* IB/mlx4: Fix race when detaching a QP from a multicast groupEli Cohen2008-04-17
| | | | | | | | | | | | | | When detaching the last QP from an MCG entry, we need to make sure that at any time, there will be no entry with zero number of QPs which is linked to the list of the MCGs of the corresponding hash index. So don't write back the MCG entry if we are removing the last QP; just unlink the entry. Also, remove an unnecessary MCG read when attaching a QP requires allocation of a new entry in the AMGM.

* mlx4_core: Fix section mismatchesRoland Dreier2007-10-10
| | | | | | | | | | | | Commit ee49bd93 ("mlx4_core: Reset device when internal error is detected") introduced some section mismatch problems when CONFIG_HOTPLUG=n, because the error recovery code tears down and reinitializes the device after everything is loaded, which ends up calling into lots of code marked __devinit and __devexit from regular .text. Fix this by getting rid of these now-incorrect section markers. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adaptersRoland Dreier2007-05-08
Add an InfiniBand driver for Mellanox ConnectX adapters. Because these adapters can also be used as ethernet NICs and Fibre Channel HBAs, the driver is split into two modules: mlx4_core: Handles low-level things like device initialization and processing firmware commands. Also controls resource allocation so that the InfiniBand, ethernet and FC functions can share a device without stepping on each other. mlx4_ib: Handles InfiniBand-specific things; plugs into the InfiniBand midlayer.
