[Kernel-packages] [Bug 1738534] Re: Processor turbo dsiabled/throttled after suspend
The problem still persists.

It may have been as early as the upgrade to 16.04. I remember having some performance/overheating issues at that time so I disabled intel_pstate for a while; but I never fully diagnosed the issue. The 17.10 install was a fresh install though, I wiped the system.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

[Kernel-packages] [Bug 1738534] Re: Processor turbo dsiabled/throttled after suspend
As a workaround, I created a post-resume script that runs the above
commands at /lib/systemd/system-sleep/throttle-workaround. It works in
the first scenario, but not if the full power cycle was done on battery
power.
#!/bin/sh
# Action script to prevent CPU throttling after resume.

Title:
Processor turbo dsiabled/throttled after suspend
Status in linux package in Ubuntu:
Confirmed
Bug description:
After suspending/resuming my laptop on battery power, I noticed choppy
video playback. I've narrowed it down to the CPU being locked to
lower frequencies after suspend/resume (only on battery). Plugging
the laptop back in does not restore the normal performance, nor does
suspend/resume after plugging it back in. The performance doesn't
drop until after the suspend/resume, I'm not sure if it is _supposed_
to throttle when on battery, but either way the behaviour is wrong.
Doing a full shutdown and restart restores the performance to normal.
Prior to a suspend/resume cycle, cpupower reports:

no effect) and turbo is disabled:

Trying to re-enable turbo mode by setting the no_turbo intel_pstate

$ echo 0 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo

tee: /sys/devices/system/cpu/intel_pstate/no_turbo: Operation not permitted
However, these two commands *do* work around the problem, forcing
turbo mode back on and then restoring the normal frequency range:
sudo x86_energy_perf_policy --turbo-enable 1
sudo cpufreq-set -r --min=0.8GHz --max=3.0GHz
I also see this error in dmesg after some resumes (but the above
problem sometimes happens without this error message):

[Kernel-packages] [Bug 1738534] Re: Processor turbo dsiabled/throttled after suspend
Just tried another scenario. If I do the full power cycle while on battery power, then it boots up with turbo disabled and frequency locked. This command then seems to work (cpupower then reports turbo is active/supported): sudo x86_energy_perf_policy --turbo-enable 1 But this command has no effect: sudo cpufreq-set -r --min=0.8GHz --max=3.0GHz (Where, int he previous scenario, it did work.) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1738534 Title: Processor turbo dsiabled/throttled after suspend Status in linux package in Ubuntu: New Bug description: After suspending/resuming my laptop on battery power, I noticed choppy video playback.
