This repository contains the source code for the Async/Await post of the Writing an OS in Rust series.
Check out the master branch for more information.
This project requires a nightly version of Rust because it uses some unstable features. At least nightly 2020-07-15 is required for building. You might need to run rustup update nightly --force to update to the latest nightly even if some components such as rustfmt are missing it.
You can build the project by running:
cargo build
To create a bootable disk image from the compiled kernel, you need to install the bootimage tool:
cargo install bootimage
After installing, you can create the bootable disk image by running:
cargo bootimage
This creates a bootable disk image in the target/x86_64-blog_os/debug directory.
Please file an issue if you have any problems.
You can run the disk image in QEMU through:
cargo run
QEMU and the bootimage tool need to be installed for this.
You can also write the image to an USB stick for booting it on a real machine. On Linux, the command for this is:
dd if=target/x86_64-blog_os/debug/bootimage-blog_os.bin of=/dev/sdX && sync
Where sdX is the device name of your USB stick. Be careful to choose the correct device name, because everything on that device is overwritten.
To run the unit and integration tests, execute cargo xtest.
