System works fine without whatever it's > trying to do (of course, since it wasn't even detected before :-) ) Hi Chris, I lit up the code in GENERIC in 886164895f — so that’s my fault :) (any info about the thunderbolt devices would be appreciated!). obiwac@ asked that I back it out, so I’ll take care of that now since it’s on my mind. Thanks! -Enji PS The thunderbolt(4) device implementation is incomplete: it was based on work done by hselasky@ before he passed away back in 2023. I have a TODO item to look at trying and get it working (enough) to have functional Thunderbolt/USB4 stack for storage purposes, but it’s way down my TODO list. tl;dr: I’m trying to get a partially functional Mac x86 port before Apple nukes Intel support from macOS.
