Apple M2 PMU support

[PATCH 0/2] Apple M2 PMU support

Posted by Janne Grunau 2 years, 6 months ago

This small series adds support for the PMU in Apple M2 cores. The PMU
itself appears to work in the same way as om M1. We still want to add
CPU type specific compatible strings so that we can distinguish counters
in the case they count (slightly) different things on different CPU
uarchs.
