Pushing forward the Birth and Death of Javascript one step at a time.
tl;dr: To run this follow the Setup instructions then run make
. You'll almost certainly get errors that you'll have to
work through, because this was done in like 4 hours so set your expectations accordingly.
This is a small Rust project that produces a bootable binary with an embedded WebAssembly interpreter. It can boot in QEMU
using the included UEFI firmware (see ovmf
), then execute WebAssembly binaries. I haven't tried booting it on real hardware
but theoretically it should work as long as the machine has the right firmware.
It's basically what happens if you took uefi-rs
in one hand and
wasmi
in the other hand, and tried to stick them together. They had an enormous fight, and
when they were done WebAssembly was booting in QEMU.
That text comes from a Rust application in extern/init
that gets compiled to WebAssembly and embedded into the kernel binary then interpreted.
make setup
brew install qemu
At this point, running make
should start QEMU and show INFO: Hello from WASM!
as seen in the screenshot above.
