A sample UEFI application written in Rust using the efi crate.

Building

To build follow the below steps:

1. Unless already installed, install cargo-xbuild by running cargo install cargo-xbuild.
2. Execute the build by running cargo xbuild --target x86_64-unknown-uefi
3. When the build complete the resulting EFI application efi_app.efi will be found in target\x86_64-unknown-uefi\debug\. Load this up in qemu and run it via EFI shell. You can find an OVMF binary for your use in the directory tools of this repo.

Build steps have been tested only on Windows. Building on non-Windows OS's might work. Currently only x64 architecture is supported.
