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.
