How to implement OpenCL atomic_inc on i.MX6Q

yanfengliu — Wed, 30 Dec 2015 06:56:30 GMT

It seems that the OpenCL support on i.MX6Q (at least with 3.10.17 BSP) doesn't have the built-in atomic functions such as atomic_inc() etc.

Are there ways to implement that function on i.MX6Q?

Hello Yanfeng,

The atomic functions are currently disable from OpenCL compiler, we are working to have another version of the driver of the GPU to support this functions in the near future. I do not have a date to provide but this are part of the pipeline.

Thanks for the updates. I will then use OpenCL for cases where such function is not needed with current version. :smileyhappy:

I just have met the same problem when i tried to build an application to achieve hough line transform with opencl, but "atomic_add/inc" was not supported, is there recent update support this function?
