[igt-dev] [PATCH i-g-t 0/4] Add i915 blt library + gem_ccs test

[Zbigniew Kempczyński]

Enable DG2+ testing of flatccs.

Idea of library comes from Ayaz, just implementation differs due
to some reasons discovered during different tiling testing.

Currently I used default (0) mocs to avoid kernel differences.
We may change it to UC/WB when kernel interface will be stabilized
and merged.

v2: To unblock DG2 local definition of pciids was added to i915_drm_local.h
