...'s intervention, we can't fix this problem from nouveau itself. We have to fix it as early as possible in the boot sequence in order to make sure that the GPU is in a clean state before it has a chance to spam us with interrupts and break things. So to do this, we add a new pci quirk using DECLARE_PCI_FIXUP_CLASS_FINAL that will be invoked before the PCI probe at boot finishes. From there, we check to make sure that this is indeed the specific P50 variant of this GPU. We also make sure that the GPU PCI device is advertising NoReset- in order to prevent us from trying to reset the GPU when the machine is in Dedi...
