Subject: [PATCH] drm/vgem: drop DRIVER_PRIME
Date: Thu, 21 May 2015 10:53:25 -0400	[thread overview]
Message-ID: <1432220005-24463-1-git-send-email-robdclark@gmail.com> (raw)

For actual sharing of buffers with other drivers (ie. actual hardware)
we'll need to pimp things out a bit better to deal w/ caching, multiple
memory domains, etc.  See thread:

  http://lists.freedesktop.org/archives/dri-devel/2015-May/083160.html

But for the llvmpipe use-case this isn't a problem.  Nor do we really
need prime/dri3 (dri2 is sufficient).  So until the other issues are
sorted lets remove DRIVER_PRIME.

NOTE this ends up leaving some basically dead code for prime import/
export (mostly because I was rushing to send this before a meeting).

This is an alternative to removing vgem completely for 4.1, so that
llvmpipe work can get started in parallel with sorting out the other
issues for sw + hw access..
