Why CPU Freq Crosses Hardware Limits and Policy Limits, and System Heat Up after Hybrid Sleep, in Debian 12 (Testing-Weekly) with auto-cpufreq? #525

Closed aluva closed 1 year ago

aluva commented 1 year ago

Installed auto-cpufreq and thermald, with auto-cpufreq.confwhile on charger:

governor = performance
scaling_max_freq = 1900000
turbo = auto

And, /etc/default/grub edited as:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable"

Thought it is conflicting/ redundant with some other tools. So, REMOVED all other tools: tlp cpufreq cpupower acpi acpid acpi-support linux-cpupower cpufrequtils cpulimit

OS: Debian 12 (bookworm: testing-weekly) Hardware: (Apple: amd64, 16 GB RAM, 8 CPU) limit: 800 MHz - 2800 MHz

After each REBOOT, everything (CPU Freq, Temperature, etc.) stays within limits, as set in auto-cpufreq.conf.

But, AFTER each Hybrid Sleep, things go out of control: (CPU Freq near 4000 MHz, Temp 95℃, Fan 4900 RPM, etc).

What am I missing?

I never encountered anything like that during suspend, hibernate or hybrid sleep and settings stay as they are.

I resolved it. I will write details about it. Perhaps, it can be used as an 'aside'. Because, I noticed that many people struggle with similar issues.. Adnan: With gratitude and immense thanks, for this path-breaking tool. Hats Off to you and the team working on it !!
