RDMA/ucma: Add option to manually set IB path

2009-11-16T17:30:33+00:00

Export rdma_set_ib_paths to user space to allow applications to manually set the IB path used for connections. This allows alternative ways for a user space application or library to obtain path record information, including retrieving path information from cached data, avoiding direct interaction with the IB SA. The IB SA is a single, centralized entity that can limit scaling on large clusters running MPI applications. Future changes to the rdma cm can expand on this framework to support the full range of features allowed by the IB CM, such as separate forward and reverse paths and APM.

IB/sa: Add new QoS fields to path record

2007-10-10T02:59:12+00:00

The QoS annex defines new fields for path records. Add them to the ib_sa for consumers that want to use them. Signed-off-by: Sean Hefty Reviewed-by: Or Gerlitz Signed-off-by: Roland Dreier

IB/sa: Track multicast join/leave requests

2007-02-16T22:20:02+00:00

The IB SA tracks multicast join/leave requests on a per port basis and does not do any reference counting: if two users of the same port join the same group, and one leaves that group, then the SA will remove the port from the group even though there is one user who wants to stay a member left. Therefore, in order to support multiple users of the same multicast group from the same port, we need to perform reference counting locally. To do this, add an multicast submodule to ib_sa to perform reference counting of multicast join/leave operations. Modify ib_ipoib (the only in-kernel user of multicast) to use the new interface.

IB/sa: fix ib_sa_selector names

2006-09-22T22:22:55+00:00

Relevant SA queries are actually "greater than" / "less than", not "greater than or equal" / "less than or equal" as the names imply. (See IB spec 1.2 Vol 1, 15.2.5.16 PATHRECORD/Table 205 PathRecord) Signed-off-by: Michael S. Tsirkin Signed-off-by: Roland Dreier

IB/sa: Require SA registration

2006-09-22T22:22:53+00:00

Require users to register with SA module, to prevent the sa_query module text from going away while an SA query callback is still running. Update all in-tree users for the new interface. Signed-off-by: Michael S. Tsirkin Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

IB/sa: Add ib_init_ah_from_path()

2006-06-18T03:37:39+00:00

Add a call to initialize address handle attributes given a path record. This is used by the CM, and would be useful for users of UD QPs. Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

IB: simplify static rate encoding

2006-04-10T16:43:47+00:00

Push translation of static rate to HCA format into low-level drivers, where it belongs. For static rate encoding, use encoding of rate field from IB standard PathRecord, with addition of value 0, for backwards compatibility with current usage. The changes are: - Add enum ib_rate to midlayer includes. - Get rid of static rate translation in IPoIB; just use static rate directly from Path and MulticastGroup records. - Update mthca driver to translate absolute static rate into the format used by hardware. This also fixes mthca's static rate handling for HCAs that are capable of 4X DDR. Signed-off-by: Jack Morgenstein Signed-off-by: Roland Dreier

[PATCH] gfp flags annotations - part 1

2005-10-08T22:00:57+00:00

- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.
