After dig more about async threads, I found dpm_prepare/complete phases need them also.
dpm_prepare() -- > call pci_pm_prepare() one by one -- > call pm_runtime_resume() one by one -- > call pci_set_power_state to D3HOT -- > D0
It will cause much time delaying due to d3_delay. And I made one draft patch to implement the asynchronous threads for dpm_prepare(), it is really save much time.
If you like it, I can prepare another series patches for dpm_prepare() and dpm_complete(), thanks.
Best Regards,
