[PATCH 0/4] drm/xe: Add psmi support

[Lucas De Marchi]

Add PSMI support to aid debugging. More information about PSMI is in the
second patch. This brings the initial implementation to drm-tip so it's
also easy to debug and enable things early directly upstream.

Opens:
 - Expose the toggle via configfs rather than module param? I'm leaning
   towards this for v2 as we may have multiple cards and want to debug a
   single one. It also matches nicely with the latest configurations we
   added there.
 - Expose the allocation request via configs rather than debugfs: this
   would part ways with configfs being for early-init things. I'm
   leaning against this and just leave that in debugfs
 - Add match for RTP to enable WA only if certain feature is enabled
   (like psmi): I'm leaning towards this so we don't enable WAs that are
   not necessary in normal non-debugging scenarios

I will start preparing a v2 soon with the items above. Opinions on those
are appreciated.
