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 Linux Driver for the Pensando(R) Ethernet adapter family for more information on identifying the adapter.

Enabling the driver

The ionic_rdma driver depends on the ionic ethernet driver. See Linux Driver for the Pensando(R) Ethernet adapter family 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
