What are these "certain scenarios"? There are already "d3hot_delay" and "d3cold_delay" members in struct pci_dev. I'm wondering if it would make sense to add another one, say, "flr_delay". That would allow other devices to reduce or lengthen the delay without each of them having to duplicate pcie_flr(). The code duplication makes this difficult to maintain long-term. Thanks, Lukas
