OpenCL driver works on ROCK Pi 4
Install libmali package
Install libmali package from Radxa APT's testing repo.
$ sudo apt-get install rockchip-mali-midgard14 $ sudo apt-get install rockchip-mali-midgard-dev
Sanity Checkout with clpeak
To see if the opencl driver works properly on ROCK Pi 4, use the benchmark tool clpeak
$ sudo apt-get update && sudo apt-get install cmake git g++ $ git clone https://github.com/krrishnarraj/clpeak $ mkdir clpeak/build $ cd clpeak/build $ cmake .. $ make -j$(nproc) $ ./clpeak
After executing command clpeak, there shall be the following outputs:
