It is impossible to know if the status returned through sysfs is valid.
-Docking / undocking -- /proc/acpi/ibm/dock
-------------------------------------------
-
-Docking and undocking (e.g. with the X4 UltraBase) requires some
-actions to be taken by the operating system to safely make or break
-the electrical connections with the dock.
-
-The docking feature of this driver generates the following ACPI events:
-
- ibm/dock GDCK 00000003 00000001 -- eject request
- ibm/dock GDCK 00000003 00000002 -- undocked
- ibm/dock GDCK 00000000 00000003 -- docked
-
-NOTE: These events will only be generated if the laptop was docked
-when originally booted. This is due to the current lack of support for
-hot plugging of devices in the Linux ACPI framework. If the laptop was
-booted while not in the dock, the following message is shown in the
-logs:
-
- Mar 17 01:42:34 aero kernel: thinkpad_acpi: dock device not present
-
-In this case, no dock-related events are generated but the dock and
-undock commands described below still work. They can be executed
-manually or triggered by Fn key combinations (see the example acpid
-configuration files included in the driver tarball package available
-on the web site).
-
-When the eject request button on the dock is pressed, the first event
-above is generated. The handler for this event should issue the
-following command:
-
- echo undock > /proc/acpi/ibm/dock
-
-After the LED on the dock goes off, it is safe to eject the laptop.
-Note: if you pressed this key by mistake, go ahead and eject the
-laptop, then dock it back in. Otherwise, the dock may not function as
-expected.
-
-When the laptop is docked, the third event above is generated. The
-handler for this event should issue the following command to fully
-enable the dock:
-
- echo dock > /proc/acpi/ibm/dock
-
-The contents of the /proc/acpi/ibm/dock file shows the current status
-of the dock, as provided by the ACPI framework.
-
-The docking support in this driver does not take care of enabling or
-disabling any other devices you may have attached to the dock. For
-example, a CD drive plugged into the UltraBase needs to be disabled or
-enabled separately. See the provided example acpid configuration files
-for how this can be accomplished.
-
-There is no support yet for PCI devices that may be attached to a
-docking station, e.g. in the ThinkPad Dock II. The driver currently
-does not recognize, enable or disable such devices. This means that
-the only docking stations currently supported are the X-series
-UltraBase docks and "dumb" port replicators like the Mini Dock (the
-latter don't need any ACPI support, actually).
-
-
-UltraBay eject -- /proc/acpi/ibm/bay
-------------------------------------
-
-Inserting or ejecting an UltraBay device requires some actions to be
-taken by the operating system to safely make or break the electrical
-connections with the device.
-
-This feature generates the following ACPI events:
-
- ibm/bay MSTR 00000003 00000000 -- eject request
- ibm/bay MSTR 00000001 00000000 -- eject lever inserted
-
-NOTE: These events will only be generated if the UltraBay was present
-when the laptop was originally booted (on the X series, the UltraBay
-is in the dock, so it may not be present if the laptop was undocked).
-This is due to the current lack of support for hot plugging of devices
-in the Linux ACPI framework. If the laptop was booted without the
-UltraBay, the following message is shown in the logs:
-
- Mar 17 01:42:34 aero kernel: thinkpad_acpi: bay device not present
-
-In this case, no bay-related events are generated but the eject
-command described below still works. It can be executed manually or
-triggered by a hot key combination.
-
-Sliding the eject lever generates the first event shown above. The
-handler for this event should take whatever actions are necessary to
-shut down the device in the UltraBay (e.g. call idectl), then issue
-the following command:
-
- echo eject > /proc/acpi/ibm/bay
-
-After the LED on the UltraBay goes off, it is safe to pull out the
-device.
-
-When the eject lever is inserted, the second event above is
-generated. The handler for this event should take whatever actions are
-necessary to enable the UltraBay device (e.g. call idectl).
-
-The contents of the /proc/acpi/ibm/bay file shows the current status
-of the UltraBay, as provided by the ACPI framework.
-
-EXPERIMENTAL warm eject support on the 600e/x, A22p and A3x (To use
-this feature, you need to supply the experimental=1 parameter when
-loading the module):
-
-These models do not have a button near the UltraBay device to request
-a hot eject but rather require the laptop to be put to sleep
-(suspend-to-ram) before the bay device is ejected or inserted).
-The sequence of steps to eject the device is as follows:
-
- echo eject > /proc/acpi/ibm/bay
- put the ThinkPad to sleep
- remove the drive
- resume from sleep
- cat /proc/acpi/ibm/bay should show that the drive was removed
-
-On the A3x, both the UltraBay 2000 and UltraBay Plus devices are
-supported. Use "eject2" instead of "eject" for the second bay.
-
-Note: the UltraBay eject support on the 600e/x, A22p and A3x is
-EXPERIMENTAL and may not work as expected. USE WITH CAUTION!

+Early Patching
+~~~~~~~~~~~~~~
+When CONFIG_SND_HDA_PATCH_LOADER=y is set, you can pass a "patch" as a
+firmware file for modifying the HD-audio setup before initializing the
+codec. This can work basically like the reconfiguration via sysfs in
+the above, but it does it before the first codec configuration.
+
+A patch file is a plain text file which looks like below:
+
+------------------------------------------------------------------------
+ [codec]
+ 0x12345678 0xabcd1234 2
+
+ [model]
+ auto
+
+ [pincfg]
+ 0x12 0x411111f0
+
+ [verb]
+ 0x20 0x500 0x03
+ 0x20 0x400 0xff
+
+ [hint]
+ hp_detect = yes
+------------------------------------------------------------------------
+
+The file needs to have a line `[codec]`. The next line should contain
+three numbers indicating the codec vendor-id (0x12345678 in the
+example), the codec subsystem-id (0xabcd1234) and the address (2) of
+the codec. The rest patch entries are applied to this specified codec
+until another codec entry is given.
+
+The `[model]` line allows to change the model name of the each codec.
+In the example above, it will be changed to model=auto.
+Note that this overrides the module option.
+
+After the `[pincfg]` line, the contents are parsed as the initial
+default pin-configurations just like `user_pin_configs` sysfs above.
+The values can be shown in user_pin_configs sysfs file, too.
+
+Similarly, the lines after `[verb]` are parsed as `init_verbs`
+sysfs entries, and the lines after `[hint]` are parsed as `hints`
+sysfs entries, respectively.
+
+The hd-audio driver reads the file via request_firmware(). Thus,
+a patch file has to be located on the appropriate firmware path,
+typically, /lib/firmware. For example, when you pass the option
+`patch=hda-init.fw`, the file /lib/firmware/hda-init-fw must be
+present.
+
+The patch module option is specific to each card instance, and you
+need to give one file name for each instance, separated by commas.
+For example, if you have two cards, one for an on-board analog and one
+for an HDMI video board, you may pass patch option like below:
+------------------------------------------------------------------------
+ options snd-hda-intel patch=on-board-patch,hdmi-patch

- help
- NILFS2 is a log-structured file system (LFS) supporting continuous
- snapshotting. In addition to versioning capability of the entire
- file system, users can even restore files mistakenly overwritten or
- destroyed just a few seconds ago. Since this file system can keep
- consistency like conventional LFS, it achieves quick recovery after
- system crashes.
-
- NILFS2 creates a number of checkpoints every few seconds or per
- synchronous write basis (unless there is no change). Users can
- select significant versions among continuously created checkpoints,
- and can change them into snapshots which will be preserved for long
- periods until they are changed back to checkpoints. Each
- snapshot is mountable as a read-only file system concurrently with
- its writable mount, and this feature is convenient for online backup.
-
- Some features including atime, extended attributes, and POSIX ACLs,
- are not supported yet.
-
- To compile this file system support as a module, choose M here: the
- module will be called nilfs2. If unsure, say N.

+ bool "Default to 'data=ordered' in ext3"
depends on EXT3_FS
help
- If a filesystem does not explicitly specify a data ordering
- mode, and the journal capability allowed it, ext3 used to
- historically default to 'data=ordered'.
+ The journal mode options for ext3 have different tradeoffs
+ between when data is guaranteed to be on disk and
+ performance. The use of "data=writeback" can cause
+ unwritten data to appear in files after an system crash or
+ power failure, which can be a security issue. However,
+ "data=ordered" mode can also result in major performance
+ problems, including seconds-long delays before an fsync()
+ call returns. For details, see:
- That was a rather unfortunate choice, because it leads to all
- kinds of latency problems, and the 'data=writeback' mode is more
- appropriate these days.
+ http://ext4.wiki.kernel.org/index.php/Ext3_data_mode_tradeoffs
- You should probably always answer 'n' here, and if you really
- want to use 'data=ordered' mode, set it in the filesystem itself
- with 'tune2fs -o journal_data_ordered'.
-
- But if you really want to enable the legacy default, you can do
- so by answering 'y' to this question.
+ If you have been historically happy with ext3's performance,
+ data=ordered mode will be a safe choice and you should
+ answer 'y' here. If you understand the reliability and data
+ privacy issues of data=writeback and are willing to make
+ that trade off, answer 'n'.

+ select CRC32
+ help
+ NILFS2 is a log-structured file system (LFS) supporting continuous
+ snapshotting. In addition to versioning capability of the entire
+ file system, users can even restore files mistakenly overwritten or
+ destroyed just a few seconds ago. Since this file system can keep
+ consistency like conventional LFS, it achieves quick recovery after
+ system crashes.
+
+ NILFS2 creates a number of checkpoints every few seconds or per
+ synchronous write basis (unless there is no change). Users can
+ select significant versions among continuously created checkpoints,
+ and can change them into snapshots which will be preserved for long
+ periods until they are changed back to checkpoints. Each
+ snapshot is mountable as a read-only file system concurrently with
+ its writable mount, and this feature is convenient for online backup.
+
+ Some features including atime, extended attributes, and POSIX ACLs,
+ are not supported yet.
+
+ To compile this file system support as a module, choose M here: the
+ module will be called nilfs2. If unsure, say N.

+ help
+ This is the portion of low virtual memory which should be protected
+ from userspace allocation. Keeping a user from writing to low pages
+ can help reduce the impact of kernel NULL pointer bugs.
+
+ For most ia64, ppc64 and x86 users with lots of address space
+ a value of 65536 is reasonable and should cause no problems.
+ On arm and other archs it should not be higher than 32768.
+ Programs which use vm86 functionality or have some need to map
+ this low address space will need the permission specific to the
+ systems running LSM.

+ * Even though TDM mode can be as part of I2S DAI, but there
+ * are so much difference in configuration and data flow,
+ * it's very ugly to integrate I2S and TDM into a module

+
+
+First, discovery/enumeration of available counters can be done via
+'perf list':
+
+titan:~> perf list
+ [...]
+ kmem:kmalloc [Tracepoint event]
+ kmem:kmem_cache_alloc [Tracepoint event]
+ kmem:kmalloc_node [Tracepoint event]

+ kmem:mm_page_alloc_zone_locked [Tracepoint event]
+ kmem:mm_page_pcpu_drain [Tracepoint event]
+ kmem:mm_page_alloc_extfrag [Tracepoint event]
+
+Then any (or all) of the above event sources can be activated and
+measured. For example the page alloc/free properties of a 'hackbench
+run' are:
+
+ titan:~> perf stat -e kmem:mm_page_pcpu_drain -e kmem:mm_page_alloc
+ -e kmem:mm_pagevec_free -e kmem:mm_page_free_direct ./hackbench 10
+ Time: 0.575
+
+ Performance counter stats for './hackbench 10':
+
+ 13857 kmem:mm_page_pcpu_drain

+ 6025 kmem:mm_pagevec_free
+ 20934 kmem:mm_page_free_direct
+
+ 0.613972165 seconds time elapsed
+
+You can observe the statistical properties as well, by using the
+'repeat the workload N times' feature of perf stat:
+
+ titan:~> perf stat --repeat 5 -e kmem:mm_page_pcpu_drain -e
+ kmem:mm_page_alloc -e kmem:mm_pagevec_free -e

+ 0.643954516 seconds time elapsed ( +- 2.363% )
+
+Furthermore, these tracepoints can be used to sample the workload as
+well. For example the page allocations done by a 'git gc' can be
+captured the following way:
+
+ titan:~/git> perf record -f -e kmem:mm_page_alloc -c 1 ./git gc
+ Counting objects: 1148, done.
+ Delta compression using up to 2 threads.
+ Compressing objects: 100% (450/450), done.
+ Writing objects: 100% (1148/1148), done.
+ Total 1148 (delta 690), reused 1148 (delta 690)
+ [ perf record: Captured and wrote 0.267 MB perf.data (~11679 samples) ]
+
+To check which functions generated page allocations:
+
+ titan:~/git> perf report
+ # Samples: 10646
+ #
+ # Overhead Command Shared Object
+ # ........ ............... ..........................
+ #

+
+Or to see it on a more finegrained level:
+
+titan:~/git> perf report --sort comm,dso,symbol

+
+Furthermore, call-graph sampling can be done too, of page
+allocations - to see precisely what kind of page allocations there
+are:
+
+ titan:~/git> perf record -f -g -e kmem:mm_page_alloc -c 1 ./git gc
+ Counting objects: 1148, done.

+
+Or you can observe the whole system's page allocations for 10
+seconds:
+
+titan:~/git> perf stat -a -e kmem:mm_page_pcpu_drain -e
+kmem:mm_page_alloc -e kmem:mm_pagevec_free -e

+ 73623 kmem:mm_pagevec_free
+ 254115 kmem:mm_page_free_direct
+
+ 10.000591410 seconds time elapsed
+
+Or observe how fluctuating the page allocations are, via statistical
+analysis done over ten 1-second intervals:
+
+ titan:~/git> perf stat --repeat 10 -a -e kmem:mm_page_pcpu_drain -e
+ kmem:mm_page_alloc -e kmem:mm_pagevec_free -e
+ kmem:mm_page_free_direct sleep 1
+
+ Performance counter stats for 'sleep 1' (10 runs):
+
+ 17254 kmem:mm_page_pcpu_drain ( +- 3.709% )
+ 34394 kmem:mm_page_alloc ( +- 4.617% )
+ 7509 kmem:mm_pagevec_free ( +- 4.820% )
+ 25653 kmem:mm_page_free_direct ( +- 3.672% )
+
+ 1.058135029 seconds time elapsed ( +- 3.089% )
+
+Or you can annotate the recorded 'git gc' run on a per symbol basis
+and check which instructions/source-code generated page allocations:
+
+ titan:~/git> perf annotate __GI___fork
+ ------------------------------------------------
+ Percent | Source code & Disassembly of libc-2.5.so
+ ------------------------------------------------
+ :

+ 0.00 : 31a2e95615: 85 c0 test %eax,%eax
+
+( this shows that 83.42% of __GI___fork's page allocations come from
+ the 0x38 system call it performs. )
+
+etc. etc. - a lot more is possible. I could list a dozen of
+other different usecases straight away - neither of which is
+possible via /proc/vmstat.
+
+/proc/vmstat is not in the same league really, in terms of
+expressive power of system analysis and performance
+analysis.
+
+All that the above results needed were those new tracepoints
+in include/tracing/events/kmem.h.
