Is alt-dp mode over USB-C working for anyone else using megi's 6.9 kernel?
For a long time I stayed on a 5.7 kernel I got somewhere, and the alt-dp just worked. Yesterday, I "upgraded" to Manjaro's linux 6.7.9-1 and found that it no longer works. Manjaro linux-lts (6.1.81-1) also doesn't support it.
https://xff.cz/kernels/ only has 6.9 now, and I see it mentioned in the changelog,
But it doesn't actually work. dmesg:
EDIT: Uni Accessories USB-C to DisplayPort Cable is working. Bizlink is not. On the old kernel they both did. Also running into two unrelated features that work on 6.7.9-1-MANJARO-ARM but not on megi 6.9.0-00566-g6be698fa4d94 because they weren't compiled in. Time to email.
Edit 2: All fixed in the 6.12 build.

- rebased and ported everything to v6.9
- fix alt-dp mode on Pinephone Pro and Pinenook Pro, it was not being entered
due to https://lore.kernel.org/lkml/20231204020...inaro.org/
