drm/amd/scheduler: Mark amdgpu_sched_ops const

2016-05-05T00:20:05+00:00

This marks the struct amdgpu_sched_ops const and
adjusts amd_sched_init to take a const pointer
for the ops param. The ops member of
struct amd_gpu_scheduler is also changed to const.

drm/amdgpu: use ref to keep job alive

2016-05-02T19:20:07+00:00

this is to fix fatal page fault error that occured if:
job is signaled/released after its timeout work is already
put to the global queue (in this case the cancel_delayed_work
will return false), which will lead to NX-protection error
page fault during job_timeout_func.

drm/amdgpu: rework TDR in scheduler (v2)

2016-05-02T19:19:57+00:00

Add two callbacks to scheduler to maintain jobs, and invoked for
job timeout calculations. Now TDR measures time gap from
job is processed by hw.

v2:
fix typo

drm/amdgpu: get rid of incorrect TDR

2016-05-02T19:19:42+00:00

original time out detect routine is incorrect, cuz it measures
the gap from job scheduled, but we should only measure the
gap from processed by hw.

drm/amdgpu: put job to list before done

2016-05-02T19:17:53+00:00

the mirror_list will be used for later time out detect
feature.  This is needed to properly detect a GPU
timeout with the scheduler.

drm/amdgpu: delay job free to when it's finished (v2)

2016-05-02T19:17:41+00:00

for those jobs submitted through scheduler, do not
free it immediately after scheduled, instead free it
in global workqueue by its sched fence signaling
callback function.

v2:
call uf's bo_undef after job_run()
call job's sync free after job_run()
no static inline __amdgpu_job_free() anymore, just use
kfree(job) to replace it.

drm/amdgpu: RCU protected amd_sched_fence_release

Fences must be freed RCU protected, otherwise the reservation_object_*_rcu()

drm/amdgpu: drop a dummy wakeup scheduler

2016-02-10T19:17:02+00:00

since the dependency job is also scheduled by the same
scheduler with the job depended on it, no need to
call wake up scheduler when the dep is scheduled.
