[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.
Original cover letter:
While investigating the runpm issues on my GP107 I noticed that

[PATCH v5 00/13] Fix connector probing deadlocks from RPM bugs
This is the latest version of https://patchwork.freedesktop.org/series/46815/
I moved everything out of fb_helper and back into nouveau, because it
seems that other drivers actually do have this handled already as far as
I can tell.
