Disable building video_bochs for EFI x86 platforms. For EFI platforms efi_gop or efi_uga should provide the video support. Currently, in EFI platforms there is a risk that both the bochs devices is present and the EFI video interface - which can cause unexpected video corruption when a mix of the two interfaces are used. This can happen when all_video is loaded for simplicity in a GRUB config.
There is some additional analysis from the Qemu team in this thread: https://gitlab.com/qemu-project/qemu/-/issues/2562 This is an issue on some major distros such as Debian on EFI when running under Qemu and potentially other scenarios. There is some discussion on the Debian side in this thread: https://salsa.debian.org/kernel-team/linux/-/merge_requests/1453 This relates to this discussion from grub-devel also: https://lists.gnu.org/archive/html/grub-devel/2025-09/msg00244.html Fixes: https://savannah.gnu.org/bugs/index.php?66200 Andrew Hamilton (1): build: Disable building video_bochs for EFI x86 platforms grub-core/Makefile.core.def | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) -- 2.47.3 _______________________________________________ Grub-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/grub-devel
