OpenCL can not detect my AMD GPU using OpenCV
I am using AMD Radeon R9 M375. I tried following this answer https://stackoverflow.com/a/34250412/... but it didn't work for me.
I followed this: http://answers.opencv.org/question/10...
and my output shows this:
Platform Name: Intel(R) OpenCL
Platform Name: AMD Accelerated Parallel Processing
I am not able to implement the initializeContextFromHandler
suggested at the bottom of that post.
Here is my output from clinfo.exe

your so question is from 2015, the other one from 2016, all outdated.
there's no more cv::ocl, or the nessecity to do something like initializeContextFromHandler in the 1st place, now.
the output from clinfo is dandy, but entirely useless here. the only relevant lines seem to be:
but we probably need to see your cmake output !
also: opencv version ? if that's really 3.0, please update to latest master (or 3.4.1) noone can help you with such an outdated thing
Please look at the SO thread at the bottom of the post. It is resolved now. https://stackoverflow.com/questions/4...
if you could mention, how so here, we'd have an answer !
Should I answer my own question? Is that what you mean?
lol, why would i look at an SO post ?
yes, please either do write an answer, or at least a comment (we'll propell that to an answer)
Sure, no problem.
