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 - www.synopsys.com/dw/ipdir.php?ds=arc-hs38-processor - http://news.synopsys.com/2014-10-14-New-DesignWare-ARC-HS38-Processor-Doubles-Performance-for-Embedded-Linux-Applications - http://www.embedded.com/electronics-news/4435975/Synopsys-ARC-HS38-core-gives-2X-boost-to-Linux-based-apps
Please review !
Thx, -Vineet

Alexey Brodkin (6): 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
Vineet Gupta (2): ARC: perf: cap the number of counters to hardware max of 32 ARCv2: perf: Finally introduce HS perf unit
