Eric Anholt	2c68f1fcfb	drm/vc4: Return an ERR_PTR from BO creation instead of NULL. ... Fixes igt vc4_create_bo/create-bo-0 by returning -EINVAL from the ioctl instead of -ENOMEM. Signed-off-by: Eric Anholt <eric@anholt.net>	2016-02-16 12:20:58 -08:00
Eric Anholt	54aec44ab0	drm/vc4: Fix the clear color for the first tile rendered. ... Apparently in hardware (as opposed to simulation), the clear colors need to be uploaded before the render config, otherwise they won't take effect. Fixes igt's vc4_wait_bo/used-bo-* subtests.

Eric Anholt	d5b1a78a77	drm/vc4: Add support for drawing 3D frames. ... The user submission is basically a pointer to a command list and a pointer to uniforms. We copy those in to the kernel, validate and relocate them, and store the result in a GPU BO which we queue for execution. v2: Drop support for NV shader recs (not necessary for GL), simplify vc4_use_bo(), improve bin flush/semaphore checks, use __u32 style types.
