[edk2-devel] [PATCH 0/6] UefiPayloadPkg: LinuxBoot Support in UefiPayload

[Ni, Ray]

Cheng-Chieh,
Thanks for the detailed explanation in doc https://docs.google.com/document/d/1mU6ICHTh0ot8U45uuRENKOGI8cVzizdyWHGYHpEguVg/edit#heading=h.xzptrog8pyxf.

My original thought was LinuxBoot is a payload that aims to boot OS.
But the idea of chaining UefiPayload producing UEFI services is very brilliant.

Have you considered to produce the universal payload interfaces (https://universalpayload.github.io/documentation/) from LinuxBoot so no LbParseLib is required?

Thanks,
Ray
