README
Setting up DPDK
===============
Install dependencies
```
apt-get update
apt-get install meson
```
Compile DPDK
```
cd dpdk
meson build
cd build
ninja
ninja install
ldconfig
```
Load the `vfio-pci` driver :
```
modprobe uio
modprobe uio_pci_generic
```
Use the tool `dpdk-devbind.py` to bind the VirtIO NICs to the `uio_pci_generic` driver.
(Find out how to do this, the tool is self-explanatory.)
```
cd [root_repo]
dpdk/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
```
Compiling your App
==================
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
```
cd [root_repo]
cmake .
make
```
That's all!
DPDK Reference
==============
For this project, we use DPDK 20.11 (LTS).
The comprehensive DPDK documentation can be found at:
* [HTML guides](https://doc.dpdk.org/guides-20.11/)
* [HTML API](https://doc.dpdk.org/api-20.11/)
Compiling gtest
===============
Installing/Compiling gtest is no longer necessary, VM contains compiled library.
Remark on ACN-VM
================
add `recv_from_device()` utility function
The virtual switch behaves different from real hardware.
It sets rx = tx queues with automatic load balancing (even when not configured).
The `recv_from_device()` function fixes this issue by receiving from all available queues.
