From 2553bacaf953b48c59357f5a622282bc0c45adae Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 23 Feb 2023 17:20:48 +0200 Subject: [PATCH] drm/i915: Preserve crtc_state->inherited during state clearing MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit intel_crtc_prepare_cleared_state() is unintentionally losing the "inherited" flag. This will happen if intel_initial_commit() is forced to go through the full modeset calculations for whatever reason. Afterwards the first real commit from userspace will not get forced to the full modeset path, and thus eg. audio state may not get recomputed properly. So if the monitor was already enabled during boot audio will not work until userspace itself does an explicit full modeset.
