[dpdk-dev] New to DPDK

Most people I guess use a Xeon CPU class MB with one or two sockets running Linux with a supported NICs. I use a motherboard like the one below running Ubuntu 12.04 with 12G RAM and the 82599 NICs. You can find more supported NICs in the documentation and you need find the rest of the parts :-) You

Yes, the DPDK reports port is UP. By the following change in the registered callback function to comment out stop/start the dpdk interface, I can bring the KNI vEthX interfaces up: (I guess, the reason is the ret value is now the default ret = 0, and no error from stop/start. ) kni_config_network_

[dpdk-dev] Fast Path Query

Hi Helin, If we use exception_path or KNI, which extracts packet from Linux kernel (for DPDK application processing), will it still remain fast path? Will it not impact the performance; as Linux interrupt framework shall also come into picture here? On Wed, Jan 14, 2015 at 1:17 PM, Zhang, Helin

Ok, so 1.8.0 came out almost a month ago and none of the patches that were deferred waiting for the release got merged since then. Last commit in git is the 1.8.0 release. Where is the post-merge window bundle, where are the later commits? Lots of patches are sitting rotting in patchwork...

[dpdk-dev] Fast Path Query

Your application (which you build on top of DPDK) needs to filter which traffic is control traffic and inject it into the network stack. You can leverage DPDK KNI for that ( http://dpdk.org/doc/guides/prog_guide/kernel_nic_interface.html) Keep in mind you also need to take care of the TX side. On

Hi Deepak Exception path or KNI just provide an exceptional path for packet exchanging between user space and kernel space. All packet IO are still in user space DPDK, Linux kernel still doesn?t know the NIC port. So, no standard Linux interrupt. Regards, Helin From: Deepak Sehrawat [mailto:d

[dpdk-dev] Fast Path Query

Hi Deepak If a NIC port is controlled by DPDK, all packets received by that port will go directly to DPDK, and Linux kernel doesn't know those packets anymore. But, the packets received by DPDK can be put into kernel by two special ways. They are exception_path and KNI. Please check the examples
