Raspberry Pi 5 Limited OpenCL support with CLVK
I found an OpenCL driver that works on top of Vulkan.
As the Raspberry Pi 5 has a Vulkan driver, I was hoping to get OpenCL fully working.
Unfortunately currently there is no support for half or double precision. And I wasn't able to get Mandelbulber 2 working with OpenCL.
Install dependencies.
sudo apt install mesa-vulkan-drivers vulkan-tools libvulkan-dev git cmake clang clinfo gcc g++
You can build it by cloning the Github repository and follow the instructions.
https://github.com/kpet/clvk
git clone https://github.com/kpet/clvk
cd clvk
git submodule update --init --recursive
./external/clspv/utils/fetch_sources.py --deps llvm
mkdir -p build
cd build
cmake ../
make -j 1
I needed 16GB of memory total. As I have the 8GB Raspberry Pi 5, I added 8 GB swap memory.

sudo fallocate -l 8G /swapfile1
sudo chmod 600 /swapfile1
sudo mkswap /swapfile1
sudo swapon /swapfile1
