= OpenCL driver works on ROCK Pi 4 =

== Install libmali package ==

$ 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
$ git clone https://github.com/krrishnarraj/clpeak
$ cd clpeak
$ cmake . -DCMAKE_CXX_COMPILER=g++
$ make
$ ./clpeak

After executing command '''clpeak''', there shall be the following outputs:
