I have your patchset building and running on an X-Gene based 8-core MP30AR0 system, passing traffic between two ports on and 82599 also. > Notes on arm64 kernel configuration: > > Tested on using Ubuntu 14.04 LTS with a 3.18 kernel and igb_uio. > ARM64 kernels does not have functional resource mapping of PCI memory > (PCI_MMAP), so the pci driver needs to be patched to enable this.

That fix looks almost exactly the same as the hack I did to my kernel :) I had a couple of small issues when patching/building: 1. Three of the files had an extra blank line at the end. Maybe worth running checkpatch on the patches. 'git am' was complaining. 2. I had problems compiling two drivers because they were attempting to include tmmintrin.h: ...dpdk/drivers/net/fm10k/fm10k_rxtx_vec.c:41:23: fatal error: tmmintrin.h: No such file or directory ...dpdk/drivers/net/i40e/i40e_rxtx_vec.c:43:23: fatal error: tmmintrin.h: No such file or directory To avoid this, I added the following two lines into defconfig_arm64-armv8a-linuxapp-gcc CONFIG_RTE_LIBRTE_FM10K_PMD=n CONFIG_RTE_LIBRTE_I40E_PMD=n and then it built fine, and I can run testpmd with my 82599's and run autotests. Thanks for that. Dave.
