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. 24 25config RAPIDIO_DMA_ENGINE 26 bool "DMA Engine support for RapidIO" 27 depends on RAPIDIO 28 select DMADEVICES 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. 38 39config RAPIDIO_DEBUG 40 bool "RapidIO subsystem debug messages" 41 depends on RAPIDIO 42 help 43 Say Y here if you want the RapidIO subsystem to produce a bunch of 44 debug messages to the system log.

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. 61 62config RAPIDIO_ENUM_BASIC 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. 67 68endchoice 69 70menu "RapidIO Switch drivers" 71 depends on RAPIDIO 72 73source "drivers/rapidio/switches/Kconfig" 74 75endmenu 76
