DPDK apps are now working on CentOS 6.4
This is an update to my last email requesting help with the DPDK sources and Fedora 14.
After talking with a colleague who was investigating DPDK as well, I removed the Fedora 14 install and installed instead CentOS 6.4. After installing the release, I did a 'yum update' on the kernel sources to obtain their latest kernel (2.6.32 + patches) which seems to include the hugepage fixes pointed out in the "Getting Started" guide. Plus, HPET was fully there (it was not mmapable in F14 until I rebuilt the kernel).
Booted with hugepages=1024, mounted /mnt/huge, 'make config' and 'make', installed uio and igb_uio and ran build/app/testpmd as shown on the website and now packets are moving. I don't know (yet) why Fedora 14 would not work while CentOS does when it looks like they have the same fixes. I partitioned my drive when I installed CentOS so I could install Fedora 14 back on the box as well.
The only error I was the inability to mmap the HPET even though the kernel config shows HPET_MMAP=y.
Later,
Patrick

It's strange. I've already seen DPDK running on Fedora 14.

You should try with the option --no-hpet.
