Alexandre Bounine48618fb2011-11-02 13:39:09 -07001RapidIO 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.
