fail to use opencl on i.mx6Dual

[zhengfudi]

Hi, i am trying to use opencl on i.mx6Dual with BSP_Linux_3.14.28, but it returned -1001 when invoke clGetPlatformIDs(1, &platform_id, &platforms). I have checked CONFIG_MXC_GPU_VIV in kernel config, and "/dev/galcore" is also exist after bootup.

Does BSP_Linux_3.14.28 or i.mx6Dual not support opencl EP ? How to get a BSP supporting opencl?

Thanks a lot.

Hi zheng

bsp supports it, please refer to attached Linux Manual

Chapter 13 Graphics Processing Unit (GPU). For usage one can refer to

OpenCL Hello World

Where can we find the OpenCL BSP for i.MX6 Android?

Best regards

igor

Hi igorpadykov

Thank you for your reply.

Actually, I configured the kernel refer to "Chapter 13 in Linux Manual", and copied the application code from "OpenCL Hello world". The programs compiled, linked and run success, but application invokes clGetPlatformIDs interface fail, return value is -1001. What is the cause of the problem may be?
