[PATCH v14 00/25] drm/i915: GEM/GuC Interrupts/Suspend/Resume/Reset fixes and restructuring

[Sagar Arun Kamble]

This series addresses following features/fixes:
1. Restructuring to control GuC interrupts from guc.c functions
2. Making GuC interrupts enable/disable reference based and tying up with
   Logging at all places.
3. Handle suspend/resume/reset for GuC interrupts.
4. Logging fixes about RPM wakeref and skipping relay release during
   submission_fini.
5. GEM/GuC drm and runtime suspend/resume restructuring.
6. Runtime PM interrupt fix along resume path.
7. Handle GGTT invalidate and load status on reset.
8. Handle load status on resume from sleep with need to reload GuC
   and related fixes.

GuC suspend/resume is missing functionality to evict/acquire doorbells
across suspend cycle and that is marked as TODO.

I am keeping these many patches together in single series as most
of them are interrelated w.r.t suspend/resume/reset. Have arranged
them as per feature/fix need/chronology as I have thought of. If
needed, based on review will bring the important and independent
patches earlier in the series.
