[PATCH v3 3/4] drm/sched: cleanup gpu_scheduler trace events

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Print identifiers instead of pointers:
* "fence=%p" is replaced by "fence=(context:%llu, seqno:%lld)" to have a
coherent way to print the fence. A possible follow up change would be
to use the same format in traces/../dma-fence.h.
* "entity=%p" is removed because the fence's context is already an
identifier of the job owner.
