How to install OpenCL/Kronos/OpenGL on CM5-EVB

tmb68

Can anyone provide the steps required to install OpenCL/Kronos/OpenGL on the CM5-EVB?

Looking for support for the Mali-G610, not seeing UserSpace files on ARM or Rockchip sites.
Thanks,

The released Ubuntu system image is already integrated with G610 driver by default

I was able to get the OpenGL glmark working with libgles2-mesa, and -dev, and mesa-utils install, but I am still stuck on OpenCL.

When I try to compile and run a test OpenCL, I am getting :
ClGetPlatformIDs (-1001)
no platforms found.

For example, for the RockPi4:
https://wiki.radxa.com/Rockpi4/dev/install-opencl
There is a mali-midgard package which installs the OpenCL backend for the Mali.

So, I would expect there are packages available for generic ARM, NEON, MALI-G610 somewhere. Once installed, I should be able to see all of those as platforms to run OpenCL against.

Thanks,

@tmb68 The following figure shows the test results of OpenCl, and the testing method will be provided later.

@tmb68 The OpenCL library file has been updated. Run the following command to update it:

sudo apt-get update
sudo apt-get upgrade
