| 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 |
