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