Hello. I'm playing with Carrizo APU and trying to find a way to remove the cache coherency within GPU (L2 cache is synchronization point for GPU) so that GPU's update is visible to CPU without tearing down the wavefront or kernel. Is there any OpenCL API or assembly instruction that can disable caching in GPU (GCN3)? Thank you!
