Intel submits preliminary USB4 Version 2.0 support for Linux 6.5
July 4 news, last September, the USB Promoter Group announced the USB4 Version 2.0 standard, which can use USB-C data cables to achieve up to 80 Gbps (10GB/s) transmission speed and can handle 120 Gbps of data in one direction and 40 Gbps of data in the other direction.
Intel has now provided initial support for USB4 v2 in the Linux 6.5 kernel with initial enablement on its new Intel Barlow Ridge controllers.
Intel engineer Mika Westerberg worked on the launch of USB4 v2 along with numerous Linux engineers and enabled their Barlow Ridge controllers.
Initial support includes 80G symmetric link support, number of bits required to boot router in v2 mode, adaptive TMU processing, PCIe extended encapsulation, DisplayPort 2.x tunnel support, and CL2 Low-power link state handling, 120G and 80G link support, and other changes are coming.
In addition to these patches, IT House has not found much information about Intel Barlow Ridge, which seems to be Intel’s upcoming USB v2 dedicated controller.
It is reported that USB4 v2 support for Linux is part of the USB pull request for Linux 6.5, which also adds a new Qualcomm PMIC Type-C driver, NVIDIA Tegra stream protocol support, and CDNS2 device driver and many other updates.
