Tashkinov (aros@gmx.com) --- Created attachment 305659 --> https://bugzilla.kernel.org/attachment.cgi?id=3D305659&action=3Dedit The contents of /sys/devices/system/cpu/cpufreq/* Switching between power modes using /sys/devices/system/cpu/cpufreq/*/energy_performance_preference does nothin= g. The exact per CPU frequency stats: # cat /sys/devices/system/cpu/cpufreq/policy*/scaling_cur_freq 400000 544395 400000 544099 400000 400000 400000 400000 400000 544189 400000 544181 400000 400000 544007 542947 No idea where 544MHz comes from. BTW here's another bug, either firmware or something in the kernel reports wrong max frequency: # cat /sys/devices/system/cpu/cpufreq/policy*/scaling_max_freq 5137000 6080000 6080000 5764000 5764000 5924000 5924000 5137000 6080000 6080000 5608000 5608000 5293000 5293000 5449000 5449000 I'm not aware of any Zen 4 CPUs which can run at 6080000KHz frequency by default, let alone mobile parts. --=20 You may reply to this email to add a comment.
