Here it shows my gpu support Dynamic Boost but in powerd it show the error

Here is the only option in my bios showing that if I enabled 3.0 it will disable Nvidia Dynamic Boost.

Hi @Syntist , thanks for reporting this issue.
Do you see Dynamic Boost failing even when the laptop is plugged in? Or is the failure just seen on battery?

Hi @vanditd Thanks for replying

I am getting the same error in both cases, Plugged and Unplugged.
I didn’t got this issue in 565 Release I guess.

Thanks @Syntist , could you attach a bug report for the 2 cases, once when the laptop is plugged in, and another on battery :

  1. systemctl stop nvidia-powerd → Connect AC adapter → systemctl start nvidia-powerd → take bug report
  2. systemctl stop nvidia-powerd → Remove AC adapter → systemctl start nvidia-powerd → take bug report

Bug Report

1- Connect AC Adapter

2- Remove AC Adapter

Here’s the bug report for both scenerio

Thanks @Syntist for the reports.

‘Connect AC Adapter’ Bug report :

Current Power Limit               : 35.00 W
Requested Power Limit             : 35.00 W
Default Power Limit               : 35.00 W

‘Remove AC Adapter’ Bug report :

Current Power Limit               : 35.00 W
Requested Power Limit             : 35.00 W
Default Power Limit               : 35.00 W

To confirm power limits are working properly, could you help to upload bug reports for both the cases with any GPU intensive application running when you take the reports?
Running any game or benchmark which is GPU intensive should work, eg, SOTTR. You can check if the GPU Power Readings are changing using the command nvidia-smi --query | grep Limits.

I think i am hitting my max watt that is 45 watt when i am connected to battery
But I am not sure why i am getting that error in powerd

Thanks @Syntist for the logs.
Based on the nvidia-smi output, the feature is working in both AC and DC. The system’s EC/BIOS mandates the dynamic boost behavior and disables the controller in certain conditions - like for example when the battery has low residual charge. The error print comes in syslog in such cases and the dynamic boost gets disabled.

@vanditd Thanks

I been playing out for a while, and I have notice some weird behavior, Before I guess the older version maybe 570..
My power setting was working correctly and as soon I start the game my laptop gpu max out watt, but now It takes a bit of time to rampup to 45 watt, sometime it just dont go that point. And I loose hell lot of performance compared to earlier release, but once it reach it max power then it works good

Hi @Syntist ,
Could you help to answer a few questions :

  1. Do you have a driver version after which you started noticing this issue?
  2. Does this happen on AC, DC, or both? Please take a bug report and attach it here when this happens.
  3. Are you seeing this in a particular game or is it seen across games?
