...owerdown and update the current_state to D3cold. On powerup the PCI device itself and the hierarchy below it is in D0uninitialized, so we need to walk the hierarchy again and wake all devices, causing them to be put into D0active and then letting them autosuspend as they see fit. To this end make pci_wakeup_bus() & pci_bus_set_current_state() public so PCI drivers don't have to reinvent the wheel. Cc: Bjorn Helgaas <bhelgaas at google.com> Cc: Rafael J.

...actions in pci_pm_runtime_resume(), see patch [1/7]. This all looks really reasonable and like a good cleanup, but it's a bit too much detail so I'll punt review to someone else with more clue. -Daniel > > Thanks, > > Lukas > > > Lukas Wunner (6): > PCI: Make pci_wakeup_bus() & pci_bus_set_current_state() public > vga_switcheroo: Update PCI current_state on power change > vga_switcheroo: Deduplicate power state tracking > vga_switcheroo: Use device link for HDA controller > vga_switcheroo: Let HDA autosuspend on mux change > drm/nouveau: R...
