XunilOS
XunilOS is an OS made from scratch in Rust.
The repo is based on the limine-rust-template.
How to use this?
Dependencies
Any make command depends on GNU make (gmake) and is expected to be run using it. This usually means using make on most GNU/Linux distros, or gmake on other non-GNU systems.
All make all* targets depend on Rust.
Additionally, building an ISO with make all requires xorriso, and building a HDD/USB image with make all-hdd requires sgdisk (usually from gdisk or gptfdisk packages) and mtools.
Architectural targets
The KARCH make variable determines the target architecture to build the kernel and image for.
The default KARCH is x86_64. Other options include: aarch64, riscv64, and loongarch64.
Other architectures will need to be enabled in kernel/rust-toolchain.toml
Makefile targets
Running make all will compile the kernel (from the kernel/ directory) and then generate a bootable ISO image.
Running make all-hdd will compile the kernel and then generate a raw image suitable to be flashed onto a USB stick or hard drive/SSD.
Running make run will build the kernel and a bootable ISO (equivalent to make all) and then run it using qemu (if installed).
Running make run-hdd will build the kernel and a raw HDD image (equivalent to make all-hdd) and then run it using qemu (if installed).
The run-uefi and run-hdd-uefi targets are equivalent to their non -uefi counterparts except that they boot qemu using a UEFI-compatible firmware.
