terminus

A RISC-V instruction set simulator in Rust.

Rust Version Requirement

  1. >= 1.56(edition2021)

2018 edition is move to ‘eidtion2018’ branch

Boot Linux in 20s

Boot Linux in 20s

Getting Started

  1.   git clone https://github.com/shady831213/terminus
  2.   cd terminus
  3.   cargo update -p terminus-spaceport
  4.   cargo update -p terminus-vault
  5.   cargo install --path .
  6.   terminus examples/linux/image/br-5-4
  7.   //or
  8.   cd examples/linux/image
  9.   tar -zxvf rootfs.ext4.gz
  10.   cd -
  11.   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):

  1.   terminus examples/linux/image/br-5-4 -p 4
  2.   //booting...
  3.   //booting...
  4.   //booting...
  5.   //...
  6.   buildroot login: root
  7.   //password is terminus
  8.   Password:
  9.   # cat /proc/cpuinfo
  11.   processor    : 0
  12.   hart        : 0
  13.   mmu        : sv48
  15.   processor    : 1
  16.   hart        : 1
  17.   mmu        : sv48
  19.   processor    : 2
  20.   hart        : 2
  21.   mmu        : sv48
  23.   processor    : 3
  24.   hart        : 3
  25.   mmu        : sv48

Networking Support

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

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

then you will see:

  1. PING www.baidu.com (103.235.47.103): 56 data bytes
  2. 64 bytes from 103.235.47.103: seq=0 ttl=46 time=17.685 ms
  4. --- www.baidu.com ping statistics ---
  5. 1 packets transmitted, 1 packets received, 0% packet loss
  6. 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.

  1.   // Example for  Ubuntu
  2.   sudo apt-get install libsdl2-dev
  3.   git clone https://github.com/shady831213/terminus
  4.   cd terminus
  5.   cargo update -p terminus-spaceport
  6.   cargo install --features="sdl" --path .
  8.   cd examples/linux/image
  9.   tar -zxvf rootfs.ext4.gz
  10.   cd -
  11.   terminus examples/linux/image/br-5-4.disk --image=examples/linux/image/rootfs.ext4 --boot_args="root=/dev/vda console=tty0 earlycon=sbi" --display
