vpp-lite
- A build without DPDK suitable for container deployment
- vpp-dev email thread
export PLATFORM=vpp_lite make build make run
arm aarch32
- build configuration inherited from vpp-lite
- 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
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
- Finally, run as usual:
make run
