Incorrect TDP displayed on Loki Max in Bazzite.

Describe the bug
Mangohud displaying incorrect TDP on Ayn Loki Max in gaming mode on Bazzite

List relevant hardware/software information

• Bazzite Linux
• MangoHud version 0.7.1
• 680m

To Reproduce
Steps to reproduce the behavior:

1. Installed simpledeckytdp for TDP control on Loki Max
2. Set max TDP to 32w and default to 30w
3. Set power profile to performance
4. Installed Mangopeel plugin through decky loader
5. Set Mangohud background opacity to 0 and added battery power draw and screen resolution
6. Opened Remnant 2 and played at 900p medium settings
7. GPU showing 24.8w and CPU showing 30w with battery showing 58.3w

Expected behavior
Individual TDP for CPU and GPU as well as total battery power should reflect accurate information not greater than device capabilities

Screenshots
Screenshot attached

Additional context
Individual power draw on CPU and GPU equal higher than max TDP set in performance settings and well above device capabilities.

How do you know that the TDP limit is working?

[bramadeusbrozart]

The device is not able to hit 60w. The APU shuts down entirely approaching 40w. Aside from that, the temperatures on CPU and GPU are consistent with that of a device running at 30w over an extended period.

I think it's unlikely that this is a mangohud issue as we're just reporting what gpu_metrics outputs.
You will need to verify if gpu_metrics is wrong and in that case report it to the amdgpu kernel driver
