[dpdk-dev] Synchronize DPDK NICs using IEEE 1588 Precision Time Protocol (PTP)

Hi all, I have a DPDK app that requires tight time synchronization between end hosts. In my setup, the testbed is connected to a Cisco switch that supports the PTP protocol. I know that the ixgbe driver for Intel 82599 nics support the PTP time protocol, but I'm not sure if the DPDK framework supp

[dpdk-dev] rte_pmd_init_all() with DPDK 1.7.0

Hi all I have a very basic DPDK app that runs in two modes: sender and sniffer. In the sender mode, the app just reads data from a shared memory buffer and sends packets out on a port using rte_eth_tx_burst. In the sniffer mode, the app polls for incoming packets on a port using rte_eth_rx_burst

Hi I am trying to run the testpmd app as but I get the following errors: EAL: VFIO could not be initialized EAL: Cannot open /dev/uio0: No such file or directory EAL: Error - exiting with code: 1 Cause: Requested device :07:00.0 cannot be used lsmod shows that the uio module is installed. I

[dpdk-dev] LD_PRELOAD libraries for DPDK to run unmodified applications with DPDK?

Hi all, I've been trying to run unmodified applications with the DPDK framework. I used the KNI module and while it allowed me to run stock applications with DPDK infrastructure, it was not optimized for performance. There is already a rump-kernel based TCP/IP stack for DPDK https://github.com/r

[dpdk-dev] Maximum possible throughput with the KNI DPDK Application

Hi all I've been playing the with DPDK API to send out packets using the l2fwd app and the Kernel Network Interface app with a single Intel 82599 NIC on an Intel Xeon E5-2630 With the l2fwd application, I've been able to achieve 14.88 Mpps with minimum sized packets. However, running iperf with t
