E1000 Driver

E1000 driver in Rust for the Intel 82540EP/EM and 82574L Gigabit Ethernet.

Support features

  • e1000 and e1000e driver on Qemu and a Physical Industrial Computer are supported
  • Initialize simple PCI-Express for e1000 device
  • Implement the e1000 driver as a linux driver module
  • Todo: networking protocol support: IP, ARP, UDP

Quick start on bare metal OS

For instance, E1000 driver in Rust on ArceOS/Starry

e1000 on arceos

Initialize PCI and E1000 driver

pub struct Kernfn;
impl e1000_driver::e1000::KernelFunc for Kernfn { ... }

e1000_driver::pci::pci_init();

let mut e1000_device = e1000_driver::e1000::E1000Device::<Kernfn>::new(e1000_driver::pci::E1000_REGS as usize).unwrap();

Sending network packets

e1000_device.e1000_transmit(&frame);

Receiving network packets

let rx_buf = e1000_device.e1000_recv();

Rust e1000 driver for Linux kernel module
