[igt-dev] [PATCH i-g-t v4 0/3] Add GEM_MMAP_OFFSET support in IGT.

[Zbigniew Kempczyński]

Enable GEM_MMAP_OFFSET uAPI.

Series comes from split 'LMEM enabling in IGT'.
Mmap_offset will land before memory region so add support for it.

v2: Change WC -> WB according to review
v3: Remove "local" from i915_drm.h and push dummy commit to it.
    (suggested by Petri).
    Add mmap-offset-close-race test (suggested by Chris).
v4: Additional checks + fixing leak in __gem_mmap__has_wc()
