Running Quadro M1000M, no crash running Nouveau (just poor perf as everybody)

Well, if I select intel through prime, the line nouveau.run-pm=0 is put in kernel parameters in grub. I've excluded nvidia & nouveau from runtime pm in tlp, to not interfere here.
The result is that I get 15 W power usage.

If I delete the nouveau.run-pm=0 kernel option & update grub, and if I do not exclude nvidia nouveau from runtime pm in TLP, I get 5 W running the same backlight & wifi settings.

cat /sys/kernel/debug/vgaswitcheroo/switch shows
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Off:0000:01:00.0
too, but anyway the FACT is that the power usage on my Dell 7510 is much higher, and is 100 % related to some stuff involving nvidia/prime.
