Varad Gautam	ca26d28bba	drm/vc4: improve throughput by pipelining binning and rendering jobs ... The hardware provides us with separate threads for binning and rendering, and the existing model waits for them both to complete before submitting the next job. Splitting the binning and rendering submissions reduces idle time and gives us approx 20-30% speedup with some x11perf tests such as -line10 and -tilerect1. Improves openarena performance by 1.01897% +/- 0.247857% (n=16). Thanks to anholt for suggesting this. v2: Rebase on the spurious resets fix (change by anholt).

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	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.
