The AMD dev site links to blog posts of OpenCL 2.0 features (and probably other stuff) lead to dead pages. For example the article links at Overview of OpenCL 2.0 hardware support, samples, blogs and drivers - StreamHPC or the 'head over to the blog' link at http://developer.amd.com/amd-accelerated-parallel-processing-app-sdk/opencl-2-0-samples/ .
Thanks for reporting. Indeed, those blog links seem not working anymore (except this newer one: http://developer.amd.com/fine-grain-svm-with-examples/ ). I'll check with the concerned team for information.
