Hi Jani,
thanks for the offer :-)
[1] is solved in the meantime and it turned out not to be a kernel bug
at all, my patch was aiming at the wrong layer.
Imre was right from the beginning and pointed me in the right
direction.
The real bug is in KWin: on a sink disconnect it keeps the output
enabled and never commits the disable, which is what left the TC PHY
wedged (the no-signal state with all the VMM7100 dongles and the TB4
dock).
I have a KWin fix running here that I can confirm resolves the issue
entirely, verified across all the scenarios that used to trigger the
wedge, and I will submit it as a merge request to KWin.
So please consider [1] withdrawn.
The patches you meant are now on the lists:
[2] drm/i915/dp: Fix FRL rate selection and deep color for HDMI sinks
behind FRL PCONs
https://lore.kernel.org/r/[email protected]
[3] drm/dp: Avoid RBR on Synaptics VMM7100 PCONs failing channel EQ
https://lore.kernel.org/r/[email protected]
[4] drm/dp: Read the PCON max FRL bandwidth only for HDMI DFPs
https://lore.kernel.org/r/[email protected]
[5] drm/dp: Service the CEC tunneling IRQ flags without CEC_IRQ in ESI1
https://lore.kernel.org/r/[email protected]
There is also an unrelated ALSA fix from the same machine:
[6] ALSA: hda/hdmi: disable KAE for Intel Panther Lake
https://lore.kernel.org/r/[email protected]
If something in there is not correct to spec, I am glad about a
pointer in the right direction.
Which ones you let through CI I leave to you.
Thanks a lot!
Alexander
