Compile DPDK cd dpdk make config T=x86_64-native-linuxapp-gcc make T=x86_64-native-linuxapp-gcc
Load the igb_uio driver and its dependency uio
modprobe uio
insmod build/kmod/igb_uio.ko
Use the tool dpdk-devbind.py to bind the VirtIO NICs to the igb_uio driver.
(Find out how to do this, the tool is pretty self-explanatory.)
usertools/dpdk-devbind.py --h
Setup hugetlbfs huge pages for DPDK mkdir /mnt/huge mount -t hugetlbfs nodev /mnt/huge Statically allocate 256 2MB huge pages echo 256 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
This example project comes with a CMakeFile and a simple wrapper that initializes DPDK for you. Run the following steps to build the router app cmake . make
That's all!
Compiling the gtest library is required to execute table-test
Fetching gtest apt-get install libgtest-dev
Compiling gtest cd /usr/src/googletest/googletest cmake . make make install
add recv_from_device() utility function
Apparently our virtual switch works different from last year and sets rx = tx queues with automatic load balancing (even when not configured) so this is a simple work-around.
