Subject[PATCH 0/8] ARCv2 port to Linux - (C) perf
Date
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.

This is part of series which adds ARCv2 ISA support to linux.

Please see [1] for prep patches and [2] for actual port. I've CC'ed you
for some of the patches related to barriers, atomic ops in [2].

Some more info at

Please review !

Thx,

ARC: perf: support RAW events
ARCv2: perf: implement "event_set_period" for future use with
interrupts
ARCv2: perf: Support sampling events using overflow interrupts
ARCv2: perf: set usable max period as a half of real max period
ARCv2: perf: implement exclusion of event counting in user or kernel
mode
ARCv2: perf: SMP support
