Intel supports helping Linux systems implement USB-C interface DP 2.1 display connection

According to the latest reports, Intel’s open source Linux engineers are working on adding support for DisplayPort 2.1 to Linux systems

According to our understanding, Intel engineers submitted a series of Linux kernel patches last Friday. to enable the cable identification process and ensure that DisplayPort on the USB-C interface Alternate Mode 2.1 functionality. Meanwhile, the code for the Chrome cros_ec_typec driver has also been tweaked, suggesting Intel may be eyeing the addition of DP Alt Mode 2.1 extends to the Chromebooks it drives

The introduction of DisplayPort Alternate Mode 2.1 is an important improvement that requires the Type-C driver to configure reporting regarding signaling, UHBR13.5, cable type, and DPAM version Additional cable details. The introduction of this new feature provides users with a better connection experience and high-quality multimedia transmission

The released DisplayPort 2.1 not only enhances the compatibility with the USB Type-C specification and The consistency of the USB4 PHY specification also introduces new bandwidth management capabilities, allowing DisplayPort tunnels to work more efficiently with other I/O data traffic to transmit data over the USB4 link. In addition, DisplayPort 2.1 also updates the cable specification to provide greater robustness and enhancements, extending cable lengths without affecting performance

Currently, this patch series is under review and has not yet been merged to the Linux kernel. As these improvements continue to be improved, we believe that users will soon be able to experience the advanced features of DisplayPort 2.1 in Linux systems. The editor will continue to pay attention to the development of this topic and provide readers with more latest updates on DisplayPort technology
