[PATCH v2 3/4] perf vendor events arm64: Reference common and uarch events for Ampere eMag
From: John Garry
Date: Thu Jan 28 2021 - 07:06:55 EST
Reduce duplication in the JSONs by referencing standard events from
armv8-common-and-microarch.json
In general the "PublicDescription" fields are not modified when somewhat
significantly worded differently than the standard.
Apart from that, description and names for events slightly different to
standard are changed (to standard) for consistency.
Note that names for events 0x34 and 0x35 are non-standard and remain
unchanged. Those events came from the following originally:
