[fedora-arm] Re: Questions to Fedora on Pinebook Pro

Hi,

It's not related to the firmware, it's not supported in the upstream
kernel. It comes down to how the HW implements the various "Alt"
options for USB-C and there needs to be work done on the rockchip
"USB-C multiplexer" driver that switches the functionality. When it
lands upstream it'll just work but I'm not aware of anyone actually
doing to work to get that upstream. There's been a bunch of hacks but
nothing that's maintainable upstream.

What desktop or compositor? Need more details.

There's work needed on the Alsa UCM2 profiles here, there has been
some upstream work that has landed in Fedora but it didn't work for me
either, I've not had time to further investigate/debug this and the
documentation on how the alsa UCM profile stuff works is poor to say
the least and I'm not had time to dig deeper. Assistance is welcome
here.
