IB/uverbs: Use anon_inodes instead of private infinibandeventfs

2010-02-25T00:51:20Z

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. Signed-off-by: Roland Dreier

RDMA/addr: Fix build breakage when IPv6 is disabled

2008-12-30T07:37:14Z

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.

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

IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adapters

2007-05-09T01:00:38Z

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 modules

2007-05-09T01:00:37Z

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
