2019-06-24RDMA/mlx5: Implement mlx5_ib_map_mr_sg_pi and mlx5_ib_alloc_mr_integrityMax Gurtovoy3-11/+189
mlx5_ib_map_mr_sg_pi() will map the PI and data dma mapped SG lists to the mlx5 memory region prior to the registration operation. In the new API, the mlx5 driver will allocate an internal memory region for the UMR operation to register both PI and data SG lists. The internal MR will use KLM mode in order to map 2 (possibly non-contiguous/non-align) SG lists using 1 memory key. In the new API, each ULP will use 1 memory region for the signature operation (instead of 3 in the old API). This memory region will have a key that will be exposed to remote server to perform RDMA operation. The internal memory key that will map the SG lists will stay private.

This is a preparation for the signature verbs API change. This change is needed since the MR type will define, in the upcoming patches, the need for allocating internal resources in LLD for signature handover related operations.

Multiple EQs may share the same irq in subsequent patches. To avoid starvation, a budget is set per EQ's interrupt handler. Because of this change, it is no longer required to check that MLX5_NUM_SPARE_EQE eqes were polled (to detect that arm is required). It is guaranteed that MLX5_NUM_SPARE_EQE > budget, therefore the handler will arm and exit the handler before all the entries in the eq are polled. In the scenario where the handler is out of budget and there are more EQEs to poll, arming the EQ guarantees that the HW will send another interrupt and the handler will be called again.

2019-06-13net/mlx5: Increase wait time for fw initializationDaniel Jurgens1-4/+14
Firmware FLR happens sequentially, in some cases, like when destroying a VM that had many VFs, may require waiting much longer than 10 seconds. Increase the timeout to 2 minutes, and print a wait countdown status every 20 seconds. Signed-off-by: Daniel Jurgens <danielj@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
2019-06-13rdma: Remove nesJason Gunthorpe19-19700/+0
This driver was first merged over 10 years ago and has not seen major activity by the authors in the last 7 years. However, in that time it has been patched 150 times to adapt it to changing kernel APIs. Further, the hardware has several issues, like not supporting 64 bit DMA, that make it rather uninteresting for use with modern systems and RDMA.
