From 2cdad62b9e437ac09ccb30372c7d4486a485f545 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 24 Nov 2023 11:11:06 +0200 Subject: [PATCH] base-config: Enable DRM_FBDEV_EMULATION fro HDMI audio With the 6.7.0-rc2 update preparation with the sof-kconfig generated config we lost HDMI audio on all platforms. It turned out that the reason for it is that DRM_FBDEV_EMULATION is no longer enabled. See the following commits: bb6c4507fe82 ("drm: fix up fbdev Kconfig defaults") a5ae331edb02b ("drm: Drop select FRAMEBUFFER_CONSOLE for DRM_FBDEV_EMULATION") 701d2054fa317 ("fbdev: Make support for userspace interfaces configurable") and possibly more. The connection is not clear, but we cannot afford to loose HDMI audio.
