CONFIG_SUNRPC_XPRT_RDMA: RPC-over-RDMA transport

General informations

The Linux kernel configuration item CONFIG_SUNRPC_XPRT_RDMA has multiple definitions:

RPC-over-RDMA transport found in net/sunrpc/Kconfig

The configuration item CONFIG_SUNRPC_XPRT_RDMA:

• prompt: RPC-over-RDMA transport
• type: tristate
• depends on: CONFIG_SUNRPC && CONFIG_INFINIBAND && CONFIG_INFINIBAND_ADDR_TRANS
• defined in net/sunrpc/Kconfig
• found in Linux kernels: 4.2–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD
• modules built: rpcrdma, svcrdma, svcrdma, xprtrdma

Help text

This option allows the NFS client and server to use RDMA transports (InfiniBand, iWARP, or RoCE).

To compile this support as a module, choose M. The module will be called rpcrdma.ko.

If unsure, or you know there is no RDMA capability on your hardware platform, say N.

found in net/sunrpc/Kconfig

The configuration item CONFIG_SUNRPC_XPRT_RDMA:

• prompt:
• type: tristate
• depends on: CONFIG_SUNRPC && CONFIG_INFINIBAND && CONFIG_INFINIBAND_ADDR_TRANS
• defined in net/sunrpc/Kconfig
• found in Linux kernels: 2.6.29–2.6.39, 3.0–3.14
• modules built: rpcrdma, svcrdma, svcrdma, xprtrdma

Help text

This option allows the NFS client and server to support an RDMA-enabled transport.

To compile RPC client RDMA transport support as a module, choose M here: the module will be called xprtrdma.

If unsure, say N.

found in fs/Kconfig

The configuration item CONFIG_SUNRPC_XPRT_RDMA:

• prompt:
• type: tristate
• depends on: CONFIG_SUNRPC && CONFIG_INFINIBAND && CONFIG_EXPERIMENTAL
• defined in fs/Kconfig
• found in Linux kernels: 2.6.25–2.6.28
• modules built: rpcrdma, svcrdma, svcrdma, xprtrdma

Help text

This option enables an RPC client transport capability that allows the NFS client to mount servers via an RDMA-enabled transport.

To compile RPC client RDMA transport support as a module, choose M here: the module will be called xprtrdma.

If unsure, say N.

RDMA transport for sunrpc (EXPERIMENTAL) found in fs/Kconfig

The configuration item CONFIG_SUNRPC_XPRT_RDMA:

• prompt: RDMA transport for sunrpc (EXPERIMENTAL)
• type: tristate
• depends on: CONFIG_SUNRPC && CONFIG_INFINIBAND && CONFIG_EXPERIMENTAL
• defined in fs/Kconfig
• found in Linux kernels: 2.6.24
• modules built: rpcrdma, svcrdma, svcrdma, xprtrdma

Help text

Adds a client RPC transport for supporting kernel NFS over RDMA mounts, including Infiniband and iWARP. Experimental.
