I like the initiative here. It is always good to have a single code base. One question. I see that there is a tool at https://github.com/intel/intel-cmt-cat to test and verify the functionality of resctrl feature. I also see some of the distros have this tool already. Is this tool going to replace intel-cmt-cat? I have not looked at the patches closely yet. > > We introduce resctrl selftest to cover resctrl features on both > X86 and ARM architectures.
