drm/vgem: drop DRIVER_PRIME (v2)

2015-05-26T06:17:06Z

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 Acked-by: Daniel Vetter Signed-off-by: Rob Clark Signed-off-by: Dave Airlie

drm/vgem: implement virtual GEM

2015-04-01T23:21:48Z

This patch implements the virtual GEM driver with PRIME sharing which allows vgem to import a gem object from other drivers for the purpose of mmap-ing them to userspace. The mmap is done using the mmap operation exported by other drivers. v2: remove platform_device and do not attach to dma bufs v3: use drm helpers for get/put pages v4: correct dumb create pitch Reviewed-by: Rob Clark (v3) Reviewed-by: Stéphane Marchesin (v3) Signed-off-by: Adam Jackson Signed-off-by: Ben Widawsky Signed-off-by: Zach Reizner Signed-off-by: Dave Airlie
