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.
