Bug description:
[SRU Justification]
[Impact]
When the ADL-P system connects the external display via TypeC port, it will
hang after unplugging the TypeC connector. The system will never come back
until reboot.
[Fix]
Intel has released a patch set to fix the TypeC PHY connect/disconnect logic.
The shift for ownership of PHY and power domain will be handled correctly for
ADL-P.
[Test]
The ADL-P system will no longer freeze and the ownership will shift correctly
after disconnecting the external display connects via TypeC port.
[Where problem could occur]
It's kind of a big refactor for the i915 TypeC PHY handling logic. Don't know
if there's any problems on older platforms. Targeting only on Unstable and
latest OEM kernel for lower risk.
================== Original Bug Description ======================
[Summary]
The system will hang on after unplug DA310 with external monitor (on-demand)
Note:
1. Build-in HDMI port cannot duplicate.
2. VGA/HDMI/DP on DA310 to system all can duplicate.
3. Unplug VGA/DP/HDMI from DA310, then unplug DA310 from the system cannot
duplicate.
[Steps to reproduce]
1. Install dell-bto-focal-fossa-pypar-adl-X160-20210923-2.iso
2. Plug DA310 to USB-C port
3. Plug DP/VGA/HDMI to DA310
4. Unplug DA310 > The system hangs on with black screen
[Expected result]
The system works well after unplug USB-C with external monitor
[Actual result]
The system hangs on blackscreen after unplug DA310 with external monitor
[Failure rate]
3/3
