As I mentioned that data is taken from External Design Specification for Ice Lake server which is accessed using Intel account. I'm not completely sure it is right to make changes in open source project like Linux or Xen based on information which is not publicly available yet. But Intel is frequently doing this with Linux : even my second patch uses data taken from one of these documents and was committed by Intel to Linux first. Do we need the information publicly available to commit these changes as well? If not, we can run with these changes in our patchqueue until it gets out properly. Igor
