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 From: Ni, Ray Sent: Wednesday, August 25, 2021 8:28 AM To: Dong, Guo ; devel@edk2.groups.io; kingsumos@gmail.com Cc: Liu, Zhiguang ; Tan, Dun Subject: RE: [edk2-devel] [PATCH] UefiPayloadPkg: Add FV Guid for DXEFV and PLDFV 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.

If so, this change should not impact the coreboot FV parse to find the FV entrypoint. https://github.com/coreboot/coreboot/blob/master/util/cbfstool/cbfs-mkpayload.c Thanks, Guo From: Ni, Ray > Sent: Tuesday, August 24, 2021 4:45 AM To: devel@edk2.groups.io; kingsumos@gmail.com; Dong, Guo > Cc: Liu, Zhiguang >; Tan, Dun > Subject: RE: [edk2-devel] [PATCH] UefiPayloadPkg: Add FV Guid for DXEFV and PLDFV It seems like the coreboot cannot support FV that contains GUID in its header.

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. commit 4bac086e8e007c7143e33f87bb96238326d1d6ba Author: Zhiguang Liu > Date: Wed Jul 14 14:24:45 2021 +0800 UefiPayloadPkg: Add FV Guid for DXEFV and PLDFV Signed-off-by: Zhiguang Liu > Reviewed-by: Ray Ni > Reviewed-by: Guo Dong > Kind regards, Sumo On Wed, Jul 14, 2021 at 1:08 PM Guo Dong > wrote: Signed-off-by: Guo Dong > > -----Original Message----- > From: devel@edk2.groups.io > On Behalf Of > Zhiguang Liu > Sent: Tuesday, July 13, 2021 11:25 PM > To: devel@edk2.groups.io > Subject: [edk2-devel] [PATCH] UefiPayloadPkg: Add FV Guid for DXEFV and > PLDFV > > Signed-off-by: Zhiguang Liu > > --- > UefiPayloadPkg/UefiPayloadPkg.fdf | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/UefiPayloadPkg/UefiPayloadPkg.fdf > b/UefiPayloadPkg/UefiPayloadPkg.fdf > index 2d51fdbacb..041fed842c 100644 > --- a/UefiPayloadPkg/UefiPayloadPkg.fdf > +++ b/UefiPayloadPkg/UefiPayloadPkg.fdf > @@ -34,6 +34,7 @@ FV = PLDFV > > > > ########################################################## > ###################### > > [FV.PLDFV] > > +FvNameGuid = 96E75986-6FDD-491E-9FD5-35E21AC45B45 > > BlockSize = $(FD_BLOCK_SIZE) > > FvAlignment = 16 > > ERASE_POLARITY = 1 > > @@ -62,6 +63,7 @@ FILE FV_IMAGE = 4E35FD93-9C72-4c15-8C4B- > E77F1DB2D793 { > > ########################################################## > ###################### > > > > [FV.DXEFV] > > +FvNameGuid = 8063C21A-8E58-4576-95CE-089E87975D23 > > BlockSize = $(FD_BLOCK_SIZE) > > FvForceRebase = FALSE > > FvAlignment = 16 > > -- > 2.30.0.windows.2 > > > > -=-=-=-=-=-= > Groups.io Links: You receive all messages sent to this group. > View/Reply Online (#77762): https://edk2.groups.io/g/devel/message/77762 > Mute This Topic: https://groups.io/mt/84196221/1781375 > Group Owner: devel+owner@edk2.groups.io > Unsubscribe: https://edk2.groups.io/g/devel/unsub [guo.dong@intel.com] > -=-=-=-=-=-= >
