clinfo not detetcting GPU device for the AMD A10 APU

Question asked by johnspaul92 on Feb 4, 2016

I have a machine with an AMD A10 APU. I installed the latest driver from the AMD website to support OpenCL 2.0. But when i do a clinfo the output only shows 1 device of type CPU. Shouldnt it detect the GPU as well? Also in the platform version is shown as OpenCL 2.0. But towards the end the openCL driver version is shown as 1.2. Why does this happen?


The output of clinfo is shown below:
