2019-04-18IB/mlx5: Fix scatter to CQE in DCT QP creationGuy Levi1-0/+2
When scatter to CQE is enabled on a DCT QP it corrupts the mailbox command since it tried to treat it as as QP create mailbox command instead of a DCT create command. The corrupted mailbox command causes userspace to malfunction as the device doesn't create the QP as expected. A new mlx5 capability is exposed to user-space which ensures that it will not enable the feature on DCT without this fix in the kernel.

This merge commit includes some misc shared code updates from mlx5-next branch needed for net-next. 1) From Maxim, Remove un-used macros and spinlock from mlx5 code. 2) From Aya, Expose Management PCIE info register layout and add rate limit print macros. 3) From Tariq, Compilation warning fix in fs_core.c 4) From Vu, Huy and Saeed, Improve mlx5 initialization flow: The goal is to provide a better logical separation of mlx5 core device initialization flow and will help to seamlessly support creating different mlx5 device types such as PF, VF and SF mlx5 sub-function virtual devices. Mlx5_core driver needs to separate HCA resources from pci resources. Its initialize/load/unload will be broken into stages: 1. Initialize common data structures 2. Setup function which initializes pci resources (for PF/VF) or some other specific resources for virtual device 3. Initialize software objects according to hardware capabilities 4. Load all mlx5_core components It is also necessary to detach mlx5_core mdev name/message from pci device mdev->pdev name/message for a clearer report/debug of different mlx5 device types.

2019-02-21IB/mlx5: Protect against prefetch of invalid MRMoni Shoua1-12/+1
When deferring a prefetch request we need to protect against MR or PD being destroyed while the request is still enqueued. The first step is to validate that PD owns the lkey that describes the MR and that the MR that the lkey refers to is owned by that PD. The second step is to dequeue all requests when MR is destroyed. Since PD can't be destroyed while it owns MRs it is guaranteed that when a worker wakes up the request it refers to is still valid. Now, it is possible to refrain from taking a reference on the device since it is assured to be present as pd. While that, replace the dedicated ordered workqueue with the system unbound workqueue to reuse an existing resource and improve performance. This will also fix a bug of queueing to the wrong workqueue.

2018-12-18IB/mlx5: Add advise_mr() supportMoni Shoua1-0/+8
The verb advise_mr() is used to give advice to the kernel about an address range that belongs to a MR. Implement the verb and register it on the device. The current implementation supports the only known advice to date, prefetch.

2018-12-14net/mlx5: Make RoCE and SR-IOV LAG modes explicitAviv Heller1-5/+8
With the introduction of SR-IOV LAG, checking whether LAG is active is no longer good enough, since RoCE and SR-IOV LAG each entails different behavior by both the core and infiniband drivers. This patch introduces facilities to discern LAG type, in addition to mlx5_lag_is_active(). These are implemented in such a way as to allow more complex mode combinations in the future.

2018-12-14IB/mlx5: Unify e-switch representors load approach between uplink and VFsMark Bloch1-20/+9
When in switchdev mode and the add function is called by the core level driver, make sure we only register the callbacks, but don't create the mlx5 IB device or initialize anything. With this change all the IB devices in switchdev mode are created only once the load callback is invoked by the e-switch core sub-module. This follows the design paradigm under which the all the Eth representors must be loaded before any of IB reprs is loaded.
