# RapidIO configuration

source "drivers/rapidio/devices/Kconfig"
config RAPIDIO_DISC_TIMEOUT
int "Discovery timeout duration (seconds)"
depends on RAPIDIO
default "30"
---help---
Amount of time a discovery node waits for a host to complete
enumeration before giving up.
config RAPIDIO_ENABLE_RX_TX_PORTS
bool "Enable RapidIO Input/Output Ports"
depends on RAPIDIO
---help---
The RapidIO specification describes a Output port transmit
enable and a Input port receive enable. 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
select 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.
