Add support for getting hardware presentation times from KMS (Wayland sessions). Also implement cogl_get_clock_time which is required to compare and judge the age of presentation timestamps. For single monitor systems this is straightforward. For multi-monitor systems though we have to choose a display to sync to. The compositor already partially solves this for us in the case of only one display updating because it will only use the subset of monitors that are changing. In the case of multiple monitors consuming the same frame concurrently however, we choose the fastest one (in use at the time). Note however that we also need !73 to land in order to fully realize multiple monitors running at full speed. |

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
