It adds code into the same arm include directory, reducing code duplication. Tested on an XGene 64-bit arm server board, with PCI slots. Passes traffic between two physical ports on an Intel 82599 dual-port 10Gig NIC. Should work with many other NICS, but these are as yet untested. Compiles igb_uio, kni and all the physical device PMDs. An entry has been added to the Release notes. We hope that this will encourage the ARM community to contribute PMDs for their SoCs to DPDK. For now, we've added some Intel engineers to the MAINTAINERS file. We would like to encourage the ARM community to take over maintenance of this area in future, and to further improve it. Notes on arm64 kernel configuration: Using Ubuntu 14.04 LTS with a 4.3.0-rc6 kernel (with modified PCI drivers), and uio_pci_generic. ARM64 kernels do not seem to have functional resource mapping of PCI memory (PCI_MMAP), so the pci driver needs to be patched to enable this. The symptom of this is when /sys/bus/pci/devices/0000:0X:00.Y directory is missing the resource0...N files for mmapping the device memory. Earlier kernels (3.13.x) had these files present, but mmap'ping resulted in a "Bus Error" when the NIC memory was accessed. However, during limited testing with a modified 4.3.0-rc6 kernel, we were able to mmap the NIC memory, and pass traffic between the two ports on a 82599 NIC connected via fibre cable. We have no plans to upstream a kernel patch for this and hope that someone more familiar with the arm architecture can create a proper patch and enable this functionality.
