It seems like all nouveau_switcheroo_optimus_dsm() does here is check
nouveau_dsm_priv.optimus_detected/optimus_skip_dsm. Why not just make
add a function to check these that we call when setting up the DRM
device, then store the result of that into drm->runp...

[PATCH 0/5] Potential fix for runpm issues on various laptops
While investigating the runpm issues on my GP107 I noticed that something
inside devinit makes runpm break. If Nouveau loads up to the point right
before doing devinit, runpm works without any issues, if devinit is ran,
not anymore.
Out of curiousity I even tried to "bisect" devinit by not running it on
vbios provided signed PMU image, but on the devinit parser we have inside
Nouveau.

[PATCH v2 0/4] Potential fix for runpm issues on various laptops
CCing linux-pci and Bjorn Helgaas. Maybe we could get better insights on
how a reasonable fix would look like.
Anyway, to me this entire issue looks like something which has to be fixed
on a PCI level instead of inside a driver, so it makes sense to ask the
pci folks if they have any better suggestions.
