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).
Signed-off-by: Rob Clark robdclark@gmail.com --- 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..
