rust-dpdk
Rust-Dpdk is an experimental prototype to wrap DPDK API with Rust language.
Build
First, please follow the official document to setup a DPDK development envrionment.
$ CONFIG_RTE_BUILD_COMBINE_LIBS=y EXTRA_CFLAGS="-fPIC -O0 -g -ggdb" make install T=x86_64-native-linuxapp-gcc -j 4
And build rust-dpdk with RTE_SDK envrionment variable:
$ RTE_SDK=<rte_path> cargo build
Examples
extern crate rte;
use std::env;
use std::ptr;
use std::os::raw::c_void;
use rte::*;
extern "C" fn lcore_hello(_: *const c_void) -> i32 {
println!("hello from core {}", lcore::id().unwrap());
0
}
fn main() {
let args: Vec<String> = env::args().collect();
eal::init(&args).expect("Cannot init EAL");
// call lcore_hello() on every slave lcore
lcore::foreach_slave(|lcore_id| {
launch::remote_launch(lcore_hello, None, lcore_id).expect("Cannot launch task");
});
// call it on master lcore too
lcore_hello(ptr::null());
launch::mp_wait_lcore();
}Please check l2fwd example for details.
$ sudo RTE_SDK=<rte_path> cargo run --example l2fwd -- --log-level 8 -v -c f -- -p f
