drm/amdgpu: stop using the ring index in the SA

2016-03-14T17:43:27Z

The ring index will always collide as hash into the fence list, so use the context number instead. That can still cause collisions, but they are less likely than using ring indices. Signed-off-by: Christian König Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: use WARN_ON_ONCE instead of BUG_ON in the SA

2016-02-10T19:17:03Z

Crashing the system doesn't helps at all. Also properly return -EINVAL if size or alignment are outside valid ranges. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: hold reference to fences in amdgpu_sa_bo_new (v2)

2016-02-10T19:07:31Z

An arbitrary amount of time can pass between spin_unlock and fence_wait_any_timeout, so we need to ensure that nobody frees the fences from under us. A stress test (rapidly starting and killing hundreds of glxgears instances) ran into a deadlock in fence_wait_any_timeout after about an hour, and this race condition appears to be a plausible cause. v2: agd: rebase on upstream Signed-off-by: Nicolai Hähnle Reviewed-by: Alex Deucher Reviewed-by: Christian König Cc: stable@vger.kernel.org
