Subject: Re: [PATCH v3 0/2] efi/x86: Call set_os() protocol on dual GPU Macs

https://www.phoronix.com/forums/forum/software/general-linux-open-source/1479158-linux-6-11-efi-will-fake-that-it-s-booting-apple-macos-to-fix-some-dual-gpu-macs?p=1479205#post1479205

By looking at this post, it seems to affect non T2 Macs as well.

Also, T2 Macs report that EFI v2 is being used, although by a kernel patch, we force them to use v1.  Have we can use this as a quirk for enabling apple-set-os?

Although, the NVRAM variable idea by Ard looks better to me.
