Metrics in the perf tool come in via json. Json doesn't allow
comments, line breaks, etc. making it an inconvenient way to write
metrics. Further, it is useful to detect when writing a metric that
the event specified is supported within the event json for a model.
These patches introduce infrastructure and fixes for the addition of
metrics written in python for Arm64, AMD Zen and Intel CPUs. Later
patches will introduce the metrics split apart by the vendor.
v4. Rebase and small Build/Makefile tweak
v3. Some code tidying, make the input directory a command line
argument, but no other functional or output changes.
v2. Fixes two type issues in the python code but no functional or
output changes.
