ARC: perf: ARC 700 PMU doesn't support sampling events2013-11-15T05:22:28ZMischa Jonker2013-11-13T15:06:06Zurn:sha1:230c4aadcc394fb48d865a1cd96c8725dabad56d
The ARC 700 does not have an interrupt associated with it, and as
such it cannot trigger when a counter overflows. As the counters are
48 bit, it will usually take at least 100 days before a counter
overflows, so for mere counting of events, there is no problem.
Sampling is not supported though.

ARC: Add perf support for ARC700 cores2013-11-12T04:15:38ZMischa Jonker2013-11-07T13:55:11Zurn:sha1:0dd450fe13da4aeacc69916ecfe39d3d0b531900
This adds basic perf support for ARC700 cores. Most PERF_COUNT_HW* events
are supported now.
