The EFI subsystem updates have been merged for the in-development Linux 7.0 kernel. Worth mentioning here is a new quirk for helping Valve’s Steam Deck handheld.
Tvrtko Ursulin of Igalia landed a fix to the EFI system frame-buffer code for fixing the EFIDRMFB and SimpleDRMFB frame-buffer drivers on Valve’s Steam Deck. This quirk/fix is ultimately to allow using the frame-buffer drivers in the correct orientation and ensuring a fake mode isn’t used that could lead to corrupted rendering.


So it seems there’s already a fix for it lmao
