drm/amd: fix scheduler fence teardown order v2

2016-10-31T16:43:20+00:00

Some fences might be alive even after we have stopped the scheduler leading to warnings about leaked objects from the SLUB allocator. Fix this by allocating/freeing the SLUB allocator from the module init/fini functions just like we do it for hw fences. v2: make variable static, add link to bug Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=97500 Reported-by: Grazvydas Ignotas Signed-off-by: Christian König Reviewed-by: Alex Deucher (v1) Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amdgpu: fix sched fence slab teardown

2016-10-24T21:00:38+00:00

To free fences, call_rcu() is used, which calls amd_sched_fence_free() after a grace period. During teardown, there is no guarantee all callbacks have finished, so sched_fence_slab may be destroyed before all fences have been freed. If we are lucky, this results in some slab warnings, if not, we get a crash in one of rcu threads because callback is called after amdgpu has already been unloaded. Fix it with a rcu_barrier().
