I guess you are referring to pci_save_pcie_state(). I can't see
anything equivalent for the bridge registers.

I agree. There's a definite difference with W...

Rewriting Intel PCI bridge prefetch base address bits solves nvidia graphics issues
Hi,
We are facing a suspend/resume problem with many different Asus laptop
models (30+ products) with Intel chipsets (multiple generations) and
nvidia GPUs (several different ones). Reproducers include:
1. Boot
2. Suspend/resume
3. Load nouveau driver
4. Start X
5. Observe slow X startup and many many errors in logs (primarily
nouveau fifo faults)
or
1. Boot
2. Load nouveau driver
3. Start X
