* IB/mlx4: Implement FMRsJack Morgenstein2007-10-091-0/+21
| | | | | | | | Implement FMRs for mlx4. This is an adaptation of code from mthca. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Michael S. Tsirkin <mst@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/mlx4: Display misc device information under /sys/class/infiniband/Jack Morgenstein2007-10-091-0/+6
| | | | | | | | | | | display the following device information under /sys/class/infiniband/mlx4_X: board_id, fw_ver, hw_rev, hca_type. This patch makes this information available to userspace utilities such as ibstat and ibv_devinfo.

* mlx4_core: Get the maximum message size from reported device capabilitiesDotan Barak2007-07-091-0/+1
| | | | | | | | | | Get the maximum message size from the device capabilities returned from the QUERY_DEV_CAP firmware command, rather than hard-coding 2 GB.

* IB/mlx4: Make sure inline data segments don't cross a 64 byte boundaryRoland Dreier2007-06-181-0/+4
| | | | | | | | | | Inline data segments in send WQEs are not allowed to cross a 64 byte boundary. We use inline data segments to hold the UD headers for MLX QPs (QP0 and QP1). A send with GRH on QP1 will have a UD header that is too big to fit in a single inline data segment without crossing a 64 byte boundary, so split the header into two inline data segments.

* IB/mlx4: Handle FW command interface rev 3Roland Dreier2007-06-182-6/+8
| | | | | | | | | | | Upcoming firmware introduces command interface revision 3, which changes the way port capabilities are queried and set. Update the driver to handle both the new and old command interfaces by adding a new MLX4_FLAG_OLD_PORT_CMDS that it is set after querying the firmware interface revision and then using the correct interface based on the setting of the flag.

* IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adaptersRoland Dreier2007-05-087-0/+1118
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.
