Thanks, I was able to complete the getting started tutorial. Where can I find the material for porting runtimes? I'm not optimistic I can contribute but worth taking a look!

Hi Jonathan,

I think targeting wasm-micro-runtime would make sense, and the porting process isn't as difficult as it sounds :). Do you know if wasm-micro-runtime's build system is able to generate a static library/archive? We could then link that into a Unikraft build. In terms of languages, right now we support c/c++, so that would work for wasm-micro-runtime (we're working on other languages such as Go, Rust, Python, Ruby, etc.). We also support pthreads...and as far as I can tell the only dependency that wasm-micro-runtime has is glibc (which we can replace with newlib, which we support; we're working on musl too).

If you're interested, perhaps you can take just a bit of time to do a short Unikraft tutorial? https://wiki.xenproject.org/wiki/Category:Unikraft_Tutorial

We also have a bit of material on how porting to Unikraft works, again, noting too time consuming.

Thanks,

Great to hear! Unfortunately porting is beyond my skills but I'd love to help where I can! Fortunately, there are several implementations of Wasm runtimes that have a comptabible license. Are there any technical requirements that would need to
be satisfied, like language or threading model?

Hey Jonathan,

thanks for reaching out to us. We agree, WASM is another very interesting target and we had already internal discussions about porting this. You are right with
your arguments.

So far, no one is working on this. Would you like to do a port of WASM to Unikraft? We could give some starting pointers.
An important criteria for selecting the runtime is the open source license that is used and if it is compatible to our Unikraft BSD license. For instance, projects
using GPL ones would not work for us.

Let us know what you think.

Thanks,

Simon

Subject: [Minios-devel] WebAssembly Runtime for Unikraft?

I'm new to Unikraft but as I understand it, new language support is added by adding new runtimes. Has the team evaluated using WebAssembly (https://webassembly.org/)
as a runtime? WASM by design is meant to execute any language that can compile to it and by design isn't limited to the web (see https://webassembly.org/docs/non-web/.) There are many runtime
implementations which could be used (https://github.com/appcypher/awesome-wasm-runtimes) and are running on everything from serverless compute platforms (https://www.cloudflare.com/products/cloudflare-workers/)
to microcontrollers (https://github.com/intel/wasm-micro-runtime.) Adopting a WebAssembly runtime could open up Unikraft to many more languages, which means potential for code reuse.
