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:
17 aml - a binary attribute that the user can use to
18 fill in the ACPI aml definitions. Once the aml
19 data is written to this file and the file is
20 closed the table will be loaded and ACPI devices
21 will be enumerated. To check if the operation is
22 successful the user must check the error code
23 for close(). If the operation is successful,
24 subsequent writes to this attribute will fail.
26 The rest of the attributes are read-only and are valid only
27 after the table has been loaded by filling the aml entry:
29 signature - ASCII table signature
30 length - length of table in bytes, including the header
31 revision - ACPI Specification minor version number
32 oem_id - ASCII OEM identification
33 oem_table_id - ASCII OEM table identification
34 oem_revision - OEM revision number
35 asl_compiler_id - ASCII ASL compiler vendor ID
36 asl_compiler_revision - ASL compiler version
