Linux 5.6 will receive support for USB4, Phoronix (opens in new tab)reported on Sunday. The Linux 5.6 Kernel will likely debut by April.
USB4’s spec (opens in new tab) published in September and is based on Thunderbolt 3, with which it is backwards compatible. Intel's open-source department added the initial patches for USB4 (opens in new tab) in October.
The Linux 5.6 kernel will reportedly have both host and device support, as well as source code and a bunch of other features, thanks to leveraging the existing Thunderbolt code. It has also kept the code compact at just 2,000 lines of code.
Other new features in Linux 5.6 include Intel Shared Virtual Memory (opens in new tab), which will be used by the upcoming Intel Xe GPUs, and support for the WireGuard (opens in new tab) VPN protocol.
