will fail enabling MSI-X on its hardware device when it calls the function
pci_enable_msix().
-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
- table entries (2048 max) to mask/unmask any match vector
- is an undesirable solution.
-
- - Walking through all MSI-X table entries (2048 max) to handle
- SMP affinity of any match vector is an undesirable solution.

+
+uvesafb - A Generic Driver for VBE2+ compliant video cards
+==========================================================
+
+1. Requirements
+---------------
+
+uvesafb should work with any video card that has a Video BIOS compliant
+with the VBE 2.0 standard.
+
+Unlike other drivers, uvesafb makes use of a userspace helper called
+v86d. v86d is used to run the x86 Video BIOS code in a simulated and
+controlled environment. This allows uvesafb to function on arches other
+than x86. Check the v86d documentation for a list of currently supported
+arches.
+
+v86d source code can be downloaded from the following website:
+ http://dev.gentoo.org/~spock/projects/uvesafb
+
+Please refer to the v86d documentation for detailed configuration and
+installation instructions.
+
+Note that the v86d userspace helper has to be available at all times in
+order for uvesafb to work properly. If you want to use uvesafb during
+early boot, you will have to include v86d into an initramfs image, and
+either compile it into the kernel or use it as an initrd.
+
+2. Caveats and limitations
+--------------------------
+
+uvesafb is a _generic_ driver which supports a wide variety of video
+cards, but which is ultimately limited by the Video BIOS interface.
+The most important limitations are:
+
+- Lack of any type of acceleration.
+- A strict and limited set of supported video modes. Often the native
+ or most optimal resolution/refresh rate for your setup will not work
+ with uvesafb, simply because the Video BIOS doesn't support the
+ video mode you want to use. This can be especially painful with
+ widescreen panels, where native video modes don't have the 4:3 aspect
+ ratio, which is what most BIOS-es are limited to.
+- Adjusting the refresh rate is only possible with a VBE 3.0 compliant
+ Video BIOS. Note that many nVidia Video BIOS-es claim to be VBE 3.0
+ compliant, while they simply ignore any refresh rate settings.
+
+3. Configuration
+----------------
+
+uvesafb can be compiled either as a module, or directly into the kernel.
+In both cases it supports the same set of configuration options, which
+are either given on the kernel command line or as module parameters, e.g.:
+
+ video=uvesafb:1024x768-32,mtrr:3,ywrap (compiled into the kernel)
+
+ # modprobe uvesafb mode=1024x768-32 mtrr=3 scroll=ywrap (module)
+
+Accepted options:
+
+ypan Enable display panning using the VESA protected mode
+ interface. The visible screen is just a window of the
+ video memory, console scrolling is done by changing the
+ start of the window. Available on x86 only.
+
+ywrap Same as ypan, but assumes your gfx board can wrap-around
+ the video memory (i.e. starts reading from top if it
+ reaches the end of video memory). Faster than ypan.
+ Available on x86 only.
+
+redraw Scroll by redrawing the affected part of the screen, this
+ is the safe (and slow) default.
+
+(If you're using uvesafb as a module, the above three options are
+ used a parameter of the scroll option, e.g. scroll=ypan.)
+
+vgapal Use the standard VGA registers for palette changes.
+
+pmipal Use the protected mode interface for palette changes.
+ This is the default if the protected mode interface is
+ available. Available on x86 only.
+
+mtrr:n Setup memory type range registers for the framebuffer
+ where n:
+ 0 - disabled (equivalent to nomtrr) (default)
+ 1 - uncachable
+ 2 - write-back
+ 3 - write-combining
+ 4 - write-through
+
+ If you see the following in dmesg, choose the type that matches
+ the old one. In this example, use "mtrr:2".
+...
+mtrr: type mismatch for e0000000,8000000 old: write-back new: write-combining
+...
+
+nomtrr Do not use memory type range registers.
+
+vremap:n
+ Remap 'n' MiB of video RAM. If 0 or not specified, remap memory
+ according to video mode.
+
+vtotal:n
+ If the video BIOS of your card incorrectly determines the total
+ amount of video RAM, use this option to override the BIOS (in MiB).
+
+<mode> The mode you want to set, in the standard modedb format. Refer to
+ modedb.txt for a detailed description. When uvesafb is compiled as
+ a module, the mode string should be provided as a value of the
+ 'mode' option.
+
+vbemode:x
+ Force the use of VBE mode x. The mode will only be set if it's
+ found in the VBE-provided list of supported modes.
+ NOTE: The mode number 'x' should be specified in VESA mode number
+ notation, not the Linux kernel one (eg. 257 instead of 769).
+ HINT: If you use this option because normal <mode> parameter does
+ not work for you and you use a X server, you'll probably want to
+ set the 'nocrtc' option to ensure that the video mode is properly
+ restored after console <-> X switches.
+
+nocrtc Do not use CRTC timings while setting the video mode. This option
+ has any effect only if the Video BIOS is VBE 3.0 compliant. Use it
+ if you have problems with modes set the standard way. Note that
+ using this option implies that any refresh rate adjustments will
+ be ignored and the refresh rate will stay at your BIOS default (60 Hz).
+
+noedid Do not try to fetch and use EDID-provided modes.
+
+noblank Disable hardware blanking.
+
+v86d:path
+ Set path to the v86d executable. This option is only available as
+ a module parameter, and not as a part of the video= string. If you
+ need to use it and have uvesafb built into the kernel, use
+ uvesafb.v86d="path".
+
+Additionally, the following parameters may be provided. They all override the
+EDID-provided values and BIOS defaults. Refer to your monitor's specs to get
+the correct values for maxhf, maxvf and maxclk for your hardware.
+
+maxhf:n Maximum horizontal frequency (in kHz).
+maxvf:n Maximum vertical frequency (in Hz).
+maxclk:n Maximum pixel clock (in MHz).
+
+4. The sysfs interface
+----------------------
+
+uvesafb provides several sysfs nodes for configurable parameters and
+additional information.
+
+Driver attributes:
+
+/sys/bus/platform/drivers/uvesafb
+ - v86d (default: /sbin/v86d)
+ Path to the v86d executable. v86d is started by uvesafb
+ if an instance of the daemon isn't already running.
+
+Device attributes:
+
+/sys/bus/platform/drivers/uvesafb/uvesafb.0
+ - nocrtc
+ Use the default refresh rate (60 Hz) if set to 1.
+
+ - oem_product_name
+ - oem_product_rev
+ - oem_string
+ - oem_vendor
+ Information about the card and its maker.
+
+ - vbe_modes
+ A list of video modes supported by the Video BIOS along with their
+ VBE mode numbers in hex.
+
+ - vbe_version
+ A BCD value indicating the implemented VBE standard.
+
+5. Miscellaneous
+----------------
+
+Uvesafb will set a video mode with the default refresh rate and timings
+from the Video BIOS if you set pixclock to 0 in fb_var_screeninfo.

+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.

+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);
-pec Enable or disable PEC (SMBus only)

+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.

+fail_over_mac
+
+ Specifies whether active-backup mode should set all slaves to
+ the same MAC address (the traditional behavior), or, when
+ enabled, change the bond's MAC address when changing the
+ active interface (i.e., fail over the MAC address itself).
+
+ Fail over MAC is useful for devices that cannot ever alter
+ their MAC address, or for devices that refuse incoming
+ broadcasts with their own source MAC (which interferes with
+ the ARP monitor).
+
+ The down side of fail over MAC is that every device on the
+ network must be updated via gratuitous ARP, vs. just updating
+ a switch or set of switches (which often takes place for any
+ 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,
+ devices which assert link up prior to being able to actually
+ transmit and receive are particularly susecptible to loss of
+ the gratuitous ARP, and an appropriate updelay setting may be
+ required.
+
+ A value of 0 disables fail over MAC, and is the default. A
+ value of 1 enables fail over MAC. This option is enabled
+ automatically if the first slave added cannot change its MAC
+ address. This option may be modified via sysfs only when no
+ slaves are present in the bond.
+
+ This option was added in bonding version 3.2.0.

iterators of the scheduling modules are used. The balancing code got
quite a bit simpler as a result.
+
+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.

+Notes on Power-Saving Mode
+==========================
+
+AC97 and HD-audio drivers have the automatic power-saving mode.
+This feature is enabled via Kconfig CONFIG_SND_AC97_POWER_SAVE
+and CONFIG_SND_HDA_POWER_SAVE options, respectively.
+
+With the automatic power-saving, the driver turns off the codec power
+appropriately when no operation is required. When no applications use
+the device and/or no analog loopback is set, the power disablement is
+done fully or partially. It'll save a certain power consumption, thus
+good for laptops (even for desktops).
+
+The time-out for automatic power-off can be specified via power_save
+module option of snd-ac97-codec and snd-hda-intel modules. Specify
+the time-out value in seconds. 0 means to disable the automatic
+power-saving. The default value of timeout is given via
+CONFIG_SND_AC97_POWER_SAVE_DEFAULT and
+CONFIG_SND_HDA_POWER_SAVE_DEFAULT Kconfig options. Setting this to 1
+(the minimum value) isn't recommended because many applications try to
+reopen the device frequently. 10 would be a good choice for normal
+operations.
+
+The power_save option is exported as writable. This means you can
+adjust the value via sysfs on the fly. For example, to turn on the
+automatic power-save mode with 10 seconds, write to
+/sys/modules/snd_ac97_codec/parameters/power_save (usually as root):
+
+ # echo 10 > /sys/modules/snd_ac97_codec/parameters/power_save
+
+
+Note that you might hear click noise/pop when changing the power
+state. Also, it often takes certain time to wake up from the
+power-down to the active state. These are often hardly to fix, so
+don't report extra bug reports unless you have a fix patch ;-)
+
+For HD-audio interface, there is another module option,
+power_save_controller. This enables/disables the power-save mode of
+the controller side. Setting this on may reduce a bit more power
+consumption, but might result in longer wake-up time and click noise.
+Try to turn it off when you experience such a thing too often.

+
+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.
+
+ power/wakeup
+
+ 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.

- Selecting this option will support Silicon Motion, Inc. SM501.
- Designed to complement needs for the embedded industry, it
- provides video and 2D capability. To reduce system cost a
- wide variety of include I/O is supported, including analog RGB
- and digital LCD Panel interface, 8-bit parallel interface, USB,
- UART, IrDA, Zoom Video, AC97 or I2S, SSP, PWM, and I2C. There
- are additional GPIO bits that can be used to interface to
- external as well.

+
+ This module supports these devices separately using a separate
+ event interface on /dev/hidraw.
+
+ 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.
+
+ If unsure, say Y.

help
This supports the use of the I2C interface on Atmel AT91
processors.
+ This driver is BROKEN because the controller which it uses
+ will easily trigger RX overrun and TX underrun errors. Using
+ low I2C clock rates may partially work around those issues
+ on some systems. Another serious problem is that there is no
+ documented way to issue repeated START conditions, as needed
+ to support combined I2C messages. Use the i2c-gpio driver

- There are unclear terms in ATA-4 and ATA-5 standards how certain

- of the standards have been released in hardware. This causes problems:
- for example, a host with Ultra Mode 4 (or higher) will not run

- If you are experiencing compatibility or performance problems, you
- MAY try to answer Y here. However, it does not necessarily solve
- any of your problems, it could even cause more of them.
-
- It is normally safe to answer Y; however, the default is N.

+ * 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.

+ The 2X Program is an extension of Program Operation.
+ Since the device is equipped with two DataRAMs, and two-plane NAND
+ Flash memory array, these two component enables simultaneous program
+ of 4KiB. Plane1 has only even blocks such as block0, block2, block4
+ while Plane2 has only odd blocks such as block1, block3, block5.
+ So MTD regards it as 4KiB page size and 256KiB block size
+
+ Now the following chips support it. (KFXXX16Q2M)
+ Demux: KFG2G16Q2M, KFH4G16Q2M, KFW8G16Q2M,

- 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.
-
- --- Asc Library Constants and Macros
- --- Adv Library Constants and Macros
- --- Asc Library Functions
- --- Adv Library Functions
-
- 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
-
- BETA-1.0 (12/23/95):
- First Release
-
- BETA-1.1 (12/28/95):
- 1. Prevent advansys_detect() from being called twice.
- 2. Add LILO 0xdeb[0-f] option to set 'asc_dbglvl'.
-
- 1.2 (1/12/96):
- 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.
- 3. Add support for the ABP-5140 PnP ISA card.
- 4. Fix check condition return status.
- 5. Add conditionally compiled code for Linux v1.3.X.
-
- 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.

- 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

- 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

+ * 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).

- * Calculate the preemption granularity needed to schedule every

- * (down to a sensible low limit on granularity)
- *
- * For example, if there are 2 tasks running and latency is 10 msecs,
- * we switch tasks every 5 msecs. If we have 3 tasks running, we have
- * to switch tasks every 3.33 msecs to get a 10 msecs observed latency

- *
- * To achieve this we use the following dynamic-granularity rule:
- *
- * gran = lat/nr - lat/nr/nr
- *
- * This comes out of the following equations:
- *
- * kA1 + gran = kB1
- * kB2 + gran = kA2
- * kA2 = kA1
- * kB2 = kB1 - d + d/nr
- * lat = d * nr
- *
- * Where 'k' is key, 'A' is task A (waiting), 'B' is task B (running),
- * '1' is start of time, '2' is end of time, 'd' is delay between
- * 1 and 2 (during which task B was running), 'nr' is number of tasks

+ help
+ This build option allows you to read kernel boot messages
+ by inserting a short delay after each one. The delay is
+ specified in milliseconds on the kernel command line,
+ using "boot_delay=N".
+
+ It is likely that you would also need to use "lpj=M" to preset
+ the "loops per jiffie" value.
+ See a previous boot log for the "lpj" value to use for your
+ system, and then set "lpj=M" before setting "boot_delay=N".
+ NOTE: Using this option may adversely affect SMP systems.
+ I.e., processors other than the first one may not boot up.
+ BOOT_PRINTK_DELAY also may cause DETECT_SOFTLOCKUP to detect
+ what it believes to be lockup conditions.

+ * Virtual memory maps allow VM primitives pfn_to_page, page_to_pfn,
+ * virt_to_page, page_address() to be implemented as a base offset
+ * calculation without memory access.
+ *
+ * However, virtual mappings need a page table and TLBs. Many Linux
+ * architectures already map their physical space using 1-1 mappings
+ * via TLBs. For those arches the virtual memmory map is essentially
+ * for free if we use the same page size as the 1-1 mappings. In that
+ * case the overhead consists of a few additional pages that are
+ * allocated to create a view of memory for vmemmap.
+ *
+ * The architecture is expected to provide a vmemmap_populate() function
+ * to instantiate the mapping.

+ * 3) Only Master mode is supported, not Slave.
+ * 4) The machine driver's 'startup' function must call
+ * cs4270_set_dai_sysclk() with the value of MCLK.
+ * 5) Only I2S and left-justified modes are supported
+ * 6) Power management is not supported
+ * 7) The only supported control is volume and hardware mute (if enabled)
