Create tracepoints to track the three major events of a CPU job lifetime: 1. Submission of a `v3d_submit_cpu` IOCTL 2. Beginning of the execution of a CPU job 3. Ending of the execution of a CPU job Signed-off-by: Maíra Canal <mcanal@xxxxxxxxxx> --- drivers/gpu/drm/v3d/v3d_sched.c | 4 +++ drivers/gpu/drm/v3d/v3d_submit.c | 2 ++ drivers/gpu/drm/v3d/v3d_trace.h | 57 ++++++++++++++++++++++++++++++++ 3 files changed, 63 insertions(+) diff --git a/drivers/gpu/drm/v3d/v3d_sched.c b/drivers/gpu/drm/v3d/v3d_sched.c index a32c91b94898..30a88e557217 100644 --- a/drivers/gpu/drm/v3d/v3d_sched.c +++ b/drivers/gpu/drm/v3d/v3d_sched.c @@ -288,8 +288,12 @@ v3d_cpu_job_run(struct drm_sched_job *sched_job) file->start_ns[V3D_CPU] = local_clock(); v3d->queue[V3D_CPU].start_ns = file->start_ns[V3D_CPU]; + trace_v3d_cpu_job_begin(&v3d->drm, job->job_type); + v3d_cpu_job_fn[job->job_type](job); + trace_v3d_cpu_job_end(&v3d->drm, job->job_type); + runtime = local_clock() - file->start_ns[V3D_CPU]; file->enabled_ns[V3D_CPU] += runtime; diff --git a/drivers/gpu/drm/v3d/v3d_submit.c b/drivers/gpu/drm/v3d/v3d_submit.c index 955cf3106fdf..337a15b4b594 100644 --- a/drivers/gpu/drm/v3d/v3d_submit.c +++ b/drivers/gpu/drm/v3d/v3d_submit.c @@ -806,6 +806,8 @@ v3d_submit_cpu_ioctl(struct drm_device *dev, void *data, goto fail; } + trace_v3d_submit_cpu_ioctl(&v3d->drm, cpu_job->job_type); + ret = v3d_job_init(v3d, file_priv, (void *)&cpu_job, sizeof(*cpu_job), v3d_job_free, 0, &se, V3D_CPU); if (ret) diff --git a/drivers/gpu/drm/v3d/v3d_trace.h b/drivers/gpu/drm/v3d/v3d_trace.h index 7aa8dc356e54..06086ece6e9e 100644 --- a/drivers/gpu/drm/v3d/v3d_trace.h +++ b/drivers/gpu/drm/v3d/v3d_trace.h @@ -225,6 +225,63 @@ TRACE_EVENT(v3d_submit_csd, __entry->seqno) ); +TRACE_EVENT(v3d_submit_cpu_ioctl, + TP_PROTO(struct drm_device *dev, enum v3d_cpu_job_type job_type), + TP_ARGS(dev, job_type), + + TP_STRUCT__entry( + __field(u32, dev) + __field(enum v3d_cpu_job_type, job_type) + ), + + TP_fast_assign( + __entry->dev = dev->primary->index; + __entry->job_type = job_type; + ), + + TP_printk("dev=%u, job_type=%d", + __entry->dev, + __entry->job_type) +); + +TRACE_EVENT(v3d_cpu_job_begin, + TP_PROTO(struct drm_device *dev, enum v3d_cpu_job_type job_type), + TP_ARGS(dev, job_type), + + TP_STRUCT__entry( + __field(u32, dev) + __field(enum v3d_cpu_job_type, job_type) + ), + + TP_fast_assign( + __entry->dev = dev->primary->index; + __entry->job_type = job_type; + ), + + TP_printk("dev=%u, job_type=%d", + __entry->dev, + __entry->job_type) +); + +TRACE_EVENT(v3d_cpu_job_end, + TP_PROTO(struct drm_device *dev, enum v3d_cpu_job_type job_type), + TP_ARGS(dev, job_type), + + TP_STRUCT__entry( + __field(u32, dev) + __field(enum v3d_cpu_job_type, job_type) + ), + + TP_fast_assign( + __entry->dev = dev->primary->index; + __entry->job_type = job_type; + ), + + TP_printk("dev=%u, job_type=%d", + __entry->dev, + __entry->job_type) +); + TRACE_EVENT(v3d_cache_clean_begin, TP_PROTO(struct drm_device *dev), TP_ARGS(dev), -- 2.41.0
