[dpdk-dev] Question on VMDq mode

Hi, last week I sent a question about VMDq and I did not get any reply. Today I'll be more generic rather than last time, and I hope someone will clarify my ideas. Through the DPDK framework, is it possible to make a pre-filter based on some header parameter directly on the NIC (in addition to t

[dpdk-dev] Issues on FDIR and multi-processes

Hi everyone, we are working with Flow DIRector on a multiprocess application. This application consists of N secondary processes, each one receiving packets directly from its own queue on the NIC. It works fine when each secondary process runs on a different CPU core; instead, if we try to run t

[dpdk-dev] Is Flow Director supported on the x540 chipset?

Hi, I'm trying to use Flow Director. Initially I used a X540 chipset and I was not able to make it work; I thought it was a compatibility problem with the controller. Maxime suggested to change some lines in the ixgbe_fdir.c file, I changed these lines but it did not give the expected resu

[dpdk-dev] Question on DPDK multi-process support

Hi, I have some doubts on the DPDK multi-process support: 1) According to the Programmers Guide (pag. 109 - 20.3 Multi-process Limitations), one of the multi-process limitations is: "All Intel? DPDK processes running as a single application and using shared memory must have distinct coremask ar

[dpdk-dev] Question on DPDK multi-process support

Hi Bruce, just for dispel any doubt: if there is one primary process and N secondary processes, and each process uses only one logical core (they have a coremask equal to 0x01, 0x02, 0x04, ), I can run at the same time at most "my CPU logical cores - 1" secondary processes. Is it right?
