RDMA: Split kernel-only global device caps from uverbs device caps

2022-04-06T18:02:13+00:00

Split out flags from ib_device::device_cap_flags that are only used internally to the kernel into kernel_cap_flags that is not part of the uapi. This limits the device_cap_flags to being the same bitmap that will be copied to userspace. This cleanly splits out the uverbs flags from the kernel flags to avoid confusion in the flags bitmap. Add some short comments describing which each of the kernel flags is connected to. Remove unused kernel flags.

IB/uverbs: Move part of enum ib_device_cap_flags to uapi

2022-04-04T13:58:37+00:00

1) Part of enum ib_device_cap_flags are used by ibv_query_device(3) or ibv_query_device_ex(3), so we define them in include/uapi/rdma/ib_user_verbs.h and only expose them to userspace. 2) Reformat enum ib_device_cap_flags by removing the indent before '='.

Pull rdma updates from Jason Gunthorpe: "Another small cycle. Mostly cleanups and bug fixes, quite a bit assisted from bots. There are a few new syzkaller splats that haven't been solved yet but they should get into the rcs in a few weeks, I think. Summary: - Update drivers to use common helpers for GUIDs, pkeys, bitmaps, memset_startat, and others - General code cleanups from bots - Simplify some of the rxe pool code in preparation for a larger rework - Clean out old stuff from hns, including all support for hip06 devices - Fix a bug where GID table entries could be missed if the table had holes in it - Rename paths and sessions in rtrs for better understandability - Consolidate the roce source port selection code - NDR speed support in mlx5" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (83 commits) RDMA/irdma: Remove the redundant return RDMA/rxe: Use the standard method to produce udp source port RDMA/irdma: Make the source udp port vary RDMA/hns: Replace get_udp_sport with rdma_get_udp_sport RDMA/core: Calculate UDP source port based on flow label or lqpn/rqpn IB/qib: Fix typos RDMA/rtrs-clt: Rename rtrs_clt to rtrs_clt_sess RDMA/rtrs-srv: Rename rtrs_srv to rtrs_srv_sess RDMA/rtrs-clt: Rename rtrs_clt_sess to rtrs_clt_path RDMA/rtrs-srv: Rename rtrs_srv_sess to rtrs_srv_path RDMA/rtrs: Rename rtrs_sess to rtrs_path RDMA/hns: Modify the hop num of HIP09 EQ to 1 IB/iser: Align coding style across driver IB/iser: Remove un-needed casting to/from void pointer IB/iser: Don't suppress send completions IB/iser: Rename ib_ret local variable IB/iser: Fix RNR errors IB/iser: Remove deprecated pi_guard module param IB/mlx5: Expose NDR speed through MAD RDMA/cxgb4: Set queue pair state when being queried ...

RDMA/hns: Support direct wqe of userspace

2021-12-14T23:59:07+00:00

The current write wqe mechanism is to write to DDR first, and then notify the hardware through doorbell to read the data. Direct wqe is a mechanism to fill wqe directly into the hardware. In the case of light load, the wqe will be filled into pcie bar space of the hardware, this will reduce one memory access operation and therefore reduce the latency. SIMD instructions allows cpu to write the 512 bits at one time to device memory, thus it can be used for posting direct wqe. Add direct wqe enable switch and address mapping.
