Fields

attributes: u32

UEFI variable attributes associated with the variable: access rights (RT/BS).

Used as input for the SetVariable command. Used as output for the GetVariable command.

name_address: U64<NativeEndian>

GPA of the buffer containing a 16-bit unicode variable name.

Memory at this location is read for the GetVariable, SetVariable, GetNextVariable command. Memory at this location is written to for the GetNextVariable command.

name_bytes: u32

Size in bytes of the buffer at VariableNameAddress.

Used as input for GetVariable, SetVariable, and GetNextVariable commands. Used as output for the GetNextVariable command.

vendor_guid: Guid

A GUID comprising the other half of the variable name.

Used as input for GetVariable, SetVariable, and GetNextVariable commands. Used as output for the GetNextVariable command.

data_address: U64<NativeEndian>

GPA of the buffer containing variable data. Memory at this location is written to for the GetVariable command.

Memory at this location is read for the SetVariable command.

data_bytes: u32

Size of the buffer at VariableDataAddress.

Used as input for the GetVariable command. Used as output for the GetVariable and SetVariable commands.
