Enable X86_CPU_RESCTRL and PROC_CPU_RESCTRL config options.\n"); The resctrl tests do not depend on or exercise the code enabled when PROC_CPU_RESCTRL is set so there is no need to require users to enable it. It (PROC_CPU_RESCTRL) is automatically selected anyway if PROC_FS is enabled. An explicit check for the existence of /proc/{pid}/cpu_resctrl_groups would be required if somebody ever does add a resctrl test to exercise the code enabled by that config. There is no need to require that setting now. Thus could just be "resctrl FS does not exist. Enable X86_CPU_RESCTRL config option." > > filter_dmesg(); > Reinette
