Hi, This commit breaks suspend/resume on my Carrizo A12-9800 system.
[root@carrizo linux2]# git bisect bad 7ae4acd21e9e264afb079e23d43bcf2238c7dbea is the first bad commit commit 7ae4acd21e9e264afb079e23d43bcf2238c7dbea Author: Leo (Sunpeng) Li <sunpeng...@amd.com> Date: Thu Sep 7 17:05:38 2017 -0400 drm/amd/display: Match actual state during S3 resume. During system suspend, we: 1. Cache a duplicate of the current DRM atomic state, which calls hooks to duplicate our internal states. 2. Call hooks to disable all functionalities. 3. System suspended. During resume, we attempt to restore the cached state. However, our interal states are now stale, since step 1 was done before step 2. i.e. our cached state does not reflect the disabled nature of things. This change resolves that by destroying all relevant states to reflect the actual state during resume.
