Subject: [PATCH v11 6/7] perf jevents: Add support for Arm CMN PMU aliasing
Date:   Wed, 27 Sep 2023 13:59:50 +0800

Currently just add aliases for part of Arm CMN PMU events which
are general and compatible for any SoC and CMN-ANY.

"Compat" value "(434|436|43c|43a).*" means it is compatible with
all CMN600/CMN650/CMN700/Ci700, which can be obtained from
commit 7819e05a0dce ("perf/arm-cmn: Revamp model detection").

The arm-cmn PMU events got from:
