Support changing 9p mount tag at runtime

[hello-smile6]

It would be helpful to be able to change the name of the 9p file share. https://github.com/copy/v86/blob/4eb1e5035e91490c5aeebab45553d5043cd84b95/lib/9p.js#L82

For dynamically generating mount tags:

/**
 * @param {string} mountTagName
 */
function genMountTagArray(mountTagName) {
    /**
     * @type {Number[]}
     */
    let _mountTagArray;
    Array.from(mountTagName).forEach(function(char) {
        _mountTagArray.push(char.charCodeAt(0));
    });
    return _mountTagArray;
};

PR would be welcome.

Don't know how to implement it, how can data be passed to lib/9p.js?

I am going to try and implement this

Is there a way to compile v86 without rustup?

Use https://shell.cloud.google.com/ .

Shouldn't need the WebAssembly to be compiled, try downloading v86.wasm from copy.sh or a release. As long as you don't touch Rust, it'd probably be backwards-compatible.

Use make build/*.js

In cpu.js code:

if(settings.fs9p)
{
     this.devices.virtio_9p = new Virtio9p(settings.fs9p, this, device_bus);
}

So, you can access to Virtio9p class with:

emulator.v86.cpu.devices.virtio_9p
