Linux driver 570.124.06 reports silly power draw on mobile GPU

Hi,

This does not seem to influence me in a meaningful way at the moment, but I noticed that with driver 570.124.06 on Ubuntu 24.04 on my laptop, I would see:

More in detail, I see:

    GPU Power Readings
        Average Power Draw                : N/A
        Instantaneous Power Draw          : 749.67 W
        Current Power Limit               : 35.00 W
        Requested Power Limit             : 35.00 W
        Default Power Limit               : 35.00 W
        Min Power Limit                   : 1.00 W
        Max Power Limit                   : 45.00 W

It’s of course the 750 Watts that is the silly value. ;-)

People might very well be aware of this already, but with a quick search I couldn’t find an existing thread on it.

Curiously, after bringing my laptop back from sleep just now, it now shows:

So the issue is clearly quite circumstantial…
