|
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.

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.

Say Y here if you want the RapidIO subsystem to produce a bunch of

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.
