drm/amdgpu: Rename entity cleanup finctions.

drm/amdgpu: move amdgpu_ctx_mgr_entity_fini to f_ops flush hook (V4)

2018-06-15T17:20:33Z

With this we can now terminate jobs enqueue into SW queue the moment the task is being killed instead of waiting for last user of drm file to release it. Also stop checking for kref_read(&ctx->refcount) == 1 when calling drm_sched_entity_do_release since other task might still hold a reference to this entity but we don't care since KILL means terminate job submission regardless of what other tasks are doing. v2: Use returned remaining timeout as parameter for the next call. Rebase. v3: Switch to working with jiffies. Streamline remainder TO usage. Rebase. v4: Rebase. Signed-off-by: Andrey Grodzovsky Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Skip drm_sched_entity related ops for KIQ ring.

2018-05-18T21:08:16Z

Following change 75fbed2 we never initialize or use the GPU scheduler for KIQ and hence we need to skip KIQ ring when iterating amdgpu_ctx's scheduler entites. Signed-off-by: Andrey Grodzovsky Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/gpu-sched: fix force APP kill hang(v4)

2018-05-15T18:43:17Z

issue: there are VMC page fault occurred if force APP kill during 3dmark test, the cause is in entity_fini we manually signal all those jobs in entity's queue which confuse the sync/dep mechanism: 1)page fault occurred in sdma's clear job which operate on shadow buffer, and shadow buffer's Gart table is cleaned by ttm_bo_release since the fence in its reservation was fake signaled by entity_fini() under the case of SIGKILL received. 2)page fault occurred in gfx' job because during the lifetime of gfx job we manually fake signal all jobs from its entity in entity_fini(), thus the unmapping/clear PTE job depend on those result fence is satisfied and sdma start clearing the PTE and lead to GFX page fault. fix: 1)should at least wait all jobs already scheduled complete in entity_fini() if SIGKILL is the case. 2)if a fence signaled and try to clear some entity's dependency, should set this entity guilty to prevent its job really run since the dependency is fake signaled. v2: splitting drm_sched_entity_fini() into two functions: 1)The first one is does the waiting, removes the entity from the runqueue and returns an error when the process was killed. 2)The second one then goes over the entity, install it as completion signal for the remaining jobs and signals all jobs with an error code. v3: 1)Replace the fini1 and fini2 with better name 2)Call the first part before the VM teardown in amdgpu_driver_postclose_kms() and the second part after the VM teardown 3)Keep the original function drm_sched_entity_fini to refine the code. v4: 1)Rename entity->finished to entity->last_scheduled; 2)Rename drm_sched_entity_fini_job_cb() to drm_sched_entity_kill_jobs_cb(); 3)Pass NULL to drm_sched_entity_fini_job_cb() if -ENOENT; 4)Replace the type of entity->fini_status with "int"; 5)Remove the check about entity->finished.

drm: move amd_gpu_scheduler into common location

2017-12-07T16:51:56Z

This moves and renames the AMDGPU scheduler to a common location in DRM in order to facilitate re-use by other drivers. This is mostly a straight forward rename with no code changes. One notable exception is the function to_drm_sched_fence(), which is no longer a inline header function to avoid the need to export the drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.
