From 7671f62c10f2a4c77d89b39fd50fab7f918d6809 Mon Sep 17 00:00:00 2001 From: Josip Pavic Date: Tue, 24 Sep 2024 17:25:54 -0400 Subject: [PATCH 01/16] drm/amd/display: Clear update flags after update has been applied [Why] Since the surface/stream update flags aren't cleared after applying updates, those same updates may be applied again in a future call to update surfaces/streams for surfaces/streams that aren't actually part of that update (i.e. applying an update for one surface/stream can trigger unintended programming on a different surface/stream). For example, when an update results in a call to program_front_end_for_ctx, that function may call program_pipe on all pipes. If there are surface update flags that were never cleared on the surface some pipe is attached to, then the same update will be programmed again. [How] Clear the surface and stream update flags after applying the updates.

First time driver is removed, memory is freed but when second time the driver is inserted, VBIOS dmub is not active, since the PSP policy is to retain the driver loaded version on subsequent warm boots. Hence, communication with VBIOS DMUB fails. Fix this by aborting further communication with vbios dmub and release the memory immediately.
