lsgpu-api

lsgpu is a lightweight C++17 library for querying GPU information using Vulkan. It provides a clean, cross-platform API without exposing Vulkan headers.

---

Features

• Detects all GPUs on the system.
• Reports GPU properties:
  • Name
  • Device ID
  • Vendor ID
  • VRAM size
  • Discrete vs integrated
  • Vulkan API version
• Minimal dependencies:
  • Only requires Vulkan, and <cstdint> (also <cstring> but it's in the library, not the header)
• C++ STL-free header

Installation

git clone https://github.com/iDontHaveTime/lsgpu-api.git
cd lsgpu-api

mkdir build
cmake -S . -B build
cmake --build build

./build/lsgpu

API Usage

• Create a system object to initialize Vulkan and query GPUs:

lsgpu::system sys;
if(!sys){
    // error
}

• You can then iterate through GPUs with a C++'s for range loop like this:

for(const lsgpu::gpu& gpu : sys.gpus()){
    std::cout<<gpu.get_name()<<std::endl; // prints out the gpu's name
}
