linux-toradex.git/include/linux/mlx4, branch v2.6.27.50 Linux kernel for Apalis and Colibri modules IB/mlx4: Add strong ordering to local inval and fast reg work requests 2009-07-02T23:31:47+00:00 Jack Morgenstein jackm@dev.mellanox.co.il 2009-06-05T17:36:24+00:00 ef01dc931edee0aff13604a74c9debb518bcc88c commit 2ac6bf4ddc87c3b6b609f8fa82f6ebbffeac12f4 upstream. The ConnectX Programmer's Reference Manual states that the "SO" bit must be set when posting Fast Register and Local Invalidate send work requests. When this bit is set, the work request will be executed only after all previous work requests on the send queue have been executed. (If the bit is not set, Fast Register and Local Invalidate WQEs may begin execution too early, which violates the defined semantics for these operations) This fixes the issue with NFS/RDMA reported in <http://lists.openfabrics.org/pipermail/general/2009-April/059253.html> Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> 
commit 2ac6bf4ddc87c3b6b609f8fa82f6ebbffeac12f4 upstream.

The ConnectX Programmer's Reference Manual states that the "SO" bit
must be set when posting Fast Register and Local Invalidate send work
requests.  When this bit is set, the work request will be executed
only after all previous work requests on the send queue have been
executed.  (If the bit is not set, Fast Register and Local Invalidate
WQEs may begin execution too early, which violates the defined
semantics for these operations)

This fixes the issue with NFS/RDMA reported in

IB/mlx4: Fix up fast register page list format 2008-09-15T21:25:23+00:00 Vladimir Sokolovsky vlad@mellanox.co.il 2008-09-15T21:25:23+00:00 29bdc88384c2b24e37e5760df0dc898546083d6b Byte swap the addresses in the page list for fast register work requests to big endian to match what the HCA expectx. Also, the addresses must have the "present" bit set so that the HCA knows it can access them. Otherwise the HCA will fault the first time it accesses the memory region.
