  12 Description:
  13
  14                 This group contains the configuration for user defined ACPI
  15                 tables. The attributes of a user define table are:
  16
  17                 aml
  18                               - a binary attribute that the user can use to
  19                                 fill in the ACPI aml definitions. Once the aml
  20                                 data is written to this file and the file is
  21                                 closed the table will be loaded and ACPI devices
  22                                 will be enumerated. To check if the operation is
  23                                 successful the user must check the error code
  24                                 for close(). If the operation is successful,
  25                                 subsequent writes to this attribute will fail.
  26
  27                 The rest of the attributes are read-only and are valid only
  28                 after the table has been loaded by filling the aml entry:
