Re: [libvirt] [RFC] Defining firmware (OVMF, et al) metadata format & file

> - Support architectures - associated QEMU feature flags (Secure > Boot) Also machine types. ovmf builds with smm don't boot on pc. coreboot has hardware-specific roms too, so the pc build wouldn't boot on q35 and visa versa. Same on arm, where the firmware typically is board-specific. > - If the binary provides / requires SMM (System Management Mode) Possibly a more generic "flags" or "properties" thing, I can easily imagine that simliar requirements show up on other platforms too. Also a "name" and a "description" field would be useful. cheers, Gerd
