net/mlx5: Synchronize correct IRQ when destroying CQ

2021-08-10T03:57:00Z

The CQ destroy is performed based on the IRQ number that is stored in cq->irqn. That number wasn't set explicitly during CQ creation and as expected some of the API users of mlx5_core_create_cq() forgot to update it. This caused to wrong synchronization call of the wrong IRQ with a number 0 instead of the real one. As a fix, set the IRQ number directly in the mlx5_core_create_cq() and update all users accordingly.

net/mlx5e: Don't create devices during unload flow

2021-06-16T22:36:47Z

Running devlink reload command for port in switchdev mode cause resources to corrupt: driver can't release allocated EQ and reclaim memory pages, because "rdma" auxiliary device had add CQs which blocks EQ from deletion. Erroneous sequence happens during reload-down phase, and is following: 1. detach device - suspends auxiliary devices which support it, destroys others. During this step "eth-rep" and "rdma-rep" are destroyed, "eth" - suspended. 2. disable SRIOV - moves device to legacy mode; as part of disablement - rescans drivers. This step adds "rdma" auxiliary device. 3. destroy EQ table - . Driver shouldn't create any device during unload flows. To handle that implement MLX5_PRIV_FLAGS_DETACH flag, set it on device detach and unset on device attach. If flag is set do no-op on drivers rescan.

net/mlx5: Move chains ft pool to be used by all firmware steering

2021-05-27T18:54:38Z

Firmware FT pool is per device, but the software tracking of this pool only services fs_chains users, and if another layer takes a flow table, the pool will not be updated, and fs_chains will fail creating a flow table, with no recovery till the flow table is returned. Move FT pool to be global per device, and stored at the cmd level, so all layers can use it. Signed-off-by: Paul Blakey Signed-off-by: Saeed Mahameed

{net, RDMA}/mlx5: Fix override of log_max_qp by other device

2021-05-19T06:01:19Z

mlx5_core_dev holds pointer to static profile, hence when the log_max_qp of the profile is override by some device, then it effect all other mlx5 devices that share the same profile. Fix it by having a profile instance for every mlx5 device.
