6 This represents the ACPI subsystem entry point directory. It
7 contains sub-groups corresponding to ACPI configurable options.
9 What: /config/acpi/table
14 This group contains the configuration for user defined ACPI
15 tables. The attributes of a user define table are:
18 - a binary attribute that the user can use to
19 fill in the ACPI aml definitions. Once the aml
20 data is written to this file and the file is
21 closed the table will be loaded and ACPI devices
22 will be enumerated. To check if the operation is
23 successful the user must check the error code
24 for close(). If the operation is successful,
25 subsequent writes to this attribute will fail.
27 The rest of the attributes are read-only and are valid only
28 after the table has been loaded by filling the aml entry:
31 - ASCII table signature
34 - length of table in bytes, including the header
37 - ACPI Specification minor version number
40 - ASCII OEM identification
43 - ASCII OEM table identification
49 - ASCII ASL compiler vendor ID
52 - ASL compiler version
