Vulkan 使用指南

本教程用于在 Dragon Q6A 上安装 Vulkan 相关组件并验证 Vulkan 是否可用（Mesa Turnip 驱动）。

安装 Vulkan

radxa@dragon-q6a$

sudo apt update
# mesa-vulkan-drivers: Vulkan ICD (Turnip/Freedreno)
# vulkan-tools: provides vulkaninfo
sudo apt install -y mesa-vulkan-drivers vulkan-tools

运行 vulkaninfo

radxa@dragon-q6a$

vulkaninfo

若输出中能看到类似 driverName = turnip / deviceName = ... Adreno ...，说明 Vulkan 已正常工作。

运行 vkpeak

vkpeak 是一个简单的 Vulkan 性能测试工具，可用于快速验证 GPU 跑分与驱动工作状态。

构建 vkpeak：

radxa@dragon-q6a$

sudo apt install -y git cmake g++
git clone https://github.com/nihui/vkpeak.git
cd vkpeak
git submodule update --init --recursive

mkdir build
cd build
cmake ..
cmake --build . -j"$(nproc)"

运行 vkpeak：

radxa@dragon-q6a$

cd ./vkpeak/build
./vkpeak 0

输出结果如下：

device       = Turnip Adreno (TM) 643
driver       = turnip Mesa driver / Mesa 25.2.8-0ubuntu0.24.04.1
