[Kernel-packages] [Bug 1738534] Re: Processor turbo dsiabled/throttled after suspend

2023-07-28 Thread wwweb
The problem still persists.
Using latest stable Debian 11 and having the same issue - every time after 
suspend CPU turbo is disabled.

5.10.0-23-amd64 #1 SMP Debian 5.10.179-2 (2023-07-14) x86_64 GNU/Linux

A workaround I've found is to edit /etc/sysfs.conf:

mode power/state = 0777
owner power/state = root:root
devices/system/cpu/cpu0/cpufreq/boost = 1
devices/system/cpu/cpu1/cpufreq/boost = 1
devices/system/cpu/cpu2/cpufreq/boost = 1
devices/system/cpu/cpu3/cpufreq/boost = 1
devices/system/cpu/cpu0/cpufreq/scaling_governor = performance
devices/system/cpu/cpu1/cpufreq/scaling_governor = performance
devices/system/cpu/cpu2/cpufreq/scaling_governor = performance
devices/system/cpu/cpu3/cpufreq/scaling_governor = performance

change scaling_governor to any other supported mode (ondemand,
conservative, etc.), then restart sysfsutils:

sudo service sysfsutils restart

and then change scaling_governor back to performance and restart
sysfsutils again.

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:

  $ sudo cpupower frequency-info

  Afterwards, the frequency is clamped (cpufreq-set -r --max=3.0GHz has
  no effect) and turbo is disabled:

  /sys/ entry back to 0 is rejected:

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

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:

  $ sudo cpupower frequency-info

The governor "powersave" may decide which speed to use
within this range.

  Afterwards, the frequency is clamped (cpufreq-set -r --max=3.0GHz has
  no effect) and turbo is disabled:

  Trying to re-enable turbo mode by setting the no_turbo intel_pstate
  /sys/ entry back to 0 is rejected:

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

2017-12-19 Thread Shaun Crampton
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.

I'll try the new kernels.

[Kernel-packages] [Bug 1738534] Re: Processor turbo dsiabled/throttled after suspend

2017-12-18 Thread Joseph Salisbury
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.

  Processor turbo dsiabled/throttled after suspend

Status in linux package in Ubuntu:
  Incomplete

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:

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.

2017-12-16 Thread Shaun Crampton
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.)
