  14                 This group contains the configuration for user defined ACPI
  15                 tables. The attributes of a user define table are:
  16
  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.
  25
  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:
  28
  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
