[PATCH v4 3/4] perf vendor events: Add alias for Arm CMN PMU events.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently just add alias 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.
