RDMA/hns: Add compatibility handling for only support userspace rq inline

2023-01-09T14:45:28Z

The rq inline makes some changes as follows, Firstly, it is only used in user space. Secondly, it should notify hardware in QP RTR status. Thirdly, Add compatibility processing between different user space and kernel space.

RDMA/rxe: Extend rxe user ABI to support flush

2022-12-09T23:36:01Z

This commit extends the rxe user ABI to support the flush operation defined in IBA A19.4.1. These changes are backward compatible with the existing rxe user ABI. The user API request a flush by filling this structure.

RDMA/hns: Fix incorrect sge nums calculation

2022-11-19T00:19:49Z

The user usually configures the number of sge through the max_send_sge parameter when creating qp, and configures the maximum size of inline data that can be sent through max_inline_data. Inline uses sge to fill data to send. Expect the following: 1) When the sge space cannot hold inline data, the sge space needs to be expanded to accommodate all inline data 2) When the sge space is enough to accommodate inline data, the upper limit of inline data can be increased so that users can send larger inline data Currently case one is not implemented. When the inline data is larger than the sge space, an error of insufficient sge space occurs. This part of the code needs to be reimplemented according to the expected rules. The calculation method of sge num is modified to take the maximum value of max_send_sge and the sge for max_inline_data to solve this problem. Fixes: 05201e01be93 ("RDMA/hns: Refactor process of setting extended sge") Fixes: 30b707886aeb ("RDMA/hns: Support inline data in extented sge space for RC") Link: https://lore.kernel.org/r/20221108133847.2304539-3-xuhaoyue1@hisilicon.com Signed-off-by: Luoyouming Signed-off-by: Haoyue Xu Signed-off-by: Jason Gunthorpe

RDMA/rxe: Remove redundant num_sge fields

2022-09-27T13:15:24Z

In include/uapi/rdma/rdma_user_rxe.h there are redundant copies of num_sge in the rxe_send_wr, rxe_recv_wqe, and rxe_dma_info. Only the ones in rxe_dma_info are actually used by the rxe kernel driver. The userspace would set these values, but the kernel never read them. This change has no affect on the current ABI and new or old versions of rdma-core operate correctly with new or old versions of the kernel rxe driver.

RDMA/mlx5: Add support for dmabuf to devx umem

2022-09-27T13:15:24Z

This is modeled after the similar EFA enablement in commit 66f4817b5712 ("RDMA/efa: Add support for dmabuf memory regions"). Like EFA there is no support for revocation so we simply call the ib_umem_dmabuf_get_pinned() to obtain a umem instead of the normal ib_umem_get(). Everything else stays the same.
