Hi Nouveau developers, We've posted a short document about disabling display underflow reporting on GK104, which is needed due to an incorrect setting in some production GK104 VBIOSes: ftp://download.nvidia.com/open-gpu-doc/gk104-disable-underflow-reporting/1/gk104-disable-underflow-reporting.txt Thanks, - Andy

this gk104 volt implementation has to be reworked a little, because the speedo readout in maxwell doesn't need those strange 0 and 41 writes into 0x122634, but it needs this PWM thing. Maybe Maxwell is PWM only and we could just simplify it there, but without proper knowledge there has some refactoring t...

...ergating). Here's some very lazily done benchmarks on how much power this saves as well. It should be noted that chances are, these patches save a lot more power then you see here since clockgating works best when the GPU is under load.
