Subject: [PATCH 0/2] perf/x86: various RAPL improvements
Date: Mon, 16 Dec 2013 21:20:22 +0100 [thread overview]
Message-ID: <1387225224-27799-1-git-send-email-eranian@google.com> (raw)
This short patch series provides the following improvements
to the RAPL support for perf_events:
- Intel Haswell Celeron (model 69) support
- support for RAPL PP1 energy counter
The PP1 counter maps to the builtin graphic card for client
processors. The new energy event is:
- name: power/energy-gfx/
- code: 0x4
- unit: Joules
- scaling factor: 2^-32 Joules.
Signed-off-by: Stephane Eranian <eranian@google.com>
