Merge branch 'mlx5_tir_icm' into rdma.git for-next

Ariel Levkovich says: ==================== The series exposes the ICM address of the receive transport interface (TIR) of Raw Packet and RSS QPs to the user since they are required to properly create and insert steering rules that direct flows to these QPs. ==================== For dependencies this branch is based on mlx5-next from git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux * branch 'mlx5_tir_icm': IB/mlx5: Expose TIR ICM address to user space net/mlx5: Introduce new TIR creation core API net/mlx5: Expose TIR ICM address in command outbox Signed-off-by: Jason Gunthorpe

IB/mlx5: Expose TIR ICM address to user space

2019-04-25T13:03:19Z

This patch exposes the TIR ICM address of raw packet and RSS QPs to user space. In order to pass the new field, the patch extends the mlx5 specific QP creation response structure and fills it with the icm address returned by the FW command, if available.

IB/mlx5: Fix scatter to CQE in DCT QP creation

2019-04-18T06:13:41Z

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.

IB/mlx5: Add packet based credit mode support

2018-12-07T20:22:09Z

The device can support two credit modes, message based (default) and packet based. In order to enable packet based mode, the QP should be created with special flag that indicates this. This patch adds support for the new DV QP creation flag that can be used for RC QPs in order to change the credit mode.

IB/mlx5: Allow scatter to CQE without global signaled WRs

2018-10-17T15:25:41Z

Requester scatter to CQE is restricted to QPs configured to signal all WRs. This patch adds ability to enable scatter to cqe (force enable) in the requester without sig_all, for users who do not want all WRs signaled but rather just the ones whose data found in the CQE.

IB/mlx5: Expose RAW QP device handles to user space

Expose RAW QP device handles to user space by extending the UHW part of mlx5_ib_create_qp_resp. This data is returned only when DEVX context is used where it may be applicable. Signed-off-by: Yishai Hadas Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/mlx5: Allow creating RAW ethernet QP with loopback support

2018-09-22T00:20:59Z

Expose two new flags: MLX5_QP_FLAG_TIR_ALLOW_SELF_LB_UC MLX5_QP_FLAG_TIR_ALLOW_SELF_LB_MC Those flags can be used at creation time in order to allow a QP to be able to receive loopback traffic (unicast and multicast). We store the state in the QP to be used on the destroy path to indicate with which flags the QP was created with.

IB/mlx5: Expose dump and fill memory key

2018-07-04T19:16:04Z

MLX5 IB HCA offers the memory key, dump_fill_mkey to boost performance, when used in a send or receive operations. It is used to force local HCA operations to skip the PCI bus access, while keeping track of the processed length in the ibv_sge handling. Meaning, instead of a PCI write access the HCA leaves the target memory untouched, and skips filling that packet section. Similar behavior is done upon send, the HCA skips data in memory relevant to this key and saves PCI bus access. This functionality saves PCI read/write operations.
