RapidIO: add mport driver for Tsi721 bridge
Add RapidIO mport driver for IDT TSI721 PCI Express-to-SRIO bridge device. The driver provides full set of callback functions defined for mport devices in RapidIO subsystem. It also is compatible with current version of RIONET driver (Ethernet over RapidIO messaging services). This patch is applicable to kernel versions starting from 2.6.39.

|
|||
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.
