[RFC PATCH v2 16/44] hw/i386: Add definitions from UEFI spec for volumes, resources, etc...

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Isaku Yamahata <isaku.yamahata@xxxxxxxxx>

Add definitions for literals, enums, structs, GUIDs, etc... that will be
used by TDX to build the UEFI Hand-Off Block (HOB) that is passed to the
Trusted Domain Virtual Firmware (TDVF).  All values come from the UEFI
specification and TDVF design guide. [1]

Note: EFI_RESOURCE_ATTRIBUTE_{ENCRYPTED, UNACCEPTED}, will be added
in future UEFI spec.
