AMD family processors do not show all cores in the output of turbostat. This occurs because AMD has multiple nodes per socket and enumerates cores within each node from 0. For example, socket 0 may have two nodes (0 and 1) and those nodes both have cores enumerated from 0 through 7. turbostat cannot handle this configuration, and as a result only shows 1/2 the cores in its output.
This patchset makes turbostate aware of nodes. It has been tested on various AMD and Intel systems and no issues have been found.
