Show HN: Munal OS: a graphical experimental OS with WASM sandboxing
An experimental operating system fully written in Rust, with a unikernel design, cooperative scheduling and a security model based on WASM sandboxing. - Askannz/munal-os
The reliance on VirtIO means Munal OS does not support running on real hardware yet; more work would be needed, either to use BIOS/UEFI-provided methods (such as PS/2, VGA, GOP) or to implement full-blown GPU and USB drivers. Uitk is an immediate mode toolkit which supports some basic widgets: buttons, progress bars, text editing, scrollable canvas...a generic triangle rasterizer is also provided (which is used to draw the radial pie menu and the 3D cube demo), A basic caching system is implemented to avoid unnecessary redraws: for example, generic scrollable canvases (like the web browser) are split into "tiles" tracked with a unique content ID.
