It 7*4882a593Smuzhiyun contains sub-groups corresponding to ACPI configurable options. 8*4882a593Smuzhiyun 9*4882a593SmuzhiyunWhat: /config/acpi/table 10*4882a593SmuzhiyunDate: July 2016 11*4882a593SmuzhiyunKernelVersion: 4.8 12*4882a593SmuzhiyunDescription: 13*4882a593Smuzhiyun 14*4882a593Smuzhiyun This group contains the configuration for user defined ACPI 15*4882a593Smuzhiyun tables. The attributes of a user define table are: 16*4882a593Smuzhiyun 17*4882a593Smuzhiyun aml 18*4882a593Smuzhiyun - a binary attribute that the user can use to 19*4882a593Smuzhiyun fill in the ACPI aml definitions. Once the aml 20*4882a593Smuzhiyun data is written to this file and the file is 21*4882a593Smuzhiyun closed the table will be loaded and ACPI devices 22*4882a593Smuzhiyun will be enumerated. To check if the operation is 23*4882a593Smuzhiyun successful the user must check the error code 24*4882a593Smuzhiyun for close(). If the operation is successful, 25*4882a593Smuzhiyun subsequent writes to this attribute will fail. 26*4882a593Smuzhiyun 27*4882a593Smuzhiyun The rest of the attributes are read-only and are valid only 28*4882a593Smuzhiyun after the table has been loaded by filling the aml entry: 29*4882a593Smuzhiyun 30*4882a593Smuzhiyun signature 31*4882a593Smuzhiyun - ASCII table signature 32*4882a593Smuzhiyun 33*4882a593Smuzhiyun length 34*4882a593Smuzhiyun - length of table in bytes, including the header 35*4882a593Smuzhiyun 36*4882a593Smuzhiyun revision 37*4882a593Smuzhiyun - ACPI Specification minor version number 38*4882a593Smuzhiyun 39*4882a593Smuzhiyun oem_id 40*4882a593Smuzhiyun - ASCII OEM identification 41*4882a593Smuzhiyun 42*4882a593Smuzhiyun oem_table_id 43*4882a593Smuzhiyun - ASCII OEM table identification 44*4882a593Smuzhiyun 45*4882a593Smuzhiyun oem_revision 46*4882a593Smuzhiyun - OEM revision number 47*4882a593Smuzhiyun 48*4882a593Smuzhiyun asl_compiler_id 49*4882a593Smuzhiyun - ASCII ASL compiler vendor ID 50*4882a593Smuzhiyun 51*4882a593Smuzhiyun asl_compiler_revision 52*4882a593Smuzhiyun - ASL compiler version 53
