net/mlx5: Cancel delayed recovery work when unloading the driver

2017-07-21T05:00:06Z

[ Upstream commit 2a0165a034ac024b60cca49c61e46f4afa2e4d98 ] Draining the health workqueue will ignore future health works including the one that report hardware failure and thus we can't enter error state Instead cancel the recovery flow and make sure only recovery flow won't be scheduled.

net/mlx5: Avoid using pending command interface slots

2017-06-07T10:10:03Z

[ Upstream commit 73dd3a4839c1d27c36d4dcc92e1ff44225ecbeb7 ] Currently when firmware command gets stuck or it takes long time to complete, the driver command will get timeout and the command slot is freed and can be used for new commands, and if the firmware receive new command on the old busy slot its behavior is unexpected and this could be harmful. To fix this when the driver command gets timeout we return failure, but we don't free the command slot and we wait for the firmware to explicitly respond to that command. Once all the entries are busy we will stop processing new firmware commands.

Pull Mellanox rdma updates from Doug Ledford: "Mellanox specific updates for 4.11 merge window Because the Mellanox code required being based on a net-next tree, I keept it separate from the remainder of the RDMA stack submission that is based on 4.10-rc3. This branch contains: - Various mlx4 and mlx5 fixes and minor changes - Support for adding a tag match rule to flow specs - Support for cvlan offload operation for raw ethernet QPs - A change to the core IB code to recognize raw eth capabilities and enumerate them (touches non-Mellanox code) - Implicit On-Demand Paging memory registration support" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (40 commits) IB/mlx5: Fix configuration of port capabilities IB/mlx4: Take source GID by index from HW GID table IB/mlx5: Fix blue flame buffer size calculation IB/mlx4: Remove unused variable from function declaration IB: Query ports via the core instead of direct into the driver IB: Add protocol for USNIC IB/mlx4: Support raw packet protocol IB/mlx5: Support raw packet protocol IB/core: Add raw packet protocol IB/mlx5: Add implicit MR support IB/mlx5: Expose MR cache for mlx5_ib IB/mlx5: Add null_mkey access IB/umem: Indicate that process is being terminated IB/umem: Update on demand page (ODP) support IB/core: Add implicit MR flag IB/mlx5: Support creation of a WQ with scatter FCS offload IB/mlx5: Enable QP creation with cvlan offload IB/mlx5: Enable WQ creation and modification with cvlan offload IB/mlx5: Expose vlan offloads capabilities IB/uverbs: Enable QP creation with cvlan offload ...

IB/mlx5: Add implicit MR support

2017-02-14T16:41:19Z

Add implicit MR, covering entire user address space. The MR is implemented as an indirect KSM MR consisting of 1GB direct MRs. Pages and direct MRs are added/removed to MR by ODP. Signed-off-by: Artemy Kovalyov Signed-off-by: Leon Romanovsky Signed-off-by: Doug Ledford

IB/mlx5: Expose MR cache for mlx5_ib

2017-02-14T16:41:18Z

Allow other parts of mlx5_ib to use MR cache mechanism. * Add new functions mlx5_mr_cache_alloc and mlx5_mr_cache_free * Traditional MTT MKey buckets are limited by MAX_UMR_CACHE_ENTRY Additinal buckets may be added above.

IB/mlx5: Add additional checks before processing MADs

2017-02-14T15:14:25Z

Check the has_smi bit in vport context and class version of MADs before allowing MADs processing to take place. MAD_IFC SMI commands can be executed only if smi bit is set.

net/mlx5: Query and cache PCAM, MCAM registers on initialization

2017-01-19T21:19:59Z

On load_one, we now cache our capabilities registers internally, similar to QUERY_HCA_CAP. Capabilities can later be queried using macros introduced in this patch. Signed-off-by: Gal Pressman Signed-off-by: Saeed Mahameed

net/mlx5: Expose PCAM, MCAM registers infrastructure

2017-01-19T21:19:57Z

PCAM: Ports capabilities mask register. MCAM: Management capabilities mask register. PCAM and MCAM registers will provide information regarding firmware support for different features, in order to avoid cases where new driver combined with old firmware results in syndromes (for ex. PCIe counters before this patchset). Signed-off-by: Gal Pressman Signed-off-by: Saeed Mahameed
