This has been a smaller cycle than normal. One new driver was accepted,
which is unusual, and at least one more driver remains in review on the
list.
- Driver fixes for hns, hfi1, nes, rxe, i40iw, mlx5, cxgb4, vmw_pvrdma
- Many patches from MatthewW converting radix tree and IDR users to use
xarray
- Introduction of tracepoints to the MAD layer
- Build large SGLs at the start for DMA mapping and get the driver to
split them
- Generally clean SGL handling code throughout the subsystem
- Support for restricting RDMA devices to net namespaces for containers
- Progress to remove object allocation boilerplate code from drivers
- Change in how the mlx5 driver shows representor ports linked to VFs
- mlx5 uapi feature to access the on chip SW ICM memory
- Add a new driver for 'EFA'. This is HW that supports user space packet
processing through QPs in Amazon's cloud

Userspace InfiniBand Management Datagram (MAD) support. This
|

is the kernel side of the userspace MAD support, which allows

userspace processes to send and receive MADs. You will also

Userspace InfiniBand access support. This enables the
|
|
kernel side of userspace verbs and the userspace
|
|
communication manager (CM). This allows userspace processes
|
|
to set up connections and directly access InfiniBand
|
|
hardware for fast-path operations. You will also need
|
|
libibverbs, libibcm and a hardware driver library from
|

rdma-core <https://github.com/linux-rdma/rdma-core>.

help
|
|
The UCM module has known security flaws, which no one is
|
|
interested to fix. The user-space part of this code was
|
|
dropped from the upstream a long time ago.
|
|
|
|
This option is DEPRECATED and planned to be removed.

IOCTL based uAPI support for Infiniband is enabled by default for
