Previously the only requirement for the IRQ was that it be an unsigned integer. Zero is an unsigned integer but an invalid IRQ number,...

[PATCH v3] pci: prevent putting nvidia GPUs into lower device states on certain intel bridges
but setting the PCI_DEV_FLAGS_NO_D3 flag does prevent using the platform means of putting the device into D3cold, right? That's actually what should still happen, just the D3hot step should be skipped.

[PATCH] PCI: stop spamming info in quirk_nvidia_hda
...the controller after runtime suspend? Maybe this should be a pci_info_once() sort of thing? I think there's some value in knowing that we're changing the BIOS configuration outside the purview of a driver, since I assume BIOS had some reason for hiding the HDA controller. > Cc: Bjorn Helgaas <bhelgaas at google.com> > Cc: Lukas Wunner <lukas at wunner.de> > Cc: linux-pci at vger.kernel.org > Cc: nouveau at lists.freedesktop.org > Fixes: b516ea586d71 ("PCI: Enable NVIDIA HDA controllers") > Signed-off-by: Karol Herbst <kherbst at redhat.com> &g...
