| * and whether or not a value is returned: |
| * |
| * AcpiExOpcode_xA_yT_zR |
| * |
| * Where: |
| * |
| * xA - ARGUMENTS: The number of arguments (input operands) that are |
| * required for this opcode type (1 through 6 args). |
| * yT - TARGETS: The number of targets (output operands) that are required |
| * for this opcode type (0, 1, or 2 targets). |
| * zR - RETURN VALUE: Indicates whether this opcode type returns a value |
| * as the function return (0 or 1). |
| * |
| * The AcpiExOpcode* functions are called via the Dispatcher component with |
