Subject: [RESEND PATCH v2 v4.1-rc8 0/2] drm: prime: Allow exported dma-bufs to be mapped
Date: Fri, 19 Jun 2015 14:52:27 +0100	[thread overview]
Message-ID: <1434721949-25732-1-git-send-email-daniel.thompson@linaro.org> (raw)

This patch set started out as a single patch with a trivial bit of
boilerplate to add dmabuf mmap support to the msm driver. However Rob
Clark pointed out that, rather than keep one of the tricks I had used, it
would be better to change the helpers resulting in this series.

I've tested this both with a rather hacked about Android userspace
and with a fairly small test case run from debian. Both bits of code
currently use dumb buffers.

Thanks to Benjamin Gaignard for his help in finding this bit of code and
to Damien Hobson-Garcia for pointing out that I'd forgotten (since 3.18)
to RESEND these patches.

Dave: I guess its probably too late in the dev. cycle to take this code
      but don't worry, I will try really hard to remember to RESEND it
      for 4.2. ;-)

v2:

* Modified DRM_PRIME_HANDLE_TO_FD to honour the O_RDRW from the user
  and removed code to workaround this from the sti driver (Rob Clark).

* Added a patch to (rather spartanly) document gem_prime_mmap. Only
  tacked into this series 'cos I spotted it was missing when I was
  checking whether I needed to describe DRM_RDRW anywhere.
