ARC: perf: ARC 700 PMU doesn't support sampling events 2013-11-15T05:22:28+00:00 Mischa Jonker mjonker@synopsys.com 2013-11-13T15:06:06+00:00 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 cores 2013-11-12T04:15:38+00:00 Mischa Jonker mjonker@synopsys.com 2013-11-07T13:55:11+00:00 0dd450fe13da4aeacc69916ecfe39d3d0b531900 This adds basic perf support for ARC700 cores. Most PERF_COUNT_HW* events are supported now. Signed-off-by: Mischa Jonker <mjonker@synopsys.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
