We are really happy to see you happy.
1) Yes you are right. Current driver does not support OpenCL 2.0 on AMD CPUs.
2) Right now, fine grained SVM with atomics is only supported on AMD Kaveri APU on Linux 64-bit OS.
To understand the usage of fine grained SVM, you may check the following SDK samples: SVMAtomicsBinaryTreeInsert, FineGrainSVM, FineGrainSVMCAS
3) As mention in this thread Updated AMD OpenCL user’s guide – provide your feedback, we are in the process of updating the user guide and optimization guide. We have updated the optimization guide with relevant updates within the scope of this SDK release. Content of that table has not been updated and does not consider new feature like SVM.
