Phoronix: AMD Prepares USB-C Linux Driver Support For Radeon Graphics Cards

With some Radeon RX 6000 series graphics cards sporting a USB-C interface for USB-C monitors or VR headsets, AMD has been working on the open-source Linux driver support for this interface...

the end of DVI, DisplayPort and HDMI... usb type c with 40gb/s , RIP DisplayPort...

Please note this USB-C port will probably support more than just monitors and VR headsets.

I don't know myself, but the patch note does state, "The Latest AMD NAVI GPU card has an integrated Type-C controller ... The client driver is part of the USB Type-C UCSI driver". The Linux UCSI driver exposes all the type-c port capabilities the particular hardware can deal with - xfr speeds, power delivery, etc.

The same port on Nvidia drivers worked with usb flash drives, usb hubs, network dongles, smartphones, headphones, and even adapters to other monitor connections. https://www.eurogamer.net/articles/d...nt-just-for-vr

Funny how they add it even when Nvidia has already dropped it and never even shipped it in quantity.

Great news, I intend to attach a USB floppy drive.

Oh right Valve dropped the VirtualLink for Index too and the Oculus Quest Link works with pretty much all USB-C ports that come integrated in motherboards these days.

Seems kinda useless with how things are going. Still nice to have I guess.

How is it with Dockingstations for Notebooks. They have display output over USB-C and PD charge the battery.
If you now buy a AMD APU Notebook, it would be great...
Or is it still supported?

Normally, I think most of the ideas surrounding USB-C are really stupid in the long term, but since it has already been established, I think having a single cable for a VR headset is a great idea. Power, audio, video, and sensor data all delivered through 1 manageable cable. A HDMI cable alone is often thicker than USB-C.
I don't really get why Nvidia abandoned the port so quickly, especially seeing as USB-C is basically the new DP form factor.

My guess would be signal integrity problems over long runs. I have a Valve Index and it has a proprietary "one cable" that carries power from a brick, DP and USB3. From what I can tell it's quite special because it has a detachable part with a weird connector. Said connector gets warm during use which leads me to believe there's an active repeater/amplifier in it.
The cable can be detached from the headset and has a plug going into the splitter/amplifier part. Valve apparently wanted to make a VirtualLink one, but it got cancelled over technical issues.
Other vendors probably faced similar fate.
