Hi,

While this may just be connecting the dots, I am not able to fully
understand how pci_save_state works.

I see that the pci_save_state and pci_restore_state are invoked at
suspend and resume. ?This saves the PCI configuration registers during
suspend. Are these the device registers or bridge registers?

It depends if the device is a device or a bridge :)

Consequently, is the pci_save_state and driver suspend routine saving
the full device state/device state exposed to PCI or PCI state ?

Yes.

Hope this helps,
