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.

Yeah, that would be possible. The other thing I noticed too in another uncore patch I am preparing is that we could also use that active_entry to avoid tracking association of uncore events to counters to update them in the hrtimer routine. All we need there is the list of active event on the uncore PMU and we iterate over them. ^ permalink raw reply [flat|nested] 8+ messages in thread
