From: "Chia-Lin Kao (AceLan)" <acelan.kao@canonical.com> BugLink: https://bugs.launchpad.net/bugs/1955016 [Impact] When booting up with the TBT dock is plugged, the devices(USB, Ethernet) on the dock can't be recognized. It requires to run lspci command to wake up the PCI devices to make the devices on the dock work. [Fix] The patchset fix this runtime pm issue. https://patchwork.kernel.org/project/linux-usb/cover/20211125073733.74902-1-mika.westerberg@linux.intel.com/ [Test] Verified on Dell ADL-P platform with TBT dock. [Where the problems could occur] Hard to evaluate, but after some cold boot/warm boot, plug/un-plug the devices on the dock, didn't observe any regressions. Mika Westerberg (6): thunderbolt: Runtime PM activate both ends of the device link thunderbolt: Tear down existing tunnels when resuming from hibernate thunderbolt: Runtime resume USB4 port when retimers are scanned thunderbolt: Do not allow subtracting more NFC credits than configured thunderbolt: Do not program path HopIDs for USB4 routers thunderbolt: Add debug logging of DisplayPort resource allocation drivers/thunderbolt/acpi.c | 13 +++++++ drivers/thunderbolt/path.c | 42 +++++++++++++--------- drivers/thunderbolt/retimer.c | 28 +++++++++------ drivers/thunderbolt/switch.c | 27 ++++++++++++-- drivers/thunderbolt/tb.c | 68 ++++++++++++++++++++++++++--------- drivers/thunderbolt/tb.h | 5 ++- drivers/thunderbolt/tunnel.c | 27 ++++++++------ drivers/thunderbolt/tunnel.h | 9 +++-- 8 files changed, 159 insertions(+), 60 deletions(-)
