Kernel can be from mainline tree or tip. Thanks for the clarification, the way I wrote it was ambiguous, maybe somebody would think I needed some specific machine with some special/new hardware feature (some new Intel PT feature, that is), but I understood that this is purely a software/kernel feature, needing only a machine with "regular" Intel PT. - Arnaldo
