Efifetch

A simple system information tool for UEFI environments, designed to run directly from a UEFI-shell. efifetch aims to provide concise and useful system details in a format inspired by popular system fetch tools like fastfetch and neofetch, but tailored for the unique UEFI runtime environment.

Targets support

• x86_64-unknown-uefi
• i686-unknown-uefi
• aarch64-unknown-uefi

Installation & Setup

To build efifetch from source, you will need:

• Rust Toolchain (see MSRV in Cargo.toml)
• UEFI-shell for execution

1. Clone the repo:

   git clone https://github.com/yaroslav957/efifetch.git
   cd efifetch

2. Build UEFI executable:

   # build for x86_64-unknown-uefi, for example
   rustup target add x86_64-unknown-uefi
   cargo build --release

Running on real hardware

Copy UEFI-Shell executable & efifetch:

cp uefi-shell.efi /path/to/usb_drive/boot/efi/bootx64.efi
cp target/x86_64-unknown-uefi/release/efifetch.efi /path/to/usb_drive/efi/boot/

Running on virtual machine

To run efifetch on VM, you will need:

• Firmware files
• QEMU virtual machine

1. Install QEMU & OVMF:

   # Debian/Ubuntu
   sudo apt-get install qemu ovmf
   
   # Fedora
   sudo dnf install qemu-kvm edk2-ovmf

2. Copy Firmware files:

   cp /usr/share/OVMF/OVMF_CODE.fd .
   cp /usr/share/OVMF/OVMF_VARS.fd .

3. Copy UEFI-Shell executable & efifetch:

   cp uefi-shell.efi esp/efi/boot/bootx64.efi
   cp target/x86_64-unknown-uefi/release/efifetch.efi esp/

4. Run virtual machine

   qemu-system-x86_64 -enable-kvm \
   -drive if=pflash,format=raw,readonly=on,file=OVMF_CODE.fd \
   -drive if=pflash,format=raw,readonly=on,file=OVMF_VARS.fd \
   -drive format=raw,file=fat:rw:esp
