Intro + -------- + +devres came up while trying to convert libata to use iomap. Each +iomapped address should be kept and unmapped on driver detach. For +example, a plain SFF ATA controller (that is, good old PCI IDE) in +native mode makes use of 5 PCI BARs and all of them should be +maintained. + +As with many other device drivers, libata low level drivers have +sufficient bugs in ->remove and ->probe failure path. Well, yes, +that's probably because libata low level driver developers are lazy +bunch, but aren't all low level driver developers? After spending a +day fiddling with braindamaged hardware with no document or +braindamaged document, if it's finally working, well, it's working. + +For one reason or another, low level drivers don't receive as much +attention or testing as core code, and bugs on driver detach or +initilaization failure doesn't happen often enough to be noticeable. +Init failure path is worse because it's much less travelled while +needs to handle multiple entry points. + +So, many low level drivers end up leaking resources on driver detach +and having half broken failure path implementation in ->probe() which +would leak resources or even cause oops when failure occurs. iomap +adds more to this mix. So do msi and msix. + + + 2. Devres + --------- + +devres is basically linked list of arbitrarily sized memory areas +associated with a struct device. Each devres entry is associated with +a release function. A devres can be released in several ways. No +matter what, all devres entries are released on driver detach. On +release, the associated release function is invoked and then the +devres entry is freed. + +Managed interface is created for resources commonly used by device +drivers using devres. For example, coherent DMA memory is acquired +using dma_alloc_coherent(). The managed version is called +dmam_alloc_coherent(). It is identical to dma_alloc_coherent() except +for the DMA memory allocated using it is managed and will be +automatically released on driver detach. Implementation looks like +the following. + + struct dma_devres { + size_t size; + void *vaddr; + dma_addr_t dma_handle; + }; + + static void dmam_coherent_release(struct device *dev, void *res) + { + struct dma_devres *this = res; + + dma_free_coherent(dev, this->size, this->vaddr, this->dma_handle); + } + + dmam_alloc_coherent(dev, size, dma_handle, gfp) + { + struct dma_devres *dr; + void *vaddr; + + dr = devres_alloc(dmam_coherent_release, sizeof(*dr), gfp); + ... + + /* alloc DMA memory as usual */ + vaddr = dma_alloc_coherent(...); + ... + + /* record size, vaddr, dma_handle in dr */ + dr->vaddr = vaddr; + ... + + devres_add(dev, dr); + + return vaddr; + } + +If a driver uses dmam_alloc_coherent(), the area is guaranteed to be +freed whether initialization fails half-way or the device gets +detached. If most resources are acquired using managed interface, a +driver can have much simpler init and exit code. Init path basically +looks like the following. + + my_init_one() + { + struct mydev *d; + + d = devm_kzalloc(dev, sizeof(*d), GFP_KERNEL); + if (!d) + return -ENOMEM; + + d->ring = dmam_alloc_coherent(...); + if (!d->ring) + return -ENOMEM; + + if (check something) + return -EINVAL; + ... + + return register_to_upper_layer(d); + } + +And exit path, + + my_remove_one() + { + unregister_from_upper_layer(d); + shutdown_my_hardware(); + } + +As shown above, low level drivers can be simplified a lot by using +devres. Complexity is shifted from less maintained low level drivers +to better maintained higher layer. Also, as init failure path is +shared with exit path, both can get more testing. + + + 3. Devres group + --------------- + +Devres entries can be grouped using devres group. When a group is +released, all contained normal devres entries and properly nested +groups are released. One usage is to rollback series of acquired +resources on failure. For example, + + if (!devres_open_group(dev, NULL, GFP_KERNEL)) + return -ENOMEM; + + acquire A; + if (failed) + goto err; + + acquire B; + if (failed) + goto err; + ... + + devres_remove_group(dev, NULL); + return 0; + + err: + devres_release_group(dev, NULL); + return err_code; + +As resource acquision failure usually means probe failure, constructs +like above are usually useful in midlayer driver (e.g. libata core +layer) where interface function shouldn't have side effect on failure. +For LLDs, just returning error code suffices in most cases. + +Each group is identified by void *id. It can either be explicitly +specified by @id argument to devres_open_group() or automatically +created by passing NULL as @id as in the above example. In both +cases, devres_open_group() returns the group's id. The returned id +can be passed to other devres functions to select the target group. +If NULL is given to those functions, the latest open group is +selected. + +For example, you can do something like the following. + + int my_midlayer_create_something() + { + if (!devres_open_group(dev, my_midlayer_create_something, GFP_KERNEL)) + return -ENOMEM; + + ... + + devres_close_group(dev, my_midlayer_something); + return 0; + } + + void my_midlayer_destroy_something() + { + devres_release_group(dev, my_midlayer_create_soemthing); + } + + + 4. Details + ---------- + +Lifetime of a devres entry begins on devres allocation and finishes +when it is released or destroyed (removed and freed) - no reference +counting. + +devres core guarantees atomicity to all basic devres operations and +has support for single-instance devres types (atomic +lookup-and-add-if-not-found). Other than that, synchronizing +concurrent accesses to allocated devres data is caller's +responsibility. This is usually non-issue because bus ops and +resource allocations already do the job. + +For an example of single-instance devres type, read pcim_iomap_table() +in lib/iomap.c. + +All devres interface functions can be called without context if the +right gfp mask is given. + + + 5. Overhead + ----------- + +Each devres bookkeeping info is allocated together with requested data +area. With debug option turned off, bookkeeping info occupies 16 +bytes on 32bit machines and 24 bytes on 64bit (three pointers rounded +up to ull alignment). If singly linked list is used, it can be +reduced to two pointers (8 bytes on 32bit, 16 bytes on 64bit). + +Each devres group occupies 8 pointers. It can be reduced to 6 if +singly linked list is used. + +Memory space overhead on ahci controller with two ports is between 300 +and 400 bytes on 32bit machine after naive conversion (we can +certainly invest a bit more effort into libata core layer). + + + 6.

It also stresses on the precautions that must be taken when reading +those local variables across CPUs when the order of memory writes matters. + + + +* Purpose of local atomic operations + +Local atomic operations are meant to provide fast and highly reentrant per CPU +counters. They minimize the performance cost of standard atomic operations by +removing the LOCK prefix and memory barriers normally required to synchronize +across CPUs. + +Having fast per CPU atomic counters is interesting in many cases : it does not +require disabling interrupts to protect from interrupt handlers and it permits +coherent counters in NMI handlers. It is especially useful for tracing purposes +and for various performance monitoring counters. + +Local atomic operations only guarantee variable modification atomicity wrt the +CPU which owns the data. Therefore, care must taken to make sure that only one +CPU writes to the local_t data. This is done by using per cpu data and making +sure that we modify it from within a preemption safe context. It is however +permitted to read local_t data from any CPU : it will then appear to be written +out of order wrt other memory writes on the owner CPU. + + +* Implementation for a given architecture + +It can be done by slightly modifying the standard atomic operations : only +their UP variant must be kept. It typically means removing LOCK prefix (on +i386 and x86_64) and any SMP sychronization barrier. If the architecture does +not have a different behavior between SMP and UP, including asm-generic/local.h +in your archtecture's local.h is sufficient. + +The local_t type is defined as an opaque signed long by embedding an +atomic_long_t inside a structure. This is made so a cast from this type to a +long fails.

This differs from radix trees (which +are used to efficiently store sparse arrays and thus use long integer indexes +to insert/access/delete nodes) and hash tables (which are not kept sorted to +be easily traversed in order, and must be tuned for a specific size and +hash function where rbtrees scale gracefully storing arbitrary keys). + +Red-black trees are similar to AVL trees, but provide faster real-time bounded +worst case performance for insertion and deletion (at most two rotations and +three rotations, respectively, to balance the tree), with slightly slower +(but still O(log n)) lookup time. + +To quote Linux Weekly News: + + There are a number of red-black trees in use in the kernel. + The anticipatory, deadline, and CFQ I/O schedulers all employ + rbtrees to track requests; the packet CD/DVD driver does the same. + The high-resolution timer code uses an rbtree to organize outstanding + timer requests. The ext3 filesystem tracks directory entries in a + red-black tree. Virtual memory areas (VMAs) are tracked with red-black + trees, as are epoll file descriptors, cryptographic keys, and network + packets in the "hierarchical token bucket" scheduler. + +This document covers use of the Linux rbtree implementation.

To use it, +"#include ". + +The Linux rbtree implementation is optimized for speed, and thus has one +less layer of indirection (and better cache locality) than more traditional +tree implementations. Instead of using pointers to separate rb_node and data +structures, each instance of struct rb_node is embedded in the data structure +it organizes. And instead of using a comparison callback function pointer, +users are expected to write their own tree search and insert functions +which call the provided rbtree functions. Locking is also left up to the +user of the rbtree code. + +Creating a new rbtree +--------------------- + +Data nodes in an rbtree tree are structures containing a struct rb_node member: + + struct mytype { + struct rb_node node; + char *keystring; + }; + +When dealing with a pointer to the embedded struct rb_node, the containing data +structure may be accessed with the standard container_of() macro.

Description +============== + +Dynamic Audio Power Management (DAPM) is designed to allow portable Linux devices +to use the minimum amount of power within the audio subsystem at all times. It +is independent of other kernel PM and as such, can easily co-exist with the +other PM systems. + +DAPM is also completely transparent to all user space applications as all power +switching is done within the ASoC core. No code changes or recompiling are +required for user space applications. DAPM makes power switching descisions based +upon any audio stream (capture/playback) activity and audio mixer settings +within the device. + +DAPM spans the whole machine. It covers power control within the entire audio +subsystem, this includes internal codec power blocks and machine level power +systems. + +There are 4 power domains within DAPM + + 1. Codec domain - VREF, VMID (core codec and audio power) + Usually controlled at codec probe/remove and suspend/resume, although + can be set at stream time if power is not needed for sidetone, etc. + + 2. Platform/Machine domain - physically connected inputs and outputs + Is platform/machine and user action specific, is configured by the + machine driver and responds to asynchronous events e.g when HP + are inserted + + 3. Path domain - audio susbsystem signal paths + Automatically set when mixer and mux settings are changed by the user. + e.g. alsamixer, amixer. + + 4. Stream domain - DAC's and ADC's. + Enabled and disabled when stream playback/capture is started and + stopped respectively. e.g. aplay, arecord. + +All DAPM power switching descisons are made automatically by consulting an audio +routing map of the whole machine. This map is specific to each machine and +consists of the interconnections between every audio component (including +internal codec components). All audio components that effect power are called +widgets hereafter. + + +2. DAPM Widgets +=============== + +Audio DAPM widgets fall into a number of types:- + + o Mixer - Mixes several analog signals into a single analog signal. + o Mux - An analog switch that outputs only 1 of it's inputs. + o PGA - A programmable gain amplifier or attenuation widget. + o ADC - Analog to Digital Converter + o DAC - Digital to Analog Converter + o Switch - An analog switch + o Input - A codec input pin + o Output - A codec output pin + o Headphone - Headphone (and optional Jack) + o Mic - Mic (and optional Jack) + o Line - Line Input/Output (and optional Jack) + o Speaker - Speaker + o Pre - Special PRE widget (exec before all others) + o Post - Special POST widget (exec after all others) + +(Widgets are defined in include/sound/soc-dapm.h) + +Widgets are usually added in the codec driver and the machine driver. There are +convience macros defined in soc-dapm.h that can be used to quickly build a +list of widgets of the codecs and machines DAPM widgets. + +Most widgets have a name, register, shift and invert. Some widgets have extra +parameters for stream name and kcontrols. + + +2.1 Stream Domain Widgets +------------------------- + +Stream Widgets relate to the stream power domain and only consist of ADC's +(analog to digital converters) and DAC's (digital to analog converters). + +Stream widgets have the following format:- + +SND_SOC_DAPM_DAC(name, stream name, reg, shift, invert), + +NOTE: the stream name must match the corresponding stream name in your codecs +snd_soc_codec_dai. + +e.g. stream widgets for HiFi playback and capture + +SND_SOC_DAPM_DAC("HiFi DAC", "HiFi Playback", REG, 3, 1), +SND_SOC_DAPM_ADC("HiFi ADC", "HiFi Capture", REG, 2, 1), + + +2.2 Path Domain Widgets +----------------------- + +Path domain widgets have a ability to control or effect the audio signal or +audio paths within the audio subsystem. They have the following form:- + +SND_SOC_DAPM_PGA(name, reg, shift, invert, controls, num_controls) + +Any widget kcontrols can be set using the controls and num_controls members. + +e.g. Mixer widget (the kcontrols are declared first) + +/* Output Mixer */ +static const snd_kcontrol_new_t wm8731_output_mixer_controls[] = { +SOC_DAPM_SINGLE("Line Bypass Switch", WM8731_APANA, 3, 1, 0), +SOC_DAPM_SINGLE("Mic Sidetone Switch", WM8731_APANA, 5, 1, 0), +SOC_DAPM_SINGLE("HiFi Playback Switch", WM8731_APANA, 4, 1, 0), +}; + +SND_SOC_DAPM_MIXER("Output Mixer", WM8731_PWR, 4, 1, wm8731_output_mixer_controls, + ARRAY_SIZE(wm8731_output_mixer_controls)), + + +2.3 Platform/Machine domain Widgets +----------------------------------- + +Machine widgets are different from codec widgets in that they don't have a +codec register bit associated with them. A machine widget is assigned to each +machine audio component (non codec) that can be independently powered. e.g. + + o Speaker Amp + o Microphone Bias + o Jack connectors + +A machine widget can have an optional call back. + +e.g. Jack connector widget for an external Mic that enables Mic Bias +when the Mic is inserted:- + +static int spitz_mic_bias(struct snd_soc_dapm_widget* w, int event) +{ + if(SND_SOC_DAPM_EVENT_ON(event)) + set_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS); + else + reset_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS); + + return 0; +} + +SND_SOC_DAPM_MIC("Mic Jack", spitz_mic_bias), + + +2.4 Codec Domain +---------------- + +The Codec power domain has no widgets and is handled by the codecs DAPM event +handler. This handler is called when the codec powerstate is changed wrt to any +stream event or by kernel PM events. + + +2.5 Virtual Widgets +------------------- + +Sometimes widgets exist in the codec or machine audio map that don't have any +corresponding register bit for power control. In this case it's necessary to +create a virtual widget - a widget with no control bits e.g. + +SND_SOC_DAPM_MIXER("AC97 Mixer", SND_SOC_DAPM_NOPM, 0, 0, NULL, 0), + +This can be used to merge to signal paths together in software. + +After all the widgets have been defined, they can then be added to the DAPM +subsystem individually with a call to snd_soc_dapm_new_control(). + + +3. Codec Widget Interconnections +================================ + +Widgets are connected to each other within the codec and machine by audio +paths (called interconnections). Each interconnection must be defined in order +to create a map of all audio paths between widgets. +This is easiest with a diagram of the codec (and schematic of the machine audio +system), as it requires joining widgets together via their audio signal paths. + +i.e. from the WM8731 codec's output mixer (wm8731.c) + +The WM8731 output mixer has 3 inputs (sources) + + 1. Line Bypass Input + 2. DAC (HiFi playback) + 3. Mic Sidetone Input + +Each input in this example has a kcontrol associated with it (defined in example +above) and is connected to the output mixer via it's kcontrol name. We can now +connect the destination widget (wrt audio signal) with it's source widgets. + + /* output mixer */ + {"Output Mixer", "Line Bypass Switch", "Line Input"}, + {"Output Mixer", "HiFi Playback Switch", "DAC"}, + {"Output Mixer", "Mic Sidetone Switch", "Mic Bias"}, + +So we have :- + + Destination Widget <=== Path Name <=== Source Widget + +Or:- + + Sink, Path, Source + +Or :- + + "Output Mixer" is connected to the "DAC" via the "HiFi Playback Switch". + +When there is no path name connecting widgets (e.g. a direct connection) we +pass NULL for the path name. + +Interconnections are created with a call to:- + +snd_soc_dapm_connect_input(codec, sink, path, source); + +Finally, snd_soc_dapm_new_widgets(codec) must be called after all widgets and +interconnections have been registered with the core. This causes the core to +scan the codec and machine so that the internal DAPM state matches the +physical state of the machine. + + +3.1 Machine Widget Interconnections +----------------------------------- +Machine widget interconnections are created in the same way as codec ones and +directly connect the codec pins to machine level widgets. + +e.g. connects the speaker out codec pins to the internal speaker. + + /* ext speaker connected to codec pins LOUT2, ROUT2 */ + {"Ext Spk", NULL , "ROUT2"}, + {"Ext Spk", NULL , "LOUT2"}, + +This allows the DAPM to power on and off pins that are connected (and in use) +and pins that are NC respectively. + + +4 Endpoint Widgets +=================== +An endpoint is a start or end point (widget) of an audio signal within the +machine and includes the codec. e.g. + + o Headphone Jack + o Internal Speaker + o Internal Mic + o Mic Jack + o Codec Pins + +When a codec pin is NC it can be marked as not used with a call to + +snd_soc_dapm_set_endpoint(codec, "Widget Name", 0); + +The last argument is 0 for inactive and 1 for active. This way the pin and its +input widget will never be powered up and consume power. + +This also applies to machine widgets. e.g. if a headphone is connected to a +jack then the jack can be marked active. If the headphone is removed, then +the headphone jack can be marked inactive. + + +5 DAPM Widget Events +==================== + +Some widgets can register their interest with the DAPM core in PM events. +e.g. A Speaker with an amplifier registers a widget so the amplifier can be +powered only when the spk is in use. + +/* turn speaker amplifier on/off depending on use */ +static int corgi_amp_event(struct snd_soc_dapm_widget *w, int event) +{ + if (SND_SOC_DAPM_EVENT_ON(event)) + set_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON); + else + reset_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON); + + return 0; +} + +/* corgi machine dapm widgets */ +static const struct snd_soc_dapm_widget wm8731_dapm_widgets = + SND_SOC_DAPM_SPK("Ext Spk", corgi_amp_event); + +Please see soc-dapm.h for all other widgets that support events. + + +5.1 Event types +--------------- + +The following event types are supported by event widgets. + +/* dapm event types */ +#define SND_SOC_DAPM_PRE_PMU 0x1 /* before widget power up */ +#define SND_SOC_DAPM_POST_PMU 0x2 /* after widget power up */ +#define SND_SOC_DAPM_PRE_PMD 0x4 /* before widget power down */ +#define SND_SOC_DAPM_POST_PMD 0x8 /* after widget power down */ +#define SND_SOC_DAPM_PRE_REG 0x10 /* before audio path setup */ +#define SND_SOC_DAPM_POST_REG 0x20 /* after audio path setup */ diff --git a/trunk/Documentation/sound/alsa/soc/machine.txt b/trunk/Documentation/sound/alsa/soc/machine.txt new file mode 100644 index 000000000000..72bd222f2a21 --- /dev/null +++ b/trunk/Documentation/sound/alsa/soc/machine.txt @@ -0,0 +1,113 @@ +ASoC Machine Driver +=================== + +The ASoC machine (or board) driver is the code that glues together the platform +and codec drivers. + +The machine driver can contain codec and platform specific code.
