Hi Peter,
This mini-series adds perf support for ARCv2 based cores, which brings in
overflow interupts and SMP. Additionally now raw events are supported as well.
Please review !
Compared to v2 this series has:
[1] Removed patch with raw-events support.
It needs some rework and let's then discuss it separately.
Still I plan to send it shortly.
[2] Merged "set usable max period as a half of real max period" into
"implement "event_set_period".
[3] Fixed arc_pmu_event_set_period() in regard of incorrect
"hwc->period_left" setup.
[4] Moved interrupts enabling from arc_pmu_add() to arc_pmu_start()
Compared to v1 this series has:
[1] Addressed review comments
[2] More verbose commit messages and comments in sources
[3] Minor cosmetics
Thanks,
Alexey
