59 58 * Naming convention for AML interpreter execution routines.
60 59 *
61 60 * The routines that begin execution of AML opcodes are named with a common
62 61 * convention based upon the number of arguments, the number of target operands,
63 62 * and whether or not a value is returned:
64 63 *
65 64 * AcpiExOpcode_xA_yT_zR
66 65 *
67 66 * Where:
68 67 *
69 68 * xA - ARGUMENTS: The number of arguments (input operands) that are
70 69 * required for this opcode type (1 through 6 args).
71 70 * yT - TARGETS: The number of targets (output operands) that are required
72 71 * for this opcode type (0, 1, or 2 targets).
73 72 * zR - RETURN VALUE: Indicates whether this opcode type returns a value
74 73 * as the function return (0 or 1).
75 74 *
76 75 * The AcpiExOpcode* functions are called via the Dispatcher component with
77 76 * fully resolved operands.
