* mlx4_core: Add support for multiple completion event vectorsYevgeny Petrilin2008-12-22
| | | | | | | | | | | When using MSI-X mode, create a completion event queue for each CPU. Report the number of completion EQs in a new struct mlx4_caps member, num_comp_vectors, and extend the mlx4_cq_alloc() interface with a vector parameter so that consumers can specify which completion EQ should be used to report events for the CQ being created.

* mlx4_core: Support multiple pre-reserved QP regionsYevgeny Petrilin2008-10-22
| | | | | | | | | | | | | 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: Add a way to set the "collapsed" CQ flagYevgeny Petrilin2008-04-29
| | | | | | | | Extend the mlx4_cq_resize() API with a way to set the "collapsed" flag for the CQ being created. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* mlx4_core: CQ resizing should pass a 0 opcode modifier to MODIFY_CQVladimir Sokolovsky2008-04-23
| | | | | | | | | The call to mlx4_MODIFY_CQ() had a typo so that mlx4_cq_resize() was actually asking the FW to modify a CQ's interrupt moderation rather than asking it to resize a CQ. Signed-off-by: Vladimir Sokolovsky <vlad@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* 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>
* mlx4_core: Fix CQ context layoutEli Cohen2007-06-07
| | | | | | | | | | | The reserved6 field should be 64 bits, not just 16 bits. Without this, the structure does not match the hardware layout on 32-bit architectures: the db_rec_addr field ends up at offset 52 instead of offset 56. The bug slipped by because the alignment of __be64 members ends up putting it in the right place on x86-64.

* 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.
