Latest version seem to suppress displaying "lap detected" degradation, but CPU goes down to 400Mhz anyway

Ubuntu 23.04, Lenovo ThinkPad P14s Gen 1, Intel® Core™ i7-10610U × 8, up-to-date BIOS.
Kernel: 6.2.0-35-generic #35-Ubuntu SMP PREEMPT_DYNAMIC Tue Oct 3 13:14:56 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux.

After applying your latest code, when running on A/C (performance mode) on laps, CPU goes down to 400MHz for some time after shaking.
The s-tui tool indicates thermal did not exceed 55-60C, so does not seem to be a thermal-caused throttle.
Both /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor and powerprofilesctl show "performance" profile (powerprofilesctl states "Degraded: no")
Tried to force higher CPU frequency when observing 400MHz, but no tool succeeds.
To restore higher CPU frequency, I either just need to wait steady a minute or so or to unplug A/C adapter.
I tried to use and also tried to remove all the other CPU/thermal related tools I knew I have (cpufreq-auto, thermald). Also disabled intel_pstate driver, but the bad behavior persists on ACPI too.

I'd appreciate suggestions what logs, diagnostics, outputs can be useful for diagnosing the issue.

I did not experience this issue. Are you sure this kernel module is causing it, like it only happens after installing it?

Btw, I've had a few instances where even though powerprofilesctl doesn't report lap-detected anymore, power profile still switches to power saver after a while.

Sorry to hear you've having this issue! I apologize but I no longer have a laptop with this acceleration sensor so can't reasonably maintain this repository.
