From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I think the compositor, Mutter in Gnome’s case, has to explicitly request VRR from the display driver via the Wayland protocol. So it’s a bit of each.
There's no Wayland protocol involved, Mutter directly talks to the kernel
Ah, I see, thank you for the correction. Does Wayland only encompass communication between clients and the server? I’ve seen some code calling the wlroots functions for requesting VRR and some of how the Nvidia open kernel modules respond. Is requesting VRR a part of Kernel Mode Setting, then?
Yes
Also yes
Thanks!
