  10. KernelVersion: 4.8
  11. Description:
  12. This group contains the configuration for user defined ACPI
  13. tables. The attributes of a user define table are:
  14. aml
  15. - a binary attribute that the user can use to
  16. fill in the ACPI aml definitions. Once the aml
  17. data is written to this file and the file is
  18. closed the table will be loaded and ACPI devices
  19. will be enumerated. To check if the operation is
  20. successful the user must check the error code
  21. for close(). If the operation is successful,
  22. subsequent writes to this attribute will fail.
  23. The rest of the attributes are read-only and are valid only
  24. after the table has been loaded by filling the aml entry:
  25. signature
  26. - ASCII table signature
  27. length
  28. - length of table in bytes, including the header
  29. revision
  30. - ACPI Specification minor version number
  31. oem_id
  32. - ASCII OEM identification
  33. oem_table_id
  34. - ASCII OEM table identification
  35. oem_revision
  36. - OEM revision number
  37. asl_compiler_id
  38. - ASCII ASL compiler vendor ID
  39. asl_compiler_revision
