...A) it sets "SGFL" (Switchable Graphics FLags?), on others it has no side-effects but returns a value based on Arg3 (Clevo P155M). A Medion P7624 stores values to "OPTF" (OPTimus Flags?) and if this flag is true, \_SB.PCI0.PEG0.PEGP._ON will write zero to "NHDM". While NOUVEAU_DSM_HAS_OPT is removed from this patch, I kept the flags return value which can be useful for other probe outcomes (such as whether _PR3 is found on the parent device).

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).

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: https://bugzilla.kernel.org/show_bug.cgi?id=104791#c11 (it is replaced by "check for function 0x1B

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
