[PATCH 0/6][v4]: perf: Make POWER7 events available in sysfs
Make the generic and some POWER7-specific perf events available in sysfs.
These changes mainly extend similar functionality implemented in x86 to
work on POWER architecture as well.
Thanks to input from Stephane Eranian, Robert Richter, Peter Ziljstra
and Jiri Olsa.
Changelog[v4]:
[Jiri Olsa]: Document that multiple event= like terms can be specified
in the 'events' file.
[Jiri Olsa]: Remove the documentation for the 'config format' file
as it is already documented in 'Documentation/ABI/testing/'
[Jiri Olsa]: Move the ABI documentaion from 'stable/' to 'testing/'.
Changelog[v3]:
[Jiri Olsa]: No need to define EVENT_ID, PMU_EVENT_PTR() if used only
once
[Greg KH]: Document the new sysfs interfaces in Documenation/ABI
Changelog[v2]:
[Jiri Olsa] Use PMU_FORMAT_ATTR() rather than duplicating code.
Sukadev Bhattiprolu (6):
perf/Power7: Use macros to identify perf events
perf: Make EVENT_ATTR global
perf/POWER7: Make generic event translations available in sysfs
perf/POWER7: Make some POWER7 events available in sysfs

[PATCH 1/6][v4]: perf/Power7: Use macros to identify perf events
Define and use macros to identify perf events codes This would make it
easier and more readable when these event codes need to be used in more
than one place.

[PATCH 2/6][v4]: perf: Make EVENT_ATTR global
Rename EVENT_ATTR() to PMU_EVENT_ATTR() and make it global so it is
available to all architectures.
Further to allow architectures flexibility, have PMU_EVENT_ATTR() pass
in the variable name as a parameter.
Changelog[v2]
- [Jiri Osla] No need to define PMU_EVENT_PTR()

[PATCH 5/6][v4]: perf: Create a sysfs entry for Power event format
Create a sysfs entry, '/sys/bus/event_source/devices/cpu/format/event'
which describes the format of a POWER cpu.
The format of the event is the same for all POWER cpus at least in
(Power6, Power7), so bulk of this change is common in the code common
to POWER cpus.
This code is based on corresponding code in x86.
Changelog[v2]: [Jiri Osla] Use PMU_FORMAT_ATTR() rather than duplicating it.

[PATCH 6/6][v4]: perf: Document the ABI of perf sysfs entries
This patchset addes two new sets of files to sysfs for POWER architecture.
- perf event config format in /sys/devices/cpu/format/event
- generic and POWER-specific perf events in /sys/devices/cpu/events/
The format of the first file is already documented in:
sysfs-bus-event_source-devices-format
Document the format of the second set of files '/sys/devices/cpu/events/*'
which would also become part of the ABI.
Changelog[v4]:
[Jiri Olsa]: Mention that multiple event= like terms can be specified
in the 'events' file.
[Jiri Olsa]: Remove the documentation for the 'config format' file
as it is already documented in 'Documentation/ABI/testing/'.
[Jiri Olsa]: Move ABI documentation from 'stable/' to 'testing/'
Changelog[v3]:
[Greg KH] Include ABI documentation.

Did this patch go upstream? I don't see it.
If not, please don't merge it.

No. The event format is different on most POWER cpus, in particular it
is different on Power6 and Power7, and will be different again on
Power8.

Hmm, patches 1..4,6 are in linux-tip and Arnaldo's trees but patch 5 is
in neither.

Sigh. The port of this patchset to Power6 has not started yet.
But this patchset does work on Power7 correct ?
If so, and we figure out what happened to patch 5, can we add a patch to
to move the format code to power7-pmu.c ?

I suspect Arnaldo was either waiting for an ACK from Ben, or was
expecting Ben to take it?

It should hardly require a port, it's about five lines. But it doesn't
matter for now.
> But this patchset does work on Power7 correct ?
Yes, and without it the rest of the series is essentially useless. So I
guess it's better than nothing and we should get it in, we can fix it up
later to work across different chips.
Ben can you grab it, it's all arch/powerpc.

Just noticed, it's 20 bits, which is 0-19.

Arnaldo, here is an updated patch. If it is acked by Paul Mackerras,
Michael Ellerman or Ben, will you add it to your tree so the whole
patchset comes from one place ?

Subject: [PATCH] [PATCH 5/6][v4]: perf Create a sysfs format entry for Power7 events
Create a sysfs entry, '/sys/bus/event_source/devices/cpu/format/event'
which describes the format of the POWER7 PMU events.
This code is based on corresponding code in x86.
Changelog[v4]: [Michael Ellerman, Paul Mckerras] The event format is different
for other POWER cpus. So move the code to POWER7-specific,
power7-pmu.c Also, the POWER7 format uses bits 0-19 not 0-20.
Changelog[v2]: [Jiri Osla] Use PMU_FORMAT_ATTR rather than duplicating code.
