https://bugzilla.kernel.org/show_bug.cgi?id=93281 --- Comment #14 from Alex Deucher <alexdeucher@xxxxxxxxx> --- Macs apparently only make the vbios image available during the pre-OS EFI environment. Once the OS loads, the image is no longer available so the boot loader needs to grab it and stash it somewhere so that the OS can access it once it as taken over. https://bugs.freedesktop.org/show_bug.cgi?id=26891 "As stated above, you cannot use grub to load the firmware as the information is only accessible before you exit the boot services in EFI. The kernel must be booted using EFI stub booting (that's where the code for getting the bios image is). I use rEFInd as this now automaigcally passes the initramfs location to the kernel." Someone would probably need to port the relevant code from rEFInd for grub. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
