[PATCH 1/6][v3] 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][v3] 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[v3]
- [Jiri Olsa] No need to define PMU_EVENT_PTR()

[PATCH 5/6][v3] 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 Olsa] Use PMU_FORMAT_ATTR() rather than duplicating it.

[PATCH 6/6][v3] perf: Document the ABI of perf sysfs entries
This patchset addes two new sets of files to sysfs:
- generic and POWER-specific perf events in /sys/devices/cpu/events/
- perf event config format in /sys/devices/cpu/format/event
Document the format of these files which would become part of the ABI.
Changelog[v3]:
[Greg KH] Include ABI documentation.

hm, we already already 'format' definition but in testing section
(and we are missing 'events' definition there.. my bad)
anyway, after reading Documentation/ABI/README looks like we
should go for 'testing' section with this as well.. stable
seems scary at this point ;-)

I see that file now ! I have removed that documentation from my patch.

Agree.
Here is the updated patch.
---
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:
Documentation/ABI/testing/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[v3.1]:
(small changes to this one patch).
[Jiri Olsa]: Remove the documentation for the 'config format' file
as it is already documented.
[Jiri Olsa]: Move the documentation of 'events' also to 'testing/'
Changelog[v3]:
[Greg KH] Include ABI documentation.

Maybe it'd worth to mention, that it does not need to be just 'event',
but anything from /sys/bus/event_source/devices/<dev>/format directory,
like
The can be multiple terms like 'event=0xNNNN' specified
and separated with comma. All available terms are located
in /sys/bus/event_source/devices/<dev>/format file.
Please feel free to rephrase or use proper English ;-)
otherwise it's ok,

Subject: [PATCH] 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[v3.2]: (small changes to this one patch).
[Jiri Olsa]: Mention that multiple event= like terms can be specified
in the 'events' file.
Changelog[v3.1]:
(small changes to just this one patch).
[Jiri Olsa]: Remove the documentation for the 'config format' file
as it is already documented in 'Documentation/ABI/testing/'.
[Jiri Olsa]: Move the documentation of 'events' also to 'testing'
from 'stable'.
Changelog[v3]:
[Greg KH] Include ABI documentation.

Ok, I'll wait for Jiri's final acked-by, then you can resubmit the patch
series and I'll apply it to my perf/core branch.

Your patch is good, but raises the question why we're using L1 events
for HW_CACHE.
AFAICS on Intel they use 0x42fe/0x412e, which are last-level-cache (LLC)
events.
PMU name : ix86arch (Intel X86 architectural PMU)
Name : LLC_REFERENCES
Desc : count each request originating from the core to
reference a cache line in the last level cache. The count may
include speculation, but excludes cache line fills due to
hardware prefetch
Code : 0x4f2e
PMU name : ix86arch (Intel X86 architectural PMU)
Name : LLC_MISSES
Desc : count each cache miss condition for references to the
last level cache. The event count may include speculation, but
excludes cache line fills due to hardware prefetch
Code : 0x412e
That would seem to more closely match our PM_L3_LD_HIT/MISS?
cheers
