[Bug 2045621] Re: Improve power consumption on Framework systems

[Steve Langasek]

Hello Artur, or anyone else affected,

Accepted systemd-hwe into mantic-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/systemd-
hwe/253.5.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
mantic to verification-done-mantic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-mantic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [ Impact ]

   * Framework systems that have DP or HDMI cards connected will have
  increased power consumption even when nothing is connected to DP or
  HDMI ports since the cards don't default to autosuspend.

   * Backporting upstream patch that adds rules in
  hwdb.d/60-autosuspend.hwdb for Framework's HDMI and DP extensions.

  [ Test Plan ]

   * DUT: Framework with DP and HDMI:

  $ lsusb | grep Framework
  Bus 007 Device 002: ID 32ac:0003 Framework DisplayPort Expansion Card
  Bus 001 Device 002: ID 32ac:0002 Framework HDMI Expansion Card

   1. Autosuspend is not enabled before patch. Set to "on" in
  power/control

  $ cat /sys/devices/pci0000:00/0000:00:08.1/0000:c1:00.3/usb1/1-1/manufacturer
  Framework
  $ cat /sys/devices/pci0000:00/0000:00:08.1/0000:c1:00.3/usb1/1-1/power/control
  on

  $ cat /sys/devices/pci0000:00/0000:00:08.1/0000:c1:00.3/usb1/1-2/manufacturer
  Framework
  $ cat /sys/devices/pci0000:00/0000:00:08.1/0000:c1:00.3/usb1/1-2/power/control
  on

   2. Install patch
   3. Autosuspend is enabled for both extensions. Set to "auto" in power/control

  $ cat power/control
  auto

  [ Where problems could occur ]

   * During testing verified that both DP+HDMI display show good output after hot-plug, system suspend, and reboot. There might be some differences when hibernate and hotplug.
