Libegpu

Libegpu is a library for enumerating external GPU (eGPU) devices & enclosures.

✨ Features

• Enumerates PCIe-tunneled eGPU devices from AMD, NVIDIA, and Intel
• Enumerates USB-attached eGPU enclosures from Razer (e.g. the Razer Core X V2)
• Includes an lsegpu CLI tool for enumerating eGPU devices & enclosures
• Includes easy-to-use Python bindings to the Rust library (a work in progress)
• 100% free and unencumbered public domain software

🛠️ Prerequisites

• Rust 1.85+ (2024 edition) if building from source code

⬇️ Installation

Installation from PyPI

pip install -U egpu

Installation from Source Code

cargo install egpu

👉 Examples

Enumerating eGPU Devices

Python

import egpu

for device in egpu.devices():
    print(device)

Rust

for device in egpu::list_devices().unwrap() {
    println!("{:#?}", device);
}

Enumerating eGPU Controllers

Python

import egpu

for controller in egpu.controllers():
    print(controller)

Rust

for controller in egpu::list_controllers().unwrap() {
    println!("{:#?}", controller);
}

Enumerating eGPU Enclosures

Python

import egpu

for enclosure in egpu.enclosures():
    print(enclosure)

Rust

for enclosure in egpu::list_enclosures().unwrap() {
    println!("{:#?}", enclosure);
}
