[PATCH v13 0/7] drm/xe/pmu: PMU interface for Xe

[Lucas De Marchi]

Previous versions: https://patchwork.freedesktop.org/series/139121/

For perf/core: first patch adds a new macro in include/linux/perf_event.h.
If it's ok, I'd like to merge it through the drm branch so we can add the
pmu implementation to the xe driver. I'm also Cc'ing you on the other
patches to show its usage.

For "drm/xe/pmu: Enable PMU interface", previously from several authors,
I squashed several changes I suggested in the past to clean it up and
reduce boilerplate code that resulted from copy-paste from i915. More
detailed changes can be found at
https://gitlab.freedesktop.org/demarchi/xe/-/tags/tip-xe-pmu-v13

Compared to v12 this only has 1 event as Vinay said he will rebase the
frequency event on top. I tested this on Lunar Lake with and without
workload running and the c6 residency seems reasonable.
