[PATCH 0/5] drm/xe: More fb pinning optimizations.

[Maarten Lankhorst]

This reduces the latency of pinning framebuffers by
re-using the previous mapping, if available.

Additionally, DPT is preallocated when creating the FB, instead
of performing a bo allocation on every pin.

Maarten Lankhorst (5):
  drm/xe/display: Preparations for preallocating dpt bo
  drm/xe: Use simple xchg to cache DPT
  drm/xe: Remove safety check from __xe_ttm_stolen_io_mem_reserve_stolen
  drm/xe/display: Prevent overwriting original GGTT when taking over
    initial FB.
  drm/xe/display: Re-use display vmas when possible
