Hi Jaben,

 =

I think the= “Payload Image Extend Header”= ; means the optional tables below in Payload Image Format.

These tables exist only when corresponding = bit is set in Capability field.

  • Payload Image Relocati= on Table
  • Payload Image Authenti= cation Table

 =

Thanks,

Guo

Is there any more information on “Payload Image Extend Header”? This is mention= ed, but I don’t see detailed information.

Subject: [edk2-devel] RFC: Universal Payload Interface

 

With the fact that there are many different firmwar= e implementations, we tried to decouple today’s monolithic UEFI firmw= are binary to two independent components: bootloader and payload.

 

Basically, bootloader initializes the silicon hardw= are and payload prepares the OS required data and services. Bootloader pass= es control to payload.

 

https://universalpayload.github.io/documentation/s= pec/spec.html defines the universal interface between bootloader and pa= yload. So that different bootloaders can work with different payloads, initializing different hardware and boo= ting different OSes.

The interface document is in very draft phase. Any = feedback is welcome.

 

We also developed the POC code to demonstrate the i= dea. Please use below steps to get the code that uses SBL as the bootloader= and EDKII UEFI Payload as the payload. This POC is being developed for QEM= U Q35 virtual machine.

  1. Run “git clone https://github.c= om/universalpayload/tools.git payload”

This step downloads the initial tools that w= ill setup the dev environment.

  1. Run “py -3 clone_and_build_sbl_with_uefipayload.py” in t= he “payload” directory

This script downloads branched SBL (https://github= .com/universalpayload/slimbootloader.git) and edk2 (https://github.com/universalpayload/e= dk2.git).

Then it builds the firmware binary “Sl= imBootloader.bin” in “codeworkspace” directory.

  1. Boot QEMU by running “qemu-system-x86_64.exe -machine q35 -pfl= ash  codeworkspace\SlimBootloader.bin  -serial file:test.log̶= 1;

 

Because the code is under active development, pleas= e contact us when you cannot build or boot successfully.

 

Besides the SBL, we modified coreboot (https://github.com/univers= alpayload/coreboot.git) to let it conform to the universal interface as= a bootloader.

Besides the EDK2 UEFI Payload, we created a payload= (https://= github.com/universalpayload/linuxpayload.git) that can boot Linux.=

 

Thanks,

Ray
