Issue #590 has been updated by Paul Menzel. File 0001-kern-coreboot-mmap-Map-to-reserved.patch added Subject changed from emulation/qemu-i440fx with GRUB payload: cbmem fails with `Table not found.` to With GRUB payload cbmem in GNU/Linux fails with `Table not found.`
Indeed, adding `iomem=relaxed` to the Linux kernel command line, `cbmem -c` works. Untested(?) GRUB patch attached. ---------------------------------------- Bug #590: With GRUB payload cbmem in GNU/Linux fails with `Table not found.` https://ticket.coreboot.org/issues/590#change-2065 * Author: Paul Menzel * Status: New * Priority: Normal * Target version: none * Start date: 2025-04-10 * Affected versions: 25.03 * Related links: In the GRUB command line, running GRUB’s `cbmemc`, it outputs the CBMEM console content. So, it seems to be overwritten later somehow. ---------------------------------------- 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. ---Files-------------------------------- 0001-kern-coreboot-mmap-Map-to-reserved.patch (1.35 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.
