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?
Changes from v1:
- rebased from drm-next branch of
git://people.freedesktop.org/~airlied/linux
- fix to check whether gem_prime_mmap field is NULL
from "drm: add mmap function to prime helpers" commit
Joonyoung Shim (3):
drm: add mmap function to prime helpers
drm/cma: add low-level hook functions to use prime helpers
drm/cma: remove GEM CMA specific dma_buf functionality
