* mlx4_core: Add a way to set the "collapsed" CQ flagYevgeny Petrilin2008-04-291-1/+3
| | | | | | | | 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 Sokolovsky2008-04-231-1/+1
| | | | | | | | | 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 Dreier2007-10-101-1/+1
| | | | | | | | | | | | 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 Cohen2007-06-071-1/+1
| | | | | | | | | | | 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 Dreier2007-05-081-0/+254
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.
