vpp-lite

• A build without DPDK suitable for container deployment
• vpp-dev email thread

export PLATFORM=vpp_lite
make build
make run

arm aarch32

* Raspberry Pi

• vpp-dev email thread

• make install-dep fails as the OS is not recognized, so install dependencies manually:

apt-get install curl build-essential autoconf automake bison libssl-dev ccache \
debhelper dkms openjdk-8-jdk git libtool libganglia1-dev libapr1-dev dh-systemd \
libconfuse-dev git-review exuberant-ctags cscope

• Build:

export PLATFORM=arm32
make build

• raspbian default kernel does not enable userspace application access to the performance counters (this access is required by vpp to read the cycle counter)
  • Download kernel module from github
  • This requires kernel headers: if you updated your kernel with rpi-update, you may have to download the whole kernel sources to retrieve kernel headers (see rpi-source)
  • build and test kmod (see included README)

• raspbian kernel does not have hugepage support: modify the startup.conf file to specify the amount of RAM to allocate

cpu {
  main-core 1
}
heapsize 64M

* Tegra - Jetson TK1 As Linux 4 Tegra is recognized as Ubuntu, we can just build as usual. On Tegra, we may use DPDK, but we have to rebuild our own kernel (tested with 4.5.3) to enable hugepages. Also, we must disable cpu idle.

#!/bin/sh
for cpu in 0 1 2 3 ; do
for state in 0 1 ; do
echo 1 > /sys/devices/system/cpu/cpu$cpu/cpuidle/state$state/disable
done
done
