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). 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). 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

From: Sui Jingfeng <suijingfeng at loongson.cn> There is no function that can be used to get all PCI(e) devices in a system by matching against its the PCI base class code only, while keep the sub-class code and the programming interface ignored. Therefore, add the pci_get_base_class() function to suit the need. For example, if an application want to process all PCI(e) display devices in a
