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. v2: also drop the dead code [airlied: Okay I'm convinced this API could have a lot of use cases that are really really bad, yes the upload use case is valid however that isn't the only use case enabled, and if we allow all the other use cases, people will start to (ab)use them, and then they'll be ABI and my life will get worse, so disable PRIME for now] Acked-by: Thomas Hellstrom <thellstrom@vmware.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
