The Node Replicated Kernel is an (experimental) research OS kernel for x86-64 (amd64) machines written in rust. You can read more about it here.

1. git clone <repo-url> nrk
2. cd nrk
3. Note: In case you don't have the SSH key of your machine registered with a github account, you need to convert the submodule URLs to the https protocol, to do so run: sed -i'' -e 's/[email protected]:/https:\/\/github.com\//' .gitmodules
4. git submodule update --init

Run bash setup.sh, this will install required dependencies on Linux to build and run nrk.

1. cd kernel
2. python3 ./run.py

If you just want to compile the code you can also execute:

1. RUST_TARGET_PATH=`pwd`/src/arch/x86_64 xargo build --target=x86_64-nrk

in the kernel directory (run.py will do that on your behalf).

To run the unit tests of the kernel:

1. cd kernel
2. RUST_BACKTRACE=1 RUST_TEST_THREADS=1 cargo test --bin nrk

To run the integration tests of the kernel:

1. cd kernel
2. RUST_TEST_THREADS=1 cargo test --features smoke --test integration-test

If you would like to run a specific integration test you can pass it with --:

1. RUST_TEST_THREADS=1 cargo test --test integration-test -- --nocapture userspace_smoke

Note: Parallel testing is not possible at the moment due to reliance on build flags for testing.

Update latest master:

1. git checkout master
2. git pull
3. git submodule update --init

Create a new feature branch:

1. git checkout -b <BRANCH-NAME>
2. Make changes in code.

Make sure that the code compiles without warnings, is properly formatted and passes tests:

1. cd kernel
2. bash commitable.sh

Commit changes and push

1. git add <CHANGED-FILES>
2. git commit
3. git push -u origin <BRANCH-NAME>
4. Create a Pull Request on GitHub.
