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

[Felipe Huici <Felipe.Huici@xxxxxxxxx>]

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,

-- Felipe

    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

    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.
