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