Introduction ============ OpenOnload(R) is a high performance user-level network stack, which delivers absolutely the best performance to applications using the BSD sockets API. Please see www.openonload.org for more information. EnterpriseOnload is a version of OpenOnload that includes an extended test cycle, guaranteed support from Solarflare, bug fixes and a defined service level agreement. OpenOnload and EnterpriseOnload are licensed under the GNU General Public License (Version 2, June 1991). See the LICENSE file in this distribution for details. Supported platforms =================== Linux kernels from 3.10. The following processor architectures are supported: - amd64/em64t (support for AMD processors prior to Zen is deprecated) - ia32 (in userspace for Onloaded applications only) - aarch64 (to preview level) Onload supports Solarflare SFC9000 network controller chips, including the following network adapters: X2541, X2542 X2522, X2522-25G SFN8042 SFN8522, SFN8522M, SFN8542, SFN8722 SFN7142Q SFN7122F, SFN7322F, SFN7124F Onload support for the following network adapters is deprecated: SFN5122F, SFN5322F SFN6122F, SFN6322F SFN5812H, SFN5814H SFN5802K SFN5121T If you are interested in trying or buying Solarflare network adapters, please contact <sales@solarflare.com>. Documentation ============= The Onload User Guide is available to customers with supported cards. You can register and download a copy from: https://support.solarflare.com/. You may also find the Server Adapter User Guide useful -- it is available from the same place. Quick start =========== If deploying Onload from a tarball, then the following command will build and install the Onload drivers into system directories (as root). For instructions on other Onload installation packages (e.g. source RPM), please refer to the Onload user guide. <top>/scripts/onload_install You may need to reload the drivers if you have drivers loaded already: onload_tool reload Or to load the Onload and sfc drivers if none are loaded: modprobe sfc You may need to configure your ethernet interface with an IP address using the standard tools. Please see the documentation that comes with your Linux distribution for details. To accelerate an application with the Onload user-level transport, simply invoke the application on the command line as normal, prepended with "onload". ie. Instead of: netperf -t TCP_RR -H myserver do this: onload netperf -t TCP_RR -H myserver and tuned for best latency: onload -p latency netperf -t TCP_RR -H myserver Configuration and tuning ======================== Onload takes many configuration settings directly from the kernel stack. In addition, there are a number of configuration and tuning options that can be set via environment variables. See the Onload User Guide for details. You can get detailed descriptions of the configuration options in the version of Onload that you are using by running the following command: onload_stackdump doc Any questions? ============== Website: www.openonload.org For support please go to https://support.solarflare.com or email <support@solarflare.com>. ========== version: onload-7.1.0.265 revision: bd4c2f69606ebe414a12c363d430e1c42e437464 date: Tue 5 May 10:27:27 BST 2020
