[dpdk-dev] KNI interface is not coming up

Hi, I am testing DPDK 2.0 release. I am not able to bring the KNI interface up. It always gives the following error. SIOCSIFFLAGS: Timer expired This is on Ubuntu, Linux vthummala-PowerEdge-R720 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Hi, I have built a DPDK application [based on version 2.0] and run on the native machine successfully. I have tried running the binary on a different machine, but it resulted in a CRASH with the following back trace. Please find the CPU info of the machines from the attachment. cpuinfo-1 -

[dpdk-dev] sharing rte_malloc() address between processes.

Hi, Yo ? The multi-process feature requires that the exact same hugepage memory mappings be present in all applications. The Linux security feature - Address-Space Layout Randomization (ASLR) can interfere with this mapping, so it may be necessary to disable this feature in order to reliably run

[dpdk-dev] using hash table in a MP environment

Hi Shirley, Please refer the section 20.3 [Multi-Process Limitations] in DPDK Programmers Guide. The use of function pointers between multiple processes running based of different compiled binaries is not supported, since the location of a given function in one process may be different to its

[dpdk-dev] L2 FWD / L3 FWD performance with Rx and Tx ports on different sockets

Hi, I guess, the current L2 FWD / L3 FWD performance numbers are observed with both Rx and Tx ports connected to the same Socket. Does anyone have the performance numbers with Rx and Tx ports on two different sockets? How does DDIO come in to picture in this case? I believe DDIO comes in to
