cpufreq does not work

[sabquat]

Got following error with cpufreq-

$ cpufreq --help
Traceback (most recent call last):
  File "/home/serlop/anaconda3/bin/cpufreq", line 8, in <module>
    sys.exit(main())

    c = cpuFreq()

    dataf = cpuFreq.__instance.__read_cpu_file(fpath)
  File "/home/serlop/anaconda3/lib/python3.8/site-packages/cpufreq/cpufreq.py", line 90, in __read_cpu_file
    with open(fpath, "rb") as f:
FileNotFoundError: [Errno 2] No such file or directory: '/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies'

Apparently, Intel has stopped publishing available frequencies. However, it is still possible to calculate the available frequencies using min, max, and the number of available frequency steps.

FYI, I am using Ubuntu 18.04 LTS and i5-10400

Well in fact this API was designed to work with the acpi-cpufreq driver, some features might work with the intel-pstate but is not guaranteed.

I got a similar issue in macOS, Macbook Pro M1 ARM architecture. This is a problem code and result.

import psutil
print(psutil.cpu_freq().max)

.
.
  File "/Users/user/miniconda3/lib/python3.10/site-packages/psutil/_psosx.py", line 179, in cpu_freq
    curr, min_, max_ = cext.cpu_freq()
FileNotFoundError: [Errno 2] No such file or directory (originated from sysctl(HW_CPU_FREQ))

When I searched, still this is a problem for M1 users. Are there any solutions?
