Hi Dave, Today's linux-next merge of the drm tree got a conflict in: drivers/gpu/drm/amd/scheduler/gpu_scheduler.c between commit: c94501279bb191c ("Revert "drm/amdgpu: discard commands of killed processes"") from Linus' tree (it even made it into -rc6 over a week ago!) and the fixes it explicitly identifies from the drm tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. diff --cc drivers/gpu/drm/amd/scheduler/gpu_scheduler.c index 38cea6fb25a8,e4d3b4ec4e92..000000000000 --- a/drivers/gpu/drm/amd/scheduler/gpu_scheduler.c +++ b/drivers/gpu/drm/amd/scheduler/gpu_scheduler.c @@@ -208,14 -209,34 +209,35 @@@ void amd_sched_entity_fini(struct amd_g if (!amd_sched_entity_is_initialized(sched, entity)) return; + /** * The client will not queue more IBs during this fini, consume existing - * queued IBs or discard them on SIGKILL + * queued IBs */ - wait_event(sched->job_scheduled, amd_sched_entity_is_idle(entity)); + if ((current->flags & PF_SIGNALED) && current->exit_code == SIGKILL) + r = -ERESTARTSYS; + else + r = wait_event_killable(sched->job_scheduled, + amd_sched_entity_is_idle(entity)); + amd_sched_entity_set_rq(entity, NULL); + if (r) { + struct amd_sched_job *job; + + /* Park the kernel for a moment to make sure it isn't processing + * our enity. + */ + kthread_park(sched->thread); + kthread_unpark(sched->thread); + while (kfifo_out(&entity->job_queue, &job, sizeof(job))) { + struct amd_sched_fence *s_fence = job->s_fence; + amd_sched_fence_scheduled(s_fence); + dma_fence_set_error(&s_fence->finished, -ESRCH); + amd_sched_fence_finished(s_fence); + dma_fence_put(&s_fence->finished); + sched->ops->free_job(job); + } - amd_sched_rq_remove_entity(rq, entity); + } kfifo_free(&entity->job_queue); }
