OpenCL on QCS405 fails

Hi

I'm trying to query the PlatformIDs on a QCS405 chip running linux with a very simple program, and I'm getting error -30 (CL_INVALID_VALUE).

    cl_uint n = 0;
    cl_int err = clGetPlatformIDs(0, NULL, &n);
    std::cout << err << std::endl;

I got the libOpenCL.so file from ChipCode bundle qcs40x-2021-spf-1-3_ap_standard_oem.

What could be wrong?
 
# cat /sys/devices/platform/soc/1c00000.qcom,kgsl-3d0/kgsl/kgsl-3d0/gpu_model 
Adreno306v33
# cat /sys/devices/platform/soc/1c00000.qcom,kgsl-3d0/kgsl/kgsl-3d0/gpuclk 
400000000

Hi, stu_iliev

It seems OpenCL driver does not work. Do you check if OpenGL work on your QSC405 dvice or not also?

Thanks

Can you verify if below clinfo can run on your QSC405 device?

clinfo tool   https://github.com/Oblomov/clinfo/tree/master/src

Thanks
