RDMA/rxe: Move the definitions for rxe_av.network_type to uAPI

2020-10-16T16:54:10Z

RXE was wrongly using an internal kernel enum as part of its uAPI, split this out into a dedicated uAPI enum just for RXE. It only uses the IPv4 and IPv6 values. This was exposed by changing the internal kernel enum definition which broke RXE. Fixes: 1c15b4f2a42f ("RDMA/core: Modify enum ib_gid_type and enum rdma_network_type") Signed-off-by: Jason Gunthorpe

RDMA/uverbs: Expose the new GID query API to user space

2020-10-02T00:20:11Z

Expose the query GID table and entry API to user space by adding two new methods and method handlers to the device object. This API provides a faster way to query a GID table using single call and will be used in libibverbs to improve current approach that requires multiple calls to open, close and read multiple sysfs files for a single GID table entry.

RDMA/core: Introduce new GID table query API

2020-10-02T00:20:11Z

Introduce rdma_query_gid_table which enables querying all the GID tables of a given device and copying the attributes of all valid GID entries to a provided buffer. This API provides a faster way to query a GID table using single call and will be used in libibverbs to improve current approach that requires multiple calls to open, close and read multiple sysfs files for a single GID table entry.

RDMA/mlx5: Extend advice MR to support non faulting mode

2020-10-01T19:44:05Z

Extend advice MR to support non faulting mode, this can improve performance by increasing the populated page tables in the device. Link: https://lore.kernel.org/r/20200930163828.1336747-4-leon@kernel.org Signed-off-by: Yishai Hadas Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/hns: Add support for CQE in size of 64 Bytes

2020-09-24T18:35:11Z

The new version of RoCEE supports using CQE in size of 32B or 64B. The performance of bus can be improved by using larger size of CQE.

RDMA/core: Added missing WR and WC opcodes

2020-09-11T13:24:54Z

Add work completion opcodes to a new ib_uverbs_wc_opcode enum in ib_user_verbs.h. This plays the same role as ib_uverbs_wr_opcode documenting the opcodes in the user space API. Assigned the IB_WC_XXX opcodes in ib_verbs.h to the IB_UVERBS_WC_XXX where they are defined. This follows the same pattern as the IB_WR_XXX opcodes. This fixes an incorrect value for LSO that had crept in but is not currently being used. Added a missing IB_WR_BIND_MW opcode in ib_verbs.h.

RDMA/efa: Introduce SRD RNR retry

2020-08-18T17:52:45Z

This patch introduces the ability to configure SRD QPs with the RNR retry parameter when issuing a modify QP command. In addition, a capability bit was added to report support to the userspace library.

RDMA/efa: User/kernel compatibility handshake mechanism

2020-07-29T12:23:40Z

Introduce a mechanism that performs an handshake between the userspace provider and kernel driver which verifies that the user supports all required features in order to operate correctly. The handshake verifies the needed functionality by comparing the reported device caps and the provider caps. If the device reports a non-zero capability the appropriate comp mask is required from the userspace provider in order to allocate the context.
