Hi! I'm debugging overheats on v4.9-rc1... which did not seem to happen in v4.8-rc1. I'm running basically "nice make -j 3" on kernel... cpus are fully loaded. %Cpu(s): 7.5 us, 18.5 sy, 72.6 ni, 0.0 id, 0.0 wa, 0.0 hi, 1.5 si, 0.0 st KiB Mem: 3087096 total, 2993076 used, 94020 free, 52900 buffers KiB Swap: 1681428 total, 60900 used, 1620528 free. 1183664 cached Mem Still, cpus don't stay on maximum frequency on v4.8-rc1. (I suspect that may be why machine does not overheat). pavel@duo:/data/l/linux$ sudo cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq ; sudo cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq ; sudo cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq ; sudo cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq ; sudo cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq ; sudo cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq 1833000 1833000 1000000 1000000 1000000 1000000 1833000 1833000 1833000 1833000 1000000 1000000 pavel@duo:/data/l/linux pavel@duo:/data/l/linux$ grep -i . /sys/devices/system/cpu/cpu0/cpufreq/* /sys/devices/system/cpu/cpu0/cpufreq/affected_cpus:0 /sys/devices/system/cpu/cpu0/cpufreq/bios_limit:1833000 grep: /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq: Permission denied /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq:1833000 /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq:1000000 /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency:10000 /sys/devices/system/cpu/cpu0/cpufreq/freqdomain_cpus:0 1 /sys/devices/system/cpu/cpu0/cpufreq/related_cpus:0 /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies:1833000 1333000 1000000 /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors:conservative powersave schedutil ondemand performance /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq:1833000 /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver:acpi-cpufreq /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor:ondemand /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq:1833000 /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq:1000000 /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed: grep: /sys/devices/system/cpu/cpu0/cpufreq/stats: Is a directory Is that expected behaviour?
