RapidIO is a high speed switched fabric interconnect with
|
|
features aimed at the embedded market. RapidIO provides
|
|
support for memory-mapped I/O as well as message-based
|
|
transactions over the switched fabric network. RapidIO has
|
|
a standardized discovery mechanism not unlike the PCI bus
|
|
standard that allows simple detection of devices in a
|
|
network.

This documentation is provided for developers intending
|
|
to support RapidIO on new architectures, write new drivers,
|

or to understand the subsystem internals.

Drivers are provided a set of calls in order
|
|
to interface with the subsystem to gather info
|
|
on devices, request/map memory region resources,
|
|
and manage mailboxes/doorbells.
