Description

See emulation/qemu-i440fx/25.03-154-g9e757b3396/2025-04-10T04_35_41Z in the board status repository for the configuration.

Building coreboot (25.03-154-g9e757b3396) for emulation/qemu-i440fx with GRUB (master) as payload, cbmem does not find the CBMEM tables and aborts with Table not found..

qemu-system-x86_64 -bios /dev/shm/coreboot/build/coreboot.rom -L /dev/shm -enable-kvm -smp cpus=2 -m 1G -hda /dev/shm/debian-32.img -serial stdio -net nic -net user,hostfwd=tcp::22222-:22

Using SeaBIOS, it works.

In the GRUB command line, running GRUB’s cbmemc, it outputs the CBMEM console content. So, it seems to be overwritten later somehow.
