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.
