An x86 kernel written in Zig
Pluto is a kernel written almost entirely in Zig and supports x86, with aarch64 and x64 backends being planned.
All of these goals will benefit from the features of Zig.
Requires a master build of Zig (downloaded or built from source) xorriso and the grub tools (such as grub-mkrescue). A qemu-system binary compatible with your chosen target is required to run the kernel (e.g. qemu-system-i386).
zig build run
or if you want to wait for a gdb connection:
zig build debug-run
Launch a gdb-multiarch instance and connect to qemu.
zig build debug
Run the unit tests.
zig build test
Run the runtime tests.
zig build rt-test -Dtest-mode=
Available test modes:
None: This is the default, this will run the OS normally.
Initialisation: Run the OS's initialisation runtime tests to ensure the OS is properly set up.
Panic: Run the panic runtime test.
-D[build-mode]=: Boolean (default
-Dtarget=: String (default
i386-freestanding). The standard target options for building with zig. Currently supported targets:
-Ddisable-display: Boolean (default
