For more information on EFI variables, + see 'Variable Services' in the UEFI specification + (section 7.2 in specification version 2.3 Errata D). + + In summary, EFI variables are named, and are classified + into separate namespaces through the use of a vendor + GUID. They also have an arbitrary binary value + associated with them. + + The efivars module enumerates these variables and + creates a separate directory for each one found. Each + directory has a name of the form "<key>-<vendor guid>" + and contains the following files: + + attributes: A read-only text file enumerating the + EFI variable flags. Potential values + include: + + EFI_VARIABLE_NON_VOLATILE + EFI_VARIABLE_BOOTSERVICE_ACCESS + EFI_VARIABLE_RUNTIME_ACCESS + EFI_VARIABLE_HARDWARE_ERROR_RECORD + EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS + + See the EFI documentation for an + explanation of each of these variables. + + data: A read-only binary file that can be read + to attain the value of the EFI variable + + guid: The vendor GUID of the variable.
