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?
There you go (and sorry for the late reply)

By the way, between the initial version of the GEM CMA PRIME patch and the version that got merged in v3.10, commit 011c2282c74db120f01a8414edc66c3f217f5511 ("drm: prime: fix refcounting on the dmabuf import error path") was introduced. The GEM CMA PRIME code in v3.10 thus has a refcounting bug :-(
Should this patch set go to -stable, or should we cook up a special fix ?
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
