Hello,
Can you run the auto plan with debugging enabled so I can see the output of your machine?
pstate-frequency -dd -Sp auto
It could be a regression with automatic plan setting.

I dont believe this is the desired configuration for anyone as in most systems it will make the laptop unresponsive.

CPU_MAX is set to 11% as you can see
I think its related to this file config: https://github.com/pyamsoft/pstate-frequency/blob/master/res/plans/01-powersave.plan
Thanks for the update.
When you run the script, is your machine connected to the AC power adapter, or are you on battery power?
The powersave
plan by default sets everything to the lowest performance value, which for your machine is 11% of the max CPU frequency.
The plan is performing as expected, if the minimum value is too low for your purposes, you can edit the powersave
plan to a more sane CPU_MAX
value, such as 30 or 40%.
Alternatively, you can edit the auto
plan to call the balanced
plan on both AC and battey.
I understand I can change it, and that is what I did. I know its working as intended with those settings, im not saying its a bug of the software, but I dont think anyone wants a CPU at CPU_MAX=11% or similar. I dont see anyone wanting to run at 400 or 800 Mhz by default.
Maybe the default for auto should be balanced
or the powersave
should set it to 30% by default.
Thoughts?
The latest version which is 3.9.4 will default to the AC plan if no battery is found on the machine.
I will think about bumping the minimum
Think I'll bump the shipped minimum to 50.
Now that modern processors have become so efficient, they are mostly able to handle themselves.
A minimum of 50 should give reasonale performance for a machine on battery where the general goal is to be as idle as possible to conserve energy.
Hope this will help.
That sounds great, in my experience anything that disabled turbo with balance_power p state profile is normally great for battery. 50 should keep the system responsive while providing good saving benefits
3.9.6
powersave default CPU_MAX
is now set as 50
.
In the future I will try to add support for a syntax such as +n
for example +30
which will mean 30 higher than the CPU_MIN
. This should allow for more dynamic system configuration.
The default configuration of the service/udevd makes it so by default it uses
00-auto.plan
which in term uses01-powersave.plan
. The problem is this plan setsPLAN_CPU_MAX=0
on many cases resulting on max Mhz being = to the min Mhz. I dont believe this is the desired configuration for anyone as in most systems it will make the laptop unresponsive.
