Hi I installed nmon-16m on gentoo 64bit on a Raspberry Pi 400. Unfortunately the MHz by thread & CPU doesn't work. The frequency is available from /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq in kHz. Afaik the CPUs use all the same frequency. scaling_available_frequencies gives the available frequencies since the max frequency can be changed to over- and underclock. Thanks for the nice software Jens
