| H A D | v3d_trace.h | diff 55a9b74846ed5e6219c7d81a8e1bf96f25d8ad5e Fri Nov 30 18:57:58 CST 2018 Eric Anholt <eric@anholt.net> 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.
