IB/mlx5: Fix MODIFY_QP command input structure

2016-11-20T01:16:41+00:00

commit e3353c268b06236d6c40fa1714c114f21f44451c upstream.

IB/mlx5: Fix post send fence logic

2016-08-22T21:38:18+00:00

commit c9b254955b9f8814966f5dabd34c39d0e0a2b437 upstream. If the caller specified IB_SEND_FENCE in the send flags of the work request and no previous work request stated that the successive one should be fenced, the work request would be executed without a fence. This could result in RDMA read or atomic operations failure due to a MR being invalidated. Fix this by adding the mlx5 enumeration for fencing RDMA/atomic operations and fix the logic to apply this.

IB/mlx5: Collect signature error completion

2014-03-07T19:40:04+00:00

This commit takes care of the generated signature error CQE generated by the HW (if happened). The underlying mlx5 driver will handle signature error completions and will mark the relevant memory region as dirty. Once the consumer gets the completion for the transaction, it must check for signature errors on signature memory region using a new lightweight verb ib_check_mr_status(). In case the user doesn't check for signature error (i.e. doesn't call ib_check_mr_status() with status check IB_MR_CHECK_SIG_STATUS), the memory region cannot be used for another signature operation (REG_SIG_MR work request will fail).

IB/mlx5: Support IB_WR_REG_SIG_MR

2014-03-07T19:39:51+00:00

This patch implements IB_WR_REG_SIG_MR posted by the user. Baisically this WR involves 3 WQEs in order to prepare and properly register the signature layout: 1. post UMR WR to register the sig_mr in one of two possible ways: * In case the user registered a single MR for data so the UMR data segment consists of: - single klm (data MR) passed by the user - BSF with signature attributes requested by the user. * In case the user registered 2 MRs, one for data and one for protection, the UMR consists of: - strided block format which includes data and protection MRs and their repetitive block format. - BSF with signature attributes requested by the user. 2. post SET_PSV in order to set the memory domain initial signature parameters passed by the user. SET_PSV is not signaled and solicited CQE. 3. post SET_PSV in order to set the wire domain initial signature parameters passed by the user. SET_PSV is not signaled and solicited CQE. * After this compound WR we place a small fence for next WR to come. This patch also introduces some helper functions to set the BSF correctly and determining the signature format selectors. Signed-off-by: Sagi Grimberg Signed-off-by: Roland Dreier

IB/mlx5: Initialize mlx5_ib_qp signature-related members

2014-03-07T19:26:49+00:00

If user requested signature enable we initialize relevant mlx5_ib_qp members. We mark the qp as sig_enable and we increase the effective SQ size, but still limit the user max_send_wr to original size computed. We also allow the create_qp routine to accept sig_enable create flag. Signed-off-by: Sagi Grimberg Signed-off-by: Roland Dreier

mlx5_core: Improve debugfs readability

mlx5: Add driver for Mellanox Connect-IB adapters

2013-07-08T17:32:24+00:00

The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4, except that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core is essentially a library that provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw.
