-5.3.2 Handling MSI-X allocation
-
-Determining the number of MSI-X vectors allocated to a function is
-dependent on the number of MSI capable devices and MSI-X capable
-devices populated in the system. The policy of allocating MSI-X
-vectors to a function is defined as the following:
-
-#of MSI-X vectors allocated to a function = (x - y)/z where
-
-x = 	The number of available PCI vector resources by the time
-	the device driver calls pci_enable_msix(). The PCI vector
-	resources is the sum of the number of unassigned vectors
-	(new) and the number of released vectors when any MSI/MSI-X
-	device driver switches its hardware device back to a legacy
-	mode or is hot-removed.	The number of unassigned vectors
-	may exclude some vectors reserved, as defined in parameter
-	NR_HP_RESERVED_VECTORS, for the case where the system is
-	capable of supporting hot-add/hot-remove operations. Users
-	may change the value defined in NR_HR_RESERVED_VECTORS to
-	meet their specific needs.
-
-y =	The number of MSI capable devices populated in the system.
-	This policy ensures that each MSI capable device has its
-	vector reserved to avoid the case where some MSI-X capable
-	drivers may attempt to claim all available vector resources.
-
-z =	The number of MSI-X capable devices populated in the system.
-	This policy ensures that maximum (x - y) is distributed
-	evenly among MSI-X capable devices.
-
-Note that the PCI subsystem scans y and z during a bus enumeration.
-When the PCI subsystem completes configuring MSI/MSI-X capability
-structure of a device as requested by its device driver, y/z is
-decremented accordingly.
-
-5.3.3 Handling MSI-X shortages
-
-For the case where fewer MSI-X vectors are allocated to a function
-than requested, the function pci_enable_msix() will return the
-maximum number of MSI-X vectors available to the caller. A device
-driver may re-send its request with fewer or equal vectors indicated
-in the return. For example, if a device driver requests 5 vectors, but
-the number of available vectors is 3 vectors, a value of 3 will be
-returned as a result of pci_enable_msix() call. A function could be
-designed for its driver to use only 3 MSI-X table entries as
-different combinations as ABC--, A-B-C, A--CB, etc. Note that this
-patch does not support multiple entries with the same vector. Such
-attempt by a device driver to use 5 MSI-X table entries with 3 vectors
-as ABBCC, AABCC, BCCBA, etc will result as a failure by the function
-pci_enable_msix(). Below are the reasons why supporting multiple
-entries with the same vector is an undesirable solution.
-
-	- The PCI subsystem cannot determine the entry that
-	  generated the message to mask/unmask MSI while handling
-	  software driver ISR. Attempting to walk through all MSI-X

+0. Why you should avoid mandatory locking
+-----------------------------------------
+
+The Linux implementation is prey to a number of difficult-to-fix race
+conditions which in practice make it not dependable:
+
+	- The write system call checks for a mandatory lock only once
+	  at its start.  It is therefore possible for a lock request to
+	  be granted after this check but before the data is modified.
+	  A process may then see file data change even while a mandatory
+	  lock was held.
+	- Similarly, an exclusive lock may be granted on a file after
+	  the kernel has decided to proceed with a read, but before the
+	  read has actually completed, and the reading process may see
+	  the file data in a state which should not have been visible
+	  to it.
+	- Similar races make the claimed mutual exclusion between lock
+	  and mmap similarly unreliable.

+sysfs attribute writes interpretation
+-------------------------------------
+
+hwmon sysfs attributes always contain numbers, so the first thing to do is to
+convert the input to a number, there are 2 ways todo this depending whether
+the number can be negative or not:
+unsigned long u = simple_strtoul(buf, NULL, 10);
+long s = simple_strtol(buf, NULL, 10);
+
+With buf being the buffer with the user input being passed by the kernel.
+Notice that we do not use the second argument of strto[u]l, and thus cannot
+tell when 0 is returned, if this was really 0 or is caused by invalid input.
+This is done deliberately as checking this everywhere would add a lot of
+code to the kernel.
+
+Notice that it is important to always store the converted value in an
+unsigned long or long, so that no wrap around can happen before any further
+checking.
+
+After the input string is converted to an (unsigned) long, the value should be
+checked if its acceptable. Be careful with further conversions on the value
+before checking it for validity, as these conversions could still cause a wrap
+around before the check. For example do not multiply the result, and only
+add/subtract if it has been divided before the add/subtract.
+
+What to do if a value is found to be invalid, depends on the type of the
+sysfs attribute that is being set. If it is a continuous setting like a
+tempX_max or inX_max attribute, then the value should be clamped to its
+limits using SENSORS_LIMIT(value, min_limit, max_limit). If it is not
+continuous like for example a tempX_type, then when an invalid value is
+written, -EINVAL should be returned.
+
+Example1, temp1_max, register is a signed 8 bit value (-128 - 127 degrees):
+
+	long v = simple_strtol(buf, NULL, 10) / 1000;
+	v = SENSORS_LIMIT(v, -128, 127);
+	/* write v to register */
+
+Example2, fan divider setting, valid values 2, 4 and 8:
+
+	unsigned long v = simple_strtoul(buf, NULL, 10);
+
+	switch (v) {
+	case 2: v = 1; break;
+	case 4: v = 2; break;
+	case 8: v = 3; break;
+	default:
+		return -EINVAL;

-
-*** NOTE: It is the responsibility of user-space code to handle the fact
-that the beep enable and alarm bits are in different positions when using that
-feature of the chip.
-
-When an alarm goes off, you can be warned by a beeping signal through your
-computer speaker. It is possible to enable all beeping globally, or only
-the beeping for some alarms.
-
-The driver only reads the chip values each 3 seconds; reading them more
-often will do no harm, but will return 'old' values.
+The w83791d has a global bit used to enable beeping from the speaker when an
+alarm is triggered as well as a bitmask to enable or disable the beep for
+specific alarms. You need both the global beep enable bit and the
+corresponding beep bit to be on for a triggered alarm to sound a beep.
+
+The sysfs interface to the gloabal enable is via the sysfs beep_enable file.
+This file is used for both legacy and new code.
+
+The sysfs interface to the beep bitmask has migrated from the original legacy
+method of a single sysfs beep_mask file to a newer method using multiple
+*_beep files as described in .../Documentation/hwmon/sysfs-interface.
+
+A similar change has occured for the bitmap corresponding to the alarms. The
+original legacy method used a single sysfs alarms file containing a bitmap
+of triggered alarms. The newer method uses multiple sysfs *_alarm files
+(again following the pattern described in sysfs-interface).
+
+Since both methods read and write the underlying hardware, they can be used
+interchangeably and changes in one will automatically be reflected by
+the other. If you use the legacy bitmask method, your user-space code is
+responsible for handling the fact that the alarms and beep_mask bitmaps
+are not the same (see the table below).
+
+NOTE: All new code should be written to use the newer sysfs-interface
+specification as that avoids bitmap problems and is the preferred interface
+going forward.
+
+The driver reads the hardware chip values at most once every three seconds.
+User mode code requesting values more often will receive cached values.

+
+	The down side of fail over MAC is that every device on the

+	traffic, not just ARP traffic, if the switch snoops incoming
+	traffic to update its tables) for the traditional method.  If
+	the gratuitous ARP is lost, communication may be disrupted.
+
+	When fail over MAC is used in conjuction with the mii monitor,

+Group scheduler extension to CFS
+================================
+
+Normally the scheduler operates on individual tasks and strives to provide
+fair CPU time to each task. Sometimes, it may be desirable to group tasks
+and provide fair CPU time to each such task group. For example, it may
+be desirable to first provide fair CPU time to each user on the system
+and then to each task belonging to a user.
+
+CONFIG_FAIR_GROUP_SCHED strives to achieve exactly that. It lets
+SCHED_NORMAL/BATCH tasks be be grouped and divides CPU time fairly among such
+groups. At present, there are two (mutually exclusive) mechanisms to group
+tasks for CPU bandwidth control purpose:
+
+	- Based on user id (CONFIG_FAIR_USER_SCHED)
+		In this option, tasks are grouped according to their user id.
+	- Based on "cgroup" pseudo filesystem (CONFIG_FAIR_CGROUP_SCHED)
+		This options lets the administrator create arbitrary groups
+		of tasks, using the "cgroup" pseudo filesystem. See
+		Documentation/cgroups.txt for more information about this
+		filesystem.
+
+Only one of these options to group tasks can be chosen and not both.
+
+Group scheduler tunables:
+
+When CONFIG_FAIR_USER_SCHED is defined, a directory is created in sysfs for
+each new user and a "cpu_share" file is added in that directory.
+
+	# cd /sys/kernel/uids
+	# cat 512/cpu_share		# Display user 512's CPU share
+	1024
+	# echo 2048 > 512/cpu_share	# Modify user 512's CPU share
+	# cat 512/cpu_share		# Display user 512's CPU share
+	2048
+	#
+
+CPU bandwidth between two users are divided in the ratio of their CPU shares.
+For ex: if you would like user "root" to get twice the bandwidth of user
+"guest", then set the cpu_share for both the users such that "root"'s
+cpu_share is twice "guest"'s cpu_share
+
+
+When CONFIG_FAIR_CGROUP_SCHED is defined, a "cpu.shares" file is created
+for each group created using the pseudo filesystem. See example steps
+below to create task groups and modify their CPU share using the "cgroups"
+pseudo filesystem
+
+	# mkdir /dev/cpuctl
+	# mount -t cgroup -ocpu none /dev/cpuctl
+	# cd /dev/cpuctl
+
+	# mkdir multimedia	# create "multimedia" group of tasks
+	# mkdir browser		# create "browser" group of tasks
+
+	# #Configure the multimedia group to receive twice the CPU bandwidth
+	# #that of browser group
+
+	# echo 2048 > multimedia/cpu.shares
+	# echo 1024 > browser/cpu.shares
+
+	# firefox &	# Launch firefox and move it to "browser" group
+	# echo <firefox_pid> > browser/tasks
+
+	# #Launch gmplayer (or your favourite movie player)
+	# echo <movie_player_pid> > multimedia/tasks

+Driver Compile Time Options and Debugging
+
+The following constants can be defined in the source file.
+
+1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled)
+
+   Enabling this option adds assertion logic statements to the
+   driver. If an assertion fails a message will be displayed to
+   the console, but the system will continue to operate. Any
+   assertions encountered should be reported to the person
+   responsible for the driver. Assertion statements may proactively
+   detect problems with the driver and facilitate fixing these
+   problems. Enabling assertions will add a small overhead to the
+   execution of the driver.
+
+2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled)
+
+   Enabling this option adds tracing functions to the driver and the
+   ability to set a driver tracing level at boot time.  This option is
+   very useful for debugging the driver, but it will add to the size
+   of the driver execution image and add overhead to the execution of
+   the driver.
+
+   The amount of debugging output can be controlled with the global
+   variable 'asc_dbglvl'. The higher the number the more output. By
+   default the debug level is 0.
+
+   If the driver is loaded at boot time and the LILO Driver Option
+   is included in the system, the debug level can be changed by
+   specifying a 5th (ASC_NUM_IOPORT_PROBE + 1) I/O Port. The
+   first three hex digits of the pseudo I/O Port must be set to
+   'deb' and the fourth hex digit specifies the debug level: 0 - F.
+   The following command line will look for an adapter at 0x330
+   and set the debug level to 2.
+
+      linux advansys=0x330,0,0,0,0xdeb2
+
+   If the driver is built as a loadable module this variable can be
+   defined when the driver is loaded. The following insmod command
+   will set the debug level to one.
+
+      insmod advansys.o asc_dbglvl=1
+
+   Debugging Message Levels:
+      0: Errors Only
+      1: High-Level Tracing
+      2-N: Verbose Tracing
+
+   To enable debug output to console, please make sure that:
+
+   a. System and kernel logging is enabled (syslogd, klogd running).
+   b. Kernel messages are routed to console output. Check
+      /etc/syslog.conf for an entry similar to this:
+
+           kern.*                  /dev/console
+
+   c. klogd is started with the appropriate -c parameter
+      (e.g. klogd -c 8)
+
+   This will cause printk() messages to be be displayed on the
+   current console. Refer to the klogd(8) and syslogd(8) man pages
+   for details.
+
+   Alternatively you can enable printk() to console with this
+   program. However, this is not the 'official' way to do this.
+   Debug output is logged in /var/log/messages.
+
+     main()
+     {
+             syscall(103, 7, 0, 0);
+     }
+
+   Increasing LOG_BUF_LEN in kernel/printk.c to something like
+   40960 allows more debug messages to be buffered in the kernel
+   and written to the console or log file.
+
+3. ADVANSYS_STATS - Enable statistics (Def: Enabled)
+
+   Enabling this option adds statistics collection and display
+   through /proc to the driver. The information is useful for
+   monitoring driver and device performance. It will add to the
+   size of the driver execution image and add minor overhead to
+   the execution of the driver.
+
+   Statistics are maintained on a per adapter basis. Driver entry
+   point call counts and transfer size counts are maintained.
+   Statistics are only available for kernels greater than or equal
+   to v1.3.0 with the CONFIG_PROC_FS (/proc) file system configured.
+
+   AdvanSys SCSI adapter files have the following path name format:
+
+      /proc/scsi/advansys/{0,1,2,3,...}
+
+   This information can be displayed with cat. For example:
+
+      cat /proc/scsi/advansys/0
+
+   When ADVANSYS_STATS is not defined the AdvanSys /proc files only
+   contain adapter and device configuration information.
+
+Driver LILO Option
+
+If init/main.c is modified as described in the 'Directions for Adding
+the AdvanSys Driver to Linux' section (B.4.) above, the driver will
+recognize the 'advansys' LILO command line and /etc/lilo.conf option.
+This option can be used to either disable I/O port scanning or to limit
+scanning to 1 - 4 I/O ports. Regardless of the option setting EISA and
+PCI boards will still be searched for and detected. This option only
+affects searching for ISA and VL boards.
+
+Examples:
+  1. Eliminate I/O port scanning:
+       boot: linux advansys=
+         or
+       boot: linux advansys=0x0
+  2. Limit I/O port scanning to one I/O port:
+       boot: linux advansys=0x110
+  3. Limit I/O port scanning to four I/O ports:
+       boot: linux advansys=0x110,0x210,0x230,0x330
+
+For a loadable module the same effect can be achieved by setting
+the 'asc_iopflag' variable and 'asc_ioport' array when loading
+the driver, e.g.
+
+      insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330
+
+If ADVANSYS_DEBUG is defined a 5th (ASC_NUM_IOPORT_PROBE + 1)
+I/O Port may be added to specify the driver debug level. Refer to
+the 'Driver Compile Time Options and Debugging' section above for
+more information.

+
+Authorizing (or not) your USB devices to connect to the system
+
+(C) 2007 Inaky Perez-Gonzalez <inaky@linux.intel.com> Intel Corporation
+
+This feature allows you to control if a USB device can be used (or
+not) in a system. This feature will allow you to implement a lock-down
+of USB devices, fully controlled by user space.
+
+As of now, when a USB device is connected it is configured and
+it's interfaces inmediately made available to the users. With this
+modification, only if root authorizes the device to be configured will
+then it be possible to use it.
+
+Usage:
+
+Authorize a device to connect:
+
+$ echo 1 > /sys/usb/devices/DEVICE/authorized
+
+Deauthorize a device:
+
+$ echo 0 > /sys/usb/devices/DEVICE/authorized
+
+Set new devices connected to hostX to be deauthorized by default (ie:
+lock down):
+
+$ echo 0 > /sys/bus/devices/usbX/authorized_default
+
+Remove the lock down:
+
+$ echo 1 > /sys/bus/devices/usbX/authorized_default
+
+By default, Wired USB devices are authorized by default to
+connect. Wireless USB hosts deauthorize by default all new connected
+devices (this is so because we need to do an authentication phase
+before authorizing).
+
+
+Example system lockdown (lame)
+-----------------------
+
+Imagine you want to implement a lockdown so only devices of type XYZ
+can be connected (for example, it is a kiosk machine with a visible
+USB port):
+
+boot up
+rc.local ->
+
+ for host in /sys/bus/devices/usb*
+ do
+    echo 0 > $host/authorized_default
+ done
+
+Hookup an script to udev, for new USB devices
+
+ if device_is_my_type $DEV
+ then
+   echo 1 > $device_path/authorized
+ done
+
+
+Now, device_is_my_type() is where the juice for a lockdown is. Just
+checking if the class, type and protocol match something is the worse
+security verification you can make (or the best, for someone willing
+to break it). If you need something secure, use crypto and Certificate
+Authentication or stuff like that. Something simple for an storage key
+could be:
+
+function device_is_my_type()
+{
+   echo 1 > authorized		# temporarily authorize it
+                                # FIXME: make sure none can mount it
+   mount DEVICENODE /mntpoint
+   sum=$(md5sum /mntpoint/.signature)
+   if [ $sum = $(cat /etc/lockdown/keysum) ]
+   then
+        echo "We are good, connected"
+        umount /mntpoint
+        # Other stuff so others can use it
+   else
+        echo 0 > authorized
+   fi
+}
+
+
+Of course, this is lame, you'd want to do a real certificate
+verification stuff with PKI, so you don't depend on a shared secret,
+etc, but you get the idea. Anybody with access to a device gadget kit
+can fake descriptors and device info. Don't trust that. You are
+welcome.

+			Power Management for USB
+
+		 Alan Stern <stern@rowland.harvard.edu>
+
+			    October 5, 2007
+
+
+
+	What is Power Management?
+	-------------------------
+
+Power Management (PM) is the practice of saving energy by suspending
+parts of a computer system when they aren't being used.  While a
+component is "suspended" it is in a nonfunctional low-power state; it
+might even be turned off completely.  A suspended component can be
+"resumed" (returned to a functional full-power state) when the kernel
+needs to use it.  (There also are forms of PM in which components are
+placed in a less functional but still usable state instead of being
+suspended; an example would be reducing the CPU's clock rate.  This
+document will not discuss those other forms.)
+
+When the parts being suspended include the CPU and most of the rest of
+the system, we speak of it as a "system suspend".  When a particular
+device is turned off while the system as a whole remains running, we
+call it a "dynamic suspend" (also known as a "runtime suspend" or
+"selective suspend").  This document concentrates mostly on how
+dynamic PM is implemented in the USB subsystem, although system PM is
+covered to some extent (see Documentation/power/*.txt for more
+information about system PM).
+
+Note: Dynamic PM support for USB is present only if the kernel was
+built with CONFIG_USB_SUSPEND enabled.  System PM support is present
+only if the kernel was built with CONFIG_SUSPEND or CONFIG_HIBERNATION
+enabled.
+
+
+	What is Remote Wakeup?
+	----------------------
+
+When a device has been suspended, it generally doesn't resume until
+the computer tells it to.  Likewise, if the entire computer has been
+suspended, it generally doesn't resume until the user tells it to, say
+by pressing a power button or opening the cover.
+
+However some devices have the capability of resuming by themselves, or
+asking the kernel to resume them, or even telling the entire computer
+to resume.  This capability goes by several names such as "Wake On
+LAN"; we will refer to it generically as "remote wakeup".  When a
+device is enabled for remote wakeup and it is suspended, it may resume
+itself (or send a request to be resumed) in response to some external
+event.  Examples include a suspended keyboard resuming when a key is
+pressed, or a suspended USB hub resuming when a device is plugged in.
+
+
+	When is a USB device idle?
+	--------------------------
+
+A device is idle whenever the kernel thinks it's not busy doing
+anything important and thus is a candidate for being suspended.  The
+exact definition depends on the device's driver; drivers are allowed
+to declare that a device isn't idle even when there's no actual
+communication taking place.  (For example, a hub isn't considered idle
+unless all the devices plugged into that hub are already suspended.)
+In addition, a device isn't considered idle so long as a program keeps
+its usbfs file open, whether or not any I/O is going on.
+
+If a USB device has no driver, its usbfs file isn't open, and it isn't
+being accessed through sysfs, then it definitely is idle.
+
+
+	Forms of dynamic PM
+	-------------------
+
+Dynamic suspends can occur in two ways: manual and automatic.
+"Manual" means that the user has told the kernel to suspend a device,
+whereas "automatic" means that the kernel has decided all by itself to
+suspend a device.  Automatic suspend is called "autosuspend" for
+short.  In general, a device won't be autosuspended unless it has been
+idle for some minimum period of time, the so-called idle-delay time.
+
+Of course, nothing the kernel does on its own initiative should
+prevent the computer or its devices from working properly.  If a
+device has been autosuspended and a program tries to use it, the
+kernel will automatically resume the device (autoresume).  For the
+same reason, an autosuspended device will usually have remote wakeup
+enabled, if the device supports remote wakeup.
+
+It is worth mentioning that many USB drivers don't support
+autosuspend.  In fact, at the time of this writing (Linux 2.6.23) the
+only drivers which do support it are the hub driver, kaweth, asix,
+usblp, usblcd, and usb-skeleton (which doesn't count).  If a
+non-supporting driver is bound to a device, the device won't be
+autosuspended.  In effect, the kernel pretends the device is never
+idle.
+
+We can categorize power management events in two broad classes:
+external and internal.  External events are those triggered by some
+agent outside the USB stack: system suspend/resume (triggered by
+userspace), manual dynamic suspend/resume (also triggered by
+userspace), and remote wakeup (triggered by the device).  Internal
+events are those triggered within the USB stack: autosuspend and
+autoresume.
+
+
+	The user interface for dynamic PM
+	---------------------------------
+
+The user interface for controlling dynamic PM is located in the power/
+subdirectory of each USB device's sysfs directory, that is, in
+/sys/bus/usb/devices/.../power/ where "..." is the device's ID.  The
+relevant attribute files are: wakeup, level, and autosuspend.

+
+		This file is empty if the device does not support
+		remote wakeup.  Otherwise the file contains either the
+		word "enabled" or the word "disabled", and you can
+		write those words to the file.  The setting determines
+		whether or not remote wakeup will be enabled when the
+		device is next suspended.  (If the setting is changed
+		while the device is suspended, the change won't take
+		effect until the following suspend.)
+
+	power/level
+
+		This file contains one of three words: "on", "auto",
+		or "suspend".  You can write those words to the file
+		to change the device's setting.
+
+		"on" means that the device should be resumed and
+		autosuspend is not allowed.  (Of course, system
+		suspends are still allowed.)
+
+		"auto" is the normal state in which the kernel is
+		allowed to autosuspend and autoresume the device.
+
+		"suspend" means that the device should remain
+		suspended, and autoresume is not allowed.  (But remote
+		wakeup may still be allowed, since it is controlled
+		separately by the power/wakeup attribute.)
+
+	power/autosuspend
+
+		This file contains an integer value, which is the
+		number of seconds the device should remain idle before
+		the kernel will autosuspend it (the idle-delay time).
+		The default is 2.  0 means to autosuspend as soon as
+		the device becomes idle, and -1 means never to
+		autosuspend.  You can write a number to the file to
+		change the autosuspend idle-delay time.
+
+Writing "-1" to power/autosuspend and writing "on" to power/level do
+essentially the same thing -- they both prevent the device from being
+autosuspended.  Yes, this is a redundancy in the API.
+
+(In 2.6.21 writing "0" to power/autosuspend would prevent the device
+from being autosuspended; the behavior was changed in 2.6.22.  The
+power/autosuspend attribute did not exist prior to 2.6.21, and the
+power/level attribute did not exist prior to 2.6.22.)
+
+
+	Changing the default idle-delay time
+	------------------------------------
+
+The default autosuspend idle-delay time is controlled by a module
+parameter in usbcore.  You can specify the value when usbcore is
+loaded.  For example, to set it to 5 seconds instead of 2 you would
+do:
+
+	modprobe usbcore autosuspend=5
+
+Equivalently, you could add to /etc/modprobe.conf a line saying:
+
+	options usbcore autosuspend=5
+
+Some distributions load the usbcore module very early during the boot
+process, by means of a program or script running from an initramfs
+image.  To alter the parameter value you would have to rebuild that
+image.
+
+If usbcore is compiled into the kernel rather than built as a loadable
+module, you can add
+
+	usbcore.autosuspend=5
+
+to the kernel's boot command line.
+
+Finally, the parameter value can be changed while the system is
+running.  If you do:
+
+	echo 5 >/sys/module/usbcore/parameters/autosuspend
+
+then each new USB device will have its autosuspend idle-delay
+initialized to 5.  (The idle-delay values for already existing devices
+will not be affected.)
+
+Setting the initial default idle-delay to -1 will prevent any
+autosuspend of any USB device.  This is a simple alternative to
+disabling CONFIG_USB_SUSPEND and rebuilding the kernel, and it has the
+added benefit of allowing you to enable autosuspend for selected
+devices.
+
+
+	Warnings
+	--------
+
+The USB specification states that all USB devices must support power
+management.  Nevertheless, the sad fact is that many devices do not
+support it very well.  You can suspend them all right, but when you
+try to resume them they disconnect themselves from the USB bus or
+they stop working entirely.  This seems to be especially prevalent
+among printers and scanners, but plenty of other types of device have
+the same deficiency.
+
+For this reason, by default the kernel disables autosuspend (the
+power/level attribute is initialized to "on") for all devices other
+than hubs.  Hubs, at least, appear to be reasonably well-behaved in
+this regard.
+
+(In 2.6.21 and 2.6.22 this wasn't the case.  Autosuspend was enabled
+by default for almost all USB devices.  A number of people experienced
+problems as a result.)
+
+This means that non-hub devices won't be autosuspended unless the user
+or a program explicitly enables it.  As of this writing there aren't
+any widespread programs which will do this; we hope that in the near
+future device managers such as HAL will take on this added
+responsibility.  In the meantime you can always carry out the
+necessary operations by hand or add them to a udev script.  You can
+also change the idle-delay time; 2 seconds is not the best choice for
+every device.
+
+Sometimes it turns out that even when a device does work okay with
+autosuspend there are still problems.  For example, there are
+experimental patches adding autosuspend support to the usbhid driver,
+which manages keyboards and mice, among other things.  Tests with a
+number of keyboards showed that typing on a suspended keyboard, while
+causing the keyboard to do a remote wakeup all right, would
+nonetheless frequently result in lost keystrokes.  Tests with mice
+showed that some of them would issue a remote-wakeup request in
+response to button presses but not to motion, and some in response to
+neither.
+
+The kernel will not prevent you from enabling autosuspend on devices
+that can't handle it.  It is even possible in theory to damage a
+device by suspending it at the wrong time -- for example, suspending a
+USB hard disk might cause it to spin down without parking the heads.
+(Highly unlikely, but possible.)  Take care.
+
+
+	The driver interface for Power Management
+	-----------------------------------------
+
+The requirements for a USB driver to support external power management
+are pretty modest; the driver need only define
+
+	.suspend
+	.resume
+	.reset_resume
+
+methods in its usb_driver structure, and the reset_resume method is
+optional.  The methods' jobs are quite simple:
+
+	The suspend method is called to warn the driver that the
+	device is going to be suspended.  If the driver returns a
+	negative error code, the suspend will be aborted.  Normally
+	the driver will return 0, in which case it must cancel all
+	outstanding URBs (usb_kill_urb()) and not submit any more.
+
+	The resume method is called to tell the driver that the
+	device has been resumed and the driver can return to normal
+	operation.  URBs may once more be submitted.
+
+	The reset_resume method is called to tell the driver that
+	the device has been resumed and it also has been reset.
+	The driver should redo any necessary device initialization,
+	since the device has probably lost most or all of its state
+	(although the interfaces will be in the same altsettings as
+	before the suspend).
+
+The reset_resume method is used by the USB Persist facility (see
+Documentation/usb/persist.txt) and it can also be used under certain
+circumstances when CONFIG_USB_PERSIST is not enabled.  Currently, if a
+device is reset during a resume and the driver does not have a
+reset_resume method, the driver won't receive any notification about
+the resume.  Later kernels will call the driver's disconnect method;
+2.6.23 doesn't do this.
+
+USB drivers are bound to interfaces, so their suspend and resume
+methods get called when the interfaces are suspended or resumed.  In
+principle one might want to suspend some interfaces on a device (i.e.,
+force the drivers for those interface to stop all activity) without
+suspending the other interfaces.  The USB core doesn't allow this; all
+interfaces are suspended when the device itself is suspended and all
+interfaces are resumed when the device is resumed.  It isn't possible
+to suspend or resume some but not all of a device's interfaces.  The
+closest you can come is to unbind the interfaces' drivers.
+
+
+	The driver interface for autosuspend and autoresume
+	---------------------------------------------------
+
+To support autosuspend and autoresume, a driver should implement all
+three of the methods listed above.  In addition, a driver indicates
+that it supports autosuspend by setting the .supports_autosuspend flag
+in its usb_driver structure.  It is then responsible for informing the
+USB core whenever one of its interfaces becomes busy or idle.  The
+driver does so by calling these three functions:
+
+	int  usb_autopm_get_interface(struct usb_interface *intf);
+	void usb_autopm_put_interface(struct usb_interface *intf);
+	int  usb_autopm_set_interface(struct usb_interface *intf);
+
+The functions work by maintaining a counter in the usb_interface
+structure.  When intf->pm_usage_count is > 0 then the interface is
+deemed to be busy, and the kernel will not autosuspend the interface's
+device.  When intf->pm_usage_count is <= 0 then the interface is
+considered to be idle, and the kernel may autosuspend the device.
+
+(There is a similar pm_usage_count field in struct usb_device,
+associated with the device itself rather than any of its interfaces.
+This field is used only by the USB core.)
+
+The driver owns intf->pm_usage_count; it can modify the value however
+and whenever it likes.  A nice aspect of the usb_autopm_* routines is
+that the changes they make are protected by the usb_device structure's
+PM mutex (udev->pm_mutex); however drivers may change pm_usage_count
+without holding the mutex.
+
+	usb_autopm_get_interface() increments pm_usage_count and
+	attempts an autoresume if the new value is > 0 and the
+	device is suspended.
+
+	usb_autopm_put_interface() decrements pm_usage_count and
+	attempts an autosuspend if the new value is <= 0 and the
+	device isn't suspended.
+
+	usb_autopm_set_interface() leaves pm_usage_count alone.
+	It attempts an autoresume if the value is > 0 and the device
+	is suspended, and it attempts an autosuspend if the value is
+	<= 0 and the device isn't suspended.
+
+There also are a couple of utility routines drivers can use:
+
+	usb_autopm_enable() sets pm_usage_cnt to 1 and then calls
+	usb_autopm_set_interface(), which will attempt an autoresume.
+
+	usb_autopm_disable() sets pm_usage_cnt to 0 and then calls
+	usb_autopm_set_interface(), which will attempt an autosuspend.
+
+The conventional usage pattern is that a driver calls
+usb_autopm_get_interface() in its open routine and
+usb_autopm_put_interface() in its close or release routine.  But
+other patterns are possible.
+
+The autosuspend attempts mentioned above will often fail for one
+reason or another.  For example, the power/level attribute might be
+set to "on", or another interface in the same device might not be
+idle.  This is perfectly normal.  If the reason for failure was that
+the device hasn't been idle for long enough, a delayed workqueue
+routine is automatically set up to carry out the operation when the
+autosuspend idle-delay has expired.
+
+Autoresume attempts also can fail.  This will happen if power/level is
+set to "suspend" or if the device doesn't manage to resume properly.
+Unlike autosuspend, there's no delay for an autoresume.
+
+
+	Other parts of the driver interface
+	-----------------------------------
+
+Sometimes a driver needs to make sure that remote wakeup is enabled
+during autosuspend.  For example, there's not much point
+autosuspending a keyboard if the user can't cause the keyboard to do a
+remote wakeup by typing on it.  If the driver sets
+intf->needs_remote_wakeup to 1, the kernel won't autosuspend the
+device if remote wakeup isn't available or has been disabled through
+the power/wakeup attribute.  (If the device is already autosuspended,
+though, setting this flag won't cause the kernel to autoresume it.
+Normally a driver would set this flag in its probe method, at which
+time the device is guaranteed not to be autosuspended.)
+
+The usb_autopm_* routines have to run in a sleepable process context;
+they must not be called from an interrupt handler or while holding a
+spinlock.  In fact, the entire autosuspend mechanism is not well geared
+toward interrupt-driven operation.  However there is one thing a
+driver can do in an interrupt handler:
+
+	usb_mark_last_busy(struct usb_device *udev);
+
+This sets udev->last_busy to the current time.  udev->last_busy is the
+field used for idle-delay calculations; updating it will cause any
+pending autosuspend to be moved back.  The usb_autopm_* routines will
+also set the last_busy field to the current time.
+
+Calling urb_mark_last_busy() from within an URB completion handler is
+subject to races: The kernel may have just finished deciding the
+device has been idle for long enough but not yet gotten around to
+calling the driver's suspend method.  The driver would have to be
+responsible for synchronizing its suspend method with its URB
+completion handler and causing the autosuspend to fail with -EBUSY if
+an URB had completed too recently.
+
+External suspend calls should never be allowed to fail in this way,
+only autosuspend calls.  The driver can tell them apart by checking
+udev->auto_pm; this flag will be set to 1 for internal PM events
+(autosuspend or autoresume) and 0 for external PM events.
+
+Many of the ingredients in the autosuspend framework are oriented
+towards interfaces: The usb_interface structure contains the
+pm_usage_cnt field, and the usb_autopm_* routines take an interface
+pointer as their argument.  But somewhat confusingly, a few of the
+pieces (usb_mark_last_busy() and udev->auto_pm) use the usb_device
+structure instead.  Drivers need to keep this straight; they can call
+interface_to_usbdev() to find the device structure for a given
+interface.
+
+
+	Locking requirements
+	--------------------
+
+All three suspend/resume methods are always called while holding the
+usb_device's PM mutex.  For external events -- but not necessarily for
+autosuspend or autoresume -- the device semaphore (udev->dev.sem) will
+also be held.  This implies that external suspend/resume events are
+mutually exclusive with calls to probe, disconnect, pre_reset, and
+post_reset; the USB core guarantees that this is true of internal
+suspend/resume events as well.
+
+If a driver wants to block all suspend/resume calls during some
+critical section, it can simply acquire udev->pm_mutex.
+Alternatively, if the critical section might call some of the
+usb_autopm_* routines, the driver can avoid deadlock by doing:
+
+	down(&udev->dev.sem);
+	rc = usb_autopm_get_interface(intf);
+
+and at the end of the critical section:
+
+	if (!rc)
+		usb_autopm_put_interface(intf);
+	up(&udev->dev.sem);
+
+Holding the device semaphore will block all external PM calls, and the
+usb_autopm_get_interface() will prevent any internal PM calls, even if
+it fails.  (Exercise: Why?)
+
+The rules for locking order are:
+
+	Never acquire any device semaphore while holding any PM mutex.
+
+	Never acquire udev->pm_mutex while holding the PM mutex for
+	a device that isn't a descendant of udev.
+
+In other words, PM mutexes should only be acquired going up the device
+tree, and they should be acquired only after locking all the device
+semaphores you need to hold.  These rules don't matter to drivers very
+much; they usually affect just the USB core.
+
+Still, drivers do need to be careful.  For example, many drivers use a
+private mutex to synchronize their normal I/O activities with their
+disconnect method.  Now if the driver supports autosuspend then it
+must call usb_autopm_put_interface() from somewhere -- maybe from its
+close method.  It should make the call while holding the private mutex,
+since a driver shouldn't call any of the usb_autopm_* functions for an
+interface from which it has been unbound.
+
+But the usb_autpm_* routines always acquire the device's PM mutex, and
+consequently the locking order has to be: private mutex first, PM
+mutex second.  Since the suspend method is always called with the PM
+mutex held, it mustn't try to acquire the private mutex.  It has to
+synchronize with the driver's I/O activities in some other way.
+
+
+	Interaction between dynamic PM and system PM
+	--------------------------------------------
+
+Dynamic power management and system power management can interact in
+a couple of ways.
+
+Firstly, a device may already be manually suspended or autosuspended
+when a system suspend occurs.  Since system suspends are supposed to
+be as transparent as possible, the device should remain suspended
+following the system resume.  The 2.6.23 kernel obeys this principle
+for manually suspended devices but not for autosuspended devices; they
+do get resumed when the system wakes up.  (Presumably they will be
+autosuspended again after their idle-delay time expires.)  In later
+kernels this behavior will be fixed.
+
+(There is an exception.  If a device would undergo a reset-resume
+instead of a normal resume, and the device is enabled for remote
+wakeup, then the reset-resume takes place even if the device was
+already suspended when the system suspend began.  The justification is
+that a reset-resume is a kind of remote-wakeup event.  Or to put it
+another way, a device which needs a reset won't be able to generate
+normal remote-wakeup signals, so it ought to be resumed immediately.)
+
+Secondly, a dynamic power-management event may occur as a system
+suspend is underway.  The window for this is short, since system
+suspends don't take long (a few seconds usually), but it can happen.
+For example, a suspended device may send a remote-wakeup signal while
+the system is suspending.  The remote wakeup may succeed, which would
+cause the system suspend to abort.  If the remote wakeup doesn't
+succeed, it may still remain active and thus cause the system to
+resume as soon as the system suspend is complete.  Or the remote
+wakeup may fail and get lost.  Which outcome occurs depends on timing
+and on the hardware and firmware design.
+
+More interestingly, a device might undergo a manual resume or
+autoresume during system suspend.  With current kernels this shouldn't
+happen, because manual resumes must be initiated by userspace and
+autoresumes happen in response to I/O requests, but all user processes
+and I/O should be quiescent during a system suspend -- thanks to the
+freezer.  However there are plans to do away with the freezer, which
+would mean these things would become possible.  If and when this comes
+about, the USB core will carefully arrange matters so that either type
+of resume will block until the entire system has resumed.

+ * After the handler is installed, an AML method can call native firmware by
+ * storing the arguments and firmware entry point to specific offsets in the
+ * OpRegion.  When AML reads the "return value" offset from the OpRegion, this
+ * handler loads up the arguments, makes the firmware call, and returns the
+ * result.

+	devices, like monitor controls and Uninterruptable Power Supplies.
+
+	This module supports these devices separately using a separate

+
+	There is also a /dev/hiddev configuration option in the USB HID
+	configuration menu. In comparison to hiddev, this device does not process
+	the hid events at all (no parsing, no lookups). This lets applications
+	to work on raw hid events when they want to, and avoid using transport-specific
+	userspace libhid/libusb libraries.
+

+ * drivers/mtd/maps/intel_vr_nor.c
+ *
+ * An MTD map driver for a NOR flash bank on the Expansion Bus of the Intel
+ * Vermilion Range chipset.
+ *
+ * The Vermilion Range Expansion Bus supports four chip selects, each of which
+ * has 64MiB of address space.  The 2nd BAR of the Expansion Bus PCI Device
+ * is a 256MiB memory region containing the address spaces for all four of the
+ * chip selects, with start addresses hardcoded on 64MiB boundaries.
+ *
+ * This map driver only supports NOR flash on chip select 0.  The buswidth
+ * (either 8 bits or 16 bits) is determined by reading the Expansion Bus Timing
+ * and Control Register for Chip Select 0 (EXP_TIMING_CS0).  This driver does
+ * not modify the value in the EXP_TIMING_CS0 register except to enable writing
+ * and disable boot acceleration.  The timing parameters in the register are
+ * assumed to have been properly initialized by the BIOS.  The reset default
+ * timing parameters are maximally conservative (slow), so access to the flash
+ * will be slower than it should be if the BIOS has not initialized the timing
+ * parameters.

-  A. Linux Kernels Supported by this Driver
-
-     This driver has been tested in the following Linux kernels: v2.2.18
-     v2.4.0. The driver is supported on v2.2 and v2.4 kernels and on x86,
-     alpha, and PowerPC platforms.
-
-  B. Adapters Supported by this Driver
-
-     AdvanSys (Advanced System Products, Inc.) manufactures the following
-     RISC-based, Bus-Mastering, Fast (10 Mhz) and Ultra (20 Mhz) Narrow
-     (8-bit transfer) SCSI Host Adapters for the ISA, EISA, VL, and PCI
-     buses and RISC-based, Bus-Mastering, Ultra (20 Mhz) Wide (16-bit
-     transfer) SCSI Host Adapters for the PCI bus.
-
-     The CDB counts below indicate the number of SCSI CDB (Command
-     Descriptor Block) requests that can be stored in the RISC chip
-     cache and board LRAM. A CDB is a single SCSI command. The driver
-     detect routine will display the number of CDBs available for each
-     adapter detected. The number of CDBs used by the driver can be
-     lowered in the BIOS by changing the 'Host Queue Size' adapter setting.

-  C. Linux source files modified by AdvanSys Driver
-
-     This section for historical purposes documents the changes
-     originally made to the Linux kernel source to add the advansys
-     driver. As Linux has changed some of these files have also
-     been modified.
-
-     1. linux/arch/i386/config.in:
-
-          bool 'AdvanSys SCSI support' CONFIG_SCSI_ADVANSYS y
-
-     2. linux/drivers/scsi/hosts.c:
-
-          #ifdef CONFIG_SCSI_ADVANSYS
-          #include "advansys.h"
-          #endif
-
-        and after "static struct scsi_host_template builtin_scsi_hosts[] =":
-
-          #ifdef CONFIG_SCSI_ADVANSYS
-          ADVANSYS,
-          #endif
-
-     3. linux/drivers/scsi/Makefile:
-
-          ifdef CONFIG_SCSI_ADVANSYS
-          SCSI_SRCS := $(SCSI_SRCS) advansys.c
-          SCSI_OBJS := $(SCSI_OBJS) advansys.o
-          else
-          SCSI_MODULE_OBJS := $(SCSI_MODULE_OBJS) advansys.o
-          endif
-
-     4. linux/init/main.c:
-
-          extern void advansys_setup(char *str, int *ints);
-
-        and add the following lines to the bootsetups[] array.
-
-          #ifdef CONFIG_SCSI_ADVANSYS
-             { "advansys=", advansys_setup },
-          #endif
-
-  D. Source Comments
-
-     1. Use tab stops set to 4 for the source files. For vi use 'se tabstops=4'.
-
-     2. This driver should be maintained in multiple files. But to make
-        it easier to include with Linux and to follow Linux conventions,
-        the whole driver is maintained in the source files advansys.h and
-        advansys.c. In this file logical sections of the driver begin with
-        a comment that contains '---'. The following are the logical sections
-        of the driver below.

-     3. The string 'XXX' is used to flag code that needs to be re-written
-        or that contains a problem that needs to be addressed.
-
-     4. I have stripped comments from and reformatted the source for the
-        Asc Library and Adv Library to reduce the size of this file. This
-        source can be found under the following headings. The Asc Library
-        is used to support Narrow Boards. The Adv Library is used to
-        support Wide Boards.

-  E. Driver Compile Time Options and Debugging
-
-     In this source file the following constants can be defined. They are
-     defined in the source below. Both of these options are enabled by
-     default.
-
-     1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled)
-
-        Enabling this option adds assertion logic statements to the
-        driver. If an assertion fails a message will be displayed to
-        the console, but the system will continue to operate. Any
-        assertions encountered should be reported to the person
-        responsible for the driver. Assertion statements may proactively
-        detect problems with the driver and facilitate fixing these
-        problems. Enabling assertions will add a small overhead to the
-        execution of the driver.
-
-     2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled)
-
-        Enabling this option adds tracing functions to the driver and
-        the ability to set a driver tracing level at boot time. This
-        option will also export symbols not required outside the driver to
-        the kernel name space. This option is very useful for debugging
-        the driver, but it will add to the size of the driver execution
-        image and add overhead to the execution of the driver.
-
-        The amount of debugging output can be controlled with the global
-        variable 'asc_dbglvl'. The higher the number the more output. By
-        default the debug level is 0.
-
-        If the driver is loaded at boot time and the LILO Driver Option
-        is included in the system, the debug level can be changed by
-        specifying a 5th (ASC_NUM_IOPORT_PROBE + 1) I/O Port. The
-        first three hex digits of the pseudo I/O Port must be set to
-        'deb' and the fourth hex digit specifies the debug level: 0 - F.
-        The following command line will look for an adapter at 0x330
-        and set the debug level to 2.
-
-           linux advansys=0x330,0,0,0,0xdeb2
-
-        If the driver is built as a loadable module this variable can be
-        defined when the driver is loaded. The following insmod command
-        will set the debug level to one.
-
-           insmod advansys.o asc_dbglvl=1
-
-        Debugging Message Levels:
-           0: Errors Only
-           1: High-Level Tracing
-           2-N: Verbose Tracing
-
-        To enable debug output to console, please make sure that:
-
-        a. System and kernel logging is enabled (syslogd, klogd running).
-        b. Kernel messages are routed to console output. Check
-           /etc/syslog.conf for an entry similar to this:
-
-                kern.*                  /dev/console
-
-        c. klogd is started with the appropriate -c parameter
-           (e.g. klogd -c 8)
-
-        This will cause printk() messages to be be displayed on the
-        current console. Refer to the klogd(8) and syslogd(8) man pages
-        for details.
-
-        Alternatively you can enable printk() to console with this
-        program. However, this is not the 'official' way to do this.
-        Debug output is logged in /var/log/messages.
-
-          main()
-          {
-                  syscall(103, 7, 0, 0);
-          }
-
-        Increasing LOG_BUF_LEN in kernel/printk.c to something like
-        40960 allows more debug messages to be buffered in the kernel
-        and written to the console or log file.
-
-     3. ADVANSYS_STATS - Enable statistics (Def: Enabled >= v1.3.0)
-
-        Enabling this option adds statistics collection and display
-        through /proc to the driver. The information is useful for
-        monitoring driver and device performance. It will add to the
-        size of the driver execution image and add minor overhead to
-        the execution of the driver.
-
-        Statistics are maintained on a per adapter basis. Driver entry
-        point call counts and transfer size counts are maintained.
-        Statistics are only available for kernels greater than or equal
-        to v1.3.0 with the CONFIG_PROC_FS (/proc) file system configured.
-
-        AdvanSys SCSI adapter files have the following path name format:
-
-           /proc/scsi/advansys/[0-(ASC_NUM_BOARD_SUPPORTED-1)]
-
-        This information can be displayed with cat. For example:
-
-           cat /proc/scsi/advansys/0
-
-        When ADVANSYS_STATS is not defined the AdvanSys /proc files only
-        contain adapter and device configuration information.
-
-  F. Driver LILO Option
-
-     If init/main.c is modified as described in the 'Directions for Adding
-     the AdvanSys Driver to Linux' section (B.4.) above, the driver will
-     recognize the 'advansys' LILO command line and /etc/lilo.conf option.
-     This option can be used to either disable I/O port scanning or to limit
-     scanning to 1 - 4 I/O ports. Regardless of the option setting EISA and
-     PCI boards will still be searched for and detected. This option only
-     affects searching for ISA and VL boards.
-
-     Examples:
-       1. Eliminate I/O port scanning:
-            boot: linux advansys=
-              or
-            boot: linux advansys=0x0
-       2. Limit I/O port scanning to one I/O port:
-            boot: linux advansys=0x110
-       3. Limit I/O port scanning to four I/O ports:
-            boot: linux advansys=0x110,0x210,0x230,0x330
-
-     For a loadable module the same effect can be achieved by setting
-     the 'asc_iopflag' variable and 'asc_ioport' array when loading
-     the driver, e.g.
-
-           insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330
-
-     If ADVANSYS_DEBUG is defined a 5th (ASC_NUM_IOPORT_PROBE + 1)
-     I/O Port may be added to specify the driver debug level. Refer to
-     the 'Driver Compile Time Options and Debugging' section above for
-     more information.
-
-  G. Tests to run before releasing new driver
-
-     1. In the supported kernels verify there are no warning or compile
-        errors when the kernel is built as both a driver and as a module
-        and with the following options:
-
-        ADVANSYS_DEBUG - enabled and disabled
-        CONFIG_SMP - enabled and disabled
-        CONFIG_PROC_FS - enabled and disabled
-
-     2. Run tests on an x86, alpha, and PowerPC with at least one narrow
-        card and one wide card attached to a hard disk and CD-ROM drive:
-        fdisk, mkfs, fsck, bonnie, copy/compare test from the
-        CD-ROM to the hard drive.
-
-  H. Release History

-         1. Prevent re-entrancy in the interrupt handler which
-            resulted in the driver hanging Linux.
-         2. Fix problem that prevented ABP-940 cards from being
-            recognized on some PCI motherboards.

-
-     1.3 (2/23/96):
-         1. Fix problem in advansys_biosparam() that resulted in the
-            wrong drive geometry being returned for drives > 1GB with
-            extended translation enabled.
-         2. Add additional tracing during device initialization.
-         3. Change code that only applies to ISA PnP adapter.
-         4. Eliminate 'make dep' warning.
-         5. Try to fix problem with handling resets by increasing their
-            timeout value.
-
-     1.4 (5/8/96):
-         1. Change definitions to eliminate conflicts with other subsystems.
-         2. Add versioning code for the shared interrupt changes.
-         3. Eliminate problem in asc_rmqueue() with iterating after removing
-            a request.
-         4. Remove reset request loop problem from the "Known Problems or
-            Issues" section. This problem was isolated and fixed in the
-            mid-level SCSI driver.
-
-     1.5 (8/8/96):
-         1. Add support for ABP-940U (PCI Ultra) adapter.
-         2. Add support for IRQ sharing by setting the IRQF_SHARED flag for
-            request_irq and supplying a dev_id pointer to both request_irq()
-            and free_irq().
-         3. In AscSearchIOPortAddr11() restore a call to check_region() which
-            should be used before I/O port probing.
-         4. Fix bug in asc_prt_hex() which resulted in the displaying
-            the wrong data.
-         5. Incorporate miscellaneous Asc Library bug fixes and new microcode.
-         6. Change driver versioning to be specific to each Linux sub-level.
-         7. Change statistics gathering to be per adapter instead of global
-            to the driver.
-         8. Add more information and statistics to the adapter /proc file:
-            /proc/scsi/advansys[0...].
-         9. Remove 'cmd_per_lun' from the "Known Problems or Issues" list.
-            This problem has been addressed with the SCSI mid-level changes
-            made in v1.3.89. The advansys_select_queue_depths() function
-            was added for the v1.3.89 changes.
-
-     1.6 (9/10/96):
-         1. Incorporate miscellaneous Asc Library bug fixes and new microcode.
-
-     1.7 (9/25/96):
-         1. Enable clustering and optimize the setting of the maximum number
-            of scatter gather elements for any particular board. Clustering
-            increases CPU utilization, but results in a relatively larger
-            increase in I/O throughput.
-         2. Improve the performance of the request queuing functions by
-            adding a last pointer to the queue structure.
-         3. Correct problems with reset and abort request handling that
-            could have hung or crashed Linux.
-         4. Add more information to the adapter /proc file:
-            /proc/scsi/advansys[0...].
-         5. Remove the request timeout issue form the driver issues list.
-         6. Miscellaneous documentation additions and changes.
-
-     1.8 (10/4/96):
-         1. Make changes to handle the new v2.1.0 kernel memory mapping
-            in which a kernel virtual address may not be equivalent to its
-            bus or DMA memory address.
-         2. Change abort and reset request handling to make it yet even
-            more robust.
-         3. Try to mitigate request starvation by sending ordered requests
-            to heavily loaded, tag queuing enabled devices.
-         4. Maintain statistics on request response time.
-         5. Add request response time statistics and other information to
-            the adapter /proc file: /proc/scsi/advansys[0...].
-
-     1.9 (10/21/96):
-         1. Add conditionally compiled code (ASC_QUEUE_FLOW_CONTROL) to
-            make use of mid-level SCSI driver device queue depth flow
-            control mechanism. This will eliminate aborts caused by a
-            device being unable to keep up with requests and eliminate
-            repeat busy or QUEUE FULL status returned by a device.
-         2. Incorporate miscellaneous Asc Library bug fixes.
-         3. To allow the driver to work in kernels with broken module
-            support set 'cmd_per_lun' if the driver is compiled as a
-            module. This change affects kernels v1.3.89 to present.
-         4. Remove PCI BIOS address from the driver banner. The PCI BIOS
-            is relocated by the motherboard BIOS and its new address can
-            not be determined by the driver.
-         5. Add mid-level SCSI queue depth information to the adapter
-            /proc file: /proc/scsi/advansys[0...].
-
-     2.0 (11/14/96):
-         1. Change allocation of global structures used for device
-            initialization to guarantee they are in DMA-able memory.
-            Previously when the driver was loaded as a module these
-            structures might not have been in DMA-able memory, causing
-            device initialization to fail.
-
-     2.1 (12/30/96):
-         1. In advansys_reset(), if the request is a synchronous reset
-            request, even if the request serial number has changed, then
-            complete the request.
-         2. Add Asc Library bug fixes including new microcode.
-         3. Clear inquiry buffer before using it.
-         4. Correct ifdef typo.
-
-     2.2 (1/15/97):
-         1. Add Asc Library bug fixes including new microcode.
-         2. Add synchronous data transfer rate information to the
-            adapter /proc file: /proc/scsi/advansys[0...].
-         3. Change ADVANSYS_DEBUG to be disabled by default. This
-            will reduce the size of the driver image, eliminate execution
-            overhead, and remove unneeded symbols from the kernel symbol
-            space that were previously added by the driver.
-         4. Add new compile-time option ADVANSYS_ASSERT for assertion
-            code that used to be defined within ADVANSYS_DEBUG. This
-            option is enabled by default.
-
-     2.8 (5/26/97):
-         1. Change version number to 2.8 to synchronize the Linux driver
-            version numbering with other AdvanSys drivers.
-         2. Reformat source files without tabs to present the same view
-            of the file to everyone regardless of the editor tab setting
-            being used.
-         3. Add Asc Library bug fixes.
-
-     3.1A (1/8/98):
-         1. Change version number to 3.1 to indicate that support for
-            Ultra-Wide adapters (ABP-940UW) is included in this release.
-         2. Add Asc Library (Narrow Board) bug fixes.
-         3. Report an underrun condition with the host status byte set
-            to DID_UNDERRUN. Currently DID_UNDERRUN is defined to 0 which
-            causes the underrun condition to be ignored. When Linux defines
-            its own DID_UNDERRUN the constant defined in this file can be
-            removed.
-         4. Add patch to AscWaitTixISRDone().
-         5. Add support for up to 16 different AdvanSys host adapter SCSI
-            channels in one system. This allows four cards with four channels
-            to be used in one system.
-
-     3.1B (1/9/98):
-         1. Handle that PCI register base addresses are not always page
-            aligned even though ioremap() requires that the address argument
-            be page aligned.
-
-     3.1C (1/10/98):
-         1. Update latest BIOS version checked for from the /proc file.
-         2. Don't set microcode SDTR variable at initialization. Instead
-            wait until device capabilities have been detected from an Inquiry
-            command.
-
-     3.1D (1/21/98):
-         1. Improve performance when the driver is compiled as module by
-            allowing up to 64 scatter-gather elements instead of 8.
-
-     3.1E (5/1/98):
-         1. Set time delay in AscWaitTixISRDone() to 1000 ms.
-         2. Include SMP locking changes.
-         3. For v2.1.93 and newer kernels use CONFIG_PCI and new PCI BIOS
-            access functions.
-         4. Update board serial number printing.
-         5. Try allocating an IRQ both with and without the IRQF_DISABLED
-            flag set to allow IRQ sharing with drivers that do not set
-            the IRQF_DISABLED flag. Also display a more descriptive error
-            message if request_irq() fails.
-         6. Update to latest Asc and Adv Libraries.
-
-     3.2A (7/22/99):
-         1. Update Adv Library to 4.16 which includes support for
-            the ASC38C0800 (Ultra2/LVD) IC.
-
-     3.2B (8/23/99):
-         1. Correct PCI compile time option for v2.1.93 and greater
-            kernels, advansys_info() string, and debug compile time
-            option.
-         2. Correct DvcSleepMilliSecond() for v2.1.0 and greater
-            kernels. This caused an LVD detection/BIST problem problem
-            among other things.
-         3. Sort PCI cards by PCI Bus, Slot, Function ascending order
-            to be consistent with the BIOS.
-         4. Update to Asc Library S121 and Adv Library 5.2.
-
-     3.2C (8/24/99):
-         1. Correct PCI card detection bug introduced in 3.2B that
-            prevented PCI cards from being detected in kernels older
-            than v2.1.93.
-
-     3.2D (8/26/99):
-         1. Correct /proc device synchronous speed information display.
-            Also when re-negotiation is pending for a target device
-            note this condition with an * and footnote.
-         2. Correct initialization problem with Ultra-Wide cards that
-            have a pre-3.2 BIOS. A microcode variable changed locations
-            in 3.2 and greater BIOSes which caused WDTR to be attempted
-            erroneously with drives that don't support WDTR.
-
-     3.2E (8/30/99):
-         1. Fix compile error caused by v2.3.13 PCI structure change.
-         2. Remove field from ASCEEP_CONFIG that resulted in an EEPROM
-            checksum error for ISA cards.
-         3. Remove ASC_QUEUE_FLOW_CONTROL conditional code. The mid-level
-            SCSI changes that it depended on were never included in Linux.
-
-     3.2F (9/3/99):
-         1. Handle new initial function code added in v2.3.16 for all
-            driver versions.
-
-     3.2G (9/8/99):
-         1. Fix PCI board detection in v2.3.13 and greater kernels.
-         2. Fix comiple errors in v2.3.X with debugging enabled.
-
-     3.2H (9/13/99):
-         1. Add 64-bit address, long support for Alpha and UltraSPARC.
-            The driver has been verified to work on an Alpha system.
-         2. Add partial byte order handling support for Power PC and
-            other big-endian platforms. This support has not yet been
-            completed or verified.
-         3. For wide boards replace block zeroing of request and
-            scatter-gather structures with individual field initialization
-            to improve performance.
-         4. Correct and clarify ROM BIOS version detection.
-
-     3.2I (10/8/99):
-         1. Update to Adv Library 5.4.
-         2. Add v2.3.19 underrun reporting to asc_isr_callback() and
-            adv_isr_callback().  Remove DID_UNDERRUN constant and other
-            no longer needed code that previously documented the lack
-            of underrun handling.
-
-     3.2J (10/14/99):
-         1. Eliminate compile errors for v2.0 and earlier kernels.
-
-     3.2K (11/15/99):
-         1. Correct debug compile error in asc_prt_adv_scsi_req_q().
-         2. Update Adv Library to 5.5.
-         3. Add ifdef handling for /proc changes added in v2.3.28.
-         4. Increase Wide board scatter-gather list maximum length to
-            255 when the driver is compiled into the kernel.
-
-     3.2L (11/18/99):
-         1. Fix bug in adv_get_sglist() that caused an assertion failure
-            at line 7475. The reqp->sgblkp pointer must be initialized
-            to NULL in adv_get_sglist().
-
-     3.2M (11/29/99):
-         1. Really fix bug in adv_get_sglist().
-         2. Incorporate v2.3.29 changes into driver.
-
-     3.2N (4/1/00):
-         1. Add CONFIG_ISA ifdef code.
-         2. Include advansys_interrupts_enabled name change patch.
-         3. For >= v2.3.28 use new SCSI error handling with new function
-            advansys_eh_bus_reset(). Don't include an abort function
-            because of base library limitations.
-         4. For >= v2.3.28 use per board lock instead of io_request_lock.
-         5. For >= v2.3.28 eliminate advansys_command() and
-            advansys_command_done().
-         6. Add some changes for PowerPC (Big Endian) support, but it isn't
-            working yet.
-         7. Fix "nonexistent resource free" problem that occurred on a module
-            unload for boards with an I/O space >= 255. The 'n_io_port' field
-            is only one byte and can not be used to hold an ioport length more
-            than 255.
-
-     3.3A (4/4/00):
-         1. Update to Adv Library 5.8.
-         2. For wide cards add support for CDBs up to 16 bytes.
-         3. Eliminate warnings when CONFIG_PROC_FS is not defined.
-
-     3.3B (5/1/00):
-         1. Support for PowerPC (Big Endian) wide cards. Narrow cards
-            still need work.
-         2. Change bitfields to shift and mask access for endian
-            portability.
-
-     3.3C (10/13/00):
-         1. Update for latest 2.4 kernel.
-         2. Test ABP-480 CardBus support in 2.4 kernel - works!
-         3. Update to Asc Library S123.
-         4. Update to Adv Library 5.12.
-
-     3.3D (11/22/00):
-         1. Update for latest 2.4 kernel.
-         2. Create patches for 2.2 and 2.4 kernels.
-
-     3.3E (1/9/01):
-         1. Now that 2.4 is released remove ifdef code for kernel versions
-            less than 2.2. The driver is now only supported in kernels 2.2,
-            2.4, and greater.
-         2. Add code to release and acquire the io_request_lock in
-            the driver entrypoint functions: advansys_detect and
-            advansys_queuecommand. In kernel 2.4 the SCSI mid-level driver
-            still holds the io_request_lock on entry to SCSI low-level drivers.
-            This was supposed to be removed before 2.4 was released but never
-            happened. When the mid-level SCSI driver is changed all references
-            to the io_request_lock should be removed from the driver.
-         3. Simplify error handling by removing advansys_abort(),
-            AscAbortSRB(), AscResetDevice(). SCSI bus reset requests are
-            now handled by resetting the SCSI bus and fully re-initializing
-            the chip. This simple method of error recovery has proven to work
-            most reliably after attempts at different methods. Also now only
-            support the "new" error handling method and remove the obsolete
-            error handling interface.
-         4. Fix debug build errors.
-
-     3.3F (1/24/01):
-         1. Merge with ConnectCom version from Andy Kellner which
-            updates Adv Library to 5.14.
-         2. Make PowerPC (Big Endian) work for narrow cards and
-            fix problems writing EEPROM for wide cards.
-         3. Remove interrupts_enabled assertion function.
-
-     3.3G (2/16/01):
-         1. Return an error from narrow boards if passed a 16 byte
-            CDB. The wide board can already handle 16 byte CDBs.
-
-     3.3GJ (4/15/02):
-	 1. hacks for lk 2.5 series (D. Gilbert)
-
-     3.3GJD (10/14/02):
-         1. change select_queue_depths to slave_configure
-	 2. make cmd_per_lun be sane again
-
-     3.3K [2004/06/24]:
-         1. continuing cleanup for lk 2.6 series
-         2. Fix problem in lk 2.6.7-bk2 that broke PCI wide cards
-         3. Fix problem that oopsed ISA cards
-
-  I. Known Problems/Fix List (XXX)
-
-     1. Need to add memory mapping workaround. Test the memory mapping.
-        If it doesn't work revert to I/O port access. Can a test be done
-        safely?
-     2. Handle an interrupt not working. Keep an interrupt counter in
-        the interrupt handler. In the timeout function if the interrupt
-        has not occurred then print a message and run in polled mode.
-     3. Allow bus type scanning order to be changed.
-     4. Need to add support for target mode commands, cf. CAM XPT.

 	  happen is unclear however so it is worth waiting until someone hits
 	  the problem.
 
+2.1.29 - Fix a deadlock at mount time.
+
+	- During mount the VFS holds s_umount lock on the superblock.  So when
+	  we try to empty the journal $LogFile contents by calling
+	  ntfs_attr_set() when the machine does not have much memory and the
+	  journal is large ntfs_attr_set() results in the VM trying to balance
+	  dirty pages which in turn tries to that the s_umount lock and thus we
+	  get a deadlock.  The solution is to not use ntfs_attr_set() and
+	  instead do the zeroing by hand at the block level rather than page
+	  cache level.
+	- Fix sparse warnings.
+
 2.1.28 - Fix a deadlock.
 
 	- Fix deadlock in fs/ntfs/inode.c::ntfs_put_inode().  Thanks to Sergey

- * I2C Message - used for pure i2c transaction, also from /dev interface
+/**
+ * struct i2c_msg - an I2C transaction segment beginning with START
+ * @addr: Slave address, either seven or ten bits.  When this is a ten
+ *	bit address, I2C_M_TEN must be set in @flags and the adapter
+ *	must support I2C_FUNC_10BIT_ADDR.
+ * @flags: I2C_M_RD is handled by all adapters.  No other flags may be
+ *	provided unless the adapter exported the relevant I2C_FUNC_*
+ *	flags through i2c_check_functionality().
+ * @len: Number of data bytes in @buf being read from or written to the
+ *	I2C slave address.  For read transactions where I2C_M_RECV_LEN
+ *	is set, the caller guarantees that this buffer can hold up to
+ *	32 bytes in addition to the initial length byte sent by the
+ *	slave (plus, if used, the SMBus PEC); and this value will be
+ *	incremented by the number of block data bytes received.
+ * @buf: The buffer into which data is read, or from which it's written.
+ *
+ * An i2c_msg is the low level representation of one segment of an I2C
+ * transaction.  It is visible to drivers in the @i2c_transfer() procedure,
+ * to userspace from i2c-dev, and to I2C adapter drivers through the
+ * @i2c_adapter.@master_xfer() method.
+ *
+ * Except when I2C "protocol mangling" is used, all I2C adapters implement
+ * the standard rules for I2C transactions.  Each transaction begins with a
+ * START.  That is followed by the slave address, and a bit encoding read
+ * versus write.  Then follow all the data bytes, possibly including a byte
+ * with SMBus PEC.  The transfer terminates with a NAK, or when all those
+ * bytes have been transferred and ACKed.  If this is the last message in a
+ * group, it is followed by a STOP.  Otherwise it is followed by the next
+ * @i2c_msg transaction segment, beginning with a (repeated) START.
+ *
+ * Alternatively, when the adapter supports I2C_FUNC_PROTOCOL_MANGLING then
+ * passing certain @flags may have changed those standard protocol behaviors.
+ * Those flags are only for use with broken/nonconforming slaves, and with
+ * adapters which are known to support the specific mangling options they
+ * need (one or more of IGNORE_NAK, NO_RD_ACK, NOSTART, and REV_DIR_ADDR).
