Testing rdma-core userspace tools
|
||||
=================================
|
||||
|
||||
Testing rdma-core using Linux software RoCE implementation:
|
||||
https://en.wikipedia.org/wiki/RDMA_over_Converged_Ethernet
|
||||
|
||||
Using two systems with working TCP/IP configuration, for example:
|
||||
- Server IP: 192.168.123.10
|
||||
- Client IP: 192.168.123.20
|
||||
|
||||
Make sure firewall configurations are appropriate. Routable RoCE v2
|
||||
uses udp/4791. ibv_rc_pingpong uses tcp/18515 for initial
|
||||
synchronization.
|
||||
|
||||
Note: this test can be executed in two qemu virtual machines with
|
||||
bridged networking.
|
||||
|
||||
|
||||
Kernel configuration
|
||||
--------------------
|
||||
|
||||
The Linux Kernel needs some InfiniBand configuration. In this example
|
||||
the kernel "rdma_rxe" driver is needed (CONFIG_RDMA_RXE=y). The Kernel
|
||||
config fragment file used for package test can be used as a starting
|
||||
point. See:
|
||||
|
||||
support/testing/tests/package/test_rdma_core/linux-rdma.fragment
|
||||
|
||||
|
||||
Buildroot package configuration
|
||||
-------------------------------
|
||||
|
||||
For setting up a software RoCE link, the "rdma" program is needed. It
|
||||
is provided by the "iproute2" package, when "libmnl" is also
|
||||
selected. Make sure to have in your Buildroot configuration:
|
||||
|
||||
BR2_PACKAGE_IPROUTE2=y
|
||||
BR2_PACKAGE_LIBMNL=y
|
||||
BR2_PACKAGE_RDMA_CORE=y
|
||||
|
||||
|
||||
Setting up the rdma link
|
||||
------------------------
|
||||
|
||||
On both server and client:
|
||||
|
||||
modprobe rdma_rxe
|
||||
rdma link add rxe0 type rxe netdev eth0
|
||||
|
||||
|
||||
Testing with rping
|
||||
------------------
|
||||
|
||||
On the server side, run the command:
|
||||
|
||||
rping -s -v
|
||||
|
||||
On the client side, run the command:
|
||||
|
||||
rping -c -v -a 192.168.123.10
|
||||
|
||||
|
||||
Testing with ibv_rc_pingpong
|
||||
----------------------------
|
||||
|
||||
To test with the pingpong example using the reliable connected (RC)
|
||||
transport:
|
||||
|
||||
On the server side, run the command:
|
||||
|
||||
ibv_rc_pingpong -d rxe0 -g 1
|
||||
|
||||
On the client side, run the command:
|
||||
|
||||
ibv_rc_pingpong -d rxe0 -g 1 192.168.123.10
