RDMA Support via Auxiliary Device
110+
=================================
111+
112+
The ionic driver supports RDMA (Remote Direct Memory Access) functionality
113+
through the Linux auxiliary device framework when advertised by the firmware.
114+
RDMA capability is detected during device initialization, and if supported,
115+
the ethernet driver will create an auxiliary device that allows the RDMA
116+
driver to bind and provide InfiniBand/RoCE functionality.

Overview
11+
========
12+
13+
The ionic_rdma driver provides Remote Direct Memory Access functionality
14+
for AMD Pensando DSC (Distributed Services Card) devices. This driver
15+
implements RDMA capabilities as an auxiliary driver that operates in
16+
conjunction with the ionic ethernet driver.
17+
18+
The ionic ethernet driver detects RDMA capability during device
19+
initialization and creates auxiliary devices that the ionic_rdma driver
20+
binds to, establishing the RDMA data path and control interfaces.
21+
22+
Identifying the Adapter
23+
=======================
24+
25+
See Documentation/networking/device_drivers/ethernet/pensando/ionic.rst
26+
for more information on identifying the adapter.
27+
28+
Enabling the driver
29+
===================
30+
31+
The ionic_rdma driver depends on the ionic ethernet driver.
32+
See Documentation/networking/device_drivers/ethernet/pensando/ionic.rst
33+
for detailed information on enabling and configuring the ionic driver.
34+
35+
The ionic_rdma driver is enabled via the standard kernel configuration system,
36+
using the make command::
37+
38+
make oldconfig/menuconfig/etc.
39+
40+
The driver is located in the menu structure at:
41+
42+
-> Device Drivers
43+
-> InfiniBand support
44+
-> AMD Pensando DSC RDMA/RoCE Support
45+

48+

For general Linux RDMA support, please use the RDMA mailing
50+
list, which is monitored by AMD Pensando personnel::
