[dpdk-users] DPDK i40evf problem in receving packet
Hi, I'm seeing two problems: 1) when use our kernel '3.10.88-8.0.0.0.6', we only receive first packet but not subsequent ones at all after that. However, when I use centos7.0, then l2fwd is able to receive all the packets. 2) I've also seen that on centos7.0, symmetric_mp itself is not working. dev start fails with 280 error. i40evf is giving us lot of headache. The i40evf kernel driver works without any problem. Host is a centos7 KVM. I've already upgraded firmware to latest.

Some details about hugepages here: http://dpdk.org/doc/guides/linux_gsg/build_sample_apps.html#hugepage-memory-use-by-applications To solve it, the easiest way is to use the "tools/setup.sh" script: cd /path/to/dpdk ./tools/setup.sh # Read the options, select "Set up hugepages" Say how many hugepages to use, I use 512 when not doing performance testing. Note that this must be performed after each reboot. Hope that helps, -Harry

Take a look at the Getting Started Guide (section 2.3.2): http://dpdk.readthedocs.org/en/v2.2.0/linux_gsg/sys_reqs.html#running-dpdk-applications Another way is run the setup.sh script, in tools directory. Options 20 and 21 will do the hugepage reserve for you, just need to pass the number of hugepages that you want. Let me know if you have any more issues. Pablo > > >
