MangoHud always displays Throttling Power

[fuzunspm]

Even with very very low load it always displays Throttling Power

Below screenshot was taken from a main menu with fps limit set to 60. it should not display the throttling power text here. It also displays Temp text from time to time for half a second but my gpu temps never exceeds 58 C degree

[flightlessmango]

Is it nvidia or amd?

[fuzunspm]

Both are amd
R5 2600
6700XT

[flightlessmango]

Throttling is only for GPU currently. How are you verifying that you're not actually power throttled?

[fuzunspm]

Total power draw is almost half of what I got. Other than that I don’t understand how main menu or even limited glxgears could cause power throttling. I don’t have performance problems in games either

[flightlessmango]

A power throttling case is lowering the power to save on power in low use scenarios

I also have a 6700XT and see the same thing, so is this normal behavior?

[flightlessmango]

I can't say it's not normal behavior, but I am fairly sure that there isn't a bug in mangohud. I'm leaning towards it being normal or there is a bug in the amdgpu kernel driver

Yeah I'm not sure either as I've only ever used this card in this OS so since I have nothing to compare against I wouldn't know if it's impeding my performance but as everything I run works great it's fine just a curious thing I noticed.

Same problem with a RX 6700 XT
Both throttling power & temp showing even in menu screens

Exactly the same here with an RX 6750 XT. Fedora 36 Kernel 5.19.15.

[MCPO-Spartan-117]

Kernel 5.12.19 showed it like expected, kernel 6.1.2 always shows it.

[Dim-P]

Same here, RX 6600 on Nobara (kernel 6.0.14).

[flightlessmango]

I have no reason to believe this is an issue with mangohud and rather an amdgpu issue.
It would be great if someone could make an issue over there https://gitlab.freedesktop.org/drm/amd/-/issues

[youmukonpaku1337]

happens on an rtx 3050ti laptop too

same with rtx3060 laptop

[Umio-Yasuno]

I have created an issue in drm/amd for this issue.

AMDGPU patch for Navi22/Navi23/Navi24.
But I tested only on Navi23.

The AMDGPU patch has been merged into Linux Kernel v6.1.47 and v6.4.12 .

[czak]

Thank you @Umio-Yasuno 🎉 I can confirm throttling indicators disappeared on 6.1.47 for me (6600XT).

[awsms]

@mrphs7019 @youmukonpaku1337 i assume you guys are still experiencing too?

[youmukonpaku1337]

yeep i am

[awsms]

I'm nowhere near as good as yasuno when it comes to programming, so I'd have no idea what to patch in the nvidia-drm module. if someone experienced with NVIDIA's stuff wants to have a look at it....

[mrphs7019]

@awsms idk i deleted mangohud

[awsms]

@mrphs7019 @youmukonpaku1337 the reason was... my vBIOS is throttled to 80W on Linux. i flashed a vBIOS from another manufacturer and the issue is gone. I highly suspect that's the case for u too, hence the @

[youmukonpaku1337]

nope. my vbios is 130w, highest for this card
