I&#39;ve finally just submitted the RFC series for USB3 support on Apple Silicon machines. RFC because the entire Type-C machinery spans multiple subsystems and has quite a few quirks which makes the entire thing rather annoying to deal with and I&#39;m not 100% convinced about the current approach. This also includes some initial work for DisplayPort-altmode and USB4/Thunderbolt but both will require much more work after this is upstream, so don&#39;t get your hopes up just yet. https://lore.kernel.org/asahi/20250821-atcphy-6-17-v1-0-172beda182b8@kernel.org/ #asahilinux #linux

@sven Nearly 4000 lines of code, what an absolute monster of a patch series. Thank you for the years of hard work on this project.

@sven Is the bring up sequence and trickery with DWC3 also present on MacOS/Xen? More specifically, I'm curious if MacOS also needs to power cycle DWC3 on connection events or if they do something else. That seems like a really odd design choice. ;)

@sven @AsahiLinux I don’t understand most of the tech here, but I think this is a step towards USB-C screens? I’m very excited for that. Even if it’s not, I really appreciate your efforts!
