What:        /config/acpi/table
Date:        July 2016
KernelVersion:    4.8
Description:

        This group contains the configuration for user defined ACPI
        tables. The attributes of a user define table are:

        aml
                  - a binary attribute that the user can use to
                fill in the ACPI aml definitions. Once the aml
                data is written to this file and the file is
                closed the table will be loaded and ACPI devices
                will be enumerated. To check if the operation is
                successful the user must check the error code
                for close(). If the operation is successful,
                subsequent writes to this attribute will fail.

        The rest of the attributes are read-only and are valid only
        after the table has been loaded by filling the aml entry:

        signature
                - ASCII table signature

        length
                - length of table in bytes, including the header

        revision
                - ACPI Specification minor version number

        oem_id
                - ASCII OEM identification

        oem_table_id
                - ASCII OEM table identification

        oem_revision
                - OEM revision number

        asl_compiler_id
                - ASCII ASL compiler vendor ID

        asl_compiler_revision
                - ASL compiler version
