System and method for using a firmware interface table to dynamically load an ACPI SSDT

摘要

The firmware interface table (FIT) of IA-64 instruction set is used to populate the hardware component namespace using secondary system description table (SSDT) data, where the SSDT data describes components in the system. At boot-up time all hardware components are discovered. The Advanced Configuration Power Interface (ACPI) sub-system, in the system firmware, consumes the data set-up and loads the SSDTs from the FIT to create the namespace for the active system components.
