Hi, On my desktop Zen 3 (Vermeer) system applying this series yields a new warning message on each boot: > Oct 16 06:20:41 kernel: Could not retrieve highest performance (-19) As I see it, this is one of the pr_debug()s newly promoted to warnings. Is there anything I can provide to help fix this? Just for completeness: ``` $ cat-files /sys/devices/system/cpu/cpufreq/policy0/* /sys/devices/system/cpu/cpufreq/policy0/affected_cpus 0 /sys/devices/system/cpu/cpufreq/policy0/amd_pstate_highest_perf 231 /sys/devices/system/cpu/cpufreq/policy0/amd_pstate_hw_prefcore enabled /sys/devices/system/cpu/cpufreq/policy0/amd_pstate_lowest_nonlinear_freq 1746000 /sys/devices/system/cpu/cpufreq/policy0/amd_pstate_max_freq 5274000 /sys/devices/system/cpu/cpufreq/policy0/amd_pstate_prefcore_ranking 231 /sys/devices/system/cpu/cpufreq/policy0/boost 1 /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_max_freq 5274000 /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_min_freq 550000 /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_transition_latency 0 /sys/devices/system/cpu/cpufreq/policy0/energy_performance_available_preferences default performance balance_performance balance_power power /sys/devices/system/cpu/cpufreq/policy0/energy_performance_preference balance_performance /sys/devices/system/cpu/cpufreq/policy0/related_cpus 0 /sys/devices/system/cpu/cpufreq/policy0/scaling_available_governors performance powersave /sys/devices/system/cpu/cpufreq/policy0/scaling_cur_freq 1746000 /sys/devices/system/cpu/cpufreq/policy0/scaling_driver amd-pstate-epp /sys/devices/system/cpu/cpufreq/policy0/scaling_governor powersave /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq 5274000 /sys/devices/system/cpu/cpufreq/policy0/scaling_min_freq 1746000 /sys/devices/system/cpu/cpufreq/policy0/scaling_setspeed <unsupported> $ grep -w cppc /proc/cpuinfo <empty> ``` Thanks, -- Ivan Shapovalov / intelfx /
