rust-dpdk

Rust-Dpdk is a prototype to wrap DPDK API with Rust language.

Build

First, please follow the official document to setup a DPDK development envrionment.

+compiling problem solve: +before compiling dpdk: + +1?if on x86_64 platform:

export EXTRA_CFLAGS='-fPIC' #to generate relocaltion opcode

+2?asm patch: +illegal instructions "i" in rte_rtm.h:56 + +void rte_xabort(const unsigned int status) +{

-- asm volatile(".byte 0xc6,0xf8,%P0" :: "i" (status) : "memory");

```
++ asm volatile("": : : "memory");
```
```
++ _xabort(status);
```
```
++ asm volatile("": : : "memory");
```

+} + +3?change your cc command to clang-3.8

alias cc='/usr/bin/clang-3.8'
without this , _xabort is illegal in gcc

+after these configure ,you could compiling dpdk safety. +

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
