The UEFI standard defines various standard variables, for example OsIndicationsSupported
, in the namespace identified by GUID "{8be4df61-93ca-11d2-aa0d-00e098032b8c}"
.
I need to declare that GUID as a constant in my code, and hence I need a name for it. I guess I could just make something up, but if there is a standard name for it, it would be better to use that. So does this namespace have a standard name?
This GUID is officially called EFI_GLOBAL_VARIABLE
. See UEFI Spec Version 2.9
(March 2021), page 82 (page 157 of PDF):
#define EFI_GLOBAL_VARIABLE \
{0x8BE4DF61,0x93CA,0x11d2,\
{0xAA,0x0D,0x00,0xE0,0x98,0x03,0x2B,0x8C}}
