* IB/mlx4: Implement FMRsJack Morgenstein2007-10-09
| | | | | | | | 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 Morgenstein2007-10-09
| | | | | | | | | | | 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 Barak2007-07-09
| | | | | | | | | | 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: Correct max_srq_wr returned from mlx4_ib_query_device()Jack Morgenstein2007-06-21
| | | | | | | | | | | | | We need to keep a spare entry in the SRQ so that there always is a next WQE available when posting receives (so that we can tell the difference between a full queue and an empty queue). So subtract 1 from the value HW gives us before reporting the limit on SRQ entries to consumers. Found by Mellanox QA.

* IB/mlx4: Handle FW command interface rev 3Roland Dreier2007-06-18
| | | | | | | | | | | 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: Fix uninitialized spinlock for 32-bit archsJack Morgenstein2007-05-14
| | | | | | | | | uar_lock spinlock was used in mlx4_ib_cq_arm without being initialized (this only affects 32-bit archs, because uar_lock is not used on 64-bit archs and MLX4_INIT_DOORBELL_LOCK() is a NOP).

* 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.
