2008-04-16IB/ipath: Enable 4KB MTUDave Olson
Enable use of 4KB MTU. Since the driver uses more pinned memory for receive buffers when the 4KB MTU is enabled, whether or not the fabric supports that MTU, add a "mtu4096" module parameter that can be used to limit the MTU to 2KB when it is known that 4KB MTUs can't be used anyway.

2008-04-16IB/ipath: Provide I/O bus speeds for diagnostic purposesArthur Jones
Modern I/O buses like PCIe and HT can be configured for multiple speeds and widths. When an ipath HCA seems to have lower than expected performance, it is very useful to be able to display what the driver thinks the bus speed is.

2008-04-16IB/ipath: Misc sparse warning cleanupArthur Jones
Recent sparse versions and kernel cleanups knock down the false positive rate of the ipath driver code to a point where having it be sparse clean is worthwhile. Here we fixup the sparse warnings. Some of these warnings (and the impetus to run sparse again) are due to work by Roland Dreier. Signed-off-by: Arthur Jones <arthur.jones@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-04-16IB/mthca: Add IPoIB checksum offload supportEli Cohen
Arbel and Sinai devices support checksum generation and verification of TCP and UDP packets for UD IPoIB messages. This patch checks if the HCA supports this and sets the IB_DEVICE_UD_IP_CSUM capability flag if it does. It implements support for handling the IB_SEND_IP_CSUM send flag and setting the csum_ok field in receive work completions.

2008-04-16RDMA/nes: Use proper format and cast to print dma_addr_tRoland Dreier
On some platforms, eg sparc64, dma_addr_t is not the same size as a pointer, so printing dma_addr_t values by casting to void * and using a %p format generates warnings. Fix this by casting to unsigned long and using %lx instead. This fixes the warnings: drivers/infiniband/hw/nes/nes_verbs.c: In function 'nes_setup_virt_qp': drivers/infiniband/hw/nes/nes_verbs.c:1047: warning: cast to pointer from integer of different size drivers/infiniband/hw/nes/nes_verbs.c:1078: warning: cast to pointer from integer of different size drivers/infiniband/hw/nes/nes_verbs.c:1078: warning: cast to pointer from integer of different size drivers/infiniband/hw/nes/nes_verbs.c: In function 'nes_reg_user_mr': drivers/infiniband/hw/nes/nes_verbs.c:2657: warning: cast to pointer from integer of different size Reported by Andrew Morton <akpm@linux-foundation.org>.

2008-04-16RDMA/nes: Remove redundant NULL check in nes_unregister_ofa_device()Roland Dreier
nes_unregister_ofa_device() dereferences the nesibdev pointer before testing if it's NULL. Also, the test is doubly redundant because the only caller of nes_unregister_ofa_device() is nes_destroy_ofa_device(), which already tests if nesibdev is NULL. Remove the unnecessary test. This was spotted by the Coverity checker (CID 2190). Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-04-16IB/uverbs: Use alloc_file() instead of get_empty_filp()Roland Dreier
Christoph Hellwig wants to unexport get_empty_filp(), which is an ugly internal interface. Change the modular user in ib_uverbs_alloc_event_file() to use the better alloc_file() interface; this makes the code cleaner too. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-04-16IB/uverbs: Don't store struct file * for event filesRoland Dreier
The file member of struct ib_uverbs_event_file was only used to keep track of whether the file had been closed or not. The only thing we ever did with the value was check if it was NULL or not. Simplify the code and get rid of the need to keep track of the struct file * we allocate by replacing the file member with an is_closed member. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-04-16mlx4_core: Fix confusion between mlx4_event and mlx4_dev_event enumsRoland Dreier
The struct mlx4_interface.event() method was supposed to get an enum mlx4_dev_event, but the driver code was actually passing in the hardware enum mlx4_event values. Fix up the callers of mlx4_dispatch_event() so that they pass in the right type of value, and fix up the event method in mlx4_ib so that it can handle the enum mlx4_dev_event values. This eliminates the need for the subtype parameter to the event method, so remove it. This also fixes the sparse warning drivers/net/mlx4/intf.c:127:48: warning: mixing different enum types drivers/net/mlx4/intf.c:127:48: int enum mlx4_event versus drivers/net/mlx4/intf.c:127:48: int enum mlx4_dev_event Signed-off-by: Roland Dreier <rolandd@cisco.com>
