terminus

A RISC-V instruction set simulator in Rust.

Rust Version Requirement

>= 1.56(edition2021)

2018 edition is move to 'eidtion2018' branch

Boot Linux in 20s

Getting Started

  git clone https://github.com/shady831213/terminus
  cd terminus
  cargo update -p terminus-spaceport
  cargo update -p terminus-vault
  cargo install --path .
  terminus examples/linux/image/br-5-4
  //or
  cd examples/linux/image
  tar -zxvf rootfs.ext4.gz
  cd -
  terminus examples/linux/image/br-5-4.disk --image=examples/linux/image/rootfs.ext4

Multi-core Support

Specify the -p option to configure the number of RISC-V HARTs (HARdware Threads):

  terminus examples/linux/image/br-5-4 -p 4
  //booting...
  //booting...
  //booting...
  //...
  buildroot login: root
  //password is terminus
  Password:
  # cat /proc/cpuinfo

  processor	: 0
  hart		: 0
  mmu		: sv48

  processor	: 1
  hart		: 1
  mmu		: sv48

  processor	: 2
  hart		: 2
  mmu		: sv48

  processor	: 3
  hart		: 3
  mmu		: sv48

Networking Support

Run the setup_tuntap.sh script to create a simulated network interface and networking bridge.

  terminus examples/linux/image/br-5-4.disk --image=examples/linux/image/rootfs.ext4 --net=tap0
  //booting...
  //booting...
  //booting...
  //...
  buildroot login: root
  //password is terminus
  Password:
  //config guset according to help message.
  # ping -c 1 www.baidu.com

then you will see:

PING www.baidu.com (103.235.47.103): 56 data bytes
64 bytes from 103.235.47.103: seq=0 ttl=46 time=17.685 ms

--- www.baidu.com ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 17.685/17.685/17.685 ms

Display Support

Terminus with display supported needs the "sdl" operating system packages and related dependencies.

  // Example for  Ubuntu
  sudo apt-get install libsdl2-dev
  git clone https://github.com/shady831213/terminus
  cd terminus
  cargo update -p terminus-spaceport
  cargo install --features="sdl" --path .

  cd examples/linux/image
  tar -zxvf rootfs.ext4.gz
  cd -
  terminus examples/linux/image/br-5-4.disk --image=examples/linux/image/rootfs.ext4 --boot_args="root=/dev/vda console=tty0 earlycon=sbi" --display
