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
