Subject: [PATCH v4 00/22] Python generated Intel metrics

Generate twenty sets of additional metrics for Intel. Rapl and Idle
metrics aren't specific to Intel but are placed here for ease and
convenience. Smi and tsx metrics are added so they can be dropped from
the per model json files. There are four uncore sets of metrics and
eleven core metrics. Add a CheckPmu function to metric to simplify
detecting the presence of hybrid PMUs in events. Metrics with
experimental events are flagged as experimental in their description.

The patches should be applied on top of:
https://lore.kernel.org/lkml/20240926174101.406874-1-irogers@google.com/

v4. Experimental metric descriptions. Add mesh bandwidth metric. Rebase.
v3. Swap tsx and CheckPMU patches that were in the wrong order. Some
    minor code cleanup changes. Drop reference to merged fix for
    umasks/occ_sel in PCU events and for cstate metrics.
v2. Drop the cycles breakdown in favor of having it as a common
    metric, spelling and other improvements suggested by Kan Liang
    <kan.liang@...ux.intel.com>.
