Hi,
I wonder what to do with the scaling_max_freq, base_frequency and
scaling_min_freq.
$ grep model\ name /proc/cpuinfo | sort -u
model name : 13th Gen Intel(R) Core(TM) i3-13100
$ cat /sys/devices/system/cpu/cpu0/cpufreq/*driver
intel_pstate
Those are the specifications as provided by Intel [1]:
Max Turbo Frequency [GHz] Up to 4.5
Performance-core Max Turbo Frequency [GHz] Up to 4.5
Performance-core Base Frequency [GHz] Up to 3.4
This are the defaults provided by /sys/devices/... :
$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
5800000
5800000
5800000
5800000
$ cat /sys/devices/system/cpu/cpu*/cpufreq/base_frequency
4400000
4400000
4400000
4400000
$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_min_freq
800000
800000
800000
800000
Is it safe to keep those values or should I set the max to 4500000 and
base to 3400000? Is the min value 800000 good or bad?
I will stay with powersave, excepted when doing real-time audio work,
than I'll select performance.
Years ago I read that real-time audio users disabled hyper-threading.
I wonder if it's still necessary to select the performance governor and
to disable hyper-threading for audio work.
Regards,
Ralf
