| 15 | bool "Enable RapidIO Input/Output Ports" | |
| 16 | depends on RAPIDIO | |
| 17 | ---help--- | |
| 18 | The RapidIO specification describes a Output port transmit | |
| 19 | enable and a Input port receive enable. The recommended state | |
| 20 | for Input ports and Output ports should be disabled. When | |
| 21 | this switch is set the RapidIO subsystem will enable all | |
| 22 | ports for Input/Output direction to allow other traffic | |
| 23 | than Maintenance transfers. | |

| 29 | select DMA_ENGINE | |
| 30 | help | |
| 31 | Say Y here if you want to use DMA Engine frameork for RapidIO data | |
| 32 | transfers to/from target RIO devices. RapidIO uses NREAD and | |
| 33 | NWRITE (NWRITE_R, SWRITE) requests to transfer data between local | |
| 34 | memory and memory on remote target device. You need a DMA controller | |
| 35 | capable to perform data transfers to/from RapidIO. | |
| 36 | ||
| 37 | If you are unsure about this, say Y here. | |

| 43 | Say Y here if you want the RapidIO subsystem to produce a bunch of | |
| 44 | debug messages to the system log. Select this if you are having a | |
| 45 | problem with the RapidIO subsystem and want to see more of what is | |
| 46 | going on. | |

| 53 | default RAPIDIO_ENUM_BASIC | |
| 54 | help | |
| 55 | There are different enumeration and discovery mechanisms offered | |
| 56 | for RapidIO subsystem. You may select single built-in method or | |
| 57 | or any number of methods to be built as modules. | |
| 58 | Selecting a built-in method disables use of loadable methods. | |
| 59 | ||
| 60 | If unsure, select Basic built-in. | |
