - processor and the user program is a particularly bad idea . - - - The first is to add the television image onto the video output directly. - This is also how some 3D cards work. These basic cards can generally drop the - video into any chosen rectangle of the display. Cards like this, which - include most mpeg1 cards that used the feature connector, aren't very - friendly in a windowing environment. They don't understand windows or - clipping. The video window is always on the top of the display. - - - Chroma keying is a technique used by cards to get around this. It is an old - television mixing trick where you mark all the areas you wish to replace - with a single clear colour that isn't used in the image - TV people use an - incredibly bright blue while computing people often use a particularly - virulent purple. Bright blue occurs on the desktop. Anyone with virulent - purple windows has another problem besides their TV overlay. - - - The third approach is to copy the data from the capture card to the video - card, but to do it directly across the PCI bus. This relieves the processor - from doing the work but does require some smartness on the part of the video - capture chip, as well as a suitable video card. Programming this kind of - card and more so debugging it can be extremely tricky. There are some quite - complicated interactions with the display and you may also have to cope with - various chipset bugs that show up when PCI cards start talking to each - other. - - - To keep our example fairly simple we will assume a card that supports - overlaying a flat rectangular image onto the frame buffer output, and which - can also capture stuff into processor memory. - - - - Registering Video Capture Devices - - This time we need to add more functions for our camera device. - - -static struct video_device my_camera -{ - "My Camera", - VID_TYPE_OVERLAY|VID_TYPE_SCALES|\ - VID_TYPE_CAPTURE|VID_TYPE_CHROMAKEY, - camera_open. - camera_close, - camera_read, /* no read */ - NULL, /* no write */ - camera_poll, /* no poll */ - camera_ioctl, - NULL, /* no special init function */ - NULL /* no private data */ -}; - - - We need a read() function which is used for capturing data from - the card, and we need a poll function so that a driver can wait for the next - frame to be captured. - - - We use the extra video capability flags that did not apply to the - radio interface. The video related flags are - - Capture Capabilities - - - -VID_TYPE_CAPTUREWe support image capture - -VID_TYPE_TELETEXTA teletext capture device (vbi{n]) - -VID_TYPE_OVERLAYThe image can be directly overlaid onto the - frame buffer - -VID_TYPE_CHROMAKEYChromakey can be used to select which parts - of the image to display - -VID_TYPE_CLIPPINGIt is possible to give the board a list of - rectangles to draw around. - -VID_TYPE_FRAMERAMThe video capture goes into the video memory - and actually changes it. Applications need - to know this so they can clean up after the - card - -VID_TYPE_SCALESThe image can be scaled to various sizes, - rather than being a single fixed size. - -VID_TYPE_MONOCHROMEThe capture will be monochrome. This isn't a - complete answer to the question since a mono - camera on a colour capture card will still - produce mono output. - -VID_TYPE_SUBCAPTUREThe card allows only part of its field of - view to be captured. This enables - applications to avoid copying all of a large - image into memory when only some section is - relevant. - - - -
- - We set VID_TYPE_CAPTURE so that we are seen as a capture card, - VID_TYPE_CHROMAKEY so the application knows it is time to draw in virulent - purple, and VID_TYPE_SCALES because we can be resized. - - - Our setup is fairly similar. This time we also want an interrupt line - for the 'frame captured' signal. Not all cards have this so some of them - cannot handle poll(). - - - - -static int io = 0x320; -static int irq = 11; - -int __init mycamera_init(struct video_init *v) -{ - if(!request_region(io, MY_IO_SIZE, "mycamera")) - { - printk(KERN_ERR - "mycamera: port 0x%03X is in use.\n", io); - return -EBUSY; - } - - if(video_device_register(&my_camera, - VFL_TYPE_GRABBER)==-1) { - release_region(io, MY_IO_SIZE); - return -EINVAL; - } - return 0; -} - - - - This is little changed from the needs of the radio card. We specify - VFL_TYPE_GRABBER this time as we want to be allocated a /dev/video name. - - - - Opening And Closing The Capture Device - - - -static int users = 0; - -static int camera_open(struct video_device *dev, int flags) -{ - if(users) - return -EBUSY; - if(request_irq(irq, camera_irq, 0, "camera", dev)<0) - return -EBUSY; - users++; - return 0; -} - - -static int camera_close(struct video_device *dev) -{ - users--; - free_irq(irq, dev); -} - - - The open and close routines are also quite similar. The only real change is - that we now request an interrupt for the camera device interrupt line. If we - cannot get the interrupt we report EBUSY to the application and give up. - - - - Interrupt Handling - - Our example handler is for an ISA bus device. If it was PCI you would be - able to share the interrupt and would have set IRQF_SHARED to indicate a - shared IRQ. We pass the device pointer as the interrupt routine argument. We - don't need to since we only support one card but doing this will make it - easier to upgrade the driver for multiple devices in the future. - - - Our interrupt routine needs to do little if we assume the card can simply - queue one frame to be read after it captures it. - - - - -static struct wait_queue *capture_wait; -static int capture_ready = 0; - -static void camera_irq(int irq, void *dev_id, - struct pt_regs *regs) -{ - capture_ready=1; - wake_up_interruptible(&capture_wait); -} - - - The interrupt handler is nice and simple for this card as we are assuming - the card is buffering the frame for us. This means we have little to do but - wake up anybody interested. We also set a capture_ready flag, as we may - capture a frame before an application needs it. In this case we need to know - that a frame is ready. If we had to collect the frame on the interrupt life - would be more complex. - - - The two new routines we need to supply are camera_read which returns a - frame, and camera_poll which waits for a frame to become ready. - - - - -static int camera_poll(struct video_device *dev, - struct file *file, struct poll_table *wait) -{ - poll_wait(file, &capture_wait, wait); - if(capture_read) - return POLLIN|POLLRDNORM; - return 0; -} - - - - Our wait queue for polling is the capture_wait queue. This will cause the - task to be woken up by our camera_irq routine. We check capture_read to see - if there is an image present and if so report that it is readable. - - - - Reading The Video Image - - - -static long camera_read(struct video_device *dev, char *buf, - unsigned long count) -{ - struct wait_queue wait = { current, NULL }; - u8 *ptr; - int len; - int i; - - add_wait_queue(&capture_wait, &wait); - - while(!capture_ready) - { - if(file->flags&O_NDELAY) - { - remove_wait_queue(&capture_wait, &wait); - current->state = TASK_RUNNING; - return -EWOULDBLOCK; - } - if(signal_pending(current)) - { - remove_wait_queue(&capture_wait, &wait); - current->state = TASK_RUNNING; - return -ERESTARTSYS; - } - schedule(); - current->state = TASK_INTERRUPTIBLE; - } - remove_wait_queue(&capture_wait, &wait); - current->state = TASK_RUNNING; - - - - The first thing we have to do is to ensure that the application waits until - the next frame is ready. The code here is almost identical to the mouse code - we used earlier in this chapter. It is one of the common building blocks of - Linux device driver code and probably one which you will find occurs in any - drivers you write. - - - We wait for a frame to be ready, or for a signal to interrupt our waiting. If a - signal occurs we need to return from the system call so that the signal can - be sent to the application itself. We also check to see if the user actually - wanted to avoid waiting - ie if they are using non-blocking I/O and have other things - to get on with. - - - Next we copy the data from the card to the user application. This is rarely - as easy as our example makes out. We will add capture_w, and capture_h here - to hold the width and height of the captured image. We assume the card only - supports 24bit RGB for now. - - - - - - capture_ready = 0; - - ptr=(u8 *)buf; - len = capture_w * 3 * capture_h; /* 24bit RGB */ - - if(len>count) - len=count; /* Doesn't all fit */ - - for(i=0; i<len; i++) - { - put_user(inb(io+IMAGE_DATA), ptr); - ptr++; - } - - hardware_restart_capture(); - - return i; -} - - - - For a real hardware device you would try to avoid the loop with put_user(). - Each call to put_user() has a time overhead checking whether the accesses to user - space are allowed. It would be better to read a line into a temporary buffer - then copy this to user space in one go. - - - Having captured the image and put it into user space we can kick the card to - get the next frame acquired. - - - - Video Ioctl Handling - - As with the radio driver the major control interface is via the ioctl() - function. Video capture devices support the same tuner calls as a radio - device and also support additional calls to control how the video functions - are handled. In this simple example the card has no tuners to avoid making - the code complex. - - - - - -static int camera_ioctl(struct video_device *dev, unsigned int cmd, void *arg) -{ - switch(cmd) - { - case VIDIOCGCAP: - { - struct video_capability v; - v.type = VID_TYPE_CAPTURE|\ - VID_TYPE_CHROMAKEY|\ - VID_TYPE_SCALES|\ - VID_TYPE_OVERLAY; - v.channels = 1; - v.audios = 0; - v.maxwidth = 640; - v.minwidth = 16; - v.maxheight = 480; - v.minheight = 16; - strcpy(v.name, "My Camera"); - if(copy_to_user(arg, &v, sizeof(v))) - return -EFAULT; - return 0; - } - - - - - The first ioctl we must support and which all video capture and radio - devices are required to support is VIDIOCGCAP. This behaves exactly the same - as with a radio device. This time, however, we report the extra capabilities - we outlined earlier on when defining our video_dev structure. - - - We now set the video flags saying that we support overlay, capture, - scaling and chromakey. We also report size limits - our smallest image is - 16x16 pixels, our largest is 640x480. - - - To keep things simple we report no audio and no tuning capabilities at all. - - - - case VIDIOCGCHAN: - { - struct video_channel v; - if(copy_from_user(&v, arg, sizeof(v))) - return -EFAULT; - if(v.channel != 0) - return -EINVAL; - v.flags = 0; - v.tuners = 0; - v.type = VIDEO_TYPE_CAMERA; - v.norm = VIDEO_MODE_AUTO; - strcpy(v.name, "Camera Input");break; - if(copy_to_user(&v, arg, sizeof(v))) - return -EFAULT; - return 0; - } - - - - - This follows what is very much the standard way an ioctl handler looks - in Linux. We copy the data into a kernel space variable and we check that the - request is valid (in this case that the input is 0). Finally we copy the - camera info back to the user. - - - The VIDIOCGCHAN ioctl allows a user to ask about video channels (that is - inputs to the video card). Our example card has a single camera input. The - fields in the structure are - - struct video_channel fields - - - - - channelThe channel number we are selecting - - nameThe name for this channel. This is intended - to describe the port to the user. - Appropriate names are therefore things like - "Camera" "SCART input" - - flagsChannel properties - - typeInput type - - normThe current television encoding being used - if relevant for this channel. - - - - -
- struct video_channel flags - - - - VIDEO_VC_TUNERChannel has a tuner. - - VIDEO_VC_AUDIOChannel has audio. - - - -
- struct video_channel types - - - - VIDEO_TYPE_TVTelevision input. - - VIDEO_TYPE_CAMERAFixed camera input. - - 0Type is unknown. - - - -
- struct video_channel norms - - - - VIDEO_MODE_PALPAL encoded Television - - VIDEO_MODE_NTSCNTSC (US) encoded Television - - VIDEO_MODE_SECAMSECAM (French) Television - - VIDEO_MODE_AUTOAutomatic switching, or format does not - matter - - - -
- - The corresponding VIDIOCSCHAN ioctl allows a user to change channel and to - request the norm is changed - for example to switch between a PAL or an NTSC - format camera. - - - - - case VIDIOCSCHAN: - { - struct video_channel v; - if(copy_from_user(&v, arg, sizeof(v))) - return -EFAULT; - if(v.channel != 0) - return -EINVAL; - if(v.norm != VIDEO_MODE_AUTO) - return -EINVAL; - return 0; - } - - - - - The implementation of this call in our driver is remarkably easy. Because we - are assuming fixed format hardware we need only check that the user has not - tried to change anything. - - - The user also needs to be able to configure and adjust the picture they are - seeing. This is much like adjusting a television set. A user application - also needs to know the palette being used so that it knows how to display - the image that has been captured. The VIDIOCGPICT and VIDIOCSPICT ioctl - calls provide this information. - - - - - case VIDIOCGPICT - { - struct video_picture v; - v.brightness = hardware_brightness(); - v.hue = hardware_hue(); - v.colour = hardware_saturation(); - v.contrast = hardware_brightness(); - /* Not settable */ - v.whiteness = 32768; - v.depth = 24; /* 24bit */ - v.palette = VIDEO_PALETTE_RGB24; - if(copy_to_user(&v, arg, - sizeof(v))) - return -EFAULT; - return 0; - } - - - - - The brightness, hue, color, and contrast provide the picture controls that - are akin to a conventional television. Whiteness provides additional - control for greyscale images. All of these values are scaled between 0-65535 - and have 32768 as the mid point setting. The scaling means that applications - do not have to worry about the capability range of the hardware but can let - it make a best effort attempt. - - - Our depth is 24, as this is in bits. We will be returning RGB24 format. This - has one byte of red, then one of green, then one of blue. This then repeats - for every other pixel in the image. The other common formats the interface - defines are - - Framebuffer Encodings - - - - GREYLinear greyscale. This is for simple cameras and the - like - - RGB565The top 5 bits hold 32 red levels, the next six bits - hold green and the low 5 bits hold blue. - - RGB555The top bit is clear. The red green and blue levels - each occupy five bits. - - - -
- - Additional modes are support for YUV capture formats. These are common for - TV and video conferencing applications. - - - The VIDIOCSPICT ioctl allows a user to set some of the picture parameters. - Exactly which ones are supported depends heavily on the card itself. It is - possible to support many modes and effects in software. In general doing - this in the kernel is a bad idea. Video capture is a performance-sensitive - application and the programs can often do better if they aren't being - 'helped' by an overkeen driver writer. Thus for our device we will report - RGB24 only and refuse to allow a change. - - - - - case VIDIOCSPICT: - { - struct video_picture v; - if(copy_from_user(&v, arg, sizeof(v))) - return -EFAULT; - if(v.depth!=24 || - v.palette != VIDEO_PALETTE_RGB24) - return -EINVAL; - set_hardware_brightness(v.brightness); - set_hardware_hue(v.hue); - set_hardware_saturation(v.colour); - set_hardware_brightness(v.contrast); - return 0; - } - - - - - We check the user has not tried to change the palette or the depth. We do - not want to carry out some of the changes and then return an error. This may - confuse the application which will be assuming no change occurred. - - - In much the same way as you need to be able to set the picture controls to - get the right capture images, many cards need to know what they are - displaying onto when generating overlay output. In some cases getting this - wrong even makes a nasty mess or may crash the computer. For that reason - the VIDIOCSBUF ioctl used to set up the frame buffer information may well - only be usable by root. - - - We will assume our card is one of the old ISA devices with feature connector - and only supports a couple of standard video modes. Very common for older - cards although the PCI devices are way smarter than this. - - - - -static struct video_buffer capture_fb; - - case VIDIOCGFBUF: - { - if(copy_to_user(arg, &capture_fb, - sizeof(capture_fb))) - return -EFAULT; - return 0; - - } - - - - - We keep the frame buffer information in the format the ioctl uses. This - makes it nice and easy to work with in the ioctl calls. - - - - case VIDIOCSFBUF: - { - struct video_buffer v; - - if(!capable(CAP_SYS_ADMIN)) - return -EPERM; - - if(copy_from_user(&v, arg, sizeof(v))) - return -EFAULT; - if(v.width!=320 && v.width!=640) - return -EINVAL; - if(v.height!=200 && v.height!=240 - && v.height!=400 - && v.height !=480) - return -EINVAL; - memcpy(&capture_fb, &v, sizeof(v)); - hardware_set_fb(&v); - return 0; - } - - - - - - The capable() function checks a user has the required capability. The Linux - operating system has a set of about 30 capabilities indicating privileged - access to services. The default set up gives the superuser (uid 0) all of - them and nobody else has any. - - - We check that the user has the SYS_ADMIN capability, that is they are - allowed to operate as the machine administrator. We don't want anyone but - the administrator making a mess of the display. - - - Next we check for standard PC video modes (320 or 640 wide with either - EGA or VGA depths). If the mode is not a standard video mode we reject it as - not supported by our card. If the mode is acceptable we save it so that - VIDIOCFBUF will give the right answer next time it is called. The - hardware_set_fb() function is some undescribed card specific function to - program the card for the desired mode. - - - Before the driver can display an overlay window it needs to know where the - window should be placed, and also how large it should be. If the card - supports clipping it needs to know which rectangles to omit from the - display. The video_window structure is used to describe the way the image - should be displayed. - - struct video_window fields - - - - widthThe width in pixels of the desired image. The card - may use a smaller size if this size is not available - - heightThe height of the image. The card may use a smaller - size if this size is not available. - - x The X position of the top left of the window. This - is in pixels relative to the left hand edge of the - picture. Not all cards can display images aligned on - any pixel boundary. If the position is unsuitable - the card adjusts the image right and reduces the - width. - - y The Y position of the top left of the window. This - is counted in pixels relative to the top edge of the - picture. As with the width if the card cannot - display starting on this line it will adjust the - values. - - chromakeyThe colour (expressed in RGB32 format) for the - chromakey colour if chroma keying is being used. - - clipsAn array of rectangles that must not be drawn - over. - - clipcountThe number of clips in this array. - - - -
- - Each clip is a struct video_clip which has the following fields - - video_clip fields - - - - x, yCo-ordinates relative to the display - - width, heightWidth and height in pixels - - nextA spare field for the application to use - - - -
- - The driver is required to ensure it always draws in the area requested or a smaller area, and that it never draws in any of the areas that are clipped. - This may well mean it has to leave alone. small areas the application wished to be - drawn. - - - Our example card uses chromakey so does not have to address most of the - clipping. We will add a video_window structure to our global variables to - remember our parameters, as we did with the frame buffer. - - - - - case VIDIOCGWIN: - { - if(copy_to_user(arg, &capture_win, - sizeof(capture_win))) - return -EFAULT; - return 0; - } - - - case VIDIOCSWIN: - { - struct video_window v; - if(copy_from_user(&v, arg, sizeof(v))) - return -EFAULT; - if(v.width > 640 || v.height > 480) - return -EINVAL; - if(v.width < 16 || v.height < 16) - return -EINVAL; - hardware_set_key(v.chromakey); - hardware_set_window(v); - memcpy(&capture_win, &v, sizeof(v)); - capture_w = v.width; - capture_h = v.height; - return 0; - } - - - - - Because we are using Chromakey our setup is fairly simple. Mostly we have to - check the values are sane and load them into the capture card. - - - With all the setup done we can now turn on the actual capture/overlay.

Working with reviewers is a crucial part of the +development process; this section offers a number of tips on how to avoid +problems at this important stage. Developers are cautioned against +assuming that the job is done when a patch is merged into the mainline. + +Section 7 introduces a couple of "advanced" topics: managing patches with +git and reviewing patches posted by others. + +Section 8 concludes the document with pointers to sources for more +information on kernel development. + + +1.2: WHAT THIS DOCUMENT IS ABOUT + +The Linux kernel, at over 6 million lines of code and well over 1000 active +contributors, is one of the largest and most active free software projects +in existence. Since its humble beginning in 1991, this kernel has evolved +into a best-of-breed operating system component which runs on pocket-sized +digital music players, desktop PCs, the largest supercomputers in +existence, and all types of systems in between. It is a robust, efficient, +and scalable solution for almost any situation. + +With the growth of Linux has come an increase in the number of developers +(and companies) wishing to participate in its development. Hardware +vendors want to ensure that Linux supports their products well, making +those products attractive to Linux users. Embedded systems vendors, who +use Linux as a component in an integrated product, want Linux to be as +capable and well-suited to the task at hand as possible. Distributors and +other software vendors who base their products on Linux have a clear +interest in the capabilities, performance, and reliability of the Linux +kernel. And end users, too, will often wish to change Linux to make it +better suit their needs. + +One of the most compelling features of Linux is that it is accessible to +these developers; anybody with the requisite skills can improve Linux and +influence the direction of its development. Proprietary products cannot +offer this kind of openness, which is a characteristic of the free software +process. But, if anything, the kernel is even more open than most other +free software projects. A typical three-month kernel development cycle can +involve over 1000 developers working for more than 100 different companies +(or for no company at all). + +Working with the kernel development community is not especially hard. But, +that notwithstanding, many potential contributors have experienced +difficulties when trying to do kernel work. The kernel community has +evolved its own distinct ways of operating which allow it to function +smoothly (and produce a high-quality product) in an environment where +thousands of lines of code are being changed every day. So it is not +surprising that Linux kernel development process differs greatly from +proprietary development methods. + +The kernel's development process may come across as strange and +intimidating to new developers, but there are good reasons and solid +experience behind it. A developer who does not understand the kernel +community's ways (or, worse, who tries to flout or circumvent them) will +have a frustrating experience in store. The development community, while +being helpful to those who are trying to learn, has little time for those +who will not listen or who do not care about the development process. + +It is hoped that those who read this document will be able to avoid that +frustrating experience. There is a lot of material here, but the effort +involved in reading it will be repaid in short order. The development +community is always in need of developers who will help to make the kernel +better; the following text should help you - or those who work for you - +join our community. + + +1.3: CREDITS + +This document was written by Jonathan Corbet, corbet@lwn.net. It has been +improved by comments from Johannes Berg, James Berry, Alex Chiang, Roland +Dreier, Randy Dunlap, Jake Edge, Jiri Kosina, Matt Mackall, Arthur Marsh, +Amanda McPherson, Andrew Morton, Andrew Price, Tsugikazu Shibata, and +Jochen Voß. + +This work was supported by the Linux Foundation; thanks especially to +Amanda McPherson, who saw the value of this effort and made it all happen. + + +1.4: THE IMPORTANCE OF GETTING CODE INTO THE MAINLINE + +Some companies and developers occasionally wonder why they should bother +learning how to work with the kernel community and get their code into the +mainline kernel (the "mainline" being the kernel maintained by Linus +Torvalds and used as a base by Linux distributors). In the short term, +contributing code can look like an avoidable expense; it seems easier to +just keep the code separate and support users directly. The truth of the +matter is that keeping code separate ("out of tree") is a false economy. + +As a way of illustrating the costs of out-of-tree code, here are a few +relevant aspects of the kernel development process; most of these will be +discussed in greater detail later in this document. Consider: + +- Code which has been merged into the mainline kernel is available to all + Linux users. It will automatically be present on all distributions which + enable it. There is no need for driver disks, downloads, or the hassles + of supporting multiple versions of multiple distributions; it all just + works, for the developer and for the user. Incorporation into the + mainline solves a large number of distribution and support problems. + +- While kernel developers strive to maintain a stable interface to user + space, the internal kernel API is in constant flux. The lack of a stable + internal interface is a deliberate design decision; it allows fundamental + improvements to be made at any time and results in higher-quality code. + But one result of that policy is that any out-of-tree code requires + constant upkeep if it is to work with new kernels. Maintaining + out-of-tree code requires significant amounts of work just to keep that + code working. + + Code which is in the mainline, instead, does not require this work as the + result of a simple rule requiring any developer who makes an API change + to also fix any code that breaks as the result of that change. So code + which has been merged into the mainline has significantly lower + maintenance costs. + +- Beyond that, code which is in the kernel will often be improved by other + developers. Surprising results can come from empowering your user + community and customers to improve your product. + +- Kernel code is subjected to review, both before and after merging into + the mainline. No matter how strong the original developer's skills are, + this review process invariably finds ways in which the code can be + improved. Often review finds severe bugs and security problems. This is + especially true for code which has been developed in a closed + environment; such code benefits strongly from review by outside + developers. Out-of-tree code is lower-quality code. + +- Participation in the development process is your way to influence the + direction of kernel development. Users who complain from the sidelines + are heard, but active developers have a stronger voice - and the ability + to implement changes which make the kernel work better for their needs. + +- When code is maintained separately, the possibility that a third party + will contribute a different implementation of a similar feature always + exists. Should that happen, getting your code merged will become much + harder - to the point of impossibility. Then you will be faced with the + unpleasant alternatives of either (1) maintaining a nonstandard feature + out of tree indefinitely, or (2) abandoning your code and migrating your + users over to the in-tree version. + +- Contribution of code is the fundamental action which makes the whole + process work. By contributing your code you can add new functionality to + the kernel and provide capabilities and examples which are of use to + other kernel developers. If you have developed code for Linux (or are + thinking about doing so), you clearly have an interest in the continued + success of this platform; contributing code is one of the best ways to + help ensure that success. + +All of the reasoning above applies to any out-of-tree kernel code, +including code which is distributed in proprietary, binary-only form. +There are, however, additional factors which should be taken into account +before considering any sort of binary-only kernel code distribution. These +include: + +- The legal issues around the distribution of proprietary kernel modules + are cloudy at best; quite a few kernel copyright holders believe that + most binary-only modules are derived products of the kernel and that, as + a result, their distribution is a violation of the GNU General Public + license (about which more will be said below). Your author is not a + lawyer, and nothing in this document can possibly be considered to be + legal advice. The true legal status of closed-source modules can only be + determined by the courts. But the uncertainty which haunts those modules + is there regardless. + +- Binary modules greatly increase the difficulty of debugging kernel + problems, to the point that most kernel developers will not even try. So + the distribution of binary-only modules will make it harder for your + users to get support from the community. + +- Support is also harder for distributors of binary-only modules, who must + provide a version of the module for every distribution and every kernel + version they wish to support. Dozens of builds of a single module can + be required to provide reasonably comprehensive coverage, and your users + will have to upgrade your module separately every time they upgrade their + kernel. + +- Everything that was said above about code review applies doubly to + closed-source code. Since this code is not available at all, it cannot + have been reviewed by the community and will, beyond doubt, have serious + problems. + +Makers of embedded systems, in particular, may be tempted to disregard much +of what has been said in this section in the belief that they are shipping +a self-contained product which uses a frozen kernel version and requires no +more development after its release. This argument misses the value of +widespread code review and the value of allowing your users to add +capabilities to your product. But these products, too, have a limited +commercial life, after which a new version must be released. At that +point, vendors whose code is in the mainline and well maintained will be +much better positioned to get the new product ready for market quickly. + + +1.5: LICENSING + +Code is contributed to the Linux kernel under a number of licenses, but all +code must be compatible with version 2 of the GNU General Public License +(GPLv2), which is the license covering the kernel distribution as a whole. +In practice, that means that all code contributions are covered either by +GPLv2 (with, optionally, language allowing distribution under later +versions of the GPL) or the three-clause BSD license. Any contributions +which are not covered by a compatible license will not be accepted into the +kernel. + +Copyright assignments are not required (or requested) for code contributed +to the kernel. All code merged into the mainline kernel retains its +original ownership; as a result, the kernel now has thousands of owners. + +One implication of this ownership structure is that any attempt to change +the licensing of the kernel is doomed to almost certain failure. There are +few practical scenarios where the agreement of all copyright holders could +be obtained (or their code removed from the kernel). So, in particular, +there is no prospect of a migration to version 3 of the GPL in the +foreseeable future. + +It is imperative that all code contributed to the kernel be legitimately +free software. For that reason, code from anonymous (or pseudonymous) +contributors will not be accepted. All contributors are required to "sign +off" on their code, stating that the code can be distributed with the +kernel under the GPL. Code which has not been licensed as free software by +its owner, or which risks creating copyright-related problems for the +kernel (such as code which derives from reverse-engineering efforts lacking +proper safeguards) cannot be contributed. + +Questions about copyright-related issues are common on Linux development +mailing lists. Such questions will normally receive no shortage of +answers, but one should bear in mind that the people answering those +questions are not lawyers and cannot provide legal advice. If you have +legal questions relating to Linux source code, there is no substitute for +talking with a lawyer who understands this field. Relying on answers +obtained on technical mailing lists is a risky affair. diff --git a/trunk/Documentation/development-process/2.Process b/trunk/Documentation/development-process/2.Process new file mode 100644 index 000000000000..d750321acd5a --- /dev/null +++ b/trunk/Documentation/development-process/2.Process @@ -0,0 +1,459 @@ +2: HOW THE DEVELOPMENT PROCESS WORKS + +Linux kernel development in the early 1990's was a pretty loose affair, +with relatively small numbers of users and developers involved. With a +user base in the millions and with some 2,000 developers involved over the +course of one year, the kernel has since had to evolve a number of +processes to keep development happening smoothly. A solid understanding of +how the process works is required in order to be an effective part of it. + + +2.1: THE BIG PICTURE + +The kernel developers use a loosely time-based release process, with a new +major kernel release happening every two or three months. The recent +release history looks like this: + + 2.6.26 July 13, 2008 + 2.6.25 April 16, 2008 + 2.6.24 January 24, 2008 + 2.6.23 October 9, 2007 + 2.6.22 July 8, 2007 + 2.6.21 April 25, 2007 + 2.6.20 February 4, 2007 + +Every 2.6.x release is a major kernel release with new features, internal +API changes, and more. A typical 2.6 release can contain over 10,000 +changesets with changes to several hundred thousand lines of code. 2.6 is +thus the leading edge of Linux kernel development; the kernel uses a +rolling development model which is continually integrating major changes. + +A relatively straightforward discipline is followed with regard to the +merging of patches for each release. At the beginning of each development +cycle, the "merge window" is said to be open. At that time, code which is +deemed to be sufficiently stable (and which is accepted by the development +community) is merged into the mainline kernel. The bulk of changes for a +new development cycle (and all of the major changes) will be merged during +this time, at a rate approaching 1,000 changes ("patches," or "changesets") +per day. + +(As an aside, it is worth noting that the changes integrated during the +merge window do not come out of thin air; they have been collected, tested, +and staged ahead of time. How that process works will be described in +detail later on). + +The merge window lasts for two weeks. At the end of this time, Linus +Torvalds will declare that the window is closed and release the first of +the "rc" kernels. For the kernel which is destined to be 2.6.26, for +example, the release which happens at the end of the merge window will be +called 2.6.26-rc1. The -rc1 release is the signal that the time to merge +new features has passed, and that the time to stabilize the next kernel has +begun. + +Over the next six to ten weeks, only patches which fix problems should be +submitted to the mainline. On occasion a more significant change will be +allowed, but such occasions are rare; developers who try to merge new +features outside of the merge window tend to get an unfriendly reception. +As a general rule, if you miss the merge window for a given feature, the +best thing to do is to wait for the next development cycle. (An occasional +exception is made for drivers for previously-unsupported hardware; if they +touch no in-tree code, they cannot cause regressions and should be safe to +add at any time). + +As fixes make their way into the mainline, the patch rate will slow over +time. Linus releases new -rc kernels about once a week; a normal series +will get up to somewhere between -rc6 and -rc9 before the kernel is +considered to be sufficiently stable and the final 2.6.x release is made. +At that point the whole process starts over again. + +As an example, here is how the 2.6.25 development cycle went (all dates in +2008): + + January 24 2.6.24 stable release + February 10 2.6.25-rc1, merge window closes + February 15 2.6.25-rc2 + February 24 2.6.25-rc3 + March 4 2.6.25-rc4 + March 9 2.6.25-rc5 + March 16 2.6.25-rc6 + March 25 2.6.25-rc7 + April 1 2.6.25-rc8 + April 11 2.6.25-rc9 + April 16 2.6.25 stable release + +How do the developers decide when to close the development cycle and create +the stable release? The most significant metric used is the list of +regressions from previous releases. No bugs are welcome, but those which +break systems which worked in the past are considered to be especially +serious. For this reason, patches which cause regressions are looked upon +unfavorably and are quite likely to be reverted during the stabilization +period. + +The developers' goal is to fix all known regressions before the stable +release is made. In the real world, this kind of perfection is hard to +achieve; there are just too many variables in a project of this size. +There comes a point where delaying the final release just makes the problem +worse; the pile of changes waiting for the next merge window will grow +larger, creating even more regressions the next time around. So most 2.6.x +kernels go out with a handful of known regressions though, hopefully, none +of them are serious. + +Once a stable release is made, its ongoing maintenance is passed off to the +"stable team," currently comprised of Greg Kroah-Hartman and Chris Wright. +The stable team will release occasional updates to the stable release using +the 2.6.x.y numbering scheme. To be considered for an update release, a +patch must (1) fix a significant bug, and (2) already be merged into the +mainline for the next development kernel. Continuing our 2.6.25 example, +the history (as of this writing) is: + + May 1 2.6.25.1 + May 6 2.6.25.2 + May 9 2.6.25.3 + May 15 2.6.25.4 + June 7 2.6.25.5 + June 9 2.6.25.6 + June 16 2.6.25.7 + June 21 2.6.25.8 + June 24 2.6.25.9 + +Stable updates for a given kernel are made for approximately six months; +after that, the maintenance of stable releases is solely the responsibility +of the distributors which have shipped that particular kernel. + + +2.2: THE LIFECYCLE OF A PATCH + +Patches do not go directly from the developer's keyboard into the mainline +kernel. There is, instead, a somewhat involved (if somewhat informal) +process designed to ensure that each patch is reviewed for quality and that +each patch implements a change which is desirable to have in the mainline. +This process can happen quickly for minor fixes, or, in the case of large +and controversial changes, go on for years. Much developer frustration +comes from a lack of understanding of this process or from attempts to +circumvent it. + +In the hopes of reducing that frustration, this document will describe how +a patch gets into the kernel. What follows below is an introduction which +describes the process in a somewhat idealized way. A much more detailed +treatment will come in later sections. + +The stages that a patch goes through are, generally: + + - Design. This is where the real requirements for the patch - and the way + those requirements will be met - are laid out. Design work is often + done without involving the community, but it is better to do this work + in the open if at all possible; it can save a lot of time redesigning + things later. + + - Early review. Patches are posted to the relevant mailing list, and + developers on that list reply with any comments they may have. This + process should turn up any major problems with a patch if all goes + well. + + - Wider review. When the patch is getting close to ready for mainline + inclusion, it will be accepted by a relevant subsystem maintainer - + though this acceptance is not a guarantee that the patch will make it + all the way to the mainline. The patch will show up in the maintainer's + subsystem tree and into the staging trees (described below). When the + process works, this step leads to more extensive review of the patch and + the discovery of any problems resulting from the integration of this + patch with work being done by others. + + - Merging into the mainline. Eventually, a successful patch will be + merged into the mainline repository managed by Linus Torvalds. More + comments and/or problems may surface at this time; it is important that + the developer be responsive to these and fix any issues which arise. + + - Stable release. The number of users potentially affected by the patch + is now large, so, once again, new problems may arise. + + - Long-term maintenance. While it is certainly possible for a developer + to forget about code after merging it, that sort of behavior tends to + leave a poor impression in the development community. Merging code + eliminates some of the maintenance burden, in that others will fix + problems caused by API changes. But the original developer should + continue to take responsibility for the code if it is to remain useful + in the longer term. + +One of the largest mistakes made by kernel developers (or their employers) +is to try to cut the process down to a single "merging into the mainline" +step. This approach invariably leads to frustration for everybody +involved. + + +2.3: HOW PATCHES GET INTO THE KERNEL + +There is exactly one person who can merge patches into the mainline kernel +repository: Linus Torvalds. But, of the over 12,000 patches which went +into the 2.6.25 kernel, only 250 (around 2%) were directly chosen by Linus +himself. The kernel project has long since grown to a size where no single +developer could possibly inspect and select every patch unassisted. The +way the kernel developers have addressed this growth is through the use of +a lieutenant system built around a chain of trust. + +The kernel code base is logically broken down into a set of subsystems: +networking, specific architecture support, memory management, video +devices, etc. Most subsystems have a designated maintainer, a developer +who has overall responsibility for the code within that subsystem. These +subsystem maintainers are the gatekeepers (in a loose way) for the portion +of the kernel they manage; they are the ones who will (usually) accept a +patch for inclusion into the mainline kernel. + +Subsystem maintainers each manage their own version of the kernel source +tree, usually (but certainly not always) using the git source management +tool. Tools like git (and related tools like quilt or mercurial) allow +maintainers to track a list of patches, including authorship information +and other metadata. At any given time, the maintainer can identify which +patches in his or her repository are not found in the mainline. + +When the merge window opens, top-level maintainers will ask Linus to "pull" +the patches they have selected for merging from their repositories. If +Linus agrees, the stream of patches will flow up into his repository, +becoming part of the mainline kernel. The amount of attention that Linus +pays to specific patches received in a pull operation varies. It is clear +that, sometimes, he looks quite closely. But, as a general rule, Linus +trusts the subsystem maintainers to not send bad patches upstream. + +Subsystem maintainers, in turn, can pull patches from other maintainers. +For example, the networking tree is built from patches which accumulated +first in trees dedicated to network device drivers, wireless networking, +etc. This chain of repositories can be arbitrarily long, though it rarely +exceeds two or three links. Since each maintainer in the chain trusts +those managing lower-level trees, this process is known as the "chain of +trust." + +Clearly, in a system like this, getting patches into the kernel depends on +finding the right maintainer. Sending patches directly to Linus is not +normally the right way to go. + + +2.4: STAGING TREES + +The chain of subsystem trees guides the flow of patches into the kernel, +but it also raises an interesting question: what if somebody wants to look +at all of the patches which are being prepared for the next merge window? +Developers will be interested in what other changes are pending to see +whether there are any conflicts to worry about; a patch which changes a +core kernel function prototype, for example, will conflict with any other +patches which use the older form of that function. Reviewers and testers +want access to the changes in their integrated form before all of those +changes land in the mainline kernel. One could pull changes from all of +the interesting subsystem trees, but that would be a big and error-prone +job. + +The answer comes in the form of staging trees, where subsystem trees are +collected for testing and review. The older of these trees, maintained by +Andrew Morton, is called "-mm" (for memory management, which is how it got +started). The -mm tree integrates patches from a long list of subsystem +trees; it also has some patches aimed at helping with debugging. + +Beyond that, -mm contains a significant collection of patches which have +been selected by Andrew directly. These patches may have been posted on a +mailing list, or they may apply to a part of the kernel for which there is +no designated subsystem tree. As a result, -mm operates as a sort of +subsystem tree of last resort; if there is no other obvious path for a +patch into the mainline, it is likely to end up in -mm. Miscellaneous +patches which accumulate in -mm will eventually either be forwarded on to +an appropriate subsystem tree or be sent directly to Linus. In a typical +development cycle, approximately 10% of the patches going into the mainline +get there via -mm. + +The current -mm patch can always be found from the front page of + + http://kernel.org/ + +Those who want to see the current state of -mm can get the "-mm of the +moment" tree, found at: + + http://userweb.kernel.org/~akpm/mmotm/ + +Use of the MMOTM tree is likely to be a frustrating experience, though; +there is a definite chance that it will not even compile. + +The other staging tree, started more recently, is linux-next, maintained by +Stephen Rothwell. The linux-next tree is, by design, a snapshot of what +the mainline is expected to look like after the next merge window closes. +Linux-next trees are announced on the linux-kernel and linux-next mailing +lists when they are assembled; they can be downloaded from: + + http://www.kernel.org/pub/linux/kernel/people/sfr/linux-next/ + +Some information about linux-next has been gathered at: + + http://linux.f-seidel.de/linux-next/pmwiki/ + +How the linux-next tree will fit into the development process is still +changing. As of this writing, the first full development cycle involving +linux-next (2.6.26) is coming to an end; thus far, it has proved to be a +valuable resource for finding and fixing integration problems before the +beginning of the merge window. See http://lwn.net/Articles/287155/ for +more information on how linux-next has worked to set up the 2.6.27 merge +window. + +Some developers have begun to suggest that linux-next should be used as the +target for future development as well. The linux-next tree does tend to be +far ahead of the mainline and is more representative of the tree into which +any new work will be merged. The downside to this idea is that the +volatility of linux-next tends to make it a difficult development target. +See http://lwn.net/Articles/289013/ for more information on this topic, and +stay tuned; much is still in flux where linux-next is involved. + + +2.5: TOOLS + +As can be seen from the above text, the kernel development process depends +heavily on the ability to herd collections of patches in various +directions. The whole thing would not work anywhere near as well as it +does without suitably powerful tools. Tutorials on how to use these tools +are well beyond the scope of this document, but there is space for a few +pointers. + +By far the dominant source code management system used by the kernel +community is git. Git is one of a number of distributed version control +systems being developed in the free software community. It is well tuned +for kernel development, in that it performs quite well when dealing with +large repositories and large numbers of patches. It also has a reputation +for being difficult to learn and use, though it has gotten better over +time. Some sort of familiarity with git is almost a requirement for kernel +developers; even if they do not use it for their own work, they'll need git +to keep up with what other developers (and the mainline) are doing. + +Git is now packaged by almost all Linux distributions. There is a home +page at + + http://git.or.cz/ + +That page has pointers to documentation and tutorials. One should be +aware, in particular, of the Kernel Hacker's Guide to git, which has +information specific to kernel development: + + http://linux.yyz.us/git-howto.html + +Among the kernel developers who do not use git, the most popular choice is +almost certainly Mercurial: + + http://www.selenic.com/mercurial/ + +Mercurial shares many features with git, but it provides an interface which +many find easier to use. + +The other tool worth knowing about is Quilt: + + http://savannah.nongnu.org/projects/quilt/ + +Quilt is a patch management system, rather than a source code management +system. It does not track history over time; it is, instead, oriented +toward tracking a specific set of changes against an evolving code base. +Some major subsystem maintainers use quilt to manage patches intended to go +upstream. For the management of certain kinds of trees (-mm, for example), +quilt is the best tool for the job. + + +2.6: MAILING LISTS + +A great deal of Linux kernel development work is done by way of mailing +lists. It is hard to be a fully-functioning member of the community +without joining at least one list somewhere. But Linux mailing lists also +represent a potential hazard to developers, who risk getting buried under a +load of electronic mail, running afoul of the conventions used on the Linux +lists, or both. + +Most kernel mailing lists are run on vger.kernel.org; the master list can +be found at: + + http://vger.kernel.org/vger-lists.html + +There are lists hosted elsewhere, though; a number of them are at +lists.redhat.com. + +The core mailing list for kernel development is, of course, linux-kernel. +This list is an intimidating place to be; volume can reach 500 messages per +day, the amount of noise is high, the conversation can be severely +technical, and participants are not always concerned with showing a high +degree of politeness. But there is no other place where the kernel +development community comes together as a whole; developers who avoid this +list will miss important information. + +There are a few hints which can help with linux-kernel survival: + +- Have the list delivered to a separate folder, rather than your main + mailbox. One must be able to ignore the stream for sustained periods of + time. + +- Do not try to follow every conversation - nobody else does. It is + important to filter on both the topic of interest (though note that + long-running conversations can drift away from the original subject + without changing the email subject line) and the people who are + participating. + +- Do not feed the trolls. If somebody is trying to stir up an angry + response, ignore them. + +- When responding to linux-kernel email (or that on other lists) preserve + the Cc: header for all involved. In the absence of a strong reason (such + as an explicit request), you should never remove recipients. Always make + sure that the person you are responding to is in the Cc: list. This + convention also makes it unnecessary to explicitly ask to be copied on + replies to your postings. + +- Search the list archives (and the net as a whole) before asking + questions. Some developers can get impatient with people who clearly + have not done their homework. + +- Avoid top-posting (the practice of putting your answer above the quoted + text you are responding to). It makes your response harder to read and + makes a poor impression. + +- Ask on the correct mailing list. Linux-kernel may be the general meeting + point, but it is not the best place to find developers from all + subsystems. + +The last point - finding the correct mailing list - is a common place for +beginning developers to go wrong. Somebody who asks a networking-related +question on linux-kernel will almost certainly receive a polite suggestion +to ask on the netdev list instead, as that is the list frequented by most +networking developers. Other lists exist for the SCSI, video4linux, IDE, +filesystem, etc. subsystems. The best place to look for mailing lists is +in the MAINTAINERS file packaged with the kernel source. + + +2.7: GETTING STARTED WITH KERNEL DEVELOPMENT + +Questions about how to get started with the kernel development process are +common - from both individuals and companies. Equally common are missteps +which make the beginning of the relationship harder than it has to be. + +Companies often look to hire well-known developers to get a development +group started. This can, in fact, be an effective technique. But it also +tends to be expensive and does not do much to grow the pool of experienced +kernel developers. It is possible to bring in-house developers up to speed +on Linux kernel development, given the investment of a bit of time. Taking +this time can endow an employer with a group of developers who understand +the kernel and the company both, and who can help to train others as well. +Over the medium term, this is often the more profitable approach. + +Individual developers are often, understandably, at a loss for a place to +start. Beginning with a large project can be intimidating; one often wants +to test the waters with something smaller first. This is the point where +some developers jump into the creation of patches fixing spelling errors or +minor coding style issues. Unfortunately, such patches create a level of +noise which is distracting for the development community as a whole, so, +increasingly, they are looked down upon. New developers wishing to +introduce themselves to the community will not get the sort of reception +they wish for by these means. + +Andrew Morton gives this advice for aspiring kernel developers + + The #1 project for all kernel beginners should surely be "make sure + that the kernel runs perfectly at all times on all machines which + you can lay your hands on". Usually the way to do this is to work + with others on getting things fixed up (this can require + persistence!) but that's fine - it's a part of kernel development. + +(http://lwn.net/Articles/283982/). + +In the absence of obvious problems to fix, developers are advised to look +at the current lists of regressions and open bugs in general. There is +never any shortage of issues in need of fixing; by addressing these issues, +developers will gain experience with the process while, at the same time, +building respect with the rest of the development community. diff --git a/trunk/Documentation/development-process/3.Early-stage b/trunk/Documentation/development-process/3.Early-stage new file mode 100644 index 000000000000..307a159a70ca --- /dev/null +++ b/trunk/Documentation/development-process/3.Early-stage @@ -0,0 +1,195 @@ +3: EARLY-STAGE PLANNING + +When contemplating a Linux kernel development project, it can be tempting +to jump right in and start coding. As with any significant project, +though, much of the groundwork for success is best laid before the first +line of code is written. Some time spent in early planning and +communication can save far more time later on. + + +3.1: SPECIFYING THE PROBLEM + +Like any engineering project, a successful kernel enhancement starts with a +clear description of the problem to be solved. In some cases, this step is +easy: when a driver is needed for a specific piece of hardware, for +example. In others, though, it is tempting to confuse the real problem +with the proposed solution, and that can lead to difficulties. + +Consider an example: some years ago, developers working with Linux audio +sought a way to run applications without dropouts or other artifacts caused +by excessive latency in the system. The solution they arrived at was a +kernel module intended to hook into the Linux Security Module (LSM) +framework; this module could be configured to give specific applications +access to the realtime scheduler. This module was implemented and sent to +the linux-kernel mailing list, where it immediately ran into problems. + +To the audio developers, this security module was sufficient to solve their +immediate problem. To the wider kernel community, though, it was seen as a +misuse of the LSM framework (which is not intended to confer privileges +onto processes which they would not otherwise have) and a risk to system +stability. Their preferred solutions involved realtime scheduling access +via the rlimit mechanism for the short term, and ongoing latency reduction +work in the long term. + +The audio community, however, could not see past the particular solution +they had implemented; they were unwilling to accept alternatives. The +resulting disagreement left those developers feeling disillusioned with the +entire kernel development process; one of them went back to an audio list +and posted this: + + There are a number of very good Linux kernel developers, but they + tend to get outshouted by a large crowd of arrogant fools. Trying + to communicate user requirements to these people is a waste of + time. They are much too "intelligent" to listen to lesser mortals. + +(http://lwn.net/Articles/131776/). + +The reality of the situation was different; the kernel developers were far +more concerned about system stability, long-term maintenance, and finding +the right solution to the problem than they were with a specific module. +The moral of the story is to focus on the problem - not a specific solution +- and to discuss it with the development community before investing in the +creation of a body of code. + +So, when contemplating a kernel development project, one should obtain +answers to a short set of questions: + + - What, exactly, is the problem which needs to be solved? + + - Who are the users affected by this problem? Which use cases should the + solution address? + + - How does the kernel fall short in addressing that problem now? + +Only then does it make sense to start considering possible solutions. + + +3.2: EARLY DISCUSSION + +When planning a kernel development project, it makes great sense to hold +discussions with the community before launching into implementation. Early +communication can save time and trouble in a number of ways: + + - It may well be that the problem is addressed by the kernel in ways which + you have not understood. The Linux kernel is large and has a number of + features and capabilities which are not immediately obvious. Not all + kernel capabilities are documented as well as one might like, and it is + easy to miss things. Your author has seen the posting of a complete + driver which duplicated an existing driver that the new author had been + unaware of. Code which reinvents existing wheels is not only wasteful; + it will also not be accepted into the mainline kernel. + + - There may be elements of the proposed solution which will not be + acceptable for mainline merging. It is better to find out about + problems like this before writing the code. + + - It's entirely possible that other developers have thought about the + problem; they may have ideas for a better solution, and may be willing + to help in the creation of that solution. + +Years of experience with the kernel development community have taught a +clear lesson: kernel code which is designed and developed behind closed +doors invariably has problems which are only revealed when the code is +released into the community. Sometimes these problems are severe, +requiring months or years of effort before the code can be brought up to +the kernel community's standards. Some examples include: + + - The Devicescape network stack was designed and implemented for + single-processor systems. It could not be merged into the mainline + until it was made suitable for multiprocessor systems. Retrofitting + locking and such into code is a difficult task; as a result, the merging + of this code (now called mac80211) was delayed for over a year. + + - The Reiser4 filesystem included a number of capabilities which, in the + core kernel developers' opinion, should have been implemented in the + virtual filesystem layer instead. It also included features which could + not easily be implemented without exposing the system to user-caused + deadlocks. The late revelation of these problems - and refusal to + address some of them - has caused Reiser4 to stay out of the mainline + kernel. + + - The AppArmor security module made use of internal virtual filesystem + data structures in ways which were considered to be unsafe and + unreliable. This code has since been significantly reworked, but + remains outside of the mainline. + +In each of these cases, a great deal of pain and extra work could have been +avoided with some early discussion with the kernel developers. + + +3.3: WHO DO YOU TALK TO? + +When developers decide to take their plans public, the next question will +be: where do we start? The answer is to find the right mailing list(s) and +the right maintainer. For mailing lists, the best approach is to look in +the MAINTAINERS file for a relevant place to post. If there is a suitable +subsystem list, posting there is often preferable to posting on +linux-kernel; you are more likely to reach developers with expertise in the +relevant subsystem and the environment may be more supportive. + +Finding maintainers can be a bit harder. Again, the MAINTAINERS file is +the place to start. That file tends to not always be up to date, though, +and not all subsystems are represented there. The person listed in the +MAINTAINERS file may, in fact, not be the person who is actually acting in +that role currently. So, when there is doubt about who to contact, a +useful trick is to use git (and "git log" in particular) to see who is +currently active within the subsystem of interest. Look at who is writing +patches, and who, if anybody, is attaching Signed-off-by lines to those +patches. Those are the people who will be best placed to help with a new +development project. + +If all else fails, talking to Andrew Morton can be an effective way to +track down a maintainer for a specific piece of code. + + +3.4: WHEN TO POST? + +If possible, posting your plans during the early stages can only be +helpful. Describe the problem being solved and any plans that have been +made on how the implementation will be done. Any information you can +provide can help the development community provide useful input on the +project. + +One discouraging thing which can happen at this stage is not a hostile +reaction, but, instead, little or no reaction at all. The sad truth of the +matter is (1) kernel developers tend to be busy, (2) there is no shortage +of people with grand plans and little code (or even prospect of code) to +back them up, and (3) nobody is obligated to review or comment on ideas +posted by others. If a request-for-comments posting yields little in the +way of comments, do not assume that it means there is no interest in the +project. Unfortunately, you also cannot assume that there are no problems +with your idea. The best thing to do in this situation is to proceed, +keeping the community informed as you go. + + +3.5: GETTING OFFICIAL BUY-IN + +If your work is being done in a corporate environment - as most Linux +kernel work is - you must, obviously, have permission from suitably +empowered managers before you can post your company's plans or code to a +public mailing list. The posting of code which has not been cleared for +release under a GPL-compatible license can be especially problematic; the +sooner that a company's management and legal staff can agree on the posting +of a kernel development project, the better off everybody involved will be. + +Some readers may be thinking at this point that their kernel work is +intended to support a product which does not yet have an officially +acknowledged existence. Revealing their employer's plans on a public +mailing list may not be a viable option. In cases like this, it is worth +considering whether the secrecy is really necessary; there is often no real +need to keep development plans behind closed doors. + +That said, there are also cases where a company legitimately cannot +disclose its plans early in the development process. Companies with +experienced kernel developers may choose to proceed in an open-loop manner +on the assumption that they will be able to avoid serious integration +problems later. For companies without that sort of in-house expertise, the +best option is often to hire an outside developer to review the plans under +a non-disclosure agreement. The Linux Foundation operates an NDA program +designed to help with this sort of situation; more information can be found +at: + + http://www.linuxfoundation.org/en/NDA_program + +This kind of review is often enough to avoid serious problems later on +without requiring public disclosure of the project. diff --git a/trunk/Documentation/development-process/4.Coding b/trunk/Documentation/development-process/4.Coding new file mode 100644 index 000000000000..014aca8f14e2 --- /dev/null +++ b/trunk/Documentation/development-process/4.Coding @@ -0,0 +1,384 @@ +4: GETTING THE CODE RIGHT + +While there is much to be said for a solid and community-oriented design +process, the proof of any kernel development project is in the resulting +code. It is the code which will be examined by other developers and merged +(or not) into the mainline tree. So it is the quality of this code which +will determine the ultimate success of the project. + +This section will examine the coding process. We'll start with a look at a +number of ways in which kernel developers can go wrong. Then the focus +will shift toward doing things right and the tools which can help in that +quest. + + +4.1: PITFALLS + +* Coding style + +The kernel has long had a standard coding style, described in +Documentation/CodingStyle. For much of that time, the policies described +in that file were taken as being, at most, advisory. As a result, there is +a substantial amount of code in the kernel which does not meet the coding +style guidelines. The presence of that code leads to two independent +hazards for kernel developers. + +The first of these is to believe that the kernel coding standards do not +matter and are not enforced. The truth of the matter is that adding new +code to the kernel is very difficult if that code is not coded according to +the standard; many developers will request that the code be reformatted +before they will even review it. A code base as large as the kernel +requires some uniformity of code to make it possible for developers to +quickly understand any part of it. So there is no longer room for +strangely-formatted code. + +Occasionally, the kernel's coding style will run into conflict with an +employer's mandated style. In such cases, the kernel's style will have to +win before the code can be merged. Putting code into the kernel means +giving up a degree of control in a number of ways - including control over +how the code is formatted. + +The other trap is to assume that code which is already in the kernel is +urgently in need of coding style fixes. Developers may start to generate +reformatting patches as a way of gaining familiarity with the process, or +as a way of getting their name into the kernel changelogs - or both. But +pure coding style fixes are seen as noise by the development community; +they tend to get a chilly reception. So this type of patch is best +avoided. It is natural to fix the style of a piece of code while working +on it for other reasons, but coding style changes should not be made for +their own sake. + +The coding style document also should not be read as an absolute law which +can never be transgressed. If there is a good reason to go against the +style (a line which becomes far less readable if split to fit within the +80-column limit, for example), just do it. + + +* Abstraction layers + +Computer Science professors teach students to make extensive use of +abstraction layers in the name of flexibility and information hiding. +Certainly the kernel makes extensive use of abstraction; no project +involving several million lines of code could do otherwise and survive. +But experience has shown that excessive or premature abstraction can be +just as harmful as premature optimization. Abstraction should be used to +the level required and no further. + +At a simple level, consider a function which has an argument which is +always passed as zero by all callers. One could retain that argument just +in case somebody eventually needs to use the extra flexibility that it +provides. By that time, though, chances are good that the code which +implements this extra argument has been broken in some subtle way which was +never noticed - because it has never been used. Or, when the need for +extra flexibility arises, it does not do so in a way which matches the +programmer's early expectation. Kernel developers will routinely submit +patches to remove unused arguments; they should, in general, not be added +in the first place. + +Abstraction layers which hide access to hardware - often to allow the bulk +of a driver to be used with multiple operating systems - are especially +frowned upon. Such layers obscure the code and may impose a performance +penalty; they do not belong in the Linux kernel. + +On the other hand, if you find yourself copying significant amounts of code +from another kernel subsystem, it is time to ask whether it would, in fact, +make sense to pull out some of that code into a separate library or to +implement that functionality at a higher level. There is no value in +replicating the same code throughout the kernel. + + +* #ifdef and preprocessor use in general + +The C preprocessor seems to present a powerful temptation to some C +programmers, who see it as a way to efficiently encode a great deal of +flexibility into a source file. But the preprocessor is not C, and heavy +use of it results in code which is much harder for others to read and +harder for the compiler to check for correctness. Heavy preprocessor use +is almost always a sign of code which needs some cleanup work. + +Conditional compilation with #ifdef is, indeed, a powerful feature, and it +is used within the kernel. But there is little desire to see code which is +sprinkled liberally with #ifdef blocks. As a general rule, #ifdef use +should be confined to header files whenever possible. +Conditionally-compiled code can be confined to functions which, if the code +is not to be present, simply become empty. The compiler will then quietly +optimize out the call to the empty function. The result is far cleaner +code which is easier to follow. + +C preprocessor macros present a number of hazards, including possible +multiple evaluation of expressions with side effects and no type safety. +If you are tempted to define a macro, consider creating an inline function +instead. The code which results will be the same, but inline functions are +easier to read, do not evaluate their arguments multiple times, and allow +the compiler to perform type checking on the arguments and return value. + + +* Inline functions + +Inline functions present a hazard of their own, though. Programmers can +become enamored of the perceived efficiency inherent in avoiding a function +call and fill a source file with inline functions. Those functions, +however, can actually reduce performance. Since their code is replicated +at each call site, they end up bloating the size of the compiled kernel. +That, in turn, creates pressure on the processor's memory caches, which can +slow execution dramatically. Inline functions, as a rule, should be quite +small and relatively rare. The cost of a function call, after all, is not +that high; the creation of large numbers of inline functions is a classic +example of premature optimization. + +In general, kernel programmers ignore cache effects at their peril. The +classic time/space tradeoff taught in beginning data structures classes +often does not apply to contemporary hardware. Space *is* time, in that a +larger program will run slower than one which is more compact. + + +* Locking + +In May, 2006, the "Devicescape" networking stack was, with great +fanfare, released under the GPL and made available for inclusion in the +mainline kernel. This donation was welcome news; support for wireless +networking in Linux was considered substandard at best, and the Devicescape +stack offered the promise of fixing that situation. Yet, this code did not +actually make it into the mainline until June, 2007 (2.6.22). What +happened? + +This code showed a number of signs of having been developed behind +corporate doors. But one large problem in particular was that it was not +designed to work on multiprocessor systems. Before this networking stack +(now called mac80211) could be merged, a locking scheme needed to be +retrofitted onto it. + +Once upon a time, Linux kernel code could be developed without thinking +about the concurrency issues presented by multiprocessor systems. Now, +however, this document is being written on a dual-core laptop. Even on +single-processor systems, work being done to improve responsiveness will +raise the level of concurrency within the kernel. The days when kernel +code could be written without thinking about locking are long past. + +Any resource (data structures, hardware registers, etc.) which could be +accessed concurrently by more than one thread must be protected by a lock. +New code should be written with this requirement in mind; retrofitting +locking after the fact is a rather more difficult task. Kernel developers +should take the time to understand the available locking primitives well +enough to pick the right tool for the job. Code which shows a lack of +attention to concurrency will have a difficult path into the mainline. + + +* Regressions + +One final hazard worth mentioning is this: it can be tempting to make a +change (which may bring big improvements) which causes something to break +for existing users. This kind of change is called a "regression," and +regressions have become most unwelcome in the mainline kernel. With few +exceptions, changes which cause regressions will be backed out if the +regression cannot be fixed in a timely manner. Far better to avoid the +regression in the first place. + +It is often argued that a regression can be justified if it causes things +to work for more people than it creates problems for. Why not make a +change if it brings new functionality to ten systems for each one it +breaks? The best answer to this question was expressed by Linus in July, +2007: + + So we don't fix bugs by introducing new problems. That way lies + madness, and nobody ever knows if you actually make any real + progress at all. Is it two steps forwards, one step back, or one + step forward and two steps back? + +(http://lwn.net/Articles/243460/). + +An especially unwelcome type of regression is any sort of change to the +user-space ABI. Once an interface has been exported to user space, it must +be supported indefinitely. This fact makes the creation of user-space +interfaces particularly challenging: since they cannot be changed in +incompatible ways, they must be done right the first time. For this +reason, a great deal of thought, clear documentation, and wide review for +user-space interfaces is always required. + + + +4.2: CODE CHECKING TOOLS + +For now, at least, the writing of error-free code remains an ideal that few +of us can reach. What we can hope to do, though, is to catch and fix as +many of those errors as possible before our code goes into the mainline +kernel. To that end, the kernel developers have put together an impressive +array of tools which can catch a wide variety of obscure problems in an +automated way. Any problem caught by the computer is a problem which will +not afflict a user later on, so it stands to reason that the automated +tools should be used whenever possible. + +The first step is simply to heed the warnings produced by the compiler. +Contemporary versions of gcc can detect (and warn about) a large number of +potential errors. Quite often, these warnings point to real problems. +Code submitted for review should, as a rule, not produce any compiler +warnings. When silencing warnings, take care to understand the real cause +and try to avoid "fixes" which make the warning go away without addressing +its cause. + +Note that not all compiler warnings are enabled by default. Build the +kernel with "make EXTRA_CFLAGS=-W" to get the full set. + +The kernel provides several configuration options which turn on debugging +features; most of these are found in the "kernel hacking" submenu. Several +of these options should be turned on for any kernel used for development or +testing purposes. In particular, you should turn on: + + - ENABLE_WARN_DEPRECATED, ENABLE_MUST_CHECK, and FRAME_WARN to get an + extra set of warnings for problems like the use of deprecated interfaces + or ignoring an important return value from a function. The output + generated by these warnings can be verbose, but one need not worry about + warnings from other parts of the kernel. + + - DEBUG_OBJECTS will add code to track the lifetime of various objects + created by the kernel and warn when things are done out of order. If + you are adding a subsystem which creates (and exports) complex objects + of its own, consider adding support for the object debugging + infrastructure. + + - DEBUG_SLAB can find a variety of memory allocation and use errors; it + should be used on most development kernels. + + - DEBUG_SPINLOCK, DEBUG_SPINLOCK_SLEEP, and DEBUG_MUTEXES will find a + number of common locking errors. + +There are quite a few other debugging options, some of which will be +discussed below. Some of them have a significant performance impact and +should not be used all of the time. But some time spent learning the +available options will likely be paid back many times over in short order. + +One of the heavier debugging tools is the locking checker, or "lockdep." +This tool will track the acquisition and release of every lock (spinlock or +mutex) in the system, the order in which locks are acquired relative to +each other, the current interrupt environment, and more. It can then +ensure that locks are always acquired in the same order, that the same +interrupt assumptions apply in all situations, and so on. In other words, +lockdep can find a number of scenarios in which the system could, on rare +occasion, deadlock. This kind of problem can be painful (for both +developers and users) in a deployed system; lockdep allows them to be found +in an automated manner ahead of time. Code with any sort of non-trivial +locking should be run with lockdep enabled before being submitted for +inclusion. + +As a diligent kernel programmer, you will, beyond doubt, check the return +status of any operation (such as a memory allocation) which can fail. The +fact of the matter, though, is that the resulting failure recovery paths +are, probably, completely untested. Untested code tends to be broken code; +you could be much more confident of your code if all those error-handling +paths had been exercised a few times. + +The kernel provides a fault injection framework which can do exactly that, +especially where memory allocations are involved. With fault injection +enabled, a configurable percentage of memory allocations will be made to +fail; these failures can be restricted to a specific range of code. +Running with fault injection enabled allows the programmer to see how the +code responds when things go badly. See +Documentation/fault-injection/fault-injection.text for more information on +how to use this facility. + +Other kinds of errors can be found with the "sparse" static analysis tool. +With sparse, the programmer can be warned about confusion between +user-space and kernel-space addresses, mixture of big-endian and +small-endian quantities, the passing of integer values where a set of bit +flags is expected, and so on. Sparse must be installed separately (it can +be found at http://www.kernel.org/pub/software/devel/sparse/ if your +distributor does not package it); it can then be run on the code by adding +"C=1" to your make command. + +Other kinds of portability errors are best found by compiling your code for +other architectures. If you do not happen to have an S/390 system or a +Blackfin development board handy, you can still perform the compilation +step. A large set of cross compilers for x86 systems can be found at + + http://www.kernel.org/pub/tools/crosstool/ + +Some time spent installing and using these compilers will help avoid +embarrassment later. + + +4.3: DOCUMENTATION + +Documentation has often been more the exception than the rule with kernel +development. Even so, adequate documentation will help to ease the merging +of new code into the kernel, make life easier for other developers, and +will be helpful for your users. In many cases, the addition of +documentation has become essentially mandatory. + +The first piece of documentation for any patch is its associated +changelog. Log entries should describe the problem being solved, the form +of the solution, the people who worked on the patch, any relevant +effects on performance, and anything else that might be needed to +understand the patch. + +Any code which adds a new user-space interface - including new sysfs or +/proc files - should include documentation of that interface which enables +user-space developers to know what they are working with. See +Documentation/ABI/README for a description of how this documentation should +be formatted and what information needs to be provided. + +The file Documentation/kernel-parameters.txt describes all of the kernel's +boot-time parameters. Any patch which adds new parameters should add the +appropriate entries to this file. + +Any new configuration options must be accompanied by help text which +clearly explains the options and when the user might want to select them. + +Internal API information for many subsystems is documented by way of +specially-formatted comments; these comments can be extracted and formatted +in a number of ways by the "kernel-doc" script. If you are working within +a subsystem which has kerneldoc comments, you should maintain them and add +them, as appropriate, for externally-available functions. Even in areas +which have not been so documented, there is no harm in adding kerneldoc +comments for the future; indeed, this can be a useful activity for +beginning kernel developers. The format of these comments, along with some +information on how to create kerneldoc templates can be found in the file +Documentation/kernel-doc-nano-HOWTO.txt. + +Anybody who reads through a significant amount of existing kernel code will +note that, often, comments are most notable by their absence. Once again, +the expectations for new code are higher than they were in the past; +merging uncommented code will be harder. That said, there is little desire +for verbosely-commented code. The code should, itself, be readable, with +comments explaining the more subtle aspects. + +Certain things should always be commented. Uses of memory barriers should +be accompanied by a line explaining why the barrier is necessary. The +locking rules for data structures generally need to be explained somewhere. +Major data structures need comprehensive documentation in general. +Non-obvious dependencies between separate bits of code should be pointed +out. Anything which might tempt a code janitor to make an incorrect +"cleanup" needs a comment saying why it is done the way it is. And so on. + + +4.4: INTERNAL API CHANGES + +The binary interface provided by the kernel to user space cannot be broken +except under the most severe circumstances. The kernel's internal +programming interfaces, instead, are highly fluid and can be changed when +the need arises. If you find yourself having to work around a kernel API, +or simply not using a specific functionality because it does not meet your +needs, that may be a sign that the API needs to change. As a kernel +developer, you are empowered to make such changes. + +There are, of course, some catches. API changes can be made, but they need +to be well justified. So any patch making an internal API change should be +accompanied by a description of what the change is and why it is +necessary. This kind of change should also be broken out into a separate +patch, rather than buried within a larger patch. + +The other catch is that a developer who changes an internal API is +generally charged with the task of fixing any code within the kernel tree +which is broken by the change. For a widely-used function, this duty can +lead to literally hundreds or thousands of changes - many of which are +likely to conflict with work being done by other developers. Needless to +say, this can be a large job, so it is best to be sure that the +justification is solid. + +When making an incompatible API change, one should, whenever possible, +ensure that code which has not been updated is caught by the compiler. +This will help you to be sure that you have found all in-tree uses of that +interface. It will also alert developers of out-of-tree code that there is +a change that they need to respond to. Supporting out-of-tree code is not +something that kernel developers need to be worried about, but we also do +not have to make life harder for out-of-tree developers than it it needs to +be. diff --git a/trunk/Documentation/development-process/5.Posting b/trunk/Documentation/development-process/5.Posting new file mode 100644 index 000000000000..dd48132a74dd --- /dev/null +++ b/trunk/Documentation/development-process/5.Posting @@ -0,0 +1,278 @@ +5: POSTING PATCHES + +Sooner or later, the time comes when your work is ready to be presented to +the community for review and, eventually, inclusion into the mainline +kernel. Unsurprisingly, the kernel development community has evolved a set +of conventions and procedures which are used in the posting of patches; +following them will make life much easier for everybody involved. This +document will attempt to cover these expectations in reasonable detail; +more information can also be found in the files SubmittingPatches, +SubmittingDrivers, and SubmitChecklist in the kernel documentation +directory. + + +5.1: WHEN TO POST + +There is a constant temptation to avoid posting patches before they are +completely "ready." For simple patches, that is not a problem. If the +work being done is complex, though, there is a lot to be gained by getting +feedback from the community before the work is complete. So you should +consider posting in-progress work, or even making a git tree available so +that interested developers can catch up with your work at any time. + +When posting code which is not yet considered ready for inclusion, it is a +good idea to say so in the posting itself. Also mention any major work +which remains to be done and any known problems. Fewer people will look at +patches which are known to be half-baked, but those who do will come in +with the idea that they can help you drive the work in the right direction. + + +5.2: BEFORE CREATING PATCHES + +There are a number of things which should be done before you consider +sending patches to the development community. These include: + + - Test the code to the extent that you can. Make use of the kernel's + debugging tools, ensure that the kernel will build with all reasonable + combinations of configuration options, use cross-compilers to build for + different architectures, etc. + + - Make sure your code is compliant with the kernel coding style + guidelines. + + - Does your change have performance implications? If so, you should run + benchmarks showing what the impact (or benefit) of your change is; a + summary of the results should be included with the patch. + + - Be sure that you have the right to post the code. If this work was done + for an employer, the employer likely has a right to the work and must be + agreeable with its release under the GPL. + +As a general rule, putting in some extra thought before posting code almost +always pays back the effort in short order. + + +5.3: PATCH PREPARATION + +The preparation of patches for posting can be a surprising amount of work, +but, once again, attempting to save time here is not generally advisable +even in the short term. + +Patches must be prepared against a specific version of the kernel. As a +general rule, a patch should be based on the current mainline as found in +Linus's git tree. It may become necessary to make versions against -mm, +linux-next, or a subsystem tree, though, to facilitate wider testing and +review. Depending on the area of your patch and what is going on +elsewhere, basing a patch against these other trees can require a +significant amount of work resolving conflicts and dealing with API +changes. + +Only the most simple changes should be formatted as a single patch; +everything else should be made as a logical series of changes. Splitting +up patches is a bit of an art; some developers spend a long time figuring +out how to do it in the way that the community expects. There are a few +rules of thumb, however, which can help considerably: + + - The patch series you post will almost certainly not be the series of + changes found in your working revision control system. Instead, the + changes you have made need to be considered in their final form, then + split apart in ways which make sense. The developers are interested in + discrete, self-contained changes, not the path you took to get to those + changes. + + - Each logically independent change should be formatted as a separate + patch. These changes can be small ("add a field to this structure") or + large (adding a significant new driver, for example), but they should be + conceptually small and amenable to a one-line description. Each patch + should make a specific change which can be reviewed on its own and + verified to do what it says it does. + + - As a way of restating the guideline above: do not mix different types of + changes in the same patch. If a single patch fixes a critical security + bug, rearranges a few structures, and reformats the code, there is a + good chance that it will be passed over and the important fix will be + lost. + + - Each patch should yield a kernel which builds and runs properly; if your + patch series is interrupted in the middle, the result should still be a + working kernel. Partial application of a patch series is a common + scenario when the "git bisect" tool is used to find regressions; if the + result is a broken kernel, you will make life harder for developers and + users who are engaging in the noble work of tracking down problems. + + - Do not overdo it, though. One developer recently posted a set of edits + to a single file as 500 separate patches - an act which did not make him + the most popular person on the kernel mailing list. A single patch can + be reasonably large as long as it still contains a single *logical* + change. + + - It can be tempting to add a whole new infrastructure with a series of + patches, but to leave that infrastructure unused until the final patch + in the series enables the whole thing. This temptation should be + avoided if possible; if that series adds regressions, bisection will + finger the last patch as the one which caused the problem, even though + the real bug is elsewhere. Whenever possible, a patch which adds new + code should make that code active immediately. + +Working to create the perfect patch series can be a frustrating process +which takes quite a bit of time and thought after the "real work" has been +done. When done properly, though, it is time well spent. + + +5.4: PATCH FORMATTING + +So now you have a perfect series of patches for posting, but the work is +not done quite yet. Each patch needs to be formatted into a message which +quickly and clearly communicates its purpose to the rest of the world. To +that end, each patch will be composed of the following: + + - An optional "From" line naming the author of the patch. This line is + only necessary if you are passing on somebody else's patch via email, + but it never hurts to add it when in doubt. + + - A one-line description of what the patch does. This message should be + enough for a reader who sees it with no other context to figure out the + scope of the patch; it is the line that will show up in the "short form" + changelogs. This message is usually formatted with the relevant + subsystem name first, followed by the purpose of the patch. For + example: + + gpio: fix build on CONFIG_GPIO_SYSFS=n + + - A blank line followed by a detailed description of the contents of the + patch. This description can be as long as is required; it should say + what the patch does and why it should be applied to the kernel. + + - One or more tag lines, with, at a minimum, one Signed-off-by: line from + the author of the patch. Tags will be described in more detail below. + +The above three items should, normally, be the text used when committing +the change to a revision control system. They are followed by: + + - The patch itself, in the unified ("-u") patch format. Using the "-p" + option to diff will associate function names with changes, making the + resulting patch easier for others to read. + +You should avoid including changes to irrelevant files (those generated by +the build process, for example, or editor backup files) in the patch. The +file "dontdiff" in the Documentation directory can help in this regard; +pass it to diff with the "-X" option. + +The tags mentioned above are used to describe how various developers have +been associated with the development of this patch. They are described in +detail in the SubmittingPatches document; what follows here is a brief +summary. Each of these lines has the format: + + tag: Full Name optional-other-stuff + +The tags in common use are: + + - Signed-off-by: this is a developer's certification that he or she has + the right to submit the patch for inclusion into the kernel. It is an + agreement to the Developer's Certificate of Origin, the full text of + which can be found in Documentation/SubmittingPatches. Code without a + proper signoff cannot be merged into the mainline. + + - Acked-by: indicates an agreement by another developer (often a + maintainer of the relevant code) that the patch is appropriate for + inclusion into the kernel. + + - Tested-by: states that the named person has tested the patch and found + it to work. + + - Reviewed-by: the named developer has reviewed the patch for correctness; + see the reviewer's statement in Documentation/SubmittingPatches for more + detail. + + - Reported-by: names a user who reported a problem which is fixed by this + patch; this tag is used to give credit to the (often underappreciated) + people who test our code and let us know when things do not work + correctly. + + - Cc: the named person received a copy of the patch and had the + opportunity to comment on it. + +Be careful in the addition of tags to your patches: only Cc: is appropriate +for addition without the explicit permission of the person named. + + +5.5: SENDING THE PATCH + +Before you mail your patches, there are a couple of other things you should +take care of: + + - Are you sure that your mailer will not corrupt the patches? Patches + which have had gratuitous white-space changes or line wrapping performed + by the mail client will not apply at the other end, and often will not + be examined in any detail. If there is any doubt at all, mail the patch + to yourself and convince yourself that it shows up intact. + + Documentation/email-clients.txt has some helpful hints on making + specific mail clients work for sending patches. + + - Are you sure your patch is free of silly mistakes? You should always + run patches through scripts/checkpatch.pl and address the complaints it + comes up with. Please bear in mind that checkpatch.pl, while being the + embodiment of a fair amount of thought about what kernel patches should + look like, is not smarter than you. If fixing a checkpatch.pl complaint + would make the code worse, don't do it. + +Patches should always be sent as plain text. Please do not send them as +attachments; that makes it much harder for reviewers to quote sections of +the patch in their replies. Instead, just put the patch directly into your +message. + +When mailing patches, it is important to send copies to anybody who might +be interested in it. Unlike some other projects, the kernel encourages +people to err on the side of sending too many copies; don't assume that the +relevant people will see your posting on the mailing lists. In particular, +copies should go to: + + - The maintainer(s) of the affected subsystem(s). As described earlier, + the MAINTAINERS file is the first place to look for these people. + + - Other developers who have been working in the same area - especially + those who might be working there now. Using git to see who else has + modified the files you are working on can be helpful. + + - If you are responding to a bug report or a feature request, copy the + original poster as well. + + - Send a copy to the relevant mailing list, or, if nothing else applies, + the linux-kernel list. + + - If you are fixing a bug, think about whether the fix should go into the + next stable update. If so, stable@kernel.org should get a copy of the + patch. Also add a "Cc: stable@kernel.org" to the tags within the patch + itself; that will cause the stable team to get a notification when your + fix goes into the mainline. + +When selecting recipients for a patch, it is good to have an idea of who +you think will eventually accept the patch and get it merged. While it +is possible to send patches directly to Linus Torvalds and have him merge +them, things are not normally done that way. Linus is busy, and there are +subsystem maintainers who watch over specific parts of the kernel. Usually +you will be wanting that maintainer to merge your patches. If there is no +obvious maintainer, Andrew Morton is often the patch target of last resort. + +Patches need good subject lines. The canonical format for a patch line is +something like: + + [PATCH nn/mm] subsys: one-line description of the patch + +where "nn" is the ordinal number of the patch, "mm" is the total number of +patches in the series, and "subsys" is the name of the affected subsystem. +Clearly, nn/mm can be omitted for a single, standalone patch. + +If you have a significant series of patches, it is customary to send an +introductory description as part zero. This convention is not universally +followed though; if you use it, remember that information in the +introduction does not make it into the kernel changelogs. So please ensure +that the patches, themselves, have complete changelog information. + +In general, the second and following parts of a multi-part patch should be +sent as a reply to the first part so that they all thread together at the +receiving end. Tools like git and quilt have commands to mail out a set of +patches with the proper threading. If you have a long series, though, and +are using git, please provide the --no-chain-reply-to option to avoid +creating exceptionally deep nesting. diff --git a/trunk/Documentation/development-process/6.Followthrough b/trunk/Documentation/development-process/6.Followthrough new file mode 100644 index 000000000000..a8fba3d83a85 --- /dev/null +++ b/trunk/Documentation/development-process/6.Followthrough @@ -0,0 +1,202 @@ +6: FOLLOWTHROUGH + +At this point, you have followed the guidelines given so far and, with the +addition of your own engineering skills, have posted a perfect series of +patches. One of the biggest mistakes that even experienced kernel +developers can make is to conclude that their work is now done. In truth, +posting patches indicates a transition into the next stage of the process, +with, possibly, quite a bit of work yet to be done. + +It is a rare patch which is so good at its first posting that there is no +room for improvement. The kernel development process recognizes this fact, +and, as a result, is heavily oriented toward the improvement of posted +code. You, as the author of that code, will be expected to work with the +kernel community to ensure that your code is up to the kernel's quality +standards. A failure to participate in this process is quite likely to +prevent the inclusion of your patches into the mainline. + + +6.1: WORKING WITH REVIEWERS + +A patch of any significance will result in a number of comments from other +developers as they review the code. Working with reviewers can be, for +many developers, the most intimidating part of the kernel development +process. Life can be made much easier, though, if you keep a few things in +mind: + + - If you have explained your patch well, reviewers will understand its + value and why you went to the trouble of writing it. But that value + will not keep them from asking a fundamental question: what will it be + like to maintain a kernel with this code in it five or ten years later? + Many of the changes you may be asked to make - from coding style tweaks + to substantial rewrites - come from the understanding that Linux will + still be around and under development a decade from now. + + - Code review is hard work, and it is a relatively thankless occupation; + people remember who wrote kernel code, but there is little lasting fame + for those who reviewed it. So reviewers can get grumpy, especially when + they see the same mistakes being made over and over again. If you get a + review which seems angry, insulting, or outright offensive, resist the + impulse to respond in kind. Code review is about the code, not about + the people, and code reviewers are not attacking you personally. + + - Similarly, code reviewers are not trying to promote their employers' + agendas at the expense of your own. Kernel developers often expect to + be working on the kernel years from now, but they understand that their + employer could change. They truly are, almost without exception, + working toward the creation of the best kernel they can; they are not + trying to create discomfort for their employers' competitors. + +What all of this comes down to is that, when reviewers send you comments, +you need to pay attention to the technical observations that they are +making. Do not let their form of expression or your own pride keep that +from happening. When you get review comments on a patch, take the time to +understand what the reviewer is trying to say. If possible, fix the things +that the reviewer is asking you to fix. And respond back to the reviewer: +thank them, and describe how you will answer their questions. + +Note that you do not have to agree with every change suggested by +reviewers. If you believe that the reviewer has misunderstood your code, +explain what is really going on. If you have a technical objection to a +suggested change, describe it and justify your solution to the problem. If +your explanations make sense, the reviewer will accept them. Should your +explanation not prove persuasive, though, especially if others start to +agree with the reviewer, take some time to think things over again. It can +be easy to become blinded by your own solution to a problem to the point +that you don't realize that something is fundamentally wrong or, perhaps, +you're not even solving the right problem. + +One fatal mistake is to ignore review comments in the hope that they will +go away. They will not go away. If you repost code without having +responded to the comments you got the time before, you're likely to find +that your patches go nowhere. + +Speaking of reposting code: please bear in mind that reviewers are not +going to remember all the details of the code you posted the last time +around. So it is always a good idea to remind reviewers of previously +raised issues and how you dealt with them; the patch changelog is a good +place for this kind of information. Reviewers should not have to search +through list archives to familiarize themselves with what was said last +time; if you help them get a running start, they will be in a better mood +when they revisit your code. + +What if you've tried to do everything right and things still aren't going +anywhere? Most technical disagreements can be resolved through discussion, +but there are times when somebody simply has to make a decision. If you +honestly believe that this decision is going against you wrongly, you can +always try appealing to a higher power. As of this writing, that higher +power tends to be Andrew Morton. Andrew has a great deal of respect in the +kernel development community; he can often unjam a situation which seems to +be hopelessly blocked. Appealing to Andrew should not be done lightly, +though, and not before all other alternatives have been explored. And bear +in mind, of course, that he may not agree with you either. + + +6.2: WHAT HAPPENS NEXT + +If a patch is considered to be a good thing to add to the kernel, and once +most of the review issues have been resolved, the next step is usually +entry into a subsystem maintainer's tree. How that works varies from one +subsystem to the next; each maintainer has his or her own way of doing +things. In particular, there may be more than one tree - one, perhaps, +dedicated to patches planned for the next merge window, and another for +longer-term work. + +For patches applying to areas for which there is no obvious subsystem tree +(memory management patches, for example), the default tree often ends up +being -mm. Patches which affect multiple subsystems can also end up going +through the -mm tree. + +Inclusion into a subsystem tree can bring a higher level of visibility to a +patch. Now other developers working with that tree will get the patch by +default. Subsystem trees typically feed into -mm and linux-next as well, +making their contents visible to the development community as a whole. At +this point, there's a good chance that you will get more comments from a +new set of reviewers; these comments need to be answered as in the previous +round. + +What may also happen at this point, depending on the nature of your patch, +is that conflicts with work being done by others turn up. In the worst +case, heavy patch conflicts can result in some work being put on the back +burner so that the remaining patches can be worked into shape and merged. +Other times, conflict resolution will involve working with the other +developers and, possibly, moving some patches between trees to ensure that +everything applies cleanly. This work can be a pain, but count your +blessings: before the advent of the linux-next tree, these conflicts often +only turned up during the merge window and had to be addressed in a hurry. +Now they can be resolved at leisure, before the merge window opens. + +Some day, if all goes well, you'll log on and see that your patch has been +merged into the mainline kernel. Congratulations! Once the celebration is +complete (and you have added yourself to the MAINTAINERS file), though, it +is worth remembering an important little fact: the job still is not done. +Merging into the mainline brings its own challenges. + +To begin with, the visibility of your patch has increased yet again. There +may be a new round of comments from developers who had not been aware of +the patch before. It may be tempting to ignore them, since there is no +longer any question of your code being merged. Resist that temptation, +though; you still need to be responsive to developers who have questions or +suggestions. + +More importantly, though: inclusion into the mainline puts your code into +the hands of a much larger group of testers. Even if you have contributed +a driver for hardware which is not yet available, you will be surprised by +how many people will build your code into their kernels. And, of course, +where there are testers, there will be bug reports. + +The worst sort of bug reports are regressions. If your patch causes a +regression, you'll find an uncomfortable number of eyes upon you; +regressions need to be fixed as soon as possible. If you are unwilling or +unable to fix the regression (and nobody else does it for you), your patch +will almost certainly be removed during the stabilization period. Beyond +negating all of the work you have done to get your patch into the mainline, +having a patch pulled as the result of a failure to fix a regression could +well make it harder for you to get work merged in the future. + +After any regressions have been dealt with, there may be other, ordinary +bugs to deal with. The stabilization period is your best opportunity to +fix these bugs and ensure that your code's debut in a mainline kernel +release is as solid as possible. So, please, answer bug reports, and fix +the problems if at all possible. That's what the stabilization period is +for; you can start creating cool new patches once any problems with the old +ones have been taken care of. + +And don't forget that there are other milestones which may also create bug +reports: the next mainline stable release, when prominent distributors pick +up a version of the kernel containing your patch, etc. Continuing to +respond to these reports is a matter of basic pride in your work. If that +is insufficient motivation, though, it's also worth considering that the +development community remembers developers who lose interest in their code +after it's merged. The next time you post a patch, they will be evaluating +it with the assumption that you will not be around to maintain it +afterward. + + +6.3: OTHER THINGS THAT CAN HAPPEN + +One day, you may open your mail client and see that somebody has mailed you +a patch to your code. That is one of the advantages of having your code +out there in the open, after all. If you agree with the patch, you can +either forward it on to the subsystem maintainer (be sure to include a +proper From: line so that the attribution is correct, and add a signoff of +your own), or send an Acked-by: response back and let the original poster +send it upward. + +If you disagree with the patch, send a polite response explaining why. If +possible, tell the author what changes need to be made to make the patch +acceptable to you. There is a certain resistance to merging patches which +are opposed by the author and maintainer of the code, but it only goes so +far. If you are seen as needlessly blocking good work, those patches will +eventually flow around you and get into the mainline anyway. In the Linux +kernel, nobody has absolute veto power over any code. Except maybe Linus. + +On very rare occasion, you may see something completely different: another +developer posts a different solution to your problem. At that point, +chances are that one of the two patches will not be merged, and "mine was +here first" is not considered to be a compelling technical argument. If +somebody else's patch displaces yours and gets into the mainline, there is +really only one way to respond: be pleased that your problem got solved and +get on with your work. Having one's work shoved aside in this manner can +be hurtful and discouraging, but the community will remember your reaction +long after they have forgotten whose patch actually got merged. diff --git a/trunk/Documentation/development-process/7.AdvancedTopics b/trunk/Documentation/development-process/7.AdvancedTopics new file mode 100644 index 000000000000..a2cf74093aa1 --- /dev/null +++ b/trunk/Documentation/development-process/7.AdvancedTopics @@ -0,0 +1,173 @@ +7: ADVANCED TOPICS + +At this point, hopefully, you have a handle on how the development process +works. There is still more to learn, however! This section will cover a +number of topics which can be helpful for developers wanting to become a +regular part of the Linux kernel development process. + +7.1: MANAGING PATCHES WITH GIT + +The use of distributed version control for the kernel began in early 2002, +when Linus first started playing with the proprietary BitKeeper +application. While BitKeeper was controversial, the approach to software +version management it embodied most certainly was not. Distributed version +control enabled an immediate acceleration of the kernel development +project. In current times, there are several free alternatives to +BitKeeper. For better or for worse, the kernel project has settled on git +as its tool of choice. + +Managing patches with git can make life much easier for the developer, +especially as the volume of those patches grows. Git also has its rough +edges and poses certain hazards; it is a young and powerful tool which is +still being civilized by its developers. This document will not attempt to +teach the reader how to use git; that would be sufficient material for a +long document in its own right. Instead, the focus here will be on how git +fits into the kernel development process in particular. Developers who +wish to come up to speed with git will find more information at: + + http://git.or.cz/ + + http://www.kernel.org/pub/software/scm/git/docs/user-manual.html + +and on various tutorials found on the web. + +The first order of business is to read the above sites and get a solid +understanding of how git works before trying to use it to make patches +available to others. A git-using developer should be able to obtain a copy +of the mainline repository, explore the revision history, commit changes to +the tree, use branches, etc. An understanding of git's tools for the +rewriting of history (such as rebase) is also useful. Git comes with its +own terminology and concepts; a new user of git should know about refs, +remote branches, the index, fast-forward merges, pushes and pulls, detached +heads, etc. It can all be a little intimidating at the outset, but the +concepts are not that hard to grasp with a bit of study. + +Using git to generate patches for submission by email can be a good +exercise while coming up to speed. + +When you are ready to start putting up git trees for others to look at, you +will, of course, need a server that can be pulled from. Setting up such a +server with git-daemon is relatively straightforward if you have a system +which is accessible to the Internet. Otherwise, free, public hosting sites +(Github, for example) are starting to appear on the net. Established +developers can get an account on kernel.org, but those are not easy to come +by; see http://kernel.org/faq/ for more information. + +The normal git workflow involves the use of a lot of branches. Each line +of development can be separated into a separate "topic branch" and +maintained independently. Branches in git are cheap, there is no reason to +not make free use of them. And, in any case, you should not do your +development in any branch which you intend to ask others to pull from. +Publicly-available branches should be created with care; merge in patches +from development branches when they are in complete form and ready to go - +not before. + +Git provides some powerful tools which can allow you to rewrite your +development history. An inconvenient patch (one which breaks bisection, +say, or which has some other sort of obvious bug) can be fixed in place or +made to disappear from the history entirely. A patch series can be +rewritten as if it had been written on top of today's mainline, even though +you have been working on it for months. Changes can be transparently +shifted from one branch to another. And so on. Judicious use of git's +ability to revise history can help in the creation of clean patch sets with +fewer problems. + +Excessive use of this capability can lead to other problems, though, beyond +a simple obsession for the creation of the perfect project history. +Rewriting history will rewrite the changes contained in that history, +turning a tested (hopefully) kernel tree into an untested one. But, beyond +that, developers cannot easily collaborate if they do not have a shared +view of the project history; if you rewrite history which other developers +have pulled into their repositories, you will make life much more difficult +for those developers. So a simple rule of thumb applies here: history +which has been exported to others should generally be seen as immutable +thereafter. + +So, once you push a set of changes to your publicly-available server, those +changes should not be rewritten. Git will attempt to enforce this rule if +you try to push changes which do not result in a fast-forward merge +(i.e. changes which do not share the same history). It is possible to +override this check, and there may be times when it is necessary to rewrite +an exported tree. Moving changesets between trees to avoid conflicts in +linux-next is one example. But such actions should be rare. This is one +of the reasons why development should be done in private branches (which +can be rewritten if necessary) and only moved into public branches when +it's in a reasonably advanced state. + +As the mainline (or other tree upon which a set of changes is based) +advances, it is tempting to merge with that tree to stay on the leading +edge. For a private branch, rebasing can be an easy way to keep up with +another tree, but rebasing is not an option once a tree is exported to the +world. Once that happens, a full merge must be done. Merging occasionally +makes good sense, but overly frequent merges can clutter the history +needlessly. Suggested technique in this case is to merge infrequently, and +generally only at specific release points (such as a mainline -rc +release). If you are nervous about specific changes, you can always +perform test merges in a private branch. The git "rerere" tool can be +useful in such situations; it remembers how merge conflicts were resolved +so that you don't have to do the same work twice. + +One of the biggest recurring complaints about tools like git is this: the +mass movement of patches from one repository to another makes it easy to +slip in ill-advised changes which go into the mainline below the review +radar. Kernel developers tend to get unhappy when they see that kind of +thing happening; putting up a git tree with unreviewed or off-topic patches +can affect your ability to get trees pulled in the future. Quoting Linus: + + You can send me patches, but for me to pull a git patch from you, I + need to know that you know what you're doing, and I need to be able + to trust things *without* then having to go and check every + individual change by hand. + +(http://lwn.net/Articles/224135/). + +To avoid this kind of situation, ensure that all patches within a given +branch stick closely to the associated topic; a "driver fixes" branch +should not be making changes to the core memory management code. And, most +importantly, do not use a git tree to bypass the review process. Post an +occasional summary of the tree to the relevant list, and, when the time is +right, request that the tree be included in linux-next. + +If and when others start to send patches for inclusion into your tree, +don't forget to review them. Also ensure that you maintain the correct +authorship information; the git "am" tool does its best in this regard, but +you may have to add a "From:" line to the patch if it has been relayed to +you via a third party. + +When requesting a pull, be sure to give all the relevant information: where +your tree is, what branch to pull, and what changes will result from the +pull. The git request-pull command can be helpful in this regard; it will +format the request as other developers expect, and will also check to be +sure that you have remembered to push those changes to the public server. + + +7.2: REVIEWING PATCHES + +Some readers will certainly object to putting this section with "advanced +topics" on the grounds that even beginning kernel developers should be +reviewing patches. It is certainly true that there is no better way to +learn how to program in the kernel environment than by looking at code +posted by others. In addition, reviewers are forever in short supply; by +looking at code you can make a significant contribution to the process as a +whole. + +Reviewing code can be an intimidating prospect, especially for a new kernel +developer who may well feel nervous about questioning code - in public - +which has been posted by those with more experience. Even code written by +the most experienced developers can be improved, though. Perhaps the best +piece of advice for reviewers (all reviewers) is this: phrase review +comments as questions rather than criticisms. Asking "how does the lock +get released in this path?" will always work better than stating "the +locking here is wrong." + +Different developers will review code from different points of view. Some +are mostly concerned with coding style and whether code lines have trailing +white space. Others will focus primarily on whether the change implemented +by the patch as a whole is a good thing for the kernel or not. Yet others +will check for problematic locking, excessive stack usage, possible +security issues, duplication of code found elsewhere, adequate +documentation, adverse effects on performance, user-space ABI changes, etc. +All types of review, if they lead to better code going into the kernel, are +welcome and worthwhile. + + diff --git a/trunk/Documentation/development-process/8.Conclusion b/trunk/Documentation/development-process/8.Conclusion new file mode 100644 index 000000000000..1990ab4b4949 --- /dev/null +++ b/trunk/Documentation/development-process/8.Conclusion @@ -0,0 +1,74 @@ +8: FOR MORE INFORMATION + +There are numerous sources of information on Linux kernel development and +related topics.

Hopefully it has provided a helpful understanding of how the +Linux kernel is developed and how you can participate in that process. + +In the end, it's the participation that matters. Any open source software +project is no more than the sum of what its contributors put into it. The +Linux kernel has progressed as quickly and as well as it has because it has +been helped by an impressively large group of developers, all of whom are +working to make it better. The kernel is a premier example of what can be +done when thousands of people work together toward a common goal. + +The kernel can always benefit from a larger developer base, though. There +is always more work to do. But, just as importantly, most other +participants in the Linux ecosystem can benefit through contributing to the +kernel. Getting code into the mainline is the key to higher code quality, +lower maintenance and distribution costs, a higher level of influence over +the direction of kernel development, and more. It is a situation where +everybody involved wins.

Using a file descriptor gives ioctl operations access to +autofs specific information stored in the super block. The operations +are things such as setting an autofs mount catatonic, setting the +expire timeout and requesting expire checks. As is explained below, +certain types of autofs triggered mounts can end up covering an autofs +mount itself which prevents us being able to use open(2) to obtain a +file descriptor for these operations if we don't already have one open. + +Currently autofs uses "umount -l" (lazy umount) to clear active mounts +at restart. While using lazy umount works for most cases, anything that +needs to walk back up the mount tree to construct a path, such as +getcwd(2) and the proc file system /proc//cwd, no longer works +because the point from which the path is constructed has been detached +from the mount tree. + +The actual problem with autofs is that it can't reconnect to existing +mounts. Immediately one thinks of just adding the ability to remount +autofs file systems would solve it, but alas, that can't work. This is +because autofs direct mounts and the implementation of "on demand mount +and expire" of nested mount trees have the file system mounted directly +on top of the mount trigger directory dentry. + +For example, there are two types of automount maps, direct (in the kernel +module source you will see a third type called an offset, which is just +a direct mount in disguise) and indirect. + +Here is a master map with direct and indirect map entries: + +/- /etc/auto.direct +/test /etc/auto.indirect + +and the corresponding map files: + +/etc/auto.direct: + +/automount/dparse/g6 budgie:/autofs/export1 +/automount/dparse/g1 shark:/autofs/export1 +and so on. + +/etc/auto.indirect: + +g1 shark:/autofs/export1 +g6 budgie:/autofs/export1 +and so on. + +For the above indirect map an autofs file system is mounted on /test and +mounts are triggered for each sub-directory key by the inode lookup +operation. So we see a mount of shark:/autofs/export1 on /test/g1, for +example. + +The way that direct mounts are handled is by making an autofs mount on +each full path, such as /automount/dparse/g1, and using it as a mount +trigger. So when we walk on the path we mount shark:/autofs/export1 "on +top of this mount point". Since these are always directories we can +use the follow_link inode operation to trigger the mount. + +But, each entry in direct and indirect maps can have offsets (making +them multi-mount map entries). + +For example, an indirect mount map entry could also be: + +g1 \ + / shark:/autofs/export5/testing/test \ + /s1 shark:/autofs/export/testing/test/s1 \ + /s2 shark:/autofs/export5/testing/test/s2 \ + /s1/ss1 shark:/autofs/export1 \ + /s2/ss2 shark:/autofs/export2 + +and a similarly a direct mount map entry could also be: + +/automount/dparse/g1 \ + / shark:/autofs/export5/testing/test \ + /s1 shark:/autofs/export/testing/test/s1 \ + /s2 shark:/autofs/export5/testing/test/s2 \ + /s1/ss1 shark:/autofs/export2 \ + /s2/ss2 shark:/autofs/export2 + +One of the issues with version 4 of autofs was that, when mounting an +entry with a large number of offsets, possibly with nesting, we needed +to mount and umount all of the offsets as a single unit. Not really a +problem, except for people with a large number of offsets in map entries. +This mechanism is used for the well known "hosts" map and we have seen +cases (in 2.4) where the available number of mounts are exhausted or +where the number of privileged ports available is exhausted. + +In version 5 we mount only as we go down the tree of offsets and +similarly for expiring them which resolves the above problem. There is +somewhat more detail to the implementation but it isn't needed for the +sake of the problem explanation. The one important detail is that these +offsets are implemented using the same mechanism as the direct mounts +above and so the mount points can be covered by a mount. + +The current autofs implementation uses an ioctl file descriptor opened +on the mount point for control operations. The references held by the +descriptor are accounted for in checks made to determine if a mount is +in use and is also used to access autofs file system information held +in the mount super block. So the use of a file handle needs to be +retained. + + +The Solution +============ + +To be able to restart autofs leaving existing direct, indirect and +offset mounts in place we need to be able to obtain a file handle +for these potentially covered autofs mount points. Rather than just +implement an isolated operation it was decided to re-implement the +existing ioctl interface and add new operations to provide this +functionality. + +In addition, to be able to reconstruct a mount tree that has busy mounts, +the uid and gid of the last user that triggered the mount needs to be +available because these can be used as macro substitution variables in +autofs maps. They are recorded at mount request time and an operation +has been added to retrieve them. + +Since we're re-implementing the control interface, a couple of other +problems with the existing interface have been addressed. First, when +a mount or expire operation completes a status is returned to the +kernel by either a "send ready" or a "send fail" operation. The +"send fail" operation of the ioctl interface could only ever send +ENOENT so the re-implementation allows user space to send an actual +status. Another expensive operation in user space, for those using +very large maps, is discovering if a mount is present. Usually this +involves scanning /proc/mounts and since it needs to be done quite +often it can introduce significant overhead when there are many entries +in the mount table. An operation to lookup the mount status of a mount +point dentry (covered or not) has also been added. + +Current kernel development policy recommends avoiding the use of the +ioctl mechanism in favor of systems such as Netlink. An implementation +using this system was attempted to evaluate its suitability and it was +found to be inadequate, in this case. The Generic Netlink system was +used for this as raw Netlink would lead to a significant increase in +complexity. There's no question that the Generic Netlink system is an +elegant solution for common case ioctl functions but it's not a complete +replacement probably because it's primary purpose in life is to be a +message bus implementation rather than specifically an ioctl replacement. +While it would be possible to work around this there is one concern +that lead to the decision to not use it. This is that the autofs +expire in the daemon has become far to complex because umount +candidates are enumerated, almost for no other reason than to "count" +the number of times to call the expire ioctl. This involves scanning +the mount table which has proved to be a big overhead for users with +large maps. The best way to improve this is try and get back to the +way the expire was done long ago. That is, when an expire request is +issued for a mount (file handle) we should continually call back to +the daemon until we can't umount any more mounts, then return the +appropriate status to the daemon. At the moment we just expire one +mount at a time. A Generic Netlink implementation would exclude this +possibility for future development due to the requirements of the +message bus architecture. + + +autofs4 Miscellaneous Device mount control interface +==================================================== + +The control interface is opening a device node, typically /dev/autofs. + +All the ioctls use a common structure to pass the needed parameter +information and return operation results: + +struct autofs_dev_ioctl { + __u32 ver_major; + __u32 ver_minor; + __u32 size; /* total size of data passed in + * including this struct */ + __s32 ioctlfd; /* automount command fd */ + + __u32 arg1; /* Command parameters */ + __u32 arg2; + + char path[0]; +}; + +The ioctlfd field is a mount point file descriptor of an autofs mount +point. It is returned by the open call and is used by all calls except +the check for whether a given path is a mount point, where it may +optionally be used to check a specific mount corresponding to a given +mount point file descriptor, and when requesting the uid and gid of the +last successful mount on a directory within the autofs file system. + +The fields arg1 and arg2 are used to communicate parameters and results of +calls made as described below. + +The path field is used to pass a path where it is needed and the size field +is used account for the increased structure length when translating the +structure sent from user space. + +This structure can be initialized before setting specific fields by using +the void function call init_autofs_dev_ioctl(struct autofs_dev_ioctl *). + +All of the ioctls perform a copy of this structure from user space to +kernel space and return -EINVAL if the size parameter is smaller than +the structure size itself, -ENOMEM if the kernel memory allocation fails +or -EFAULT if the copy itself fails. Other checks include a version check +of the compiled in user space version against the module version and a +mismatch results in a -EINVAL return. If the size field is greater than +the structure size then a path is assumed to be present and is checked to +ensure it begins with a "/" and is NULL terminated, otherwise -EINVAL is +returned. Following these checks, for all ioctl commands except +AUTOFS_DEV_IOCTL_VERSION_CMD, AUTOFS_DEV_IOCTL_OPENMOUNT_CMD and +AUTOFS_DEV_IOCTL_CLOSEMOUNT_CMD the ioctlfd is validated and if it is +not a valid descriptor or doesn't correspond to an autofs mount point +an error of -EBADF, -ENOTTY or -EINVAL (not an autofs descriptor) is +returned. + + +The ioctls +========== + +An example of an implementation which uses this interface can be seen +in autofs version 5.0.4 and later in file lib/dev-ioctl-lib.c of the +distribution tar available for download from kernel.org in directory +/pub/linux/daemons/autofs/v5. + +The device node ioctl operations implemented by this interface are: + + +AUTOFS_DEV_IOCTL_VERSION +------------------------ + +Get the major and minor version of the autofs4 device ioctl kernel module +implementation. It requires an initialized struct autofs_dev_ioctl as an +input parameter and sets the version information in the passed in structure. +It returns 0 on success or the error -EINVAL if a version mismatch is +detected. + + +AUTOFS_DEV_IOCTL_PROTOVER_CMD and AUTOFS_DEV_IOCTL_PROTOSUBVER_CMD +------------------------------------------------------------------ + +Get the major and minor version of the autofs4 protocol version understood +by loaded module. This call requires an initialized struct autofs_dev_ioctl +with the ioctlfd field set to a valid autofs mount point descriptor +and sets the requested version number in structure field arg1. These +commands return 0 on success or one of the negative error codes if +validation fails. + + +AUTOFS_DEV_IOCTL_OPENMOUNT and AUTOFS_DEV_IOCTL_CLOSEMOUNT +---------------------------------------------------------- + +Obtain and release a file descriptor for an autofs managed mount point +path. The open call requires an initialized struct autofs_dev_ioctl with +the the path field set and the size field adjusted appropriately as well +as the arg1 field set to the device number of the autofs mount. The +device number can be obtained from the mount options shown in +/proc/mounts. The close call requires an initialized struct +autofs_dev_ioct with the ioctlfd field set to the descriptor obtained +from the open call. The release of the file descriptor can also be done +with close(2) so any open descriptors will also be closed at process exit. +The close call is included in the implemented operations largely for +completeness and to provide for a consistent user space implementation. + + +AUTOFS_DEV_IOCTL_READY_CMD and AUTOFS_DEV_IOCTL_FAIL_CMD +-------------------------------------------------------- + +Return mount and expire result status from user space to the kernel. +Both of these calls require an initialized struct autofs_dev_ioctl +with the ioctlfd field set to the descriptor obtained from the open +call and the arg1 field set to the wait queue token number, received +by user space in the foregoing mount or expire request. The arg2 field +is set to the status to be returned. For the ready call this is always +0 and for the fail call it is set to the errno of the operation. + + +AUTOFS_DEV_IOCTL_SETPIPEFD_CMD +------------------------------ + +Set the pipe file descriptor used for kernel communication to the daemon. +Normally this is set at mount time using an option but when reconnecting +to a existing mount we need to use this to tell the autofs mount about +the new kernel pipe descriptor. In order to protect mounts against +incorrectly setting the pipe descriptor we also require that the autofs +mount be catatonic (see next call). + +The call requires an initialized struct autofs_dev_ioctl with the +ioctlfd field set to the descriptor obtained from the open call and +the arg1 field set to descriptor of the pipe. On success the call +also sets the process group id used to identify the controlling process +(eg. the owning automount(8) daemon) to the process group of the caller. + + +AUTOFS_DEV_IOCTL_CATATONIC_CMD +------------------------------ + +Make the autofs mount point catatonic. The autofs mount will no longer +issue mount requests, the kernel communication pipe descriptor is released +and any remaining waits in the queue released. + +The call requires an initialized struct autofs_dev_ioctl with the +ioctlfd field set to the descriptor obtained from the open call. + + +AUTOFS_DEV_IOCTL_TIMEOUT_CMD +---------------------------- + +Set the expire timeout for mounts withing an autofs mount point. + +The call requires an initialized struct autofs_dev_ioctl with the +ioctlfd field set to the descriptor obtained from the open call. + + +AUTOFS_DEV_IOCTL_REQUESTER_CMD +------------------------------ + +Return the uid and gid of the last process to successfully trigger a the +mount on the given path dentry. + +The call requires an initialized struct autofs_dev_ioctl with the path +field set to the mount point in question and the size field adjusted +appropriately as well as the arg1 field set to the device number of the +containing autofs mount. Upon return the struct field arg1 contains the +uid and arg2 the gid. + +When reconstructing an autofs mount tree with active mounts we need to +re-connect to mounts that may have used the original process uid and +gid (or string variations of them) for mount lookups within the map entry. +This call provides the ability to obtain this uid and gid so they may be +used by user space for the mount map lookups. + + +AUTOFS_DEV_IOCTL_EXPIRE_CMD +--------------------------- + +Issue an expire request to the kernel for an autofs mount. Typically +this ioctl is called until no further expire candidates are found. + +The call requires an initialized struct autofs_dev_ioctl with the +ioctlfd field set to the descriptor obtained from the open call. In +addition an immediate expire, independent of the mount timeout, can be +requested by setting the arg1 field to 1. If no expire candidates can +be found the ioctl returns -1 with errno set to EAGAIN. + +This call causes the kernel module to check the mount corresponding +to the given ioctlfd for mounts that can be expired, issues an expire +request back to the daemon and waits for completion. + +AUTOFS_DEV_IOCTL_ASKUMOUNT_CMD +------------------------------ + +Checks if an autofs mount point is in use. + +The call requires an initialized struct autofs_dev_ioctl with the +ioctlfd field set to the descriptor obtained from the open call and +it returns the result in the arg1 field, 1 for busy and 0 otherwise. + + +AUTOFS_DEV_IOCTL_ISMOUNTPOINT_CMD +--------------------------------- + +Check if the given path is a mountpoint. + +The call requires an initialized struct autofs_dev_ioctl. There are two +possible variations. Both use the path field set to the path of the mount +point to check and the size field adjusted appropriately. One uses the +ioctlfd field to identify a specific mount point to check while the other +variation uses the path and optionaly arg1 set to an autofs mount type. +The call returns 1 if this is a mount point and sets arg1 to the device +number of the mount and field arg2 to the relevant super block magic +number (described below) or 0 if it isn't a mountpoint. In both cases +the the device number (as returned by new_encode_dev()) is returned +in field arg1. + +If supplied with a file descriptor we're looking for a specific mount, +not necessarily at the top of the mounted stack. In this case the path +the descriptor corresponds to is considered a mountpoint if it is itself +a mountpoint or contains a mount, such as a multi-mount without a root +mount. In this case we return 1 if the descriptor corresponds to a mount +point and and also returns the super magic of the covering mount if there +is one or 0 if it isn't a mountpoint. + +If a path is supplied (and the ioctlfd field is set to -1) then the path +is looked up and is checked to see if it is the root of a mount. If a +type is also given we are looking for a particular autofs mount and if +a match isn't found a fail is returned. If the the located path is the +root of a mount 1 is returned along with the super magic of the mount +or 0 otherwise. + diff --git a/trunk/Documentation/filesystems/ext3.txt b/trunk/Documentation/filesystems/ext3.txt index b45f3c1b8b43..9dd2a3bb2acc 100644 --- a/trunk/Documentation/filesystems/ext3.txt +++ b/trunk/Documentation/filesystems/ext3.txt @@ -96,6 +96,11 @@ errors=remount-ro(*) Remount the filesystem read-only on an error. errors=continue Keep going on a filesystem error. errors=panic Panic and halt the machine if an error occurs. +data_err=ignore(*) Just print an error message if an error occurs + in a file data buffer in ordered mode. +data_err=abort Abort the journal if an error occurs in a file + data buffer in ordered mode. + grpid Give objects the same group ID as their creator. bsdgroups @@ -193,6 +198,5 @@ kernel source: programs: http://e2fsprogs.sourceforge.net/ http://ext2resize.sourceforge.net -useful links: http://www.zip.com.au/~akpm/linux/ext3/ext3-usage.html - http://www-106.ibm.com/developerworks/linux/library/l-fs7/ +useful links: http://www-106.ibm.com/developerworks/linux/library/l-fs7/ http://www-106.ibm.com/developerworks/linux/library/l-fs8/ diff --git a/trunk/Documentation/filesystems/ext4.txt b/trunk/Documentation/filesystems/ext4.txt index eb154ef36c2a..174eaff7ded9 100644 --- a/trunk/Documentation/filesystems/ext4.txt +++ b/trunk/Documentation/filesystems/ext4.txt @@ -2,19 +2,24 @@ Ext4 Filesystem =============== -This is a development version of the ext4 filesystem, an advanced level -of the ext3 filesystem which incorporates scalability and reliability -enhancements for supporting large filesystems (64 bit) in keeping with -increasing disk capacities and state-of-the-art feature requirements. +Ext4 is an an advanced level of the ext3 filesystem which incorporates +scalability and reliability enhancements for supporting large filesystems +(64 bit) in keeping with increasing disk capacities and state-of-the-art +feature requirements. -Mailing list: linux-ext4@vger.kernel.org +Mailing list: linux-ext4@vger.kernel.org +Web site: http://ext4.wiki.kernel.org 1.

I also tried on an eeePC (Celeron, clocked at 900 Mhz). Interesting +observation was that this one is only 30% slower (according to time) +executing the code as my 3Ghz D920 processor. + +Well, it was expected not to be easy so maybe instead move to a +different track: let's move back to the code from attempt2 and do some +loop unrolling. This will eliminate a few if statements. I'll try +different amounts of unrolling to see what works best. + + +Attempt 4 +========= + +Unrolled the loop 1, 2, 3 and 4 times. +For 4 the code starts with: + + for (i = 0; i < 4; i++) + { + cur = *bp++; + par ^= cur; + rp4 ^= cur; + rp6 ^= cur; + rp8 ^= cur; + rp10 ^= cur; + if (i & 0x1) rp13 ^= cur; else rp12 ^= cur; + if (i & 0x2) rp15 ^= cur; else rp14 ^= cur; + cur = *bp++; + par ^= cur; + rp5 ^= cur; + rp6 ^= cur; + ... + + +Analysis 4 +========== + +Unrolling once gains about 15% +Unrolling twice keeps the gain at about 15% +Unrolling three times gives a gain of 30% compared to attempt 2. +Unrolling four times gives a marginal improvement compared to unrolling +three times. + +I decided to proceed with a four time unrolled loop anyway. It was my gut +feeling that in the next steps I would obtain additional gain from it. + +The next step was triggered by the fact that par contains the xor of all +bytes and rp4 and rp5 each contain the xor of half of the bytes. +So in effect par = rp4 ^ rp5. But as xor is commutative we can also say +that rp5 = par ^ rp4. So no need to keep both rp4 and rp5 around. We can +eliminate rp5 (or rp4, but I already foresaw another optimisation). +The same holds for rp6/7, rp8/9, rp10/11 rp12/13 and rp14/15. + + +Attempt 5 +========= + +Effectively so all odd digit rp assignments in the loop were removed. +This included the else clause of the if statements. +Of course after the loop we need to correct things by adding code like: + rp5 = par ^ rp4; +Also the initial assignments (rp5 = 0; etc) could be removed. +Along the line I also removed the initialisation of rp0/1/2/3. + + +Analysis 5 +========== + +Measurements showed this was a good move. The run-time roughly halved +compared with attempt 4 with 4 times unrolled, and we only require 1/3rd +of the processor time compared to the current code in the linux kernel. + +However, still I thought there was more. I didn't like all the if +statements. Why not keep a running parity and only keep the last if +statement. Time for yet another version! + + +Attempt 6 +========= + +THe code within the for loop was changed to: + + for (i = 0; i < 4; i++) + { + cur = *bp++; tmppar = cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= tmppar; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; rp8 ^= tmppar; + + cur = *bp++; tmppar ^= cur; rp4 ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; rp10 ^= tmppar; + + cur = *bp++; tmppar ^= cur; rp4 ^= cur; rp6 ^= cur; rp8 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= cur; rp8 ^= cur; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; rp8 ^= cur; + cur = *bp++; tmppar ^= cur; rp8 ^= cur; + + cur = *bp++; tmppar ^= cur; rp4 ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; + + par ^= tmppar; + if ((i & 0x1) == 0) rp12 ^= tmppar; + if ((i & 0x2) == 0) rp14 ^= tmppar; + } + +As you can see tmppar is used to accumulate the parity within a for +iteration. In the last 3 statements is is added to par and, if needed, +to rp12 and rp14. + +While making the changes I also found that I could exploit that tmppar +contains the running parity for this iteration. So instead of having: +rp4 ^= cur; rp6 = cur; +I removed the rp6 = cur; statement and did rp6 ^= tmppar; on next +statement. A similar change was done for rp8 and rp10 + + +Analysis 6 +========== + +Measuring this code again showed big gain. When executing the original +linux code 1 million times, this took about 1 second on my system. +(using time to measure the performance). After this iteration I was back +to 0.075 sec. Actually I had to decide to start measuring over 10 +million interations in order not to loose too much accuracy. This one +definitely seemed to be the jackpot! + +There is a little bit more room for improvement though. There are three +places with statements: +rp4 ^= cur; rp6 ^= cur; +It seems more efficient to also maintain a variable rp4_6 in the while +loop; This eliminates 3 statements per loop. Of course after the loop we +need to correct by adding: + rp4 ^= rp4_6; + rp6 ^= rp4_6 +Furthermore there are 4 sequential assingments to rp8. This can be +encoded slightly more efficient by saving tmppar before those 4 lines +and later do rp8 = rp8 ^ tmppar ^ notrp8; +(where notrp8 is the value of rp8 before those 4 lines). +Again a use of the commutative property of xor. +Time for a new test! + + +Attempt 7 +========= + +The new code now looks like: + + for (i = 0; i < 4; i++) + { + cur = *bp++; tmppar = cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= tmppar; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; rp8 ^= tmppar; + + cur = *bp++; tmppar ^= cur; rp4_6 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; rp10 ^= tmppar; + + notrp8 = tmppar; + cur = *bp++; tmppar ^= cur; rp4_6 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; + rp8 = rp8 ^ tmppar ^ notrp8; + + cur = *bp++; tmppar ^= cur; rp4_6 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; + + par ^= tmppar; + if ((i & 0x1) == 0) rp12 ^= tmppar; + if ((i & 0x2) == 0) rp14 ^= tmppar; + } + rp4 ^= rp4_6; + rp6 ^= rp4_6; + + +Not a big change, but every penny counts :-) + + +Analysis 7 +========== + +Acutally this made things worse. Not very much, but I don't want to move +into the wrong direction. Maybe something to investigate later. Could +have to do with caching again. + +Guess that is what there is to win within the loop. Maybe unrolling one +more time will help. I'll keep the optimisations from 7 for now. + + +Attempt 8 +========= + +Unrolled the loop one more time. + + +Analysis 8 +========== + +This makes things worse. Let's stick with attempt 6 and continue from there. +Although it seems that the code within the loop cannot be optimised +further there is still room to optimize the generation of the ecc codes. +We can simply calcualate the total parity. If this is 0 then rp4 = rp5 +etc. If the parity is 1, then rp4 = !rp5; +But if rp4 = rp5 we do not need rp5 etc. We can just write the even bits +in the result byte and then do something like + code[0] |= (code[0] << 1); +Lets test this. + + +Attempt 9 +========= + +Changed the code but again this slightly degrades performance. Tried all +kind of other things, like having dedicated parity arrays to avoid the +shift after parity[rp7] << 7; No gain. +Change the lookup using the parity array by using shift operators (e.g. +replace parity[rp7] << 7 with: +rp7 ^= (rp7 << 4); +rp7 ^= (rp7 << 2); +rp7 ^= (rp7 << 1); +rp7 &= 0x80; +No gain. + +The only marginal change was inverting the parity bits, so we can remove +the last three invert statements. + +Ah well, pity this does not deliver more. Then again 10 million +iterations using the linux driver code takes between 13 and 13.5 +seconds, whereas my code now takes about 0.73 seconds for those 10 +million iterations. So basically I've improved the performance by a +factor 18 on my system. Not that bad. Of course on different hardware +you will get different results. No warranties! + +But of course there is no such thing as a free lunch. The codesize almost +tripled (from 562 bytes to 1434 bytes). Then again, it is not that much. + + +Correcting errors +================= + +For correcting errors I again used the ST application note as a starter, +but I also peeked at the existing code. +The algorithm itself is pretty straightforward. Just xor the given and +the calculated ecc. If all bytes are 0 there is no problem. If 11 bits +are 1 we have one correctable bit error. If there is 1 bit 1, we have an +error in the given ecc code. +It proved to be fastest to do some table lookups. Performance gain +introduced by this is about a factor 2 on my system when a repair had to +be done, and 1% or so if no repair had to be done. +Code size increased from 330 bytes to 686 bytes for this function. +(gcc 4.2, -O3) + + +Conclusion +========== + +The gain when calculating the ecc is tremendous. Om my development hardware +a speedup of a factor of 18 for ecc calculation was achieved. On a test on an +embedded system with a MIPS core a factor 7 was obtained. +On a test with a Linksys NSLU2 (ARMv5TE processor) the speedup was a factor +5 (big endian mode, gcc 4.1.2, -O3) +For correction not much gain could be obtained (as bitflips are rare). Then +again there are also much less cycles spent there. + +It seems there is not much more gain possible in this, at least when +programmed in C. Of course it might be possible to squeeze something more +out of it with an assembler program, but due to pipeline behaviour etc +this is very tricky (at least for intel hw). + +Author: Frans Meulenbroeks +Copyright (C) 2008 Koninklijke Philips Electronics NV. diff --git a/trunk/Documentation/networking/cs89x0.txt b/trunk/Documentation/networking/cs89x0.txt index 6387d3decf85..c725d33b316f 100644 --- a/trunk/Documentation/networking/cs89x0.txt +++ b/trunk/Documentation/networking/cs89x0.txt @@ -3,7 +3,7 @@ NOTE ---- This document was contributed by Cirrus Logic for kernel 2.2.5.

Glossary + + + Introduction + +UWB is a wide-band communication protocol that is to serve also as the +low-level protocol for others (much like TCP sits on IP). Currently +these others are Wireless USB and TCP/IP, but seems Bluetooth and +Firewire/1394 are coming along. + +UWB uses a band from roughly 3 to 10 GHz, transmitting at a max of +~-41dB (or 0.074 uW/MHz--geography specific data is still being +negotiated w/ regulators, so watch for changes). That band is divided in +a bunch of ~1.5 GHz wide channels (or band groups) composed of three +subbands/subchannels (528 MHz each). Each channel is independent of each +other, so you could consider them different "busses". Initially this +driver considers them all a single one. + +Radio time is divided in 65536 us long /superframes/, each one divided +in 256 256us long /MASs/ (Media Allocation Slots), which are the basic +time/media allocation units for transferring data. At the beginning of +each superframe there is a Beacon Period (BP), where every device +transmit its beacon on a single MAS. The length of the BP depends on how +many devices are present and the length of their beacons. + +Devices have a MAC (fixed, 48 bit address) and a device (changeable, 16 +bit address) and send periodic beacons to advertise themselves and pass +info on what they are and do. They advertise their capabilities and a +bunch of other stuff. + +The different logical parts of this driver are: + + * + + *UWB*: the Ultra-Wide-Band stack -- manages the radio and + associated spectrum to allow for devices sharing it. Allows to + control bandwidth assingment, beaconing, scanning, etc + + * + + *WUSB*: the layer that sits on top of UWB to provide Wireless USB. + The Wireless USB spec defines means to control a UWB radio and to + do the actual WUSB. + + + HWA: Host Wire adapters, your Wireless USB dongle + +WUSB also defines a device called a Host Wire Adaptor (HWA), which in +mere terms is a USB dongle that enables your PC to have UWB and Wireless +USB. The Wireless USB Host Controller in a HWA looks to the host like a +[Wireless] USB controller connected via USB (!) + +The HWA itself is broken in two or three main interfaces: + + * + + *RC*: Radio control -- this implements an interface to the + Ultra-Wide-Band radio controller. The driver for this implements a + USB-based UWB Radio Controller to the UWB stack. + + * + + *HC*: the wireless USB host controller. It looks like a USB host + whose root port is the radio and the WUSB devices connect to it. + To the system it looks like a separate USB host. The driver (will) + implement a USB host controller (similar to UHCI, OHCI or EHCI) + for which the root hub is the radio...To reiterate: it is a USB + controller that is connected via USB instead of PCI. + + * + + *WINET*: some HW provide a WiNET interface (IP over UWB). This + package provides a driver for it (it looks like a network + interface, winetX). The driver detects when there is a link up for + their type and kick into gear. + + + DWA: Device Wired Adaptor, a Wireless USB hub for wired devices + +These are the complement to HWAs. They are a USB host for connecting +wired devices, but it is connected to your PC connected via Wireless +USB. To the system it looks like yet another USB host. To the untrained +eye, it looks like a hub that connects upstream wirelessly. + +We still offer no support for this; however, it should share a lot of +code with the HWA-RC driver; there is a bunch of factorization work that +has been done to support that in upcoming releases. + + + WHCI: Wireless Host Controller Interface, the PCI WUSB host adapter + +This is your usual PCI device that implements WHCI. Similar in concept +to EHCI, it allows your wireless USB devices (including DWAs) to connect +to your host via a PCI interface. As in the case of the HWA, it has a +Radio Control interface and the WUSB Host Controller interface per se. + +There is still no driver support for this, but will be in upcoming +releases. + + + The UWB stack + +The main mission of the UWB stack is to keep a tally of which devices +are in radio proximity to allow drivers to connect to them. As well, it +provides an API for controlling the local radio controllers (RCs from +now on), such as to start/stop beaconing, scan, allocate bandwidth, etc. + + + Devices and hosts: the basic structure + +The main building block here is the UWB device (struct uwb_dev). For +each device that pops up in radio presence (ie: the UWB host receives a +beacon from it) you get a struct uwb_dev that will show up in +/sys/class/uwb and in /sys/bus/uwb/devices. + +For each RC that is detected, a new struct uwb_rc is created. In turn, a +RC is also a device, so they also show in /sys/class/uwb and +/sys/bus/uwb/devices, but at the same time, only radio controllers show +up in /sys/class/uwb_rc. + + * + + [*] The reason for RCs being also devices is that not only we can + see them while enumerating the system device tree, but also on the + radio (their beacons and stuff), so the handling has to be + likewise to that of a device. + +Each RC driver is implemented by a separate driver that plugs into the +interface that the UWB stack provides through a struct uwb_rc_ops. The +spec creators have been nice enough to make the message format the same +for HWA and WHCI RCs, so the driver is really a very thin transport that +moves the requests from the UWB API to the device [/uwb_rc_ops->cmd()/] +and sends the replies and notifications back to the API +[/uwb_rc_neh_grok()/]. Notifications are handled to the UWB daemon, that +is chartered, among other things, to keep the tab of how the UWB radio +neighborhood looks, creating and destroying devices as they show up or +dissapear. + +Command execution is very simple: a command block is sent and a event +block or reply is expected back. For sending/receiving command/events, a +handle called /neh/ (Notification/Event Handle) is opened with +/uwb_rc_neh_open()/. + +The HWA-RC (USB dongle) driver (drivers/uwb/hwa-rc.c) does this job for +the USB connected HWA. Eventually, drivers/whci-rc.c will do the same +for the PCI connected WHCI controller. + + + Host Controller life cycle + +So let's say we connect a dongle to the system: it is detected and +firmware uploaded if needed [for Intel's i1480 +/drivers/uwb/ptc/usb.c:ptc_usb_probe()/] and then it is reenumerated. +Now we have a real HWA device connected and +/drivers/uwb/hwa-rc.c:hwarc_probe()/ picks it up, that will set up the +Wire-Adaptor environment and then suck it into the UWB stack's vision of +the world [/drivers/uwb/lc-rc.c:uwb_rc_add()/]. + + * + + [*] The stack should put a new RC to scan for devices + [/uwb_rc_scan()/] so it finds what's available around and tries to + connect to them, but this is policy stuff and should be driven + from user space. As of now, the operator is expected to do it + manually; see the release notes for documentation on the procedure. + +When a dongle is disconnected, /drivers/uwb/hwa-rc.c:hwarc_disconnect()/ +takes time of tearing everything down safely (or not...). + + + On the air: beacons and enumerating the radio neighborhood + +So assuming we have devices and we have agreed for a channel to connect +on (let's say 9), we put the new RC to beacon: + + * + + $ echo 9 0 > /sys/class/uwb_rc/uwb0/beacon + +Now it is visible. If there were other devices in the same radio channel +and beacon group (that's what the zero is for), the dongle's radio +control interface will send beacon notifications on its +notification/event endpoint (NEEP). The beacon notifications are part of +the event stream that is funneled into the API with +/drivers/uwb/neh.c:uwb_rc_neh_grok()/ and delivered to the UWBD, the UWB +daemon through a notification list. + +UWBD wakes up and scans the event list; finds a beacon and adds it to +the BEACON CACHE (/uwb_beca/). If he receives a number of beacons from +the same device, he considers it to be 'onair' and creates a new device +[/drivers/uwb/lc-dev.c:uwbd_dev_onair()/]. Similarly, when no beacons +are received in some time, the device is considered gone and wiped out +[uwbd calls periodically /uwb/beacon.c:uwb_beca_purge()/ that will purge +the beacon cache of dead devices]. + + + Device lists + +All UWB devices are kept in the list of the struct bus_type uwb_bus. + + + Bandwidth allocation + +The UWB stack maintains a local copy of DRP availability through +processing of incoming *DRP Availability Change* notifications. This +local copy is currently used to present the current bandwidth +availability to the user through the sysfs file +/sys/class/uwb_rc/uwbx/bw_avail. In the future the bandwidth +availability information will be used by the bandwidth reservation +routines. + +The bandwidth reservation routines are in progress and are thus not +present in the current release. When completed they will enable a user +to initiate DRP reservation requests through interaction with sysfs. DRP +reservation requests from remote UWB devices will also be handled. The +bandwidth management done by the UWB stack will include callbacks to the +higher layers will enable the higher layers to use the reservations upon +completion. [Note: The bandwidth reservation work is in progress and +subject to change.] + + + Wireless USB Host Controller drivers + +*WARNING* This section needs a lot of work! + +As explained above, there are three different types of HCs in the WUSB +world: HWA-HC, DWA-HC and WHCI-HC. + +HWA-HC and DWA-HC share that they are Wire-Adapters (USB or WUSB +connected controllers), and their transfer management system is almost +identical. So is their notification delivery system. + +HWA-HC and WHCI-HC share that they are both WUSB host controllers, so +they have to deal with WUSB device life cycle and maintenance, wireless +root-hub + +HWA exposes a Host Controller interface (HWA-HC 0xe0/02/02). This has +three endpoints (Notifications, Data Transfer In and Data Transfer +Out--known as NEP, DTI and DTO in the code). + +We reserve UWB bandwidth for our Wireless USB Cluster, create a Cluster +ID and tell the HC to use all that. Then we start it. This means the HC +starts sending MMCs. + + * + + The MMCs are blocks of data defined somewhere in the WUSB1.0 spec + that define a stream in the UWB channel time allocated for sending + WUSB IEs (host to device commands/notifications) and Device + Notifications (device initiated to host). Each host defines a + unique Wireless USB cluster through MMCs. Devices can connect to a + single cluster at the time. The IEs are Information Elements, and + among them are the bandwidth allocations that tell each device + when can they transmit or receive. + +Now it all depends on external stimuli. + +*New device connection* + +A new device pops up, it scans the radio looking for MMCs that give out +the existence of Wireless USB channels. Once one (or more) are found, +selects which one to connect to. Sends a /DN_Connect/ (device +notification connect) during the DNTS (Device Notification Time +Slot--announced in the MMCs + +HC picks the /DN_Connect/ out (nep module sends to notif.c for delivery +into /devconnect/). This process starts the authentication process for +the device. First we allocate a /fake port/ and assign an +unauthenticated address (128 to 255--what we really do is +0x80 | fake_port_idx). We fiddle with the fake port status and /khubd/ +sees a new connection, so he moves on to enable the fake port with a reset. + +So now we are in the reset path -- we know we have a non-yet enumerated +device with an unauthorized address; we ask user space to authenticate +(FIXME: not yet done, similar to bluetooth pairing), then we do the key +exchange (FIXME: not yet done) and issue a /set address 0/ to bring the +device to the default state. Device is authenticated. + +From here, the USB stack takes control through the usb_hcd ops. khubd +has seen the port status changes, as we have been toggling them. It will +start enumerating and doing transfers through usb_hcd->urb_enqueue() to +read descriptors and move our data. + +*Device life cycle and keep alives* + +Everytime there is a succesful transfer to/from a device, we update a +per-device activity timestamp. If not, every now and then we check and +if the activity timestamp gets old, we ping the device by sending it a +Keep Alive IE; it responds with a /DN_Alive/ pong during the DNTS (this +arrives to us as a notification through +devconnect.c:wusb_handle_dn_alive(). If a device times out, we +disconnect it from the system (cleaning up internal information and +toggling the bits in the fake hub port, which kicks khubd into removing +the rest of the stuff). + +This is done through devconnect:__wusb_check_devs(), which will scan the +device list looking for whom needs refreshing. + +If the device wants to disconnect, it will either die (ugly) or send a +/DN_Disconnect/ that will prompt a disconnection from the system. + +*Sending and receiving data* + +Data is sent and received through /Remote Pipes/ (rpipes). An rpipe is +/aimed/ at an endpoint in a WUSB device. This is the same for HWAs and +DWAs. + +Each HC has a number of rpipes and buffers that can be assigned to them; +when doing a data transfer (xfer), first the rpipe has to be aimed and +prepared (buffers assigned), then we can start queueing requests for +data in or out. + +Data buffers have to be segmented out before sending--so we send first a +header (segment request) and then if there is any data, a data buffer +immediately after to the DTI interface (yep, even the request). If our +buffer is bigger than the max segment size, then we just do multiple +requests. + +[This sucks, because doing USB scatter gatter in Linux is resource +intensive, if any...not that the current approach is not. It just has to +be cleaned up a lot :)]. + +If reading, we don't send data buffers, just the segment headers saying +we want to read segments. + +When the xfer is executed, we receive a notification that says data is +ready in the DTI endpoint (handled through +xfer.c:wa_handle_notif_xfer()). In there we read from the DTI endpoint a +descriptor that gives us the status of the transfer, its identification +(given when we issued it) and the segment number. If it was a data read, +we issue another URB to read into the destination buffer the chunk of +data coming out of the remote endpoint. Done, wait for the next guy.

The document attempts to provide the overall +rationale behind this mechanism and the rationale for some of the design +decisions that drove the implementation. The latter design rationale is +discussed in the context of an implementation description. Admittedly, one +can obtain the implementation details--the "what does it do?"--by reading the +code. One hopes that the descriptions below add value by provide the answer +to "why does it do that?". + +Unevictable LRU Infrastructure: + +The Unevictable LRU adds an additional LRU list to track unevictable pages +and to hide these pages from vmscan. This mechanism is based on a patch by +Larry Woodman of Red Hat to address several scalability problems with page +reclaim in Linux. The problems have been observed at customer sites on large +memory x86_64 systems. For example, a non-numal x86_64 platform with 128GB +of main memory will have over 32 million 4k pages in a single zone. When a +large fraction of these pages are not evictable for any reason [see below], +vmscan will spend a lot of time scanning the LRU lists looking for the small +fraction of pages that are evictable. This can result in a situation where +all cpus are spending 100% of their time in vmscan for hours or days on end, +with the system completely unresponsive. + +The Unevictable LRU infrastructure addresses the following classes of +unevictable pages: + ++ page owned by ramfs ++ page mapped into SHM_LOCKed shared memory regions ++ page mapped into VM_LOCKED [mlock()ed] vmas + +The infrastructure might be able to handle other conditions that make pages +unevictable, either by definition or by circumstance, in the future. + + +The Unevictable LRU List + +The Unevictable LRU infrastructure consists of an additional, per-zone, LRU list +called the "unevictable" list and an associated page flag, PG_unevictable, to +indicate that the page is being managed on the unevictable list. The +PG_unevictable flag is analogous to, and mutually exclusive with, the PG_active +flag in that it indicates on which LRU list a page resides when PG_lru is set. +The unevictable LRU list is source configurable based on the UNEVICTABLE_LRU +Kconfig option. + +The Unevictable LRU infrastructure maintains unevictable pages on an additional +LRU list for a few reasons: + +1) We get to "treat unevictable pages just like we treat other pages in the + system, which means we get to use the same code to manipulate them, the + same code to isolate them (for migrate, etc.), the same code to keep track + of the statistics, etc..." [Rik van Riel] + +2) We want to be able to migrate unevictable pages between nodes--for memory + defragmentation, workload management and memory hotplug. The linux kernel + can only migrate pages that it can successfully isolate from the lru lists. + If we were to maintain pages elsewise than on an lru-like list, where they + can be found by isolate_lru_page(), we would prevent their migration, unless + we reworked migration code to find the unevictable pages. + + +The unevictable LRU list does not differentiate between file backed and swap +backed [anon] pages. This differentiation is only important while the pages +are, in fact, evictable. + +The unevictable LRU list benefits from the "arrayification" of the per-zone +LRU lists and statistics originally proposed and posted by Christoph Lameter. + +The unevictable list does not use the lru pagevec mechanism. Rather, +unevictable pages are placed directly on the page's zone's unevictable +list under the zone lru_lock. The reason for this is to prevent stranding +of pages on the unevictable list when one task has the page isolated from the +lru and other tasks are changing the "evictability" state of the page. + + +Unevictable LRU and Memory Controller Interaction + +The memory controller data structure automatically gets a per zone unevictable +lru list as a result of the "arrayification" of the per-zone LRU lists. The +memory controller tracks the movement of pages to and from the unevictable list. +When a memory control group comes under memory pressure, the controller will +not attempt to reclaim pages on the unevictable list. This has a couple of +effects. Because the pages are "hidden" from reclaim on the unevictable list, +the reclaim process can be more efficient, dealing only with pages that have +a chance of being reclaimed. On the other hand, if too many of the pages +charged to the control group are unevictable, the evictable portion of the +working set of the tasks in the control group may not fit into the available +memory. This can cause the control group to thrash or to oom-kill tasks. + + +Unevictable LRU: Detecting Unevictable Pages + +The function page_evictable(page, vma) in vmscan.c determines whether a +page is evictable or not. For ramfs pages and pages in SHM_LOCKed regions, +page_evictable() tests a new address space flag, AS_UNEVICTABLE, in the page's +address space using a wrapper function. Wrapper functions are used to set, +clear and test the flag to reduce the requirement for #ifdef's throughout the +source code. AS_UNEVICTABLE is set on ramfs inode/mapping when it is created. +This flag remains for the life of the inode. + +For shared memory regions, AS_UNEVICTABLE is set when an application +successfully SHM_LOCKs the region and is removed when the region is +SHM_UNLOCKed. Note that shmctl(SHM_LOCK, ...) does not populate the page +tables for the region as does, for example, mlock(). So, we make no special +effort to push any pages in the SHM_LOCKed region to the unevictable list. +Vmscan will do this when/if it encounters the pages during reclaim. On +SHM_UNLOCK, shmctl() scans the pages in the region and "rescues" them from the +unevictable list if no other condition keeps them unevictable. If a SHM_LOCKed +region is destroyed, the pages are also "rescued" from the unevictable list in +the process of freeing them. + +page_evictable() detects mlock()ed pages by testing an additional page flag, +PG_mlocked via the PageMlocked() wrapper. If the page is NOT mlocked, and a +non-NULL vma is supplied, page_evictable() will check whether the vma is +VM_LOCKED via is_mlocked_vma(). is_mlocked_vma() will SetPageMlocked() and +update the appropriate statistics if the vma is VM_LOCKED. This method allows +efficient "culling" of pages in the fault path that are being faulted in to +VM_LOCKED vmas. + + +Unevictable Pages and Vmscan [shrink_*_list()] + +If unevictable pages are culled in the fault path, or moved to the unevictable +list at mlock() or mmap() time, vmscan will never encounter the pages until +they have become evictable again, for example, via munlock() and have been +"rescued" from the unevictable list. However, there may be situations where we +decide, for the sake of expediency, to leave a unevictable page on one of the +regular active/inactive LRU lists for vmscan to deal with. Vmscan checks for +such pages in all of the shrink_{active|inactive|page}_list() functions and +will "cull" such pages that it encounters--that is, it diverts those pages to +the unevictable list for the zone being scanned. + +There may be situations where a page is mapped into a VM_LOCKED vma, but the +page is not marked as PageMlocked. Such pages will make it all the way to +shrink_page_list() where they will be detected when vmscan walks the reverse +map in try_to_unmap(). If try_to_unmap() returns SWAP_MLOCK, shrink_page_list() +will cull the page at that point. + +Note that for anonymous pages, shrink_page_list() attempts to add the page to +the swap cache before it tries to unmap the page. To avoid this unnecessary +consumption of swap space, shrink_page_list() calls try_to_munlock() to check +whether any VM_LOCKED vmas map the page without attempting to unmap the page. +If try_to_munlock() returns SWAP_MLOCK, shrink_page_list() will cull the page +without consuming swap space. try_to_munlock() will be described below. + +To "cull" an unevictable page, vmscan simply puts the page back on the lru +list using putback_lru_page()--the inverse operation to isolate_lru_page()-- +after dropping the page lock. Because the condition which makes the page +unevictable may change once the page is unlocked, putback_lru_page() will +recheck the unevictable state of a page that it places on the unevictable lru +list. If the page has become unevictable, putback_lru_page() removes it from +the list and retries, including the page_unevictable() test. Because such a +race is a rare event and movement of pages onto the unevictable list should be +rare, these extra evictabilty checks should not occur in the majority of calls +to putback_lru_page(). + + +Mlocked Page: Prior Work + +The "Unevictable Mlocked Pages" infrastructure is based on work originally +posted by Nick Piggin in an RFC patch entitled "mm: mlocked pages off LRU". +Nick posted his patch as an alternative to a patch posted by Christoph +Lameter to achieve the same objective--hiding mlocked pages from vmscan. +In Nick's patch, he used one of the struct page lru list link fields as a count +of VM_LOCKED vmas that map the page. This use of the link field for a count +prevented the management of the pages on an LRU list. Thus, mlocked pages were +not migratable as isolate_lru_page() could not find them and the lru list link +field was not available to the migration subsystem. Nick resolved this by +putting mlocked pages back on the lru list before attempting to isolate them, +thus abandoning the count of VM_LOCKED vmas. When Nick's patch was integrated +with the Unevictable LRU work, the count was replaced by walking the reverse +map to determine whether any VM_LOCKED vmas mapped the page. More on this +below. + + +Mlocked Pages: Basic Management + +Mlocked pages--pages mapped into a VM_LOCKED vma--represent one class of +unevictable pages. When such a page has been "noticed" by the memory +management subsystem, the page is marked with the PG_mlocked [PageMlocked()] +flag. A PageMlocked() page will be placed on the unevictable LRU list when +it is added to the LRU. Pages can be "noticed" by memory management in +several places: + +1) in the mlock()/mlockall() system call handlers. +2) in the mmap() system call handler when mmap()ing a region with the + MAP_LOCKED flag, or mmap()ing a region in a task that has called + mlockall() with the MCL_FUTURE flag. Both of these conditions result + in the VM_LOCKED flag being set for the vma. +3) in the fault path, if mlocked pages are "culled" in the fault path, + and when a VM_LOCKED stack segment is expanded. +4) as mentioned above, in vmscan:shrink_page_list() with attempting to + reclaim a page in a VM_LOCKED vma--via try_to_unmap() or try_to_munlock(). + +Mlocked pages become unlocked and rescued from the unevictable list when: + +1) mapped in a range unlocked via the munlock()/munlockall() system calls. +2) munmapped() out of the last VM_LOCKED vma that maps the page, including + unmapping at task exit. +3) when the page is truncated from the last VM_LOCKED vma of an mmap()ed file. +4) before a page is COWed in a VM_LOCKED vma. + + +Mlocked Pages: mlock()/mlockall() System Call Handling + +Both [do_]mlock() and [do_]mlockall() system call handlers call mlock_fixup() +for each vma in the range specified by the call. In the case of mlockall(), +this is the entire active address space of the task. Note that mlock_fixup() +is used for both mlock()ing and munlock()ing a range of memory. A call to +mlock() an already VM_LOCKED vma, or to munlock() a vma that is not VM_LOCKED +is treated as a no-op--mlock_fixup() simply returns. + +If the vma passes some filtering described in "Mlocked Pages: Filtering Vmas" +below, mlock_fixup() will attempt to merge the vma with its neighbors or split +off a subset of the vma if the range does not cover the entire vma. Once the +vma has been merged or split or neither, mlock_fixup() will call +__mlock_vma_pages_range() to fault in the pages via get_user_pages() and +to mark the pages as mlocked via mlock_vma_page(). + +Note that the vma being mlocked might be mapped with PROT_NONE. In this case, +get_user_pages() will be unable to fault in the pages. That's OK. If pages +do end up getting faulted into this VM_LOCKED vma, we'll handle them in the +fault path or in vmscan. + +Also note that a page returned by get_user_pages() could be truncated or +migrated out from under us, while we're trying to mlock it. To detect +this, __mlock_vma_pages_range() tests the page_mapping after acquiring +the page lock. If the page is still associated with its mapping, we'll +go ahead and call mlock_vma_page(). If the mapping is gone, we just +unlock the page and move on. Worse case, this results in page mapped +in a VM_LOCKED vma remaining on a normal LRU list without being +PageMlocked(). Again, vmscan will detect and cull such pages. + +mlock_vma_page(), called with the page locked [N.B., not "mlocked"], will +TestSetPageMlocked() for each page returned by get_user_pages(). We use +TestSetPageMlocked() because the page might already be mlocked by another +task/vma and we don't want to do extra work. We especially do not want to +count an mlocked page more than once in the statistics. If the page was +already mlocked, mlock_vma_page() is done. + +If the page was NOT already mlocked, mlock_vma_page() attempts to isolate the +page from the LRU, as it is likely on the appropriate active or inactive list +at that time. If the isolate_lru_page() succeeds, mlock_vma_page() will +putback the page--putback_lru_page()--which will notice that the page is now +mlocked and divert the page to the zone's unevictable LRU list. If +mlock_vma_page() is unable to isolate the page from the LRU, vmscan will handle +it later if/when it attempts to reclaim the page. + + +Mlocked Pages: Filtering Special Vmas + +mlock_fixup() filters several classes of "special" vmas: + +1) vmas with VM_IO|VM_PFNMAP set are skipped entirely. The pages behind + these mappings are inherently pinned, so we don't need to mark them as + mlocked. In any case, most of the pages have no struct page in which to + so mark the page. Because of this, get_user_pages() will fail for these + vmas, so there is no sense in attempting to visit them. + +2) vmas mapping hugetlbfs page are already effectively pinned into memory. + We don't need nor want to mlock() these pages. However, to preserve the + prior behavior of mlock()--before the unevictable/mlock changes--mlock_fixup() + will call make_pages_present() in the hugetlbfs vma range to allocate the + huge pages and populate the ptes. + +3) vmas with VM_DONTEXPAND|VM_RESERVED are generally user space mappings of + kernel pages, such as the vdso page, relay channel pages, etc. These pages + are inherently unevictable and are not managed on the LRU lists. + mlock_fixup() treats these vmas the same as hugetlbfs vmas. It calls + make_pages_present() to populate the ptes. + +Note that for all of these special vmas, mlock_fixup() does not set the +VM_LOCKED flag. Therefore, we won't have to deal with them later during +munlock() or munmap()--for example, at task exit. Neither does mlock_fixup() +account these vmas against the task's "locked_vm". + +Mlocked Pages: Downgrading the Mmap Semaphore. + +mlock_fixup() must be called with the mmap semaphore held for write, because +it may have to merge or split vmas. However, mlocking a large region of +memory can take a long time--especially if vmscan must reclaim pages to +satisfy the regions requirements. Faulting in a large region with the mmap +semaphore held for write can hold off other faults on the address space, in +the case of a multi-threaded task. It can also hold off scans of the task's +address space via /proc. While testing under heavy load, it was observed that +the ps(1) command could be held off for many minutes while a large segment was +mlock()ed down. + +To address this issue, and to make the system more responsive during mlock()ing +of large segments, mlock_fixup() downgrades the mmap semaphore to read mode +during the call to __mlock_vma_pages_range(). This works fine. However, the +callers of mlock_fixup() expect the semaphore to be returned in write mode. +So, mlock_fixup() "upgrades" the semphore to write mode. Linux does not +support an atomic upgrade_sem() call, so mlock_fixup() must drop the semaphore +and reacquire it in write mode. In a multi-threaded task, it is possible for +the task memory map to change while the semaphore is dropped. Therefore, +mlock_fixup() looks up the vma at the range start address after reacquiring +the semaphore in write mode and verifies that it still covers the original +range. If not, mlock_fixup() returns an error [-EAGAIN]. All callers of +mlock_fixup() have been changed to deal with this new error condition. + +Note: when munlocking a region, all of the pages should already be resident-- +unless we have racing threads mlocking() and munlocking() regions. So, +unlocking should not have to wait for page allocations nor faults of any kind. +Therefore mlock_fixup() does not downgrade the semaphore for munlock(). + + +Mlocked Pages: munlock()/munlockall() System Call Handling + +The munlock() and munlockall() system calls are handled by the same functions-- +do_mlock[all]()--as the mlock() and mlockall() system calls with the unlock +vs lock operation indicated by an argument. So, these system calls are also +handled by mlock_fixup(). Again, if called for an already munlock()ed vma, +mlock_fixup() simply returns. Because of the vma filtering discussed above, +VM_LOCKED will not be set in any "special" vmas. So, these vmas will be +ignored for munlock. + +If the vma is VM_LOCKED, mlock_fixup() again attempts to merge or split off +the specified range. The range is then munlocked via the function +__mlock_vma_pages_range()--the same function used to mlock a vma range-- +passing a flag to indicate that munlock() is being performed. + +Because the vma access protections could have been changed to PROT_NONE after +faulting in and mlocking some pages, get_user_pages() was unreliable for visiting +these pages for munlocking. Because we don't want to leave pages mlocked(), +get_user_pages() was enhanced to accept a flag to ignore the permissions when +fetching the pages--all of which should be resident as a result of previous +mlock()ing. + +For munlock(), __mlock_vma_pages_range() unlocks individual pages by calling +munlock_vma_page(). munlock_vma_page() unconditionally clears the PG_mlocked +flag using TestClearPageMlocked(). As with mlock_vma_page(), munlock_vma_page() +use the Test*PageMlocked() function to handle the case where the page might +have already been unlocked by another task. If the page was mlocked, +munlock_vma_page() updates that zone statistics for the number of mlocked +pages. Note, however, that at this point we haven't checked whether the page +is mapped by other VM_LOCKED vmas. + +We can't call try_to_munlock(), the function that walks the reverse map to check +for other VM_LOCKED vmas, without first isolating the page from the LRU. +try_to_munlock() is a variant of try_to_unmap() and thus requires that the page +not be on an lru list. [More on these below.] However, the call to +isolate_lru_page() could fail, in which case we couldn't try_to_munlock(). +So, we go ahead and clear PG_mlocked up front, as this might be the only chance +we have. If we can successfully isolate the page, we go ahead and +try_to_munlock(), which will restore the PG_mlocked flag and update the zone +page statistics if it finds another vma holding the page mlocked. If we fail +to isolate the page, we'll have left a potentially mlocked page on the LRU. +This is fine, because we'll catch it later when/if vmscan tries to reclaim the +page. This should be relatively rare. + +Mlocked Pages: Migrating Them... + +A page that is being migrated has been isolated from the lru lists and is +held locked across unmapping of the page, updating the page's mapping +[address_space] entry and copying the contents and state, until the +page table entry has been replaced with an entry that refers to the new +page. Linux supports migration of mlocked pages and other unevictable +pages. This involves simply moving the PageMlocked and PageUnevictable states +from the old page to the new page. + +Note that page migration can race with mlocking or munlocking of the same +page. This has been discussed from the mlock/munlock perspective in the +respective sections above. Both processes [migration, m[un]locking], hold +the page locked. This provides the first level of synchronization. Page +migration zeros out the page_mapping of the old page before unlocking it, +so m[un]lock can skip these pages by testing the page mapping under page +lock. + +When completing page migration, we place the new and old pages back onto the +lru after dropping the page lock. The "unneeded" page--old page on success, +new page on failure--will be freed when the reference count held by the +migration process is released. To ensure that we don't strand pages on the +unevictable list because of a race between munlock and migration, page +migration uses the putback_lru_page() function to add migrated pages back to +the lru. + + +Mlocked Pages: mmap(MAP_LOCKED) System Call Handling + +In addition the the mlock()/mlockall() system calls, an application can request +that a region of memory be mlocked using the MAP_LOCKED flag with the mmap() +call. Furthermore, any mmap() call or brk() call that expands the heap by a +task that has previously called mlockall() with the MCL_FUTURE flag will result +in the newly mapped memory being mlocked. Before the unevictable/mlock changes, +the kernel simply called make_pages_present() to allocate pages and populate +the page table. + +To mlock a range of memory under the unevictable/mlock infrastructure, the +mmap() handler and task address space expansion functions call +mlock_vma_pages_range() specifying the vma and the address range to mlock. +mlock_vma_pages_range() filters vmas like mlock_fixup(), as described above in +"Mlocked Pages: Filtering Vmas". It will clear the VM_LOCKED flag, which will +have already been set by the caller, in filtered vmas. Thus these vma's need +not be visited for munlock when the region is unmapped. + +For "normal" vmas, mlock_vma_pages_range() calls __mlock_vma_pages_range() to +fault/allocate the pages and mlock them. Again, like mlock_fixup(), +mlock_vma_pages_range() downgrades the mmap semaphore to read mode before +attempting to fault/allocate and mlock the pages; and "upgrades" the semaphore +back to write mode before returning. + +The callers of mlock_vma_pages_range() will have already added the memory +range to be mlocked to the task's "locked_vm". To account for filtered vmas, +mlock_vma_pages_range() returns the number of pages NOT mlocked. All of the +callers then subtract a non-negative return value from the task's locked_vm. +A negative return value represent an error--for example, from get_user_pages() +attempting to fault in a vma with PROT_NONE access. In this case, we leave +the memory range accounted as locked_vm, as the protections could be changed +later and pages allocated into that region. + + +Mlocked Pages: munmap()/exit()/exec() System Call Handling + +When unmapping an mlocked region of memory, whether by an explicit call to +munmap() or via an internal unmap from exit() or exec() processing, we must +munlock the pages if we're removing the last VM_LOCKED vma that maps the pages. +Before the unevictable/mlock changes, mlocking did not mark the pages in any way, +so unmapping them required no processing. + +To munlock a range of memory under the unevictable/mlock infrastructure, the +munmap() hander and task address space tear down function call +munlock_vma_pages_all(). The name reflects the observation that one always +specifies the entire vma range when munlock()ing during unmap of a region. +Because of the vma filtering when mlocking() regions, only "normal" vmas that +actually contain mlocked pages will be passed to munlock_vma_pages_all(). + +munlock_vma_pages_all() clears the VM_LOCKED vma flag and, like mlock_fixup() +for the munlock case, calls __munlock_vma_pages_range() to walk the page table +for the vma's memory range and munlock_vma_page() each resident page mapped by +the vma. This effectively munlocks the page, only if this is the last +VM_LOCKED vma that maps the page. + + +Mlocked Page: try_to_unmap() + +[Note: the code changes represented by this section are really quite small +compared to the text to describe what happening and why, and to discuss the +implications.] + +Pages can, of course, be mapped into multiple vmas. Some of these vmas may +have VM_LOCKED flag set. It is possible for a page mapped into one or more +VM_LOCKED vmas not to have the PG_mlocked flag set and therefore reside on one +of the active or inactive LRU lists. This could happen if, for example, a +task in the process of munlock()ing the page could not isolate the page from +the LRU. As a result, vmscan/shrink_page_list() might encounter such a page +as described in "Unevictable Pages and Vmscan [shrink_*_list()]". To +handle this situation, try_to_unmap() has been enhanced to check for VM_LOCKED +vmas while it is walking a page's reverse map. + +try_to_unmap() is always called, by either vmscan for reclaim or for page +migration, with the argument page locked and isolated from the LRU. BUG_ON() +assertions enforce this requirement. Separate functions handle anonymous and +mapped file pages, as these types of pages have different reverse map +mechanisms. + + try_to_unmap_anon() + +To unmap anonymous pages, each vma in the list anchored in the anon_vma must be +visited--at least until a VM_LOCKED vma is encountered. If the page is being +unmapped for migration, VM_LOCKED vmas do not stop the process because mlocked +pages are migratable. However, for reclaim, if the page is mapped into a +VM_LOCKED vma, the scan stops. try_to_unmap() attempts to acquire the mmap +semphore of the mm_struct to which the vma belongs in read mode. If this is +successful, try_to_unmap() will mlock the page via mlock_vma_page()--we +wouldn't have gotten to try_to_unmap() if the page were already mlocked--and +will return SWAP_MLOCK, indicating that the page is unevictable. If the +mmap semaphore cannot be acquired, we are not sure whether the page is really +unevictable or not. In this case, try_to_unmap() will return SWAP_AGAIN. + + try_to_unmap_file() -- linear mappings + +Unmapping of a mapped file page works the same, except that the scan visits +all vmas that maps the page's index/page offset in the page's mapping's +reverse map priority search tree. It must also visit each vma in the page's +mapping's non-linear list, if the list is non-empty. As for anonymous pages, +on encountering a VM_LOCKED vma for a mapped file page, try_to_unmap() will +attempt to acquire the associated mm_struct's mmap semaphore to mlock the page, +returning SWAP_MLOCK if this is successful, and SWAP_AGAIN, if not. + + try_to_unmap_file() -- non-linear mappings + +If a page's mapping contains a non-empty non-linear mapping vma list, then +try_to_un{map|lock}() must also visit each vma in that list to determine +whether the page is mapped in a VM_LOCKED vma. Again, the scan must visit +all vmas in the non-linear list to ensure that the pages is not/should not be +mlocked. If a VM_LOCKED vma is found in the list, the scan could terminate. +However, there is no easy way to determine whether the page is actually mapped +in a given vma--either for unmapping or testing whether the VM_LOCKED vma +actually pins the page. + +So, try_to_unmap_file() handles non-linear mappings by scanning a certain +number of pages--a "cluster"--in each non-linear vma associated with the page's +mapping, for each file mapped page that vmscan tries to unmap. If this happens +to unmap the page we're trying to unmap, try_to_unmap() will notice this on +return--(page_mapcount(page) == 0)--and return SWAP_SUCCESS. Otherwise, it +will return SWAP_AGAIN, causing vmscan to recirculate this page. We take +advantage of the cluster scan in try_to_unmap_cluster() as follows: + +For each non-linear vma, try_to_unmap_cluster() attempts to acquire the mmap +semaphore of the associated mm_struct for read without blocking. If this +attempt is successful and the vma is VM_LOCKED, try_to_unmap_cluster() will +retain the mmap semaphore for the scan; otherwise it drops it here. Then, +for each page in the cluster, if we're holding the mmap semaphore for a locked +vma, try_to_unmap_cluster() calls mlock_vma_page() to mlock the page. This +call is a no-op if the page is already locked, but will mlock any pages in +the non-linear mapping that happen to be unlocked. If one of the pages so +mlocked is the page passed in to try_to_unmap(), try_to_unmap_cluster() will +return SWAP_MLOCK, rather than the default SWAP_AGAIN. This will allow vmscan +to cull the page, rather than recirculating it on the inactive list. Again, +if try_to_unmap_cluster() cannot acquire the vma's mmap sem, it returns +SWAP_AGAIN, indicating that the page is mapped by a VM_LOCKED vma, but +couldn't be mlocked. + + +Mlocked pages: try_to_munlock() Reverse Map Scan + +TODO/FIXME: a better name might be page_mlocked()--analogous to the +page_referenced() reverse map walker--especially if we continue to call this +from shrink_page_list(). See related TODO/FIXME below. + +When munlock_vma_page()--see "Mlocked Pages: munlock()/munlockall() System +Call Handling" above--tries to munlock a page, or when shrink_page_list() +encounters an anonymous page that is not yet in the swap cache, they need to +determine whether or not the page is mapped by any VM_LOCKED vma, without +actually attempting to unmap all ptes from the page. For this purpose, the +unevictable/mlock infrastructure introduced a variant of try_to_unmap() called +try_to_munlock(). + +try_to_munlock() calls the same functions as try_to_unmap() for anonymous and +mapped file pages with an additional argument specifing unlock versus unmap +processing. Again, these functions walk the respective reverse maps looking +for VM_LOCKED vmas. When such a vma is found for anonymous pages and file +pages mapped in linear VMAs, as in the try_to_unmap() case, the functions +attempt to acquire the associated mmap semphore, mlock the page via +mlock_vma_page() and return SWAP_MLOCK. This effectively undoes the +pre-clearing of the page's PG_mlocked done by munlock_vma_page() and informs +shrink_page_list() that the anonymous page should be culled rather than added +to the swap cache in preparation for a try_to_unmap() that will almost +certainly fail. + +If try_to_unmap() is unable to acquire a VM_LOCKED vma's associated mmap +semaphore, it will return SWAP_AGAIN. This will allow shrink_page_list() +to recycle the page on the inactive list and hope that it has better luck +with the page next time. + +For file pages mapped into non-linear vmas, the try_to_munlock() logic works +slightly differently. On encountering a VM_LOCKED non-linear vma that might +map the page, try_to_munlock() returns SWAP_AGAIN without actually mlocking +the page. munlock_vma_page() will just leave the page unlocked and let +vmscan deal with it--the usual fallback position. + +Note that try_to_munlock()'s reverse map walk must visit every vma in a pages' +reverse map to determine that a page is NOT mapped into any VM_LOCKED vma. +However, the scan can terminate when it encounters a VM_LOCKED vma and can +successfully acquire the vma's mmap semphore for read and mlock the page. +Although try_to_munlock() can be called many [very many!] times when +munlock()ing a large region or tearing down a large address space that has been +mlocked via mlockall(), overall this is a fairly rare event. In addition, +although shrink_page_list() calls try_to_munlock() for every anonymous page that +it handles that is not yet in the swap cache, on average anonymous pages will +have very short reverse map lists. + +Mlocked Page: Page Reclaim in shrink_*_list() + +shrink_active_list() culls any obviously unevictable pages--i.e., +!page_evictable(page, NULL)--diverting these to the unevictable lru +list. However, shrink_active_list() only sees unevictable pages that +made it onto the active/inactive lru lists. Note that these pages do not +have PageUnevictable set--otherwise, they would be on the unevictable list and +shrink_active_list would never see them. + +Some examples of these unevictable pages on the LRU lists are: + +1) ramfs pages that have been placed on the lru lists when first allocated. + +2) SHM_LOCKed shared memory pages. shmctl(SHM_LOCK) does not attempt to + allocate or fault in the pages in the shared memory region. This happens + when an application accesses the page the first time after SHM_LOCKing + the segment. + +3) Mlocked pages that could not be isolated from the lru and moved to the + unevictable list in mlock_vma_page(). + +3) Pages mapped into multiple VM_LOCKED vmas, but try_to_munlock() couldn't + acquire the vma's mmap semaphore to test the flags and set PageMlocked. + munlock_vma_page() was forced to let the page back on to the normal + LRU list for vmscan to handle. + +shrink_inactive_list() also culls any unevictable pages that it finds +on the inactive lists, again diverting them to the appropriate zone's unevictable +lru list. shrink_inactive_list() should only see SHM_LOCKed pages that became +SHM_LOCKed after shrink_active_list() had moved them to the inactive list, or +pages mapped into VM_LOCKED vmas that munlock_vma_page() couldn't isolate from +the lru to recheck via try_to_munlock(). shrink_inactive_list() won't notice +the latter, but will pass on to shrink_page_list(). + +shrink_page_list() again culls obviously unevictable pages that it could +encounter for similar reason to shrink_inactive_list(). As already discussed, +shrink_page_list() proactively looks for anonymous pages that should have +PG_mlocked set but don't--these would not be detected by page_evictable()--to +avoid adding them to the swap cache unnecessarily. File pages mapped into +VM_LOCKED vmas but without PG_mlocked set will make it all the way to +try_to_unmap(). shrink_page_list() will divert them to the unevictable list when +try_to_unmap() returns SWAP_MLOCK, as discussed above. + +TODO/FIXME: If we can enhance the swap cache to reliably remove entries +with page_count(page) > 2, as long as all ptes are mapped to the page and +not the swap entry, we can probably remove the call to try_to_munlock() in +shrink_page_list() and just remove the page from the swap cache when +try_to_unmap() returns SWAP_MLOCK.
