New: CPU stuck to low frequency after resume from sleep
https://bugzilla.kernel.org/show_bug.cgi?id=218805
Bug ID: 218805
Summary: CPU stuck to low frequency after resume from sleep
Product: Power Management
Version: 2.5
Hardware: Intel
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: cpufreq
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Kernel version: 6.8.7 #1 SMP PREEMPT_DYNAMIC
Problem: On initial boot, everything works fine. After suspend-resume, intel_cpufreq policy is stuck well below hardware limits (1.32 Ghz instead of 3.30 Ghz), as seen below. Manually trying to raise the upper limit is not possible.
analyzing CPU 5:
driver: intel_cpufreq
CPUs which run at the same hardware frequency: 5
CPUs which need to have their frequency coordinated by software: 5 maximum transition latency: 20.0 us
hardware limits: 1.20 GHz - 3.30 GHz
available cpufreq governors: conservative ondemand userspace powersave
performance schedutil
current policy: frequency should be within 1.20 GHz and 1.32 GHz.
The governor "schedutil" may decide which speed to use within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 1.10 GHz (asserted by call to kernel) boost state support:
Supported: yes
Active: yes
25500 MHz max turbo 4 active cores
25500 MHz max turbo 3 active cores
25500 MHz max turbo 2 active cores
25500 MHz max turbo 1 active cores

--- Comment #2 from Artem S. Tashkinov ([email protected]) --- Could you try disabling/enabling turbo boost? I've seen bug reports where people say it helped them.
