This adds the basic drm dma-buf interface layer, called PRIME. This commit doesn't add any driver support, it is simply and agreed upon starting point so we can work towards merging driver support for the next merge window. Current drivers with work done are nouveau, i915, udl, exynos and omap. The main APIs exposed to userspace allow translating a 32-bit object handle to a file descriptor, and a file descriptor to a 32-bit object handle. The flags value is currently limited to O_CLOEXEC. Acknowledgements: Daniel Vetter: lots of review Rob Clark: cleaned up lots of the internals and did lifetime review. v2: rename some functions after Chris preferred a green shed fix IS_ERR_OR_NULL -> IS_ERR v3: Fix Ville pointed out using buffer + kmalloc v4: add locking as per ickle review v5: allow re-exporting the original dma-buf (Daniel) Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Rob Clark <rob.clark@linaro.org> Reviewed-by: Sumit Semwal <sumit.semwal@linaro.org> Reviewed-by: Inki Dae <inki.dae@samsung.com> Acked-by: Ben Widawsky <benjamin.widawsky@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
