New Linux graphics kernel patches with USB4 DisplayPort Tunneling are now available from AMD. The tunneling feature allows the USB, DisplayPort and PCIe transfer protocols to operate simultaneously by sharing the available bandwidth. For now, only the DisplayPort 1.4 specs are supported with AMD’s tunneling drivers. Hopefully, DisplayPort 2.0 specs could be added by the time AMD introduces its next gen embedded and laptop solutions in early 2022.
