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
