This is a port of prior work from i915 to support fine-grained CPU-GPU
timestamp correlation. Prior work is linked in this issue:
https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/384

Mesa and Perfetto are the consumers for this and the issue documents the
need for higher accuracy in correlation. 

v2:
- Change commit headers to fixup!
- Fix kernel-doc errors
- Include review comments

v3:
- s/rsvd/pad/ in struct drm_xe_engine_class_instance (Jose)
- Initialize pad

Umesh Nerlige Ramappa (3):
  drm/xe: Fix array bounds check for queries
  drm/xe: Set the correct type for xe_to_user_engine_class
  drm/xe: Correlate engine and cpu timestamps with better accuracy
