* mlx5: Fix mlx5_ib_map_mr_sg mr lengthSagi Grimberg2017-05-25
| | | | | | | | | | | | | | commit 0a49f2c31c3efbeb0de3e4b5598764887f629be2 upstream. In case we got an initial sg_offset, we need to account for it in the mr length.

| | | | | | | | | | | | | | | | | commit 45bded2c216da6010184ac5ebe88c27f73439009 upstream. Make sure that the Q counters are supported by the FW before trying to allocate/deallocte them, this will avoid driver load failure when they aren't supported by the FW.

* IB/mlx5: Avoid system crash when enabling many VFsEli Cohen2017-01-26
| | | | | | | | | | | | | | | | | | | | | | | commit afd02cd3a9b6c04b41d946b5d7f6e17b3fc30c6b upstream. When enabling many VFs, the total amount of DMA mappings increase significantly. This causes DMA allocations to take a lot of time since they are serialized in the kernel. As a result the driver enters into fatal condition due to timeout and the system hangs. To recover from this we disable MR cache for VFs. PFs will still have a full cache and VFs cache can be manipulated as usual after driver load.

"First round of -rc fixes. Due to various issues, I've been away and couldn't send a pull request for about three weeks. There were a number of -rc patches that built up in the meantime (some where there already from the early -rc stages). Obviously, there were way too many to send now, so I tried to pare the list down to the more important patches for the -rc cycle. Most of the code has had plenty of soak time at the various vendor's testing setups, so I doubt there will be another -rc pull request this cycle. I also tried to limit the patches to those with smaller footprints, so even though a shortlog is longer than I would like, the actual diffstat is mostly very small with the exception of just three files that had more changes, and a couple files with pure removals.

| * | IB/mlx5: Fix the size parameter to find_first_bitChristophe Jaillet2016-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 2nd parameter of 'find_first_bit' is the number of bits to search. In this case, we are passing 'sizeof(tmp)' which is likely to be 4 or 8 because 'tmp' is an 'unsigned long'. It is likely that the number of bits of 'tmp' was expected here. So use BITS_PER_LONG instead. It has been spotted by the following coccinelle script: @@ expression ret, x; @@ * ret = \(find_first_bit \| find_first_zero_bit\) (x, sizeof(...)); Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Acked-by: Majd Dibbiny <majd@mellanox.com> Acked-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
