Subject: [PATCH v5 00/13] Python generated AMD Zen metrics

Generate thirteen sets of additional metrics for AMD zen.  Rapl and
Idle metrics aren't specific to AMD but are placed here for ease and
convenience. Uncore L3 metrics are added along with the majority of
core metrics.

The patches should be applied on top of:
https://lore.kernel.org/lkml/20250829030727.4159703-1-irogers@google.com/

v5. Rebase. Add uop cache hit/miss rates patch. Prefix all metric
    names with lpm_ (short for Linux Perf Metric) so that python
    generated metrics are clearly namespaced.

v4. Rebase.
    https://lore.kernel.org/lkml/20240926174101.406874-1-irogers@google.com/

v3. Some minor code cleanup changes.
    https://lore.kernel.org/lkml/20240314055839.1975063-1-irogers@google.com/

v2. Drop the cycles breakdown in favor of having it as a common
    metric, suggested by Kan Liang <kan.liang@...ux.intel.com>.
