A new kernel is out the door, Linux 5.11, and it brings many goodies and better hardware support. Collabora is well known for their awesome contributions to the Linux kernel, and this cycle they continued to improve support for Chromebooks and modern Windows gaming.
First, the good news for Linux gamers as Collabora introduced a new interface that more efficiently intercepts, filters and emulates system calls in the Linux kernel, called Syscall User Dispatch. While all this might sound boring, it's not. Once configured, Syscall User Dispatch is entirely controlled from user space to enable Windows compatibility layers like Wine or Valve's Proton to better support modern Windows gaming in Linux.
