| 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 |
