[igt-dev] [PATCH i-g-t v5 0/4] Basic LMEM support in IGT

[Zbigniew Kempczyński]

LMEM enabling in IGT.

v2: Refactoring, addressing issues from previous review.
    Fixing bugs in tests.
v3: Changes according to the review comments.
    Adding gem_mmap__device_coherent(). 
v4: If memory region query is not supported use probe()
    as a fallback to system and device memory regions.
v5: Quickfix - removing override which enforces probe()
