[PATCH 0/4] drm/xe/xe_drm_client: Add per drm client reset stats

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

Add additional information to drm client so it can report the last 50
exec queues to have been banned on it, as well as the last pagefault
seen when said exec queues were banned. Since we cannot reasonably
associate a pagefault to a specific exec queue, we currently report the
last seen pagefault on the associated hw engine instead.

The last pagefault seen per exec queue is saved to the hw engine, and the
pagefault is updated during the pagefault handling process in
xe_gt_pagefault. The last seen pagefault is reset when the engine is
reset because any future exec queue bans likely were not caused by said
pagefault after the reset.

Also add a tracker that counts the number of times the drm client has
experienced an engine reset.
