* [PATCH v2] perf vendor events: Update events for Neoverse E1
@ 2022-09-07 15:49 ` Nick Forrington

	Namhyung Kim, linux-arm-kernel

These CPUs contain the same PMU events (as per the Arm Technical
Reference manuals for Cortex A65 and Neoverse E1)

This de-duplicates event data, and avoids issues in previous E1 event
data (not present in A65 data)
* Missing implementation defined events
* Inclusion of events that are not implemented:
  - L1D_CACHE_ALLOCATE
  - SAMPLE_POP
  - SAMPLE_FEED
  - SAMPLE_FILTRATE
  - SAMPLE_COLLISION

V1 -> V2: Remove proposed E1 changes. Use A65 data for A65 and E1 instead
