Linux 7.0 Brings An EFI Framebuffer Quirk For Valve’s Steam Deck<\/a><\/p>\n

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.<\/p>\n

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.
\n<\/p>\n

\"Steam<\/p>\n

Ursulin explained with the now-merged patch:
\n
“Valve Steam Deck has a 800×1280 portrait screen installed in a landscape orientation. The firmware offers a software-rotated 1280×800 mode, which GRUB can be made to switch to when displaying a boot menu. If this mode was selected frame buffer drivers will see this fake mode and fbcon rendering will be corrupted.<\/p>\n

Let us therefore add a selective quirk inside the current “swap with and height” handling, which will detect this exact mode and fix it up back to the native one.\n<\/p>\n

This will allow the DRM-based framebuffer drivers to detect the correct mode, apply the existing panel orientation quirk, and render the console in landscape mode with no corruption.”<\/p>\n

That is the main change worth pointing out in the otherwise straight-forward EFI merge of changes for Linux 7.0.
