There's a series queued up for 4.10 which will suspend hotplug ports to D3hot when nothing is connected. I cc'ed Keith when I posted it, but I forgot to cc you: https://www.spinics.net/lists/linux-pci/msg55564.html If you haven't tested this series so far, now would be a good time to do so, as it would allow fixing regressions (if any) before 4.10 is out. Note that this series might save you quite a bit of power if you have lots of unused ports. You can fetch the patches from: https://github.com/l1k/linux/commits/pcie_port_pm_v2 Thanks, Lukas -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
