Mainboard
Discontinued Documentation for the Mainboard and other modules in the Framework Laptop 13 [Moved to: https://github.com/FrameworkComputer/Framework-Laptop-13]
Interesting. Do we have a concrete reason why, e.g., TLP[0] falls short of the power management features offered on other OSes?

My Arch on Framework experience has been great. If you're just getting yours up and running, I've been keeping notes on tuning/setup: https://github.com/lhl/linuxlaptops/wiki/2022-Framework-Lapt...
Some people have been getting hard graphics lockups (seems to be an Intel 12th-gen GPU / GNOME issue that may be affecting more than just the Frameworks). I'm running Sway and have yet to have any lockups over a month and a half of usage, though. Here's the community discussion thread: https://community.frame.work/t/hard-freezing-on-fedora-36-wi...
One thing worth noting is that basically, even now (almost 10 months post announcement), almost no one has a 6000U laptop outs (a search on Amazon and Best Buy shows two 6800U laptop models total, one Asus and one Lenovo). Two niche vendors, XMG and Star Labs, have both publicly stated that they would have loved to have offered Ryzen 6000 laptops, but couldn't get any allotments. There are were also well documented chipset issues - even into the summer Lenovo and Asus talked about requiring firmware updates to enable their USB4 ports.
That being said, starting w/ Rembrandt, AMD now has full 40Gbps USB4 controllers built on-chip. I'm really looking forward to Ryzen 7040 because Phoenix looks great (Zen4 + RDNA3 on TSMC N4 - yes please) and hopefully USB4 support has matured enough on the AMD side that Framework is able to release something.
My understanding is that the I/O limitation is in the re-timers - currently the Framework uses 4X JHL8040R's (labeled as Burnside Bridge) directly connected to the iTBT: https://github.com/FrameworkComputer/Mainboard/blob/main/Ele... Apple used these for their first M1 MBAs as well: https://github.com/ThomasKaiser/Knowledge/blob/master/articl...
But both Apple and AMD are now using Kandou retimers:
