Description
NVIDIA Open GPU Kernel Modules Version
525.60.11
Does this happen with the proprietary driver (of the same version) as well?
Yes
Operating System and Version
Pop!_OS 22.04 LTS
Kernel Release
Linux pop-os 6.0.12-76060006-generic #202212290932167165296522.04~452ea9d SMP PREEMPT_DYNAMIC Wed D x86_64 x86_64 x86_64 GNU/Linux
Hardware: GPU
GPU 0: NVIDIA GeForce RTX 3050 Laptop GPU (UUID: GPU-b2f720a1-2b4e-9b17-4383-76f9361248a2)
Describe the bug
The maximum power the GPU on the Lenovo Ideapad Gaming 3 15ACH6 can use is 85W , On Windows that is the case under heavy workloads
But on Linux with dynamic boost enabled and nvidia powerd running , the power is limited to 64W
Or 75W if i switch my laptop to performance mode and reboot my system
(Linux dsitro doesn't really matter since this is a driver bug)
To Reproduce
I used "Portal with RTX" to showcase this bug but this bug happens on any graphically demanding application
The full power of my GPU is just not being utilized
On Windows this game was using 85W at the same area
Mangohud was used to measure the power usage on linux

Research direction
Start by reviewing the attached nvidia-bug-report.log.gz and the reported dynamic boost and nvidia powerd behavior on the Lenovo Ideapad Gaming 3 15ACH6. Reproduce with Portal with RTX or another demanding application while measuring with MangoHud; done means the RTX 3050 Laptop GPU can reach its stated 85W limit under Linux.
