[PATCH 0/4] nouveau fixes for RPM/Optimus-related hangs
Hi,
Here are two patches to fix an issue reported on kernel bugzilla (infinite loop
due to unchecked function) and a more important fix to fix hanging Optimus
machines when runtime PM is enabled (with pm/pci patches).
An older (obsolete) patch for the first issue was tested by the reporter:

[PATCH v3 0/4] nouveau RPM fixes for Optimus (final)
Hi,
Here are two patches to fix an issue reported on kernel bugzilla (infinite loop
due to unchecked function) and a more important fix to fix hanging Optimus
machines when runtime PM is enabled (with pm/pci patches).
These are the final patches targeting v4.8. Changes compared to v2[1]:
collected R-b from Hans and Mika and fixed a minor comment style issue.
I recommend it to be merged before

[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.
