[PATCH v7] pci: prevent putting nvidia GPUs into lower device states on certain intel bridges
...ell, no? And I know that if the
bus stays in D0, that it has a negative impact on power consumption.
Anyway, I will try that out, I am just not seeing how that would help.

[PATCH v7] pci: prevent putting nvidia GPUs into lower device states on certain intel bridges
...do that with something like the following? I don't know
anything about DRM, so I don't know where you could save the pm_cap,
but I'm sure the driver could keep it somewhere.

[PATCH v7] pci: prevent putting nvidia GPUs into lower device states on certain intel bridges
Fixes the infamous 'runtime PM' bug many users are facing on Laptops with
Nvidia Pascal GPUs by skipping said PCI power state changes on the GPU.
Depending on the used kernel there might be messages like those in demsg:
"nouveau 0000:01:00.0: Refused to change power state, currently in D3"
"nouveau 0000:01:00.0: can't change power state from D3cold to D0 (config

...wed up locally. Will do
some proper testing and then I think we won't need to go through the
pci tree anymore as no changes are required there with that.
