30 | The RapidIO specification describes a Output port transmit |
31 | enable and a Input port receive enable. The recommended state | |
32 | for Input ports and Output ports should be disabled. When | |
33 | this switch is set the RapidIO subsystem will enable all | |
34 | ports for Input/Output direction to allow other traffic | |
35 | than Maintenance transfers. | |

42 | help | |
43 | Say Y here if you want to use DMA Engine frameork for RapidIO data | |
44 | transfers to/from target RIO devices. RapidIO uses NREAD and | |
45 | NWRITE (NWRITE_R, SWRITE) requests to transfer data between local | |
46 | memory and memory on remote target device. You need a DMA controller | |
47 | capable to perform data transfers to/from RapidIO. | |
