[PATCH] perf vendor events: Add missing Neoverse V1 events

[PATCH] perf vendor events: Add missing Neoverse V1 events

[Nick Forrington]

Based on updated data from:
https://github.com/ARM-software/data/blob/master/pmu/neoverse-v1.json

which is based on PMU event descriptions from the Arm Neoverse V1
Technical Reference Manual.

This adds the following missing events:
ASE_INST_SPEC
SVE_INST_SPEC
SVE_PRED_SPEC
SVE_PRED_EMPTY_SPEC
SVE_PRED_FULL_SPEC
SVE_PRED_PARTIAL_SPEC
SVE_LDFF_SPEC
SVE_LDFF_FAULT_SPEC
FP_SCALE_OPS_SPEC
FP_FIXED_OPS_SPEC

It also moves REMOTE_ACCESS from other.json to memory.json.

Any specific reason why? I see that neoverse n2 and a76-n1 still use 
"other" json for REMOTE_ACCESS. Nicer to be consistent.

Thanks John, I agree on consistency.

I think memory is a better categorisation (for all CPUs), and this is 
consistent with what I submitted for various Cortex CPUs a while back.

I'd be happy to remove the REMOTE_ACCESS change here and update (or not) 
REMOTE_ACCESS for Neoverse separately.

Were those patches processed or is some still outstanding?

So, how should we proceed?

To me it would be better to just update the categorization of the 
REMOTE_ACCESS event for all cortex cores separately and just add the 
missing Neoverse v1 events here.

Thanks,
John

Those were processed.

(REMOTE_ACCESS appears in memory.json for the Cortex JSON files)

I'll update this patch to remove the REMOTE_ACCESS change, and submit a 
separate patch to make REMOTE_ACCESS categorisation consistent across 
all CPUs.
