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:: + + linux-rdma@vger.kernel.org |
