I've pasted the replies: --------------------------------------------------------------------------------------------------------------------------- I see thanks. I'm actually running my DPDK application on a guest OS but I'm always getting an invalid instruction error. I was thinking that this was due to ixgbevf driver in guest that commands the host driver which is not-fully supported by DPDK, and consequently ran an invalid instruction. This brings me back to the questions: Are SR-IOV virtual function drivers supported by DPDK PMD (I guess yes) ? If yes, does the physical function (host) driver affects the DPDK application in any way especially if it isn't fully supported yet by DPDK? I've tried looking at incompatibility issues with respect to compiler and processor archs. but it seems OK to me. Thanks, Pepe ---------------------------------------------------------------------------------------------------------------------------- SR-IOV is supported. There are dependencies with PF driver which handle NIC configuration. VF/PF communication is done via mailbox. Please use the list.
