# XDP in userspace eBPF with DPDK
The repo is moved to https://github.com/userspace-xdp/userspace-xdp
## XDP examples: libbpf-bootstrap
Use libbpf-bootsrap to load xdp program in userspace.
### Run xdp-observer
Run in kernel
```console
make -C xdp-observer
# xdp-observer/main ens33

Test
```sh
```
## Compile and run
To get and build dpdk from the root project directory:
(Also add bpftime in the directory)
```sh
git submodule update --init --recursive
make dpdk
```
build bpftime library
```sh
export PKG_CONFIG_PATH=
cmake -B build-bpftime .
make -C build-bpftime
```
To build the dpdk-based server:
```sh
export PKG_CONFIG_PATH=
# e.g. export PKG_CONFIG_PATH=/home/yunwei37/XDP-eBPF-in-DPDK/external/dpdk/install-dir/lib/x86_64-linux-gnu/pkgconfig
make build
```
To run a very simple test:
In one terminal window
```sh
sudo ./build/base-server -l 0 --vdev=net_tap0,iface=tapdpdk
```
In another terminal window:
```sh
sudo ./scripts/testbed-setup.sh
sudo arping -i veth0 1.2.3.4
```
## clean up share memory
```sh
sudo build-bpftime/bpftime/tools/bpftimetool/bpftimetool remove
```
