Blockless WASI-v86 Extension

Blockless WASI-v86 Extension is an emulated v86 machine inside the Blockless Runtime Environment.

How to build.

1. Build wasm

install wasm-unknown-unknown target

$ rustup target add wasm32-unknown-unknown

use the follow command to generate the wasm file.

$ make release

2. Modify the config file.

The follow is the configure file

{
  "cdrom": "arch/linux4.iso",
  "bios_file": "arch/seabios.bin",
  "vga_bios_file": "arch/vgabios.bin",
  "wasm_file": "target/v86.wasm",
  "memory_size": 134217728,
  "vga_memory_size": 8388608,
  "cmdline": ["tsc=reliable mitigations=off random.trust_cpu=on"],
  "logger": {
    "log_file": "debug.log",
    "log_module": ["E", "BIOS", "NET"]
  },
  "tun": {
    "address": "192.168.0.1",
    "netmask": "255.255.255.0",
    "ether_address": "00:22:15:fe:ae:ba"
  },
  "muiltiboot_order": ["bin", "cdrom"]
}

3. Run the test linux

use the follow command to run the linux with the configure file.

$ cargo run -p v86-wasi --release ./boot.json

After run the VM, you can open the "term.html" file for control the VM.

4. DIY the linux iso

If you wanna DIY the linux by your self, please see the document "https://github.com/txlabs/v86-linux"

v86 Lib compilation

cargo build --release -p v86-lib

This will generate a libv86_lib.dylib file for your machine arch (which can be packaged in the car format to be run in the runtime)
