[PATCH v2 0/4] nouveau RPM fixes for Optimus
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).
See the first version[1] for a background on the fixed problems. This is the
second revision of incorporating feedback from Emil Velikov (patch 1), Mika
Westerberg (patch 4).

[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
