The recommended state for Input ports and Output ports should be disabled. When this switch is set the RapidIO subsystem will enable all ports for Input/Output direction to allow other traffic than Maintenance transfers. config RAPIDIO_DMA_ENGINE bool "DMA Engine support for RapidIO" depends on RAPIDIO depends on DMADEVICES select DMA_ENGINE help Say Y here if you want to use DMA Engine frameork for RapidIO data transfers to/from target RIO devices. RapidIO uses NREAD and NWRITE (NWRITE_R, SWRITE) requests to transfer data between local memory and memory on remote target device. You need a DMA controller capable to perform data transfers to/from RapidIO. If you are unsure about this, say Y here. config RAPIDIO_DEBUG bool "RapidIO subsystem debug messages" depends on RAPIDIO help Say Y here if you want the RapidIO subsystem to produce a bunch of debug messages to the system log. Select this if you are having a problem with the RapidIO subsystem and want to see more of what is going on. If you are unsure about this, say N here. choice prompt "Enumeration method" depends on RAPIDIO default RAPIDIO_ENUM_BASIC help There are different enumeration and discovery mechanisms offered for RapidIO subsystem. You may select single built-in method or or any number of methods to be built as modules. Selecting a built-in method disables use of loadable methods. If unsure, select Basic built-in. config RAPIDIO_ENUM_BASIC tristate "Basic" help This option includes basic RapidIO fabric enumeration and discovery mechanism similar to one described in RapidIO specification Annex 1. endchoice config RAPIDIO_CHMAN tristate "RapidIO Channelized Messaging driver" depends on RAPIDIO help This option includes RapidIO channelized messaging driver which provides socket-like interface to allow sharing of single RapidIO messaging mailbox between multiple user-space applications. See "Documentation/driver-api/rapidio/rio_cm.rst" for driver description. config RAPIDIO_MPORT_CDEV tristate "RapidIO /dev mport device driver" depends on RAPIDIO help This option includes generic RapidIO mport device driver which allows to user space applications to perform RapidIO-specific operations through selected RapidIO mport. menu "RapidIO Switch drivers" depends on RAPIDIO source "drivers/rapidio/switches/Kconfig" endmenu |
