* mlx5: Add driver for Mellanox Connect-IB adaptersEli Cohen2013-07-081-0/+1
| | | | | | | | | | | | | | | | | | | | The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4, except that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core is essentially a library that provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw.

* ib_srpt: Initial SRP Target merge for v3.3-rc1Bart Van Assche2011-12-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the kernel module ib_srpt SCSI RDMA Protocol (SRP) target implementation conforming to the SRP r16a specification for the mainline drivers/target infrastructure. This driver was originally developed by Vu Pham and has been optimized by Bart Van Assche and merged into upstream LIO based on his srpt-lio-4.1 branch here: https://github.com/bvanassche/srpt-lio/commits/srpt-lio-4.1/ This updated patch also contains the following two changes from lio-core-2.6.git/master. One is to fix a bug with 1 >= task->task_sg[] chained mappings in ib_srpt, and the other to convert the configfs control plane to reference IB Port GUID and struct srpt_port directly following mainline v4.x target_core_fabric_configfs.c convertion for ib_srpt to work with rtslib/rtsadmin v2 code.

* IB/uverbs: Use anon_inodes instead of private infinibandeventfsRoland Dreier2010-02-241-0/+1
| | | | | | | | | | The anon_inodes interface has been split to allow creating a bare (non-installed) file pointer and also extended to allow specifying O_RDONLY in the flags. This makes it a suitable replacement for the private "infinibandeventfs" pseudo-filesystem used by uverbs, and this replacement saves a small chunk of boilerplate code.

* RDMA/addr: Fix build breakage when IPv6 is disabledRoland Dreier2008-12-291-0/+1
| | | | | | | | | | | | Commit 38617c64 ("RDMA/addr: Add support for translating IPv6 addresses") broke the build when CONFIG_IPV6=n, because the ib_addr module unconditionally attempted to call ipv6_chk_addr() and other IPv6 functions that are not defined when IPv6 is disabled. Fix this by only building IPv6 support if CONFIG_IPV6 is turned on, and add a Kconfig dependency to prevent the ib_addr code from being built in when IPv6 is built modular.

* 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!
