Umesh Nerlige Ramappa 7793d00d1b drm/xe: Correlate engine and cpu timestamps with better accuracy
Perf measurements rely on CPU and engine timestamps to correlate
events of interest across these time domains. Current mechanisms get
these timestamps separately and the calculated delta between these
timestamps lack enough accuracy.

To improve the accuracy of these time measurements to within a few us,
add a query that returns the engine and cpu timestamps captured as
close to each other as possible.

Mesa MR: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/24591

v2:
- Fix kernel-doc warnings (CI)
- Document input params and group them together (Jose)
- s/cs/engine/ (Jose)
- Remove padding in the query (Ashutosh)
