mlx4_core: Fix build break (missing include)

2008-02-11T22:19:42Z

Commit 313abe55 ("mlx4_core: For 64-bit systems, vmap() kernel queue buffers") caused this to pop up on powerpc allyesconfig, looks like a missing include file: drivers/net/mlx4/alloc.c: In function 'mlx4_buf_alloc': drivers/net/mlx4/alloc.c:162: error: implicit declaration of function 'vmap' drivers/net/mlx4/alloc.c:162: error: 'VM_MAP' undeclared (first use in this function) drivers/net/mlx4/alloc.c:162: error: (Each undeclared identifier is reported only once drivers/net/mlx4/alloc.c:162: error: for each function it appears in.) drivers/net/mlx4/alloc.c:162: warning: assignment makes pointer from integer without a cast drivers/net/mlx4/alloc.c: In function 'mlx4_buf_free': drivers/net/mlx4/alloc.c:187: error: implicit declaration of function 'vunmap' Signed-off-by: Olof Johansson Signed-off-by: Roland Dreier

mlx4_core: Clean up struct mlx4_buf

2008-02-07T05:17:59Z

Now that struct mlx4_buf.u is a struct instead of a union because of the vmap() changes, there's no point in having a struct at all. So move .direct and .page_list directly into struct mlx4_buf and get rid of a bunch of unnecessary ".u"s. Signed-off-by: Roland Dreier

mlx4_core: For 64-bit systems, vmap() kernel queue buffers

2008-02-07T05:17:45Z

Since kernel virtual memory is not a problem on 64-bit systems, there is no reason to use our own 2-layer page mapping scheme for large kernel queue buffers on such systems. Instead, map the page list to a single virtually contiguous buffer with vmap(), so that can we access buffer memory via direct indexing. Signed-off-by: Michael S.

mlx4_core: Fix possible bad free in mlx4_buf_free()

2007-11-13T23:26:57Z

When mlx4_buf_free() is called from the error path of mlx4_buf_alloc(), it may be passed a buffer structure that does not have all pages filled in. Add a check for NULL to mlx4_buf_free() so we avoid passing NULL to dma_free_coherent() (which will crash). Signed-off-by: Ali Ayoub Signed-off-by: Jack Morgenstein Signed-off-by: Roland Dreier

IB/mlx4: Fix last allocated object tracking in bitmap allocator

2007-05-29T23:07:09Z

Set last allocated object to the object after the one just allocated before ORing in the extra top bits. Also handle the case where this wraps around. Signed-off-by: Roland Dreier

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.
