drm/nouveau/disp: fix use-after-free in error handling of nouveau_connector_create 2023-08-23T15:52:42+00:00 Karol Herbst kherbst@redhat.com 2023-08-14T14:49:32+00:00 3f27451c9f29d5ed00232968680c7838a44dcac7 commit 1b254b791d7b7dea6e8adc887fbbd51746d8bb27 upstream. We can't simply free the connector after calling drm_connector_init on it. We need to clean up the drm side first. It might not fix all regressions from commit 2b5d1c29f6c4 ("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts"), but at least it fixes a memory corruption in error handling related to that commit.

DCN 3.1.4 is reported to hang on s2idle entry if graphics activity is happening during entry. This is because GFXOFF was scheduled as delayed but RLC gets disabled in s2idle entry sequence which will hang GFX IP if not already in GFXOFF. To help this problem, flush any delayed work for GFXOFF early in s2idle entry sequence to ensure that it's off when RLC is changed. commit 4b31b92b143f ("drm/amdgpu: complete gfxoff allow signal during suspend without delay") modified power gating flow so that if called in s0ix that it ensured that GFXOFF wasn't put in work queue but instead processed immediately.
