732Docking / undocking -- /proc/acpi/ibm/dock
733------------------------------------------
734
735Docking and undocking (e.g. with the X4 UltraBase) requires some
736actions to be taken by the operating system to safely make or break
737the electrical connections with the dock.
738
739The docking feature of this driver generates the following ACPI events:
740
741 ibm/dock GDCK 00000003 00000001 -- eject request
742 ibm/dock GDCK 00000003 00000002 -- undocked
743 ibm/dock GDCK 00000000 00000003 -- docked
744
745NOTE: These events will only be generated if the laptop was docked
746when originally booted. This is due to the current lack of support for
747hot plugging of devices in the Linux ACPI framework. If the laptop was
748booted while not in the dock, the following message is shown in the
749logs:
750
751 Mar 17 01:42:34 aero kernel: thinkpad_acpi: dock device not present
752
753In this case, no dock-related events are generated but the dock and
754undock commands described below still work. They can be executed
755manually or triggered by Fn key combinations (see the example acpid
756configuration files included in the driver tarball package available
757on the web site).
758
759When the eject request button on the dock is pressed, the first event
760above is generated. The handler for this event should issue the
761following command:
762
763 echo undock > /proc/acpi/ibm/dock
764
765After the LED on the dock goes off, it is safe to eject the laptop.
766Note: if you pressed this key by mistake, go ahead and eject the
767laptop, then dock it back in. Otherwise, the dock may not function as
768expected.
769
770When the laptop is docked, the third event above is generated. The
771handler for this event should issue the following command to fully
772enable the dock:
773
774 echo dock > /proc/acpi/ibm/dock
775
776The contents of the /proc/acpi/ibm/dock file shows the current status
777of the dock, as provided by the ACPI framework.
778
779The docking support in this driver does not take care of enabling or
780disabling any other devices you may have attached to the dock. For
781example, a CD drive plugged into the UltraBase needs to be disabled or
782enabled separately. See the provided example acpid configuration files
783for how this can be accomplished.
784
785There is no support yet for PCI devices that may be attached to a
786docking station, e.g. in the ThinkPad Dock II. The driver currently
787does not recognize, enable or disable such devices. This means that
788the only docking stations currently supported are the X-series
789UltraBase docks and "dumb" port replicators like the Mini Dock (the
790latter don't need any ACPI support, actually).
791
792
793UltraBay eject -- /proc/acpi/ibm/bay
794------------------------------------
795
796Inserting or ejecting an UltraBay device requires some actions to be
797taken by the operating system to safely make or break the electrical
798connections with the device.
799
800This feature generates the following ACPI events:
801
802 ibm/bay MSTR 00000003 00000000 -- eject request
803 ibm/bay MSTR 00000001 00000000 -- eject lever inserted
804
805NOTE: These events will only be generated if the UltraBay was present
806when the laptop was originally booted (on the X series, the UltraBay
807is in the dock, so it may not be present if the laptop was undocked).
808This is due to the current lack of support for hot plugging of devices
809in the Linux ACPI framework. If the laptop was booted without the
810UltraBay, the following message is shown in the logs:
811
812 Mar 17 01:42:34 aero kernel: thinkpad_acpi: bay device not present
813
814In this case, no bay-related events are generated but the eject
815command described below still works. It can be executed manually or
816triggered by a hot key combination.
817
818Sliding the eject lever generates the first event shown above. The
819handler for this event should take whatever actions are necessary to
820shut down the device in the UltraBay (e.g. call idectl), then issue
821the following command:
822
823 echo eject > /proc/acpi/ibm/bay
824
825After the LED on the UltraBay goes off, it is safe to pull out the
826device.
827
828When the eject lever is inserted, the second event above is
829generated. The handler for this event should take whatever actions are
830necessary to enable the UltraBay device (e.g. call idectl).
831
832The contents of the /proc/acpi/ibm/bay file shows the current status
833of the UltraBay, as provided by the ACPI framework.
834
835EXPERIMENTAL warm eject support on the 600e/x, A22p and A3x (To use
836this feature, you need to supply the experimental=1 parameter when
837loading the module):
838
839These models do not have a button near the UltraBay device to request
840a hot eject but rather require the laptop to be put to sleep
841(suspend-to-ram) before the bay device is ejected or inserted).
842The sequence of steps to eject the device is as follows:
843
844 echo eject > /proc/acpi/ibm/bay
845 put the ThinkPad to sleep
846 remove the drive
847 resume from sleep
848 cat /proc/acpi/ibm/bay should show that the drive was removed
849
850On the A3x, both the UltraBay 2000 and UltraBay Plus devices are
851supported. Use "eject2" instead of "eject" for the second bay.
852
853Note: the UltraBay eject support on the 600e/x, A22p and A3x is
854EXPERIMENTAL and may not work as expected. USE WITH CAUTION!

969 Allow the use of tracepoints as software performance counters.
970
971 When this is enabled, you can create perf counters based on
972 tracepoints using PERF_TYPE_TRACEPOINT and the tracepoint ID
973 found in debugfs://tracing/events/*/*/id. (The -e/--events
974 option to the perf tool can parse and interpret symbolic
975 tracepoints, in the subsystem:tracepoint_name format.)

9First, discovery/enumeration of available counters can be done via
10'perf list':
11
12titan:~> perf list
13 [...]
14 kmem:kmalloc [Tracepoint event]
15 kmem:kmem_cache_alloc [Tracepoint event]
16 kmem:kmalloc_node [Tracepoint event]
17 kmem:kmem_cache_alloc_node [Tracepoint event]
18 kmem:kfree [Tracepoint event]
19 kmem:kmem_cache_free [Tracepoint event]
20 kmem:mm_page_free_direct [Tracepoint event]
21 kmem:mm_pagevec_free [Tracepoint event]
22 kmem:mm_page_alloc [Tracepoint event]
23 kmem:mm_page_alloc_zone_locked [Tracepoint event]
24 kmem:mm_page_pcpu_drain [Tracepoint event]
25 kmem:mm_page_alloc_extfrag [Tracepoint event]
26
27Then any (or all) of the above event sources can be activated and
28measured. For example the page alloc/free properties of a 'hackbench
29run' are:
30
31 titan:~> perf stat -e kmem:mm_page_pcpu_drain -e kmem:mm_page_alloc
32 -e kmem:mm_pagevec_free -e kmem:mm_page_free_direct ./hackbench 10
33 Time: 0.575
34
35 Performance counter stats for './hackbench 10':
36
37 13857 kmem:mm_page_pcpu_drain
38 27576 kmem:mm_page_alloc
39 6025 kmem:mm_pagevec_free
40 20934 kmem:mm_page_free_direct
41
42 0.613972165 seconds time elapsed
43
44You can observe the statistical properties as well, by using the
45'repeat the workload N times' feature of perf stat:
46
47 titan:~> perf stat --repeat 5 -e kmem:mm_page_pcpu_drain -e
48 kmem:mm_page_alloc -e kmem:mm_pagevec_free -e
49 kmem:mm_page_free_direct ./hackbench 10
50 Time: 0.627
51 Time: 0.644
52 Time: 0.564
53 Time: 0.559
54 Time: 0.626
55
56 Performance counter stats for './hackbench 10' (5 runs):
57
58 12920 kmem:mm_page_pcpu_drain ( +- 3.359% )
59 25035 kmem:mm_page_alloc ( +- 3.783% )
60 6104 kmem:mm_pagevec_free ( +- 0.934% )
61 18376 kmem:mm_page_free_direct ( +- 4.941% )
62
63 0.643954516 seconds time elapsed ( +- 2.363% )
64
65Furthermore, these tracepoints can be used to sample the workload as
66well. For example the page allocations done by a 'git gc' can be
67captured the following way:
68
69 titan:~/git> perf record -f -e kmem:mm_page_alloc -c 1 ./git gc
70 Counting objects: 1148, done.
71 Delta compression using up to 2 threads.
72 Compressing objects: 100% (450/450), done.
73 Writing objects: 100% (1148/1148), done.
74 Total 1148 (delta 690), reused 1148 (delta 690)
75 [ perf record: Captured and wrote 0.267 MB perf.data (~11679 samples) ]
76
77To check which functions generated page allocations:
78
79 titan:~/git> perf report
80 # Samples: 10646
81 #
82 # Overhead Command Shared Object
83 # ........ ............... ..........................

100 0.64% git-repack /usr/lib64/libz.so.1.2.3
101
102Or to see it on a more finegrained level:
103
104titan:~/git> perf report --sort comm,dso,symbol
105# Samples: 10646
106#
107# Overhead Command Shared Object Symbol

117 2.99% git /lib64/libc-2.5.so [.] memset
118
119Furthermore, call-graph sampling can be done too, of page
120allocations - to see precisely what kind of page allocations there
121are:
122
123 titan:~/git> perf record -f -g -e kmem:mm_page_alloc -c 1 ./git gc
124 Counting objects: 1148, done.
125 Delta compression using up to 2 threads.
126 Compressing objects: 100% (450/450), done.
127 Writing objects: 100% (1148/1148), done.
128 Total 1148 (delta 690), reused 1148 (delta 690)
129 [ perf record: Captured and wrote 0.963 MB perf.data (~42069 samples) ]
130
131 titan:~/git> perf report -g

156
157Or you can observe the whole system's page allocations for 10
158seconds:
159
160titan:~/git> perf stat -a -e kmem:mm_page_pcpu_drain -e
161kmem:mm_page_alloc -e kmem:mm_pagevec_free -e
162kmem:mm_page_free_direct sleep 10
163
164 Performance counter stats for 'sleep 10':
165
166 171585 kmem:mm_page_pcpu_drain
167 322114 kmem:mm_page_alloc
168 73623 kmem:mm_pagevec_free
169 254115 kmem:mm_page_free_direct
170
171 10.000591410 seconds time elapsed
172
173Or observe how fluctuating the page allocations are, via statistical
174analysis done over ten 1-second intervals:
175
176 titan:~/git> perf stat --repeat 10 -a -e kmem:mm_page_pcpu_drain -e
177 kmem:mm_page_alloc -e kmem:mm_pagevec_free -e
178 kmem:mm_page_free_direct sleep 1
179
180 Performance counter stats for 'sleep 1' (10 runs):
181
182 17254 kmem:mm_page_pcpu_drain ( +- 3.709% )
183 34394 kmem:mm_page_alloc ( +- 4.617% )
184 7509 kmem:mm_pagevec_free ( +- 4.820% )
185 25653 kmem:mm_page_free_direct ( +- 3.672% )
186
187 1.058135029 seconds time elapsed ( +- 3.089% )
188
189Or you can annotate the recorded 'git gc' run on a per symbol basis
190and check which instructions/source-code generated page allocations:
191
192 titan:~/git> perf annotate __GI___fork

207 0.00 : 31a2e95615: 85 c0 test %eax,%eax
208
209( this shows that 83.42% of __GI___fork's page allocations come from
210 the 0x38 system call it performs. )
211
212etc. etc. - a lot more is possible. I could list a dozen of
213other different usecases straight away - neither of which is
214possible via /proc/vmstat.
215
216/proc/vmstat is not in the same league really, in terms of
217expressive power of system analysis and performance
218analysis.
219
220All that the above results needed were those new tracepoints
221in include/tracing/events/kmem.h.
