[PATCH v2 0/2] perf/x86: various RAPL improvements and fixes
From: Stephane Eranian
Date: Wed Jan 08 2014 - 05:16:08 EST
This short patch series provides the following improvements
to the RAPL support for perf_events:
- support for RAPL PP1 energy counter
- fix struct perf_event active_list field initialization
The PP1 counter maps to the builtin graphic card for client
processors. that is why it is called energy-gpu.
The new energy event is:
- name: power/energy-gpu/
- code: 0x4
- unit: Joules
- scaling factor: 2^-32 Joules.
In v2, we renamed energy-pp1 to energy-gpu. We dropped the Haswell
Celeron patch because it is committed already. But we add a fix for
the broken initialization of the active_entry list.
