* IB: Use menuconfig for InfiniBand menuJan Engelhardt2007-07-091-8/+7
| | | | | | | | | | Change Kconfig objects from "menu, config" into "menuconfig" so that the user can disable the whole feature without having to enter the menu first.

* [S390] Kconfig: menus with depends on HAS_IOMEM.Martin Schwidefsky2007-05-101-0/+1
| | | | | | | Add "depends on HAS_IOMEM" to a number of menus to make them disappear for s390 which does not have I/O memory. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adaptersRoland Dreier2007-05-081-0/+2
| | | | | | | | | | | | | | | | 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.

* IB/uverbs: Export ib_umem_get()/ib_umem_release() to modulesRoland Dreier2007-05-081-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Export ib_umem_get()/ib_umem_release() and put low-level drivers in control of when to call ib_umem_get() to pin and DMA map userspace, rather than always calling it in ib_uverbs_reg_mr() before calling the low-level driver's reg_user_mr method. Also move these functions to be in the ib_core module instead of ib_uverbs, so that driver modules using them do not depend on ib_uverbs. This has a number of advantages: - It is better design from the standpoint of making generic code a library that can be used or overridden by device-specific code as the details of specific devices dictate. - Drivers that do not need to pin userspace memory regions do not need to take the performance hit of calling ib_mem_get(). For example, although I have not tried to implement it in this patch, the ipath driver should be able to avoid pinning memory and just use copy_{to,from}_user() to access userspace memory regions. - Buffers that need special mapping treatment can be identified by the low-level driver. For example, it may be possible to solve some Altix-specific memory ordering issues with mthca CQs in userspace by mapping CQ buffers with extra flags. - Drivers that need to pin and DMA map userspace memory for things other than memory regions can use ib_umem_get() directly, instead of hacks using extra parameters to their reg_phys_mr method. For example, the mlx4 driver that is pending being merged needs to pin and DMA map QP and CQ buffers, but it does not need to create a memory key for these buffers. So the cleanest solution is for mlx4 to call ib_umem_get() in the create_qp and create_cq methods. Signed-off-by: Roland Dreier <rolandd@cisco.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
