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

Hi,

can you please give a few more details about your setup? What version of the Intel DPDK are you using? I tried using the command you give below on my system with 82599-based NICs and testpmd starts up without any issues.

Here's the (clipped for brevity) output that I get:

$ sudo ./testpmd -c 0x0f -n 2 -m 512 -- -i --portmask=0x3 --nb-cores=2 --pkt-filter-mode=perfect --rxq=2 --txq=2
EAL: No free hugepages reported in hugepages-2048kB

Perhaps you could also try turning on some of the IXGBE debug options in your compile time config e.g. defconfig_x86_64-default-linuxapp-gcc. Setting "CONFIG_RTE_LIBRTE_IXGBE_DEBUG_INIT" and "CONFIG_RTE_LIBRTE_IXGBE_DEBUG_DRIVER" to "y" might provide some useful output.
