-Subject: [PATCH 566/806] drm/v3d: Add more tracepoints for V3D GPU rendering.
-
-The core scheduler tells us when the job is pushed to the scheduler's
-queue, and I had the job_run functions saying when they actually queue
-the job to the hardware. By adding tracepoints for the very top of
-the ioctls and the IRQs signaling job completion, "perf record -a -e
-v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty
-decent timeline.
