When this file was split in 5d945cbcd4b16a29d6470a80dfb19738f9a4319f Author: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx> Date: Wed Jul 20 15:31:42 2022 -0400 drm/amd/display: Create a file dedicated to planes This chunk seemed to get dropped. Linus noticed on this rx580 and I've reproduced on FIJI which makes sense as these are pre-modifier GPUs. With this applied, I get gdm back.
