Hi, Bret
For UefiPayloadPkg, could you please provide a patch for it ?
Thanks

UefiPayloadPkg maintainers: what say you? 😉

(1) This wiki article is helpful, thanks.
I have one remark: there's a heading saying "VarCheckPolicyLib NULL
Instance":
https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Ftianocore%2Ftianocore.github.io%2Fwiki%2FVariablePolicy-Protocol---Enhanced-Method-for-Managing-Variables%23varcheckpolicylib-null-instance&data=02%7C01%7Cbret.barkelew%40microsoft.com%7C98d423482cea4e143c4308d7f66b0927%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637248811886928541&sdata=4qTYEB6%2F3uJnLZ9MjRHODQGaaPq6zZEp7bFlCXEP7gI%3D&reserved=0
I think what's meant is "NULL class", not "NULL instance".
(2) The following platform DSC files in edk2 include the non-SMM
variable driver
("MdeModulePkg/Universal/Variable/RuntimeDxe/VariableRuntimeDxe.inf"),
but they are not modified by this patch series:
ArmVirtPkg/ArmVirtQemu.dsc
ArmVirtPkg/ArmVirtQemuKernel.dsc
ArmVirtPkg/ArmVirtXen.dsc
OvmfPkg/OvmfXen.dsc
UefiPayloadPkg/UefiPayloadPkgIa32.dsc
UefiPayloadPkg/UefiPayloadPkgIa32X64.dsc
I'm asking that you please (a) include a patch for ArmVirtPkg, (b)
update the OvmfPkg patch to cover "OvmfXen.dsc" too.
Not sure about the UefiPayloadPkg platforms; please ask their maintainers.
(I've CC'd the OvmfXen and UefiPayloadPkg maintainers/reviewers.)
Thanks,
Laszlo
