drm/amdgpu/dce: Don't turn off DP sink when disconnected

2018-03-22T08:23:31+00:00

commit 7d617264eb22b18d979eac6e85877a141253034e upstream. Turning off the sink in this case causes various issues, because userspace expects it to stay on until it turns it off explicitly. Instead, turn the sink off and back on when a display is connected again. This dance seems necessary for link training to work correctly.

drm/amdkfd: Fix memory leaks in kfd topology

2018-03-22T08:23:29+00:00

[ Upstream commit 5108d768408abc80e4e8d99f5b406a73cb04056b ] Kobject created using kobject_create_and_add() can be freed using kobject_put() when there is no referenece any more. However, kobject memory allocated with kzalloc() has to set up a release callback in order to free it when the counter decreases to 0. Otherwise it causes memory leak.

E.g., some 1 RB chips are actually 1 RB chips, others are actually harvested 2 RB chips.

drm/amdgpu: Fix deadlock on runtime suspend

2018-03-18T10:17:48+00:00

commit aa0aad57909eb321746325951d66af88a83bc956 upstream. amdgpu's ->runtime_suspend hook calls drm_kms_helper_poll_disable(), which waits for the output poll worker to finish if it's running. The output poll worker meanwhile calls pm_runtime_get_sync() in amdgpu's ->detect hooks, which waits for the ongoing suspend to finish, causing a deadlock. Fix by not acquiring a runtime PM ref if the ->detect hooks are called in the output poll worker's context. This is safe because the poll worker is only enabled while runtime active and we know that ->runtime_suspend waits for it to finish.

commit 458d876eb869d5a88b53074c6c271b8b9adc0f07 upstream. We only support vga_switcheroo and runtime pm on PX/HG systems so forcing runpm to 1 doesn't do anything useful anyway. Only call vga_switcheroo_init_domain_pm_ops() for PX/HG so that the cleanup path is correct as well.
