+Description:
+                Writing a device ID to this file will remove an ID
+                that was dynamically added via the new_id sysfs entry.
+                The format for the device ID is:
+                idVendor idProduct.     After successfully
+                removing an ID, the driver will no longer support the
+                device.  This is useful to ensure auto probing won't

-      when Jeff Garzik explained the use of procfs and forwarded me a

-      The <filename class="directory">/proc</filename> file system
-      (procfs) is a special file system in the linux kernel. It's a
-      virtual file system: it is not associated with a block device
-      but exists only in memory. The files in the procfs are there to
-      allow userland programs access to certain information from the
-      kernel (like process information in <filename
-      class="directory">/proc/[0-9]+/</filename>), but also for debug
-      purposes (like <filename>/proc/ksyms</filename>).
-    </para>
-    <para>
-      This guide describes the use of the procfs file system from
-      within the Linux kernel. It starts by introducing all relevant
-      functions to manage the files within the file system. After that
-      it shows how to communicate with userland, and some tips and
-      tricks will be pointed out. Finally a complete example will be
-      shown.
-    </para>
-    <para>
-      Note that the files in <filename
-      class="directory">/proc/sys</filename> are sysctl files: they
-      don't belong to procfs and are governed by a completely
-      different API described in the Kernel API book.

-      A minor note before we start: if you want to use any of the

-         function that distinguishes between the files by using the
-         <structfield>data</structfield> field in <structname>struct
-         proc_dir_entry</structname>. First of all, the
-         <structfield>data</structfield> field has to be initialised:
-      </para>
-      <programlisting>
-struct proc_dir_entry* entry;
-struct my_file_data *file_data;
-file_data = kmalloc(sizeof(struct my_file_data), GFP_KERNEL);
-entry->data = file_data;
-      </programlisting>
-     
-      <para>
-          The <structfield>data</structfield> field is a <type>void
-          *</type>, so it can be initialised with anything.
-      </para>
-      <para>
-        Now that the <structfield>data</structfield> field is set, the
-        <function>read_proc</function> and
-        <function>write_proc</function> can use it to distinguish
-        between files because they get it passed into their
-        <parameter>data</parameter> parameter:
-      </para>
-      <programlisting>
-int foo_read_func(char *page, char **start, off_t off,
-                  int count, int *eof, void *data)
-{
-        int len;
-        if(data == file_data) {
-                /* special case for this file */
-        } else {
-                /* normal processing */
-        }
-        return len;
-}
-      </programlisting>
-      <para>
-        Be sure to free the <structfield>data</structfield> data field
-        when removing the procfs entry.

-The following sections describe the debugfs files and formats for
-preemptable RCU (rcupreempt) and hierarchical RCU (rcutree).
-Preemptable RCU debugfs Files and Formats
-This implementation of RCU provides three debugfs files under the
-top-level directory RCU: rcu/rcuctrs (which displays the per-CPU
-counters used by preemptable RCU) rcu/rcugp (which displays grace-period
-counters), and rcu/rcustats (which internal counters for debugging RCU).
-The output of "cat rcu/rcuctrs" looks as follows:
-CPU last cur F M
-  0    5  -5 0 0
-  1   -1   0 0 0
-  2    0   1 0 0
-  3    0   1 0 0
-  4    0   1 0 0
-  5    0   1 0 0
-  6    0   2 0 0
-  7    0  -1 0 0
-  8    0   1 0 0
-ggp = 26226, state = waitzero
-The per-CPU fields are as follows:
-o       "CPU" gives the CPU number.  Offline CPUs are not displayed.
-o       "last" gives the value of the counter that is being decremented
-        for the current grace period phase.  In the example above,
-        the counters sum to 4, indicating that there are still four
-        RCU read-side critical sections still running that started
-        before the last counter flip.
-o       "cur" gives the value of the counter that is currently being
-        both incremented (by rcu_read_lock()) and decremented (by
-        rcu_read_unlock()).  In the example above, the counters sum to
-        1, indicating that there is only one RCU read-side critical section
-        still running that started after the last counter flip.
-o       "F" indicates whether RCU is waiting for this CPU to acknowledge
-        a counter flip.  In the above example, RCU is not waiting on any,
-        which is consistent with the state being "waitzero" rather than
-        "waitack".
-o       "M" indicates whether RCU is waiting for this CPU to execute a
-        memory barrier.  In the above example, RCU is not waiting on any,
-        which is consistent with the state being "waitzero" rather than
-        "waitmb".
-o       "ggp" is the global grace-period counter.
-o       "state" is the RCU state, which can be one of the following:
-        o       "idle": there is no grace period in progress.
-        o       "waitack": RCU just incremented the global grace-period
-                counter, which has the effect of reversing the roles of
-                the "last" and "cur" counters above, and is waiting for
-                all the CPUs to acknowledge the flip.  Once the flip has
-                been acknowledged, CPUs will no longer be incrementing
-                what are now the "last" counters, so that their sum will
-                decrease monotonically down to zero.
-        o       "waitzero": RCU is waiting for the sum of the "last" counters
-                to decrease to zero.
-        o       "waitmb": RCU is waiting for each CPU to execute a memory
-                barrier, which ensures that instructions from a given CPU's
-                last RCU read-side critical section cannot be reordered
-                with instructions following the memory-barrier instruction.
-The output of "cat rcu/rcugp" looks as follows:
-oldggp=48870  newggp=48873
-Note that reading from this file provokes a synchronize_rcu().  The
-"oldggp" value is that of "ggp" from rcu/rcuctrs above, taken before
-executing the synchronize_rcu(), and the "newggp" value is also the
-"ggp" value, but taken after the synchronize_rcu() command returns.
-The output of "cat rcu/rcugp" looks as follows:

-callbacks in various states.  The fields are as follows:
-o       "na" is the total number of RCU callbacks that have been enqueued
-        since boot.
-o       "nl" is the number of RCU callbacks waiting for the previous
-        grace period to end so that they can start waiting on the next
-        grace period.
-o       "wa" is the total number of RCU callbacks that have started waiting
-        for a grace period since boot.  "na" should be roughly equal to
-        "nl" plus "wa".
-o       "wl" is the number of RCU callbacks currently waiting for their
-        grace period to end.
-o       "da" is the total number of RCU callbacks whose grace periods
-        have completed since boot.  "wa" should be roughly equal to
-        "wl" plus "da".
-o       "dr" is the total number of RCU callbacks that have been removed
-        from the list of callbacks ready to invoke.  "dr" should be roughly
-        equal to "da".
-o       "di" is the total number of RCU callbacks that have been invoked
-        since boot.  "di" should be roughly equal to "da", though some
-        early versions of preemptable RCU had a bug so that only the
-        last CPU's count of invocations was displayed, rather than the
-        sum of all CPU's counts.
-o       "1" is the number of calls to rcu_try_flip().  This should be
-        roughly equal to the sum of "e1", "i1", "a1", "z1", and "m1"
-        described below.  In other words, the number of times that
-        the state machine is visited should be equal to the sum of the
-        number of times that each state is visited plus the number of
-        times that the state-machine lock acquisition failed.
-o       "e1" is the number of times that rcu_try_flip() was unable to
-        acquire the fliplock.
-o       "i1" is the number of calls to rcu_try_flip_idle().
-o       "ie1" is the number of times rcu_try_flip_idle() exited early
-        due to the calling CPU having no work for RCU.
-o       "g1" is the number of times that rcu_try_flip_idle() decided
-        to start a new grace period.  "i1" should be roughly equal to
-        "ie1" plus "g1".
-o       "a1" is the number of calls to rcu_try_flip_waitack().
-o       "ae1" is the number of times that rcu_try_flip_waitack() found
-        that at least one CPU had not yet acknowledge the new grace period
-        (AKA "counter flip").
-o       "a2" is the number of time rcu_try_flip_waitack() found that
-        all CPUs had acknowledged.  "a1" should be roughly equal to
-        "ae1" plus "a2".  (This particular output was collected on
-        a 128-CPU machine, hence the smaller-than-usual fraction of
-        calls to rcu_try_flip_waitack() finding all CPUs having already
-        acknowledged.)
-o       "z1" is the number of calls to rcu_try_flip_waitzero().
-o       "ze1" is the number of times that rcu_try_flip_waitzero() found
-        that not all of the old RCU read-side critical sections had
-        completed.
-o       "z2" is the number of times that rcu_try_flip_waitzero() finds
-        the sum of the counters equal to zero, in other words, that
-        all of the old RCU read-side critical sections had completed.
-        The value of "z1" should be roughly equal to "ze1" plus
-        "z2".
-o       "m1" is the number of calls to rcu_try_flip_waitmb().
-o       "me1" is the number of times that rcu_try_flip_waitmb() finds
-        that at least one CPU has not yet executed a memory barrier.
-o       "m2" is the number of times that rcu_try_flip_waitmb() finds that
-        all CPUs have executed a memory barrier.

+OMAP2/3 Display Subsystem
+-------------------------
+This is an almost total rewrite of the OMAP FB driver in drivers/video/omap
+(let's call it DSS1). The main differences between DSS1 and DSS2 are DSI,
+TV-out and multiple display support, but there are lots of small improvements
+also.
+The DSS2 driver (omapdss module) is in arch/arm/plat-omap/dss/, and the FB,
+panel and controller drivers are in drivers/video/omap2/. DSS1 and DSS2 live
+currently side by side, you can choose which one to use.
+Features
+--------
+Working and tested features include:
+- MIPI DPI (parallel) output
+- MIPI DSI output in command mode
+- MIPI DBI (RFBI) output
+- SDI output
+- TV output
+- All pieces can be compiled as a module or inside kernel
+- Use DISPC to update any of the outputs
+- Use CPU to update RFBI or DSI output
+- OMAP DISPC planes
+- RGB16, RGB24 packed, RGB24 unpacked
+- YUV2, UYVY
+- Scaling
+- Adjusting DSS FCK to find a good pixel clock
+- Use DSI DPLL to create DSS FCK
+Tested boards include:
+- OMAP3 SDP board
+- Beagle board
+- N810
+omapdss driver
+--------------
+The DSS driver does not itself have any support for Linux framebuffer, V4L or
+such like the current ones, but it has an internal kernel API that upper level
+drivers can use.
+The DSS driver models OMAP's overlays, overlay managers and displays in a
+flexible way to enable non-common multi-display configuration. In addition to
+modelling the hardware overlays, omapdss supports virtual overlays and overlay
+managers. These can be used when updating a display with CPU or system DMA.
+Panel and controller drivers
+----------------------------
+The drivers implement panel or controller specific functionality and are not
+usually visible to users except through omapfb driver.  They register
+themselves to the DSS driver.
+omapfb driver
+-------------
+The omapfb driver implements arbitrary number of standard linux framebuffers.
+These framebuffers can be routed flexibly to any overlays, thus allowing very
+dynamic display architecture.
+The driver exports some omapfb specific ioctls, which are compatible with the
+ioctls in the old driver.
+The rest of the non standard features are exported via sysfs. Whether the final
+implementation will use sysfs, or ioctls, is still open.
+V4L2 drivers
+------------
+V4L2 is being implemented in TI.
+From omapdss point of view the V4L2 drivers should be similar to framebuffer
+driver.
+Architecture
+--------------------
+Some clarification what the different components do:
+    - Framebuffer is a memory area inside OMAP's SRAM/SDRAM that contains the
+      pixel data for the image. Framebuffer has width and height and color
+      depth.
+    - Overlay defines where the pixels are read from and where they go on the
+      screen. The overlay may be smaller than framebuffer, thus displaying only
+      part of the framebuffer. The position of the overlay may be changed if
+      the overlay is smaller than the display.
+    - Overlay manager combines the overlays in to one image and feeds them to
+      display.
+    - Display is the actual physical display device.
+A framebuffer can be connected to multiple overlays to show the same pixel data
+on all of the overlays. Note that in this case the overlay input sizes must be
+the same, but, in case of video overlays, the output size can be different. Any
+framebuffer can be connected to any overlay.
+An overlay can be connected to one overlay manager. Also DISPC overlays can be
+connected only to DISPC overlay managers, and virtual overlays can be only
+connected to virtual overlays.
+An overlay manager can be connected to one display. There are certain
+restrictions which kinds of displays an overlay manager can be connected:
+    - DISPC TV overlay manager can be only connected to TV display.
+    - Virtual overlay managers can only be connected to DBI or DSI displays.
+    - DISPC LCD overlay manager can be connected to all displays, except TV
+      display.
+Sysfs
+-----
+The sysfs interface is mainly used for testing. I don't think sysfs
+interface is the best for this in the final version, but I don't quite know
+what would be the best interfaces for these things.
+The sysfs interface is divided to two parts: DSS and FB.

+Examples
+--------
+The following definitions have been made for the examples below:
+ovl0=/sys/devices/platform/omapdss/overlay0
+ovl1=/sys/devices/platform/omapdss/overlay1
+ovl2=/sys/devices/platform/omapdss/overlay2
+mgr0=/sys/devices/platform/omapdss/manager0
+mgr1=/sys/devices/platform/omapdss/manager1
+lcd=/sys/devices/platform/omapdss/display0
+dvi=/sys/devices/platform/omapdss/display1
+tv=/sys/devices/platform/omapdss/display2
+fb0=/sys/class/graphics/fb0
+fb1=/sys/class/graphics/fb1
+fb2=/sys/class/graphics/fb2
+Default setup on OMAP3 SDP
+--------------------------
+Here's the default setup on OMAP3 SDP board. All planes go to LCD. DVI
+and TV-out are not in use. The columns from left to right are:
+framebuffers, overlays, overlay managers, displays. Framebuffers are
+handled by omapfb, and the rest by the DSS.
+FB0 --- GFX  -\            DVI
+FB1 --- VID1 --+- LCD ---- LCD
+FB2 --- VID2 -/   TV ----- TV
+Example: Switch from LCD to DVI
+----------------------
+w=`cat $dvi/timings | cut -d "," -f 2 | cut -d "/" -f 1`
+h=`cat $dvi/timings | cut -d "," -f 3 | cut -d "/" -f 1`
+echo "0" > $lcd/enabled
+echo "" > $mgr0/display
+fbset -fb /dev/fb0 -xres $w -yres $h -vxres $w -vyres $h
+# at this point you have to switch the dvi/lcd dip-switch from the omap board
+echo "dvi" > $mgr0/display
+echo "1" > $dvi/enabled
+After this the configuration looks like:
+FB0 --- GFX  -\         -- DVI
+FB1 --- VID1 --+- LCD -/   LCD
+FB2 --- VID2 -/   TV ----- TV
+Example: Clone GFX overlay to LCD and TV
+-------------------------------
+w=`cat $tv/timings | cut -d "," -f 2 | cut -d "/" -f 1`
+h=`cat $tv/timings | cut -d "," -f 3 | cut -d "/" -f 1`
+echo "0" > $ovl0/enabled
+echo "0" > $ovl1/enabled
+echo "" > $fb1/overlays
+echo "0,1" > $fb0/overlays
+echo "$w,$h" > $ovl1/output_size
+echo "tv" > $ovl1/manager
+echo "1" > $ovl0/enabled
+echo "1" > $ovl1/enabled
+echo "1" > $tv/enabled
+After this the configuration looks like (only relevant parts shown):
+FB0 +-- GFX  ---- LCD ---- LCD
+     \- VID1 ---- TV  ---- TV
+Misc notes
+----------
+OMAP FB allocates the framebuffer memory using the OMAP VRAM allocator.
+Using DSI DPLL to generate pixel clock it is possible produce the pixel clock
+of 86.5MHz (max possible), and with that you get 1280x1024@57 output from DVI.
+Rotation and mirroring currently only supports RGB565 and RGB8888 modes. VRFB
+does not support mirroring.
+VRFB rotation requires much more memory than non-rotated framebuffer, so you
+probably need to increase your vram setting before using VRFB rotation. Also,
+many applications may not work with VRFB if they do not pay attention to all
+framebuffer parameters.
+Kernel boot arguments
+---------------------
+vram=<size>
+        - Amount of total VRAM to preallocate. For example, "10M". omapfb
+          allocates memory for framebuffers from VRAM.
+omapfb.mode=<display>:<mode>[,...]
+        - Default video mode for specified displays. For example,
+          "dvi:800x400MR-24@60".  See drivers/video/modedb.c.
+          There are also two special modes: "pal" and "ntsc" that
+          can be used to tv out.
+omapfb.vram=<fbnum>:<size>[@<physaddr>][,...]
+        - VRAM allocated for a framebuffer. Normally omapfb allocates vram
+          depending on the display size. With this you can manually allocate
+          more or define the physical address of each framebuffer. For example,
+          "1:4M" to allocate 4M for fb1.
+omapfb.debug=<y|n>
+        - Enable debug printing. You have to have OMAPFB debug support enabled
+          in kernel config.
+omapfb.test=<y|n>
+        - Draw test pattern to framebuffer whenever framebuffer settings change.
+          You need to have OMAPFB debug support enabled in kernel config.
+omapfb.vrfb=<y|n>
+        - Use VRFB rotation for all framebuffers.
+omapfb.rotate=<angle>
+        - Default rotation applied to all framebuffers.
+          0 - 0 degree rotation
+          1 - 90 degree rotation
+          2 - 180 degree rotation
+          3 - 270 degree rotation
+omapfb.mirror=<y|n>
+        - Default mirror for all framebuffers. Only works with DMA rotation.
+omapdss.def_disp=<display>
+        - Name of default display, to which all overlays will be connected.
+          Common examples are "lcd" or "tv".
+omapdss.debug=<y|n>
+        - Enable debug printing. You have to have DSS debug support enabled in
+          kernel config.
+TODO
+----
+DSS locking
+Error checking
+- Lots of checks are missing or implemented just as BUG()
+System DMA update for DSI
+- Can be used for RGB16 and RGB24P modes. Probably not for RGB24U (how
+  to skip the empty byte?)
+OMAP1 support
+- Not sure if needed

+Description
+  DRBD is a shared-nothing, synchronously replicated block device. It
+  is designed to serve as a building block for high availability
+  clusters and in this context, is a "drop-in" replacement for shared
+  storage. Simplistically, you could see it as a network RAID 1.
+  Please visit http://www.drbd.org to find out more.

+                                Block IO Controller
+                                ===================
+Overview
+========
+cgroup subsys "blkio" implements the block io controller. There seems to be
+a need of various kinds of IO control policies (like proportional BW, max BW)
+both at leaf nodes as well as at intermediate nodes in a storage hierarchy.
+Plan is to use the same cgroup based management interface for blkio controller
+and based on user options switch IO policies in the background.
+In the first phase, this patchset implements proportional weight time based
+division of disk policy. It is implemented in CFQ. Hence this policy takes
+effect only on leaf nodes when CFQ is being used.
+HOWTO
+=====
+You can do a very simple testing of running two dd threads in two different
+cgroups. Here is what you can do.
+- Enable group scheduling in CFQ
+        CONFIG_CFQ_GROUP_IOSCHED=y
+- Compile and boot into kernel and mount IO controller (blkio).
+        mount -t cgroup -o blkio none /cgroup
+- Create two cgroups
+        mkdir -p /cgroup/test1/ /cgroup/test2
+- Set weights of group test1 and test2
+        echo 1000 > /cgroup/test1/blkio.weight
+        echo 500 > /cgroup/test2/blkio.weight
+- Create two same size files (say 512MB each) on same disk (file1, file2) and
+  launch two dd threads in different cgroup to read those files.
+        sync
+        echo 3 > /proc/sys/vm/drop_caches
+        dd if=/mnt/sdb/zerofile1 of=/dev/null &
+        echo $! > /cgroup/test1/tasks
+        cat /cgroup/test1/tasks
+        dd if=/mnt/sdb/zerofile2 of=/dev/null &
+        echo $! > /cgroup/test2/tasks
+        cat /cgroup/test2/tasks
+- At macro level, first dd should finish first. To get more precise data, keep
+  on looking at (with the help of script), at blkio.disk_time and
+  blkio.disk_sectors files of both test1 and test2 groups. This will tell how
+  much disk time (in milli seconds), each group got and how many secotors each
+  group dispatched to the disk. We provide fairness in terms of disk time, so
+  ideally io.disk_time of cgroups should be in proportion to the weight.
+Various user visible config options
+===================================
+CONFIG_CFQ_GROUP_IOSCHED
+        - Enables group scheduling in CFQ. Currently only 1 level of group
+          creation is allowed.
+CONFIG_DEBUG_CFQ_IOSCHED
+        - Enables some debugging messages in blktrace. Also creates extra
+          cgroup file blkio.dequeue.
+Config options selected automatically
+=====================================
+These config options are not user visible and are selected/deselected
+automatically based on IO scheduler configuration.
+CONFIG_BLK_CGROUP
+        - Block IO controller. Selected by CONFIG_CFQ_GROUP_IOSCHED.
+CONFIG_DEBUG_BLK_CGROUP
+        - Debug help. Selected by CONFIG_DEBUG_CFQ_IOSCHED.
+Details of cgroup files
+=======================
+- blkio.weight
+        - Specifies per cgroup weight.
+          Currently allowed range of weights is from 100 to 1000.
+- blkio.time
+        - disk time allocated to cgroup per device in milliseconds. First
+          two fields specify the major and minor number of the device and
+          third field specifies the disk time allocated to group in
+          milliseconds.
+- blkio.sectors
+        - number of sectors transferred to/from disk by the group. First
+          two fields specify the major and minor number of the device and
+          third field specifies the number of sectors transferred by the
+          group to/from the device.
+- blkio.dequeue
+        - Debugging aid only enabled if CONFIG_DEBUG_CFQ_IOSCHED=y. This
+          gives the statistics about how many a times a group was dequeued
+          from service tree of the device. First two fields specify the major
+          and minor number of the device and third field specifies the number
+          of times a group was dequeued from a particular device.
+CFQ sysfs tunable
+=================
+/sys/block/<disk>/queue/iosched/group_isolation
+If group_isolation=1, it provides stronger isolation between groups at the
+expense of throughput. By default group_isolation is 0. In general that
+means that if group_isolation=0, expect fairness for sequential workload
+only. Set group_isolation=1 to see fairness for random IO workload also.
+Generally CFQ will put random seeky workload in sync-noidle category. CFQ
+will disable idling on these queues and it does a collective idling on group
+of such queues. Generally these are slow moving queues and if there is a
+sync-noidle service tree in each group, that group gets exclusive access to
+disk for certain period. That means it will bring the throughput down if
+group does not have enough IO to drive deeper queue depths and utilize disk
+capacity to the fullest in the slice allocated to it. But the flip side is
+that even a random reader should get better latencies and overall throughput
+if there are lots of sequential readers/sync-idle workload running in the
+system.
+If group_isolation=0, then CFQ automatically moves all the random seeky queues
+in the root group. That means there will be no service differentiation for
+that kind of workload. This leads to better throughput as we do collective
+idling on root sync-noidle tree.
+By default one should run with group_isolation=0. If that is not sufficient
+and one wants stronger isolation between groups, then set group_isolation=1
+but this will come at cost of reduced throughput.
+What works
+==========
+- Currently only sync IO queues are support. All the buffered writes are
+  still system wide and not per group. Hence we will not see service
+  differentiation between buffered writes between groups.

+Fan Speed Control
+-----------------
+The driver exposes two trip points per PWM channel.
+point1: Set the PWM speed at the lower temperature bound
+point2: Set the PWM speed at the higher temperature bound
+The ADT747x will scale the PWM linearly between the lower and higher PWM
+speed when the temperature is between the two temperature boundaries.
+Temperature boundaries are associated to temperature channels rather than
+PWM outputs, and a given PWM output can be controlled by several temperature
+channels. As a result, the ADT747x may compute more than one PWM value
+for a channel at a given time, in which case the maximum value (fastest
+fan speed) is applied. PWM values range from 0 (off) to 255 (full speed).
+Fan speed may be set to maximum when the temperature sensor associated with
+the PWM control exceeds temp#_max.
+Notes
+-----
+The nVidia binary driver presents an ADT7473 chip via an on-card i2c bus.
+Unfortunately, they fail to set the i2c adapter class, so this driver may
+fail to find the chip until the nvidia driver is patched.

+Description
+-----------
+The Freescale MC13783 is a Power Management and Audio Circuit. Among
+other things it contains a 10-bit A/D converter. The converter has 16
+channels which can be used in different modes.
+The A/D converter has a resolution of 2.25mV. Channels 0-4 have
+a dedicated meaning with chip internal scaling applied. Channels 5-7
+can be used as general purpose inputs or alternatively in a dedicated
+mode. Channels 12-15 are occupied by the touchscreen if it's active.
+Currently the driver only supports channels 2 and 5-15 with no alternative
+modes for channels 5-7.
+See this table for the meaning of the different channels and their chip

-Description
-----------
-The 3dfx Voodoo3 chip contains two I2C interfaces (aka a I2C 'master' or
-'host'). 
-The first interface is used for DDC (Data Display Channel) which is a
-serial channel through the VGA monitor connector to a DDC-compliant
-monitor. This interface is defined by the Video Electronics Standards
-Association (VESA). The standards are available for purchase at
-http://www.vesa.org .
-The second interface is a general-purpose I2C bus. The intent by 3dfx was
-to allow manufacturers to add extra chips to the video card such as a
-TV-out chip such as the BT869 or possibly even I2C based temperature
-sensors like the ADM1021 or LM75.
-Stability
---------
-Seems to be stable on the test machine, but needs more testing on other
-machines. Simultaneous accesses of the DDC and I2C busses may cause errors.
-Supported Devices
-----------------
-Specifically, this driver was written and tested on the '3dfx Voodoo3 AGP
-3000' which has a tv-out feature (s-video or composite).  According to the
-docs and discussions, this code should work for any Voodoo3 based cards as
-well as Voodoo Banshee based cards.  The DDC interface has been tested on a
-Voodoo Banshee card.

-Issues
------
-Probably many, but it seems to work OK on my system. :')
-External Device Connection

-The digital video input jumpers give availability to the I2C bus. 
-Specifically, pins 13 and 25 (bottom row middle, and bottom right-end) are     
-the I2C clock and I2C data lines, respectively. +5V and GND are probably
-also easily available making the addition of extra I2C/SMBus devices easy

+I2C device driver binding control from user-space
+=================================================
+Up to kernel 2.6.32, many i2c drivers used helper macros provided by
+<linux/i2c.h> which created standard module parameters to let the user
+control how the driver would probe i2c buses and attach to devices. These
+parameters were known as "probe" (to let the driver probe for an extra
+address), "force" (to forcibly attach the driver to a given device) and
+"ignore" (to prevent a driver from probing a given address).
+With the conversion of the i2c subsystem to the standard device driver
+binding model, it became clear that these per-module parameters were no
+longer needed, and that a centralized implementation was possible. The new,
+sysfs-based interface is described in the documentation file
+"instantiating-devices", section "Method 4: Instantiate from user-space".
+Below is a mapping from the old module parameters to the new interface.
+Attaching a driver to an I2C device
+-----------------------------------
+Old method (module parameters):
+# modprobe <driver> probe=1,0x2d
+# modprobe <driver> force=1,0x2d
+# modprobe <driver> force_<device>=1,0x2d
+New method (sysfs interface):
+# echo <device> 0x2d > /sys/bus/i2c/devices/i2c-1/new_device
+Preventing a driver from attaching to an I2C device
+---------------------------------------------------
+Old method (module parameters):
+# modprobe <driver> ignore=1,0x2f
+New method (sysfs interface):
+# echo dummy 0x2f > /sys/bus/i2c/devices/i2c-1/new_device
+# modprobe <driver>
+Of course, it is important to instantiate the "dummy" device before loading
+the driver. The dummy device will be handled by i2c-core itself, preventing
+other drivers from binding to it later on. If there is a real device at the
+problematic address, and you want another driver to bind to it, then simply
+pass the name of the device in question instead of "dummy".

+The ad525x_dpot driver exports a simple sysfs interface.  This allows you to
+work with the immediate resistance settings as well as update the saved startup
+settings.  Access to the factory programmed tolerance is also provided, but
+interpretation of this settings is required by the end application according to
+the specific part in use.
+---------
+  Files
+---------
+Each dpot device will have a set of eeprom, rdac, and tolerance files.  How
+many depends on the actual part you have, as will the range of allowed values.
+The eeprom files are used to program the startup value of the device.
+The rdac files are used to program the immediate value of the device.
+The tolerance files are the read-only factory programmed tolerance settings
+and may vary greatly on a part-by-part basis.  For exact interpretation of
+this field, please consult the datasheet for your part.  This is presented
+as a hex file for easier parsing.
+-----------
+  Example
+-----------
+Locate the device in your sysfs tree.  This is probably easiest by going into
+the common i2c directory and locating the device by the i2c slave address.
+        # ls /sys/bus/i2c/devices/
+        0-0022  0-0027  0-002f
+So assuming the device in question is on the first i2c bus and has the slave
+address of 0x2f, we descend (unrelated sysfs entries have been trimmed).
+        # ls /sys/bus/i2c/devices/0-002f/
+        eeprom0 rdac0 tolerance0
+You can use simple reads/writes to access these files:

+        # cat eeprom0
+        0

+     mapping.
+     In the no-MMU case, however, anonymous mappings are backed by physical

+     significant delays during a userspace malloc() as the C library does an
+     anonymous mapping and the kernel then does a memset for the entire map.

-HAYES ESP DRIVER VERSION 2.1
-A big thanks to the people at Hayes, especially Alan Adamson.  Their support
-has enabled me to provide enhancements to the driver.
-Please report your experiences with this driver to me (arobinso@nyx.net).  I
-am looking for both positive and negative feedback.
-*** IMPORTANT CHANGES FOR 2.1 ***
-Support for PIO mode.  Five situations will cause PIO mode to be used:
-1) A multiport card is detected.  PIO mode will always be used.  (8 port cards
-do not support DMA).
-2) The DMA channel is set to an invalid value (anything other than 1 or 3).
-3) The DMA buffer/channel could not be allocated.  The port will revert to PIO
-mode until it is reopened.
-4) Less than a specified number of bytes need to be transferred to/from the
-FIFOs.  PIO mode will be used for that transfer only.
-5) A port needs to do a DMA transfer and another port is already using the
-DMA channel.  PIO mode will be used for that transfer only.
-Since the Hayes ESP seems to conflict with other cards (notably sound cards)
-when using DMA, DMA is turned off by default.  To use DMA, it must be turned
-on explicitly, either with the "dma=" option described below or with
-setserial.  A multiport card can be forced into DMA mode by using setserial;
-however, most multiport cards don't support DMA.
-The latest version of setserial allows the enhanced configuration of the ESP
-card to be viewed and modified.
-***
-This package contains the files needed to compile a module to support the Hayes
-ESP card.  The drivers are basically a modified version of the serial drivers.
-Features:
- Uses the enhanced mode of the ESP card, allowing a wider range of
-  interrupts and features than compatibility mode
- Uses DMA and 16 bit PIO mode to transfer data to and from the ESP's FIFOs,
-  reducing CPU load
- Supports primary and secondary ports
-If the driver is compiled as a module, the IRQs to use can be specified by
-using the irq= option.  The format is:
-irq=[0x100],[0x140],[0x180],[0x200],[0x240],[0x280],[0x300],[0x380]
-The address in brackets is the base address of the card.  The IRQ of
-nonexistent cards can be set to 0.  If an IRQ of a card that does exist is set
-to 0, the driver will attempt to guess at the correct IRQ.  For example, to set
-the IRQ of the card at address 0x300 to 12, the insmod command would be:
-insmod esp irq=0,0,0,0,0,0,12,0
-The custom divisor can be set by using the divisor= option.  The format is the
-same as for the irq= option.  Each divisor value is a series of hex digits,
-with each digit representing the divisor to use for a corresponding port.  The
-divisor value is constructed RIGHT TO LEFT.  Specifying a nonzero divisor value
-will automatically set the spd_cust flag.  To calculate the divisor to use for
-a certain baud rate, divide the port's base baud (generally 921600) by the
-desired rate.  For example, to set the divisor of the primary port at 0x300 to
-4 and the divisor of the secondary port at 0x308 to 8, the insmod command would
-be:
-insmod esp divisor=0,0,0,0,0,0,0x84,0
-The dma= option can be used to set the DMA channel.  The channel can be either
-1 or 3.  Specifying any other value will force the driver to use PIO mode.
-For example, to set the DMA channel to 3, the insmod command would be:
-insmod esp dma=3
-The rx_trigger= and tx_trigger= options can be used to set the FIFO trigger
-levels.  They specify when the ESP card should send an interrupt.  Larger
-values will decrease the number of interrupts; however, a value too high may
-result in data loss.  Valid values are 1 through 1023, with 768 being the
-default.  For example, to set the receive trigger level to 512 bytes and the
-transmit trigger level to 700 bytes, the insmod command would be:
-insmod esp rx_trigger=512 tx_trigger=700
-The flow_off= and flow_on= options can be used to set the hardware flow off/
-flow on levels.  The flow on level must be lower than the flow off level, and
-the flow off level should be higher than rx_trigger.  Valid values are 1
-through 1023, with 1016 being the default flow off level and 944 being the
-default flow on level.  For example, to set the flow off level to 1000 bytes
-and the flow on level to 935 bytes, the insmod command would be:
-insmod esp flow_off=1000 flow_on=935
-The rx_timeout= option can be used to set the receive timeout value.  This
-value indicates how long after receiving the last character that the ESP card
-should wait before signalling an interrupt.  Valid values are 0 though 255,
-with 128 being the default.  A value too high will increase latency, and a
-value too low will cause unnecessary interrupts.  For example, to set the
-receive timeout to 255, the insmod command would be:
-insmod esp rx_timeout=255
-The pio_threshold= option sets the threshold (in number of characters) for
-using PIO mode instead of DMA mode.  For example, if this value is 32,
-transfers of 32 bytes or less will always use PIO mode.
-insmod esp pio_threshold=32
-Multiple options can be listed on the insmod command line by separating each
-option with a space.  For example:
-insmod esp dma=3 trigger=512
-The esp module can be automatically loaded when needed.  To cause this to
-happen, add the following lines to /etc/modprobe.conf (replacing the last line
-with options for your configuration):
-alias char-major-57 esp
-alias char-major-58 esp
-options esp irq=0,0,0,0,0,0,3,0 divisor=0,0,0,0,0,0,0x4,0
-You may also need to run 'depmod -a'.
-Devices must be created manually.  To create the devices, note the output from
-the module after it is inserted.  The output will appear in the location where
-kernel messages usually appear (usually /var/adm/messages).  Create two devices
-for each 'tty' mentioned, one with major of 57 and the other with major of 58.
-The minor number should be the same as the tty number reported.  The commands
-would be (replace ? with the tty number):
-mknod /dev/ttyP? c 57 ?
-mknod /dev/cup? c 58 ?
-For example, if the following line appears:
-Oct 24 18:17:23 techno kernel: ttyP8 at 0x0140 (irq = 3) is an ESP primary port
-...two devices should be created:
-mknod /dev/ttyP8 c 57 8
-mknod /dev/cup8 c 58 8
-You may need to set the permissions on the devices:
-chmod 666 /dev/ttyP*
-chmod 666 /dev/cup*
-The ESP module and the serial module should not conflict (they can be used at
-the same time).  After the ESP module has been loaded the ports on the ESP card
-will no longer be accessible by the serial driver.
-If I/O errors are experienced when accessing the port, check for IRQ and DMA
-conflicts ('cat /proc/interrupts' and 'cat /proc/dma' for a list of IRQs and
-DMAs currently in use).
-Enjoy!

+================
+HELPER FUNCTIONS
+================
+The slow-work facility provides a function by which it can be determined
+whether or not an item is queued for later execution:
+        bool queued = slow_work_is_queued(struct slow_work *work);
+If it returns false, then the item is not on the queue (it may be executing
+with a requeue pending).  This can be used to work out whether an item on which
+another depends is on the queue, thus allowing a dependent item to be queued
+after it.
+If the above shows an item on which another depends not to be queued, then the
+owner of the dependent item might need to wait.  However, to avoid locking up
+the threads unnecessarily be sleeping in them, it can make sense under some
+circumstances to return the work item to the queue, thus deferring it until
+some other items have had a chance to make use of the yielded thread.
+To yield a thread and defer an item, the work function should simply enqueue
+the work item again and return.  However, this doesn't work if there's nothing
+actually on the queue, as the thread just vacated will jump straight back into
+the item's work function, thus busy waiting on a CPU.
+Instead, the item should use the thread to wait for the dependency to go away,
+but rather than using schedule() or schedule_timeout() to sleep, it should use
+the following function:
+        bool requeue = slow_work_sleep_till_thread_needed(
+                        struct slow_work *work,
+                        signed long *_timeout);
+This will add a second wait and then sleep, such that it will be woken up if
+either something appears on the queue that could usefully make use of the
+thread - and behind which this item can be queued, or if the event the caller
+set up to wait for happens.  True will be returned if something else appeared
+on the queue and this work function should perhaps return, of false if
+something else woke it up.  The timeout is as for schedule_timeout().
+For example:
+        wq = bit_waitqueue(&my_flags, MY_BIT);
+        init_wait(&wait);
+        requeue = false;
+        do {
+                prepare_to_wait(wq, &wait, TASK_UNINTERRUPTIBLE);
+                if (!test_bit(MY_BIT, &my_flags))

-Except for a few extremely rare exceptions user space applications do not use

-Recently the kernel has started supporting setting the binary sysctl value to
-CTL_UNNUMBERED so we no longer need to assign a binary sysctl path to allow
-sysctls to show up in /proc/sys.
-Assigning binary sysctl numbers is an endless source of conflicts in sysctl.h,

+                        Kprobe-based Event Tracing
+                        ==========================
+                 Documentation is written by Masami Hiramatsu
+Overview
+--------
+These events are similar to tracepoint based events. Instead of Tracepoint,
+this is based on kprobes (kprobe and kretprobe). So it can probe wherever
+kprobes can probe (this means, all functions body except for __kprobes
+functions). Unlike the Tracepoint based event, this can be added and removed
+dynamically, on the fly.
+To enable this feature, build your kernel with CONFIG_KPROBE_TRACING=y.
+Similar to the events tracer, this doesn't need to be activated via
+current_tracer. Instead of that, add probe points via
+/sys/kernel/debug/tracing/kprobe_events, and enable it via
+/sys/kernel/debug/tracing/events/kprobes/<EVENT>/enabled.
+Synopsis of kprobe_events
+-------------------------
+  p[:[GRP/]EVENT] SYMBOL[+offs]|MEMADDR [FETCHARGS]     : Set a probe
+  r[:[GRP/]EVENT] SYMBOL[+0] [FETCHARGS]                : Set a return probe
+ GRP            : Group name. If omitted, use "kprobes" for it.
+ EVENT          : Event name. If omitted, the event name is generated
+                  based on SYMBOL+offs or MEMADDR.
+ SYMBOL[+offs]  : Symbol+offset where the probe is inserted.
+ MEMADDR        : Address where the probe is inserted.
+ FETCHARGS      : Arguments. Each probe can have up to 128 args.
+  %REG          : Fetch register REG
+  @ADDR         : Fetch memory at ADDR (ADDR should be in kernel)
+  @SYM[+|-offs] : Fetch memory at SYM +|- offs (SYM should be a data symbol)
+  $stackN       : Fetch Nth entry of stack (N >= 0)
+  $stack        : Fetch stack address.
+  $argN         : Fetch function argument. (N >= 0)(*)
+  $retval       : Fetch return value.(**)
+  +|-offs(FETCHARG) : Fetch memory at FETCHARG +|- offs address.(***)
+  NAME=FETCHARG: Set NAME as the argument name of FETCHARG.
+  (*) aN may not correct on asmlinkaged functions and at the middle of
+      function body.
+  (**) only for return probe.
+  (***) this is useful for fetching a field of data structures.
+Per-Probe Event Filtering
+-------------------------
+ Per-probe event filtering feature allows you to set different filter on each
+probe and gives you what arguments will be shown in trace buffer. If an event
+name is specified right after 'p:' or 'r:' in kprobe_events, it adds an event
+under tracing/events/kprobes/<EVENT>, at the directory you can see 'id',
+'enabled', 'format' and 'filter'.
+enabled:
+  You can enable/disable the probe by writing 1 or 0 on it.
+format:
+  This shows the format of this probe event.
+filter:
+  You can write filtering rules of this event.
+id:
+  This shows the id of this probe event.
+Event Profiling
+---------------
+ You can check the total number of probe hits and probe miss-hits via
+/sys/kernel/debug/tracing/kprobe_profile.
+ The first column is event name, the second is the number of probe hits,
+the third is the number of probe miss-hits.
+Usage examples
+--------------
+To add a probe as a new event, write a new definition to kprobe_events
+as below.
+  echo p:myprobe do_sys_open dfd=$arg0 filename=$arg1 flags=$arg2 mode=$arg3 > /sys/kernel/debug/tracing/kprobe_events
+ This sets a kprobe on the top of do_sys_open() function with recording
+1st to 4th arguments as "myprobe" event. As this example shows, users can
+choose more familiar names for each arguments.
+  echo r:myretprobe do_sys_open $retval >> /sys/kernel/debug/tracing/kprobe_events
+ This sets a kretprobe on the return point of do_sys_open() function with
+recording return value as "myretprobe" event.
+ You can see the format of these events via
+/sys/kernel/debug/tracing/events/kprobes/<EVENT>/format.
+  cat /sys/kernel/debug/tracing/events/kprobes/myprobe/format
+name: myprobe
+ID: 75
+format:
+        field:unsigned short common_type;       offset:0;       size:2;
+        field:unsigned char common_flags;       offset:2;       size:1;
+        field:unsigned char common_preempt_count;       offset:3;       size:1;
+        field:int common_pid;   offset:4;       size:4;
+        field:int common_tgid;  offset:8;       size:4;
+        field: unsigned long ip;        offset:16;tsize:8;
+        field: int nargs;       offset:24;tsize:4;
+        field: unsigned long dfd;       offset:32;tsize:8;

+        field: unsigned long flags;     offset:48;tsize:8;
+        field: unsigned long mode;      offset:56;tsize:8;
+print fmt: "(%lx) dfd=%lx filename=%lx flags=%lx mode=%lx", REC->ip, REC->dfd, REC->filename, REC->flags, REC->mode
+ You can see that the event has 4 arguments as in the expressions you specified.
+  echo > /sys/kernel/debug/tracing/kprobe_events
+ This clears all probe points.
+ Right after definition, each event is disabled by default. For tracing these
+events, you need to enable it.
+  echo 1 > /sys/kernel/debug/tracing/events/kprobes/myprobe/enable
+  echo 1 > /sys/kernel/debug/tracing/events/kprobes/myretprobe/enable
+ And you can see the traced information via /sys/kernel/debug/tracing/trace.

+Interaction of Task Memory Policy with Huge Page Allocation/Freeing
+Whether huge pages are allocated and freed via the /proc interface or
+the /sysfs interface using the nr_hugepages_mempolicy attribute, the NUMA
+nodes from which huge pages are allocated or freed are controlled by the
+NUMA memory policy of the task that modifies the nr_hugepages_mempolicy
+sysctl or attribute.  When the nr_hugepages attribute is used, mempolicy
+is ignored.
+The recommended method to allocate or free huge pages to/from the kernel
+huge page pool, using the nr_hugepages example above, is:
+    numactl --interleave <node-list> echo 20 \
+                                >/proc/sys/vm/nr_hugepages_mempolicy
+or, more succinctly:
+    numactl -m <node-list> echo 20 >/proc/sys/vm/nr_hugepages_mempolicy
+This will allocate or free abs(20 - nr_hugepages) to or from the nodes
+specified in <node-list>, depending on whether number of persistent huge pages
+is initially less than or greater than 20, respectively.  No huge pages will be
+allocated nor freed on any node not included in the specified <node-list>.
+When adjusting the persistent hugepage count via nr_hugepages_mempolicy, any
+memory policy mode--bind, preferred, local or interleave--may be used.  The
+resulting effect on persistent huge page allocation is as follows:
+1) Regardless of mempolicy mode [see Documentation/vm/numa_memory_policy.txt],
+   persistent huge pages will be distributed across the node or nodes
+   specified in the mempolicy as if "interleave" had been specified.
+   However, if a node in the policy does not contain sufficient contiguous
+   memory for a huge page, the allocation will not "fallback" to the nearest
+   neighbor node with sufficient contiguous memory.  To do this would cause
+   undesirable imbalance in the distribution of the huge page pool, or
+   possibly, allocation of persistent huge pages on nodes not allowed by
+   the task's memory policy.
+2) One or more nodes may be specified with the bind or interleave policy.
+   If more than one node is specified with the preferred policy, only the
+   lowest numeric id will be used.  Local policy will select the node where
+   the task is running at the time the nodes_allowed mask is constructed.
+   For local policy to be deterministic, the task must be bound to a cpu or
+   cpus in a single node.  Otherwise, the task could be migrated to some
+   other node at any time after launch and the resulting node will be
+   indeterminate.  Thus, local policy is not very useful for this purpose.
+   Any of the other mempolicy modes may be used to specify a single node.
+3) The nodes allowed mask will be derived from any non-default task mempolicy,
+   whether this policy was set explicitly by the task itself or one of its
+   ancestors, such as numactl.  This means that if the task is invoked from a
+   shell with non-default policy, that policy will be used.  One can specify a
+   node list of "all" with numactl --interleave or --membind [-m] to achieve
+   interleaving over all nodes in the system or cpuset.
+4) Any task mempolicy specifed--e.g., using numactl--will be constrained by
+   the resource limits of any cpuset in which the task runs.  Thus, there will
+   be no way for a task with non-default policy running in a cpuset with a
+   subset of the system nodes to allocate huge pages outside the cpuset
+   without first moving to a cpuset that contains all of the desired nodes.
+5) Boot-time huge page allocation attempts to distribute the requested number
+   of huge pages over all on-lines nodes with memory.
+Per Node Hugepages Attributes
+A subset of the contents of the root huge page control directory in sysfs,
+described above, will be replicated under each the system device of each
+NUMA node with memory in:
+        /sys/devices/system/node/node[0-9]*/hugepages/
+Under this directory, the subdirectory for each supported huge page size
