** Description changed: Description: Currently we already support runtime PM for PCIe ports but it is explicitly disabled for hotplug capable ports. There are many reasons for this: 1. It will not work well when ACPI based hotplug is used as the SMI handler will get confused if the port is powered down. 2. For native PCIe hotplug there are problems when the slot is enabled through sysfs like the one here: https://bugzilla.kernel.org/show_bug.cgi?id=193951 Since we are moving from ACPI based hotplug to native PCIe hotplug in case of Thunderbolt, it is essential to get the runtime PM for such ports working properly. We should be able to relax the limitation a bit and allow runtime PM for native PCIe hotplug ports once 2. above has been resolved first. - Target Release: 18.10 + Target Release: 19.04 - Target Kernel: 4.20 + Target Kernel: 4.19 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1741383 Title: [Feature] Runtime PM for native PCIe hotplug ports To manage notifications about this bug go to: https://bugs.launchpad.net/intel/+bug/1741383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
