sudo apt install clinfo
cd ~
sudo mv /etc/OpenCL/vendors/pocl.icd ~/Documents
wget https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
sudo apt-key add GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
echo "deb https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/oneAPI.list
sudo apt update
sudo apt install intel-oneapi-runtime-opencl -y
sudo apt install intel-oneapi-runtime-compilers intel-opencl-icd -y

Type clinfo and you should have atleast one platform listed.
