+What: /config/acpi
+Date: July 2016
+KernelVersion: 4.8
+Contact: linux-acpi@vger.kernel.org
+Description:
+ This represents the ACPI subsystem entry point directory. It
+ contains sub-groups corresponding to ACPI configurable options.
+
+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
