Qor

Basic kernel written in Rust for RISC-V, initially following the tutorial by Stephen Marz RISC-V OS using Rust.

Stored in seperate repositories are the libc implementation and the userland programs

Install

1. Clone the repository and all submodules
2. Navigate to the qemu directory
3. Create a new directory called build and navigate there
4. Run ../configure --target-list=riscv64-softmmu --enable-sdl && make
5. Install qemu to your path
6. Navigate to the qor-os directory
7. Run rustup override set nightly to set the Rust compiler version
8. Run rustup target add riscv64gc-unknown-none-elf to install the proper target
9. Run rustup component add rust-src to allow the core library to be built

First Time Execution

Before the first execution, the hard disk must be created using the following in the qor-os directory:

fallocate -l 32M hdd.dsk
sudo losetup /dev/loop11 hdd.dsk
sudo mkfs.minix -3 /dev/loop11
sudo losetup -d /dev/loop11

The userland programs must also be built before the first execution, to do so run ./build.py rebuild in the root directory.

Usage

To start the kernel, run ./build.py run in the root directory.
