[PATCH 07/13] drivers/perf: apple_m1: Add Apple M4 Series Support
From: Myria Sarvay via B4 Relay
Date: Tue Nov 03 2026 - 05:59:35 EST
From: Myria Sarvay <myrialsarvay@xxxxxxxxx>
Add support for the CPU PMU found in the various M4 SoCs. This PMU is
almost exactly the same as the M3 PMU, just with different event
encodings.
One notable difference, is the addition of the various ARM_* events,
which appear to implement the PMUv3 specific events that the arm PMU
specification provides. Hook them up with the various perf events so
that more can easily be counted on M4+ devices.
