drm/amd/display: enable_hpo_dp_link_output: Check link_res->hpo_dp_link_enc before using it

2024-10-10T10:01:14Z

commit d925c04d974c657d10471c0c2dba3bc9c7d994ee upstream. [WHAT & HOW] Functions dp_enable_link_phy and dp_disable_link_phy can pass link_res without initializing hpo_dp_link_enc and it is necessary to check for null before dereferencing. This fixes 1 FORWARD_NULL issue reported by Coverity.

drm/sched: revert "Always increment correct scheduler score"

2024-10-10T10:01:13Z

commit abf201f6ce14c4ceeccde5471bdf59614b83a3d8 upstream. This reverts commit 087913e0ba2b3b9d7ccbafb2acf5dab9e35ae1d5. It turned out that the original code was correct since the rq can only change when there is no armed job for an entity. This change here broke the logic since we only incremented the counter for the first job, so revert it.

drm/xe: fix UAF around queue destruction

2024-10-10T10:01:10Z

[ Upstream commit 2d2be279f1ca9e7288282d4214f16eea8a727cdb ] We currently do stuff like queuing the final destruction step on a random system wq, which will outlive the driver instance. With bad timing we can teardown the driver with one or more work workqueue still being alive leading to various UAF splats. Add a fini step to ensure user queues are properly torn down. At this point GuC should already be nuked so queue itself should no longer be referenced from hw pov. v2 (Matt B) - Looks much safer to use a waitqueue and then just wait for the xa_array to become empty before triggering the drain.

drm/amd/display: Fix system hang while resume with TBT monitor

2024-10-10T10:01:08Z

commit 52d4e3fb3d340447dcdac0e14ff21a764f326907 upstream. [Why] Connected with a Thunderbolt monitor and do the suspend and the system may hang while resume. The TBT monitor HPD will be triggered during the resume procedure and call the drm_client_modeset_probe() while struct drm_connector connector->dev->master is NULL. It will mess up the pipe topology after resume. [How] Skip the TBT monitor HPD during the resume procedure because we currently will probe the connectors after resume by default.
