* RDMA: Convert drivers to use the AH's sgid_attr in post_wr pathsParav Pandit2018-06-181-4/+1
| | | | | | | | | | For UD the drivers were doing a sgid_index lookup into the cache to get the attrs, however we can now directly access the same attrs stores in the ib_ah instead and remove the lookup.

* IB/core: Define 'ib' and 'roce' rdma_ah_attr typesDasaratharaman Chandramouli2017-05-011-0/+1
| | | | | | | | | | | | | | | | rdma_ah_attr can now be either ib or roce allowing core components to use one type or the other and also to define attributes unique to a specific type. struct ib_ah is also initialized with the type when its first created. This ensures that calls such as modify_ah dont modify the type of the address handle attribute.

* IB/core: Rename struct ib_ah_attr to rdma_ah_attrDasaratharaman Chandramouli2017-05-011-2/+2
| | | | | | | | | | | | | This patch simply renames struct ib_ah_attr to rdma_ah_attr as these fields specify attributes that are not necessarily specific to IB.

* IB/mthca: Set GRH:HopLimit when building MLX headersRolf Manderscheid2007-05-191-0/+1
| | | | | | | | | | | Global CM packets used by rmda_cm were being sent with a GRH:hopLimit of zero, causing them to be dropped by the router. The problem is a missing initialization of the hop_limit field in mthca_read_ah(), which was called by build_mlx_header() when sending a MAD on QP1.

* IB/mthca: Fix section mismatchesRoland Dreier2006-11-291-2/+1
| | | | | | | | | | | | | Commit b3b30f5e ("IB/mthca: Recover from catastrophic errors") introduced some section mismatch breakage, because the error recovery code tears down and reinitializes the device, which calls into lots of code originally marked __devinit and __devexit from regular .text. Fix this by getting rid of these now-incorrect section markers. Reported by Randy Dunlap <randy.dunlap@oracle.com>. Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB: simplify static rate encodingJack Morgenstein2006-04-101-1/+99
| | | | | | | | | | | | | | | | | 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 <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* [PATCH] fix missing includesTim Schmielau2005-10-301-0/+2
| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
