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 ?
I'm not sure it's better to choose which way.
Dave, how we should do about that problem?
