[PATCH v1 0/2] perf mem: Support multiple Arm SPE PMUs

Posted by Leo Yan 1 year, 5 months ago

This patch series is to enable multiple Arm SPE PMUs.

The patch 01 is to enable multiple Arm SPE PMUs. The second patch is to
print out warning if not all CPUs support memory events, this can give
users a hint that the memory profiling is absent on some CPUs.
