[RFC,00/10] drm/i915: Implement range-based TLB

Message

Cavitt, Jonathan Oct. 10, 2023, 6:44 p.m. UTC

Implement range-based TLB invalidations on top of GuC-based TLB
invalidations.  This is the future plan for GuC-based TLB
invalidations because it helps improve performance over performing
full tlb invalidations all the time.

Jonathan Cavitt (7):
  drm/i915: Add GuC TLB Invalidation device info flags
  drm/i915/guc: Add CT size delay helper
  drm/i915: No TLB invalidation on suspended GT
  drm/i915: No TLB invalidation on wedged GT
  drm/i915/gt: Increase sleep in gt_tlb selftest sanitycheck
  drm/i915: Enable GuC TLB invalidations for MTL
  drm/i915: Use selective tlb invalidations where supported

Prathap Kumar Valsan (3):
  drm/i915: Define and use GuC and CTB TLB invalidation routines
  drm/i915: Define GuC Based TLB invalidation routines
  drm/i915: Add generic interface for tlb invalidation
