Hi, what are the missing bits to get nv50-class hardware into lowest power mode? Even when clocking down to perflvl 0, the GPU temperature of my Quadro FX 880M is still quickly climbing until it reaches 60 °C and the fan goes on for a while (I tried up to 2.6.38-rc1 so far - any progress in nouveau-next?). This is not only annoying but also sucking several watts more than what is feasible - unfortunate for mobile operation.
The benchmark is still the blob which runs the card at level 0 around 54 °C, and that means fan-less. But as the blob is causing increasing troubles across suspend/resume, not to speak of all its other limitations. So I'd rather like to switch ASAP now. What may cause this different power consumption? As the clocking is apparently the same (the blob even claims to use a few more MHz), I was wondering if the less sophisticated firmware of nouveau could be the reason. Or is the host driver keeping the GPU too busy even in idle state? Is there anything I could do to help analyzing or even resolving this issue? Thanks, Jan
