[PATCH v2 3/6] drm/xe: Add helper to accumulate exec queue runtime
From: Umesh Nerlige Ramappa Add a helper to accumulate per-client runtime of all its exec queues. Currently that is done in 2 places: 1. when the exec_queue is destroyed 2. when the sched job is completed Signed-off-by: Umesh Nerlige Ramappa Signed-off-by: Lucas De Marchi --- drivers/gpu/drm/xe/xe_device_types.h | 9 +++ drivers/gpu/drm/xe/xe_exec_queue.c | 37 drivers/gpu/drm/xe/xe_exec_queue.h | 1 + drivers/gpu/drm/xe/xe_sched_job.c| 2 ++ 4 files changed, 49 insertions(+) diff --git a/drivers/gpu/drm/xe/xe_device_types.h b/drivers/gpu/drm/xe/xe_device_types.h index 2e62450d86e1..33d3bf93a2f1 100644 --- a/drivers/gpu/drm/xe/xe_device_types.h +++ b/drivers/gpu/drm/xe/xe_device_types.h @@ -547,6 +547,15 @@ struct xe_file { struct mutex lock; } exec_queue; + /** +* @runtime: hw engine class runtime in ticks for this drm client +* +* Only stats from xe_exec_queue->lrc[0] are accumulated.
