similar to: [PATCH] acpi: allow non-optimus setups to load vbios from acpi

Hi, same for me. The screen does not freeze anymore and the boot succeeds. But now I have this kernel message during boot (for the second card): [ 24.382045] pci_pm_runtime_suspend(): nouveau_pmops_runtime_suspend+0x0/0xe0 [nouveau] returns -22 Do you want to have the complete dmesg log? I think this is a new bug. Your patch works for the previous one, so you can close it. Yours, Claas On

This is especially true when variables or functions are just called dsm without precising the v1.

I have tested this patch. I can confirm that now nouveau loads correctly without errors.

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

Do not unconditionally invoke function 0x1B without checking for its availability, it leads to an infinite loop on some firmware.

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.

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

Replace nouveau_pr3_present() in favor of a more generic one, pci_pr3_present(). Also the presence of upstream bridge _PR3 doesn't need to go hand in hand with device's _DSM, so check _PR3 before _DSM.

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
