Vulkan User Guide

This guide shows how to install Vulkan components and verify that Vulkan works on the Dragon Q6A (Mesa Turnip driver).

Install 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

Run vulkaninfo

radxa@dragon-q6a$

vulkaninfo

If you can see output like driverName = turnip and deviceName = ... Adreno ..., Vulkan is working.

Run vkpeak

vkpeak is a simple Vulkan benchmark that can help quickly confirm the GPU and driver are working.

Build 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)"

Run vkpeak:

radxa@dragon-q6a$

cd ./vkpeak/build
./vkpeak 0

The output result is as follows:

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