perf: POWER8: Allow specifying Power PMU events by name rather than raw codes

[bugproxy]

== Comment: #0 - Sukadev Bhattiprolu <email address hidden> - 2015-10-19 20:45:40 ==

Power processor provides the ability to monitor a large number of Performance
Monitoring events. However the linux kernel/perf tool requires that a vast majority
of these events be specified by their raw codes:

         perf stat -e r100f2 sleep 1

We would instead like to be able to specify the events by its name:

       perf stat -e pm_1plus_ppc_cmpl sleep 1

where the event name name 'pm_1plus_ppc_cmpl' is defined in
the POWER PMU specs

Here is a pointer to a newer version of the patch set:

No, no comments yet from maintainer, so patches still stuck. Yes we could
re-target to 16.10 for now.

The patches are upstream now, and I understand that it will be integrate into 17.04 without any requirement, since 17.04 will rebase to a later kernel than the current upstream.

[Manoj Iyer (manjo)]

Leann, could you pls close this out once the patch is pulled into 17.04 ?
