2007-10-24SG: Change sg_set_page() to take length and offset argumentJens Axboe
Most drivers need to set length and offset as well, so may as well fold those three lines into one. Add sg_assign_page() for those two locations that only needed to set the page, where the offset/length is set outside of the function context. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-10-09mlx4_core: Write MTTs from CPU instead with of WRITE_MTT FW commandJack Morgenstein
Write MTT entries directly to ICM from the driver (eliminating use of WRITE_MTT command). This reduces the number of FW commands needed to register an MR by at least a factor of 2 and speeds up memory registration significantly. This code will also be used to implement FMRs.

2007-10-09mlx4_core: Support ICM tables in coherent memoryJack Morgenstein
Enable having ICM tables in coherent memory, and use coherent memory for the dMPT table. This will allow writing MPT entries for MRs both via the SW2HW_MPT command and also directly by the driver for FMR remapping without needing to flush or worry about cacheline boundaries.

2007-05-08IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adaptersRoland Dreier
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.
