Installation

  • Release version: cargo install cargo-qemu-runner

Usage

  • Put runner = "cargo qemu-runner" in your .cargo/config.toml's [target] section
  • Specify these keys under it:
    • limine-branch, the limine binary branch to clone
    • extra-files, specifies extra files to copy to the resulting image
    • test-success-exit-code, qemu exit code which is considered success
