2 | Definition of the global NVS area protocol. This protocol\r | |
3 | publishes the address and format of a global ACPI NVS buffer\r | |
4 | used as a communications buffer between SMM code and ASL code.\r | |
5 | The format is derived from the ACPI reference code, version 0.95.\r | |
6 | Note: Data structures defined in this protocol are not naturally aligned.\r | |
