[PATCH 0/2] Export POWER8 PMU raw event codes through sysfs

[PATCH 0/2] Export POWER8 PMU raw event codes through sysfs

[Anshuman Khandual]

	This patchset adds some missing event list for POWER7 PMU raw
events which are exported through sysfs interface. Also adds a new
set of raw PMU events list for POWER8. I have completed some amount
of initial testing to verify the working of POWER8 raw event codes
through sysfs.

Before the patch
================
directory contents: /sys/bus/event_source/devices/cpu/
format  perf_event_mux_interval_ms power  subsystem  type  uevent

After the patch
===============
(1) directory contents: /sys/bus/event_source/devices/cpu/
'events'  format  perf_event_mux_interval_ms power  subsystem  type  uevent

(2) contents inside new directory: /sys/bus/event_source/devices/cpu/events/

[PATCH 1/2] power7, perf: Make some new raw event codes available in sysfs

[Anshuman Khandual]

This patch adds some more raw event codes into the existing list
of event codes present in power7-events-list.h file. This tries
to complete the list of events supported in Power7 and matches
the raw event list with libpfm4 library.

It's a bit annoying, but you also need to update the "ABI" document:

  Documentation/ABI/testing/sysfs-bus-event_source-devices-events

Please do so and resend.

What is annoying ? you need to be specific.

The events listed under the following heading are events required to do
CPI analysis.

+EVENT(PM_THRD_2_CONC_RUN_INSTR,               0x40062)

+EVENT(PM_THRD_4_RUN_CYC,                      0x40060)

will be helpful in CPI stack analysis and should be part of the ABI
documentation file. If it does, I will be glad to add them.

It's annoying that we have to update the ABI document.

No they are not, it doesn't say that anywhere in the file.

It happens that the events in there *now* are the CPI events, but that's because
they are the only ones that have been added.

All events that appear in /sys/devices/cpu/events on powerpc should be listed
in the file.

Done, sent out the V2 version of the patch for POWER7 adding all the sysfs exported
raw events into the ABI documentation file.

[PATCH 2/2] power8, perf: Export raw event codes through sysfs interface

[Anshuman Khandual]

This patch exports a set of POWER8 PMU raw event codes through
sysfs interface. Right now the raw event set matches the entire
set of POWER8 events found in libpfm4 library.
