mlx4: Move the Mellanox driver

2011-08-11T09:41:35+00:00

Moves the Mellanox driver into drivers/net/ethernet/mellanox/ and make the necessary Kconfig and Makefile changes. CC: Roland Dreier Signed-off-by: Jeff Kirsher

mlx4_core: reserve UARs for userspace consumers

2011-03-23T19:24:24+00:00

Do not allow a kernel consumer to allocate a UAR to serve for blue flame if the number of available UARs gets below MLX4_NUM_RESERVED_UARS (currently 8). This will allow userspace apps to open a device file and run things like ibv_devinfo. Signed-off-by: Eli Cohen Signed-off-by: David S. Miller

mlx4: Add blue flame support for kernel consumers

2011-03-23T19:24:23+00:00

Using blue flame can improve latency by allowing the HW to more efficiently access the WQE. This patch presents two functions that are used to allocate or release HW resources for using blue flame; the caller need to supply a struct mlx4_bf object when allocating resources. Consumers that make use of this API should post doorbells to the UAR object pointed by the initialized struct mlx4_bf; Signed-off-by: Eli Cohen Signed-off-by: David S. Miller

mlx4_core: Remove unnecessary includes of

2009-09-06T03:24:49+00:00

Lots of mlx4 files with no function annotations included for no reason. Signed-off-by: Roland Dreier

mlx4_core: Support multiple pre-reserved QP regions

2008-10-22T17:25:29+00:00

For ethernet support, we need to reserve QPs for the ethernet and fibre channel driver. The QPs are reserved at the end of the QP table. (This way we assure that they are aligned to their size) We need to consider these reserved ranges in bitmap creation, so we extend the mlx4 bitmap utility functions to allow reserved ranges at both the bottom and the top of the range.

mlx4_core: Improve error message when not enough UAR pages are available

2008-07-23T15:12:47+00:00

If an mlx4 device with default FW (which gives a UAR BAR size of 8 MB) is used in a system with 64 KB pages, then there are only 8192/64==128 UAR pages available. However, the first 128 UAR pages are reserved for use with event queue doorbells, so no UAR pages are available to do anything else with, which means that the driver cannot work. The current driver fails with a fairly cryptic "Failed to allocate driver access region, aborting" message in this situation. Fix the driver to detect the problem earlier and print out a clearer description of the problem and a suggestion of how to fix it (use a new firmware image). Signed-off-by: Roland Dreier

mlx4_core: Fix section mismatches

2007-10-10T22:43:54+00:00

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

IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adapters

2007-05-09T01:00:38+00:00

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.
