Hi all
I am trying to get OpenCL working with the Nouveau driver instead of the Nvidia proprietary one.
My GPU is properly installed and seen by the system. Here below is the output ofinxi -SGxxz --display
System: Kernel: 5.3.18-lp152.33-default x86_64 bits: 64 compiler: gcc v: 7.5.0 Desktop: N/A
dm: SDDM Distro: openSUSE Leap 15.2

I have mesa-libopencl installed and other related elements.

However, clinfo doesn’t found any device connect to the OpenCL platforms and my application requiring OpenCL doesn’t find it either.
