Subject: [PATCH 01/20] perf vendors events arm64: Arm Cortex-A5
Add PMU events for Arm Cortex-A5
Add corresponding common events
Update mapfile.csv
Event data based on:
https://github.com/ARM-software/data/tree/master/pmu/cortex-a5.json
which is based on PMU event descriptions from the Arm Cortex-A5 Technical
Reference Manual.
Common event data based on:
https://github.com/ARM-software/data/blob/master/pmu/common_armv9.json
which is based on PMU event descriptions found in the Arm Architecture
Reference Manual:
https://developer.arm.com/documentation/ddi0487/
Mapping data (for mapfile.csv) based on:
https://github.com/ARM-software/data/blob/master/cpus.json
which is based on Main ID Register (MIDR) information found in the Arm
Technical Reference Manuals for individual CPUs.
