drm/sched: Create a fake device for KUnit tests

2026-09-08T12:25:54+00:00

The DRM scheduler KUnit tests pass NULL for the dev field in drm_sched_init_args, which NULL-pointer dereferences in the drm_sched_job trace event via dev_name() on sched->dev. Give the mock scheduler a device with kunit_device_register(), which is also cleaned up at test exit. A per-function counter keeps the device names unique, since some tests create several mock schedulers.

drm/sched: Remove redundant entity->rq initialization and checks

2026-06-10T06:18:49+00:00

Commit 28c5bf28763d ("drm/sched: Disallow initializing entities with no schedulers") failed to notice clearing of entity->rq in drm_sched_entity_init() is now redundant and can be removed. Given that entity->rq can now never be NULL, we also remove two impossible checks, from drm_sched_entity_kill() and drm_sched_entity_flush() respectively. Similarly, we can also remove the !entity->rq check in drm_sched_job_init(). And for the better, given that the error message, if it ever triggered, would have dereferenced the yet un-initialized job-> sched (only initialized later in drm_sched_job_arm()). This appears to have been theoretically broken ever since commit 56e449603f0a ("drm/sched: Convert the GPU scheduler to variable number of run-queues") .
