-RapidIO subsystem mport driver for IDT Tsi721 PCI Express-to-SRIO bridge.
-I. Overview
-This driver implements all currently defined RapidIO mport callback functions.
-It supports maintenance read and write operations, inbound and outbound RapidIO
-doorbells, inbound maintenance port-writes and RapidIO messaging.
-To generate SRIO maintenance transactions this driver uses one of Tsi721 DMA
-channels. This mechanism provides access to larger range of hop counts and
-destination IDs without need for changes in outbound window translation.
-RapidIO messaging support uses dedicated messaging channels for each mailbox.
-For inbound messages this driver uses destination ID matching to forward messages
-into the corresponding message queue. Messaging callbacks are implemented to be
-fully compatible with RIONET driver (Ethernet over RapidIO messaging services).
-II. Known problems
- None.
-III. To do
- Add DMA data transfers (non-messaging).
- Add inbound region (SRIO-to-PCIe) mapping.
-IV. Version History
- 1.0.0 - Initial driver release.
