1RapidIO subsystem mport driver for IDT Tsi721 PCI Express-to-SRIO bridge. 2========================================================================= 3 4I. Overview 5 6This driver implements all currently defined RapidIO mport callback functions. 7It supports maintenance read and write operations, inbound and outbound RapidIO 8doorbells, inbound maintenance port-writes and RapidIO messaging. 9 10To generate SRIO maintenance transactions this driver uses one of Tsi721 DMA 11channels. This mechanism provides access to larger range of hop counts and 12destination IDs without need for changes in outbound window translation. 13 14RapidIO messaging support uses dedicated messaging channels for each mailbox. 15For inbound messages this driver uses destination ID matching to forward messages 16into the corresponding message queue. Messaging callbacks are implemented to be 17fully compatible with RIONET driver (Ethernet over RapidIO messaging services). 18 19II. Known problems 20 21 None. 22 23III. To do 24 25 Add DMA data transfers (non-messaging). 26 Add inbound region (SRIO-to-PCIe) mapping. 27 28IV. Version History 29 30 1.0.0 - Initial driver release. 31 32V.
