| 10 | ---help--- |
| 11 | Amount of time a discovery node waits for a host to complete |
| 12 | enumeration before giving up. |

| 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. |

| 42 | help |
| 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. |

| 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. |

| 63 | tristate "Basic" |
| 64 | help |
| 65 | This option includes basic RapidIO fabric enumeration and discovery |
| 66 | mechanism similar to one described in RapidIO specification Annex 1. |
