[PATCH 0/2] drivers/perf: hisi: Updates for HiSilicon uncore PMUs

Posted by Yushan Wang 1 month, 3 weeks ago

This patchset added support of ITS PMU, and new version of MN PMU.

ITS PMU supports counting number and latency of interrupts by catagory,
and statistics of micro-ops of ITS.

The new version of MN PMU added cycles event, to be used for MN metric
computing.
