rapidio: add handling of redundant routes

2010-10-28T01:03:16+00:00

Detects RIO link to the already enumerated device and properly sets links
between device objects.  Changes to the enumeration/discovery logic:

1. Use Master Enable bit to signal end of the enumeration - agents may
   start their discovery process as soon as they see this bit set
   (Component Tag register was used before for this purpose).

2. Enumerator sets Component Tag (!= 0) immediately during device
   setup.  This allows to identify the device if the redundant route
   exists in a RIO system.

rapidio: add device access check into the enumeration

2010-10-28T01:03:16+00:00

Add explicit device access check before performing device enumeration.
This gives a chance to clear possible link error conditions by issuing
safe maintenance read request(s).

rapidio: add handling of orphan port-write message

2010-10-28T01:03:15+00:00

Add check for access to port-write (PW) message source device before
processing the PW message.  If source RIO device is not available (power
down or RIO link failure) trace back to a last available switch/port on
the PW message route and service failure at that point.

rapidio: modify initialization of switch operations

2010-05-27T16:12:51+00:00

Modify the way how RapidIO switch operations are declared.  Multiple
assignments through the linker script replaced by single initialization
call.

rapidio: add IDT CPS/TSI switches

2010-05-27T16:12:50+00:00

Extentions to RapidIO switch support:

1. modify switch route operation declarations to allow using single
   switch-specific file for family of switches that share the same route
   table operations.

2. add standard route table operations for switches that that support
   route table manipulation registers as defined in the Rev.1.3 of RapidIO
   specification.

3. add clear-route-table operation for switches

4. add CPSxx and TSIxxx families of RapidIO switches

[RAPIDIO] Auto-probe the RapidIO system size

2008-04-29T09:40:28+00:00

The RapidIO system size will auto probe in RIO setup.  The route table
and rionet_active in rionet.c are changed to be allocated dynamically
according to the size of the system.

[PATCH] RapidIO support: core base

2005-11-07T15:53:46+00:00

Adds a RapidIO subsystem to the kernel.  RIO is a switched fabric interconnect
used in higher-end embedded applications.  The curious can look at the specs
over at http://www.rapidio.org

The core code implements enumeration/discovery, management of
devices/resources, and interfaces for RIO drivers.

There's a lot more to do to take advantages of all the hardware features.
However, this should provide a good base for folks with RIO hardware to start
contributing.
