Add comments to help explain why the code in pci_bridge_d3_possible() doesn't match the spec (we disallow D3 for conventional PCI bridges and for hotplug bridges, and the spec seems to suggest that D3 could work in both of those situations).
Make "pcie_port_pm=force" and "pcie_port_pm=off" apply to all PCI bridges including conventional PCI bridges and hotplug bridges. This is a little speculative. Those parameters are risky to begin with (otherwise "pcie_port_pm=force" would be the default); this would make them more general-purpose but obviously also even more risky. --- Bjorn Helgaas (2): PCI: Add PCIe port runtime suspend details PCI: Allow user to request power management of conventional and hotplug bridges Documentation/admin-guide/kernel-parameters.txt | 8 ++--- drivers/pci/pci.c | 40 +++++++++++++++++------ 2 files changed, 34 insertions(+), 14 deletions(-)
