The State Of Killing CONFIG_VT, Moving To User-Space
David Herrmann is a student developer and one of the kernel developers that has been on a mission to kill off CONFIG_VT, a.k.a. the VT console within the Linux kernel, and move it off to user-space. He's contributed to various projects to further his ideas and now he's written a new post to provide an update on this matter and his thoughts on the current situation of Linux system compositors.
For those interested in Linux graphics, system compositors, and low-level Linux technical reading, Thoughts on Linux System Compositors by David is worth reading. His blog post covers virtual terminals, systemd, current problems, logind, limitations, quirks, the Wayland System Compositor, the Kernel Log driver, and much more.
For those wanting to skip all of the low-level details, Herrmann concludes his post with:
While I was an enthusiastic advocate of the system-compositor idea, it did become pretty clear, that the performance penalty for input-event forwarding and the huge required kernel API extensions make it very unlikely that it will get accepted in the community. Furthermore, besides global keyboard handling, most technical concerns on the logind idea can be solved with quirks like wlsystemc and uvtd.
David Herrmann is the student developer currently working on DRM render nodes through the Google Summer of Code and he's also been responsible for SimpleDRM, FBLOG, and numerous other interesting open-source code contributions.
