[Intel-gfx] [PATCH 0/4] drm/i915: Untangle execlist tracking

[Nick Hoath]

This patchset merges execlist queue items in to gem requests. It does this by 
using the reference count added by the "Replace seqno values with
request structures" patchset to ensure that the gem request is available for
the whole execlist submission lifespan.

v2: merge intel_ctx_submit_request and drm_i915_gem_request, rebase changes &
   add cover letter

v3: Rebase over upstreamed "Replace seqno values with request structures" and
add overzealous freeing fix.

Issue: VIZ-4274

Nick Hoath (4):
  drm/i915: execlist request keeps ptr/ref to gem_request
  drm/i915: Removed duplicate members from submit_request
  drm/i915: Remove FIXME_lrc_ctx backpointer
  drm/i915: Subsume intel_ctx_submit_request in to drm_i915_gem_request
