The pcieport driver defines runtime_suspend and runtime_resume methods (pcie_port_runtime_suspend/resume in portdrv_pci.c). I am trying to trigger that code. But I cannot get power/runtime_usage to drop to zero. Initially power/runtime_usage is set to 2. The 2 comes (imho) from: pci_pm_init -> pm_runtime_forbid local_pci_probe -> pm_runtime_get_sync The pm_runtime_forbid can be undone with echo auto > power/control, but the second one seems to never go away. local_pci_probe spots the following comment: "If the driver supports runtime PM, it should call pm_runtime_put_noidle() in its probe routine and pm_runtime_get_noresume() in its remove routine." I cannot find any such calls in the pcieport driver (or in the port service drivers). What am I missing?
