Cover letter [PATCH v2 0/3] drm/cma: use prime helpers instead GEM CMA specific dma_buf functionality
Hello,
This is the second version patchset.
GEM CMA supports dma_buf but it needs GEM CMA specific functionality for dma_buf. We can use prime helpers for dma_buf by commit 89177644a7b6306e6084a89eab7e290f4bfef397 "drm: add prime helpers", so this patchset is to replace from using GEM CMA specific functions to using prime helpers.
To Laurent,
It is merged a patch to cache mapping from DRM Prime, can this patchset get your ack?
