Hi all,

I have push the commit to fix this issue to coreboot.org. Here is the link.

https://review.coreboot.org/c/coreboot/+/57296

This issue is caused because the coreboot implementation doesn’t handle the existence of EFI_FIRMWARE_VOLUME_EXT_HEADER, resulting in address of UefiPayloadEntry to be found incorrectly when parsing Fv.

Can you please help to review and merge this commit?

Thanks,

Dun

Dun will investigate this issue. There might be some issue in coreboot implementation that doesn’t handle the existence of EFI_FIRMWARE_VOLUME_EXT_HEADER.

Hi Zhiguang,

This patch just uses an actual FV GUID to replace the dummy FV GUID (all zero FV GUID) and no FV layout change, right?

If so, this change should not impact the coreboot FV parse to find the FV entrypoint.

Thanks,

Guo

It seems like the coreboot cannot support FV that contains GUID in its header.

Hi All,

This patch broke the coreboot payload loading. Tested with:

build -a IA32 -a X64 -p UefiPayloadPkg/UefiPayloadPkg.dsc -b RELEASE -t GCC5 -D BOOTLOADER=COREBOOT

Basically the coreboot cbfstool reports the following error when creating the CBFS / flash image:

"Not a usable UEFI firmware volume"

Trying to boot coreboot results in an exception and the following error message:

"Payload not loaded"

Probably it broke the interface.
