RapidIO Subsystem Guide |

Introduction |
|
============ |
|
|
|
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. |
|
|
|
Known Bugs and Limitations |
|
========================== |
|
|
|
Bugs |
|
---- |
|
|
|
None. ;) |
|
|
|
Limitations |
|
----------- |
|
|
|
1. Access/management of RapidIO memory regions is not supported |
|
|
|
2. Multiple host enumeration is not supported |
|
|
|
RapidIO driver interface |
|
======================== |
|
|
|
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. |
|
