hk - an operating system kernel written in Rust

Design goals

Modern multi-processing

Multi-threaded, multi-core: Designed for modern 64-bit multi-core processors.

Initially targeting x86-64 and aarch64.

Device tree

The kernel uses a device tree to describe the hardware components of the system. This allows for a flexible and extensible way to manage hardware resources.

Linux compatible

Uses the Linux syscall ABI for each respective architecture.

Wishlist

• io_uring model for syscalls and ioctls
• hybrid kernel/user model for DMA'ing device drivers
• eBPF even more widely used
• Policy cut-off for legacy hardware: Require >= 2021 ? Open to debate.

Building etc

Run make check or make check-arm. Run make help for more info.

Requires qemu, dosfstools, and iso tools.
