RE: [RISC-V][tech-server-platform] [RFC 0/2] Add RISC-V Server Platform Reference Board

[Chai, Evan]

Yes. In short term, Smbios/ACPI still need to be handled by Qemu. 
We will have a reference board to upstream to edk2-platform compatible with 
server platform spec, which is still under review now. After that, Smbios/Acpi 
will be taken over by firmware directly. 

BR,
Evan

The need for having a platform separate to virt for compliance testing was 
discussed in RISE in RVI meetings. Thanks for driving this.

Will the EDK II platform also generate the SMBIOS table or shall this be 
handled in QEMU?

Will further work in edk2-platforms be needed to provide full compliance with 
the the server platform specification?

Best regards
