Hey. I've pushed a new expert example to the libriscv repository that represents where I've landed after years of using libriscv as a scripting API in my projects. It's the approach I use in my own game I'm working on, and it covers everything from generated function stubs to inter-VM RPC. If you've been looking at libriscv and wondering what a production setup looks like, this is how I'm personally using it.
Two papers from my doctorate work have been accepted and published at IEEE ACDSA 2026. I have uploaded the preprints.
This paper describes how TinyKVM makes per-request isolation usable for the first time by nearly matching native performance when serving requests from an unmodified Deno (latest version from webpage). We show that a complex React page rendering has better p90 and p99 in TinyKVM compared to native, and p50 is nearly equal, which we attribute to TinyKVM acting like a flat arena similar to those used in game engines.
This paper presents a method for remote execution between emulator instances by merging their address spaces. It enables one sandboxed program to make transparent function calls into another by sharing memory regions, avoiding serialization overhead while preserving isolation boundaries (in one direction). Clever tricks also enable ABI-compatible function arguments like passing C++ classes or Rust structs directly.
