RDMA Driver for the AMD Pensando(R) Ethernet adapter family
===========================================================

AMD Pensando RDMA driver.
Copyright (C) 2018-2025, Advanced Micro Devices, Inc.

Overview
========

The ionic_rdma driver provides Remote Direct Memory Access functionality
for AMD Pensando DSC (Distributed Services Card) devices. This driver
implements RDMA capabilities as an auxiliary driver that operates in
conjunction with the ionic ethernet driver.

The ionic ethernet driver detects RDMA capability during device
initialization and creates auxiliary devices that the ionic_rdma driver
binds to, establishing the RDMA data path and control interfaces.

Identifying the Adapter
=======================

See Documentation/networking/device_drivers/ethernet/pensando/ionic.rst
for more information on identifying the adapter.

Enabling the driver
===================

The ionic_rdma driver depends on the ionic ethernet driver.
See Documentation/networking/device_drivers/ethernet/pensando/ionic.rst
for detailed information on enabling and configuring the ionic driver.

The ionic_rdma driver is enabled via the standard kernel configuration system,
using the make command::

  make oldconfig/menuconfig/etc.

The driver is located in the menu structure at:

  -> Device Drivers
    -> InfiniBand support
      -> AMD Pensando DSC RDMA/RoCE Support

Support
=======

For general Linux RDMA support, please use the RDMA mailing
list, which is monitored by AMD Pensando personnel::
