And take it into account in meta_kms_crtc_get_deadline_evasion. This uses the same fundamental approach as clutter frame clock scheduling: Measure the deadline timer dispatch duration, keep track of the longest duration, and set the timer to fire such that the longest measured dispatch duration would result in it completing shortly before start of vblank. Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/3612 v2: * Move DEADLINE_EVASION_CONSTANT_US addition from meta_kms_crtc_determine_deadline to meta_kms_crtc_get_deadline_evasion. * Calculate how long before start of vblank dispatch completed for debug output in crtc_frame_deadline_dispatch. * Shorten over-long lines in crtc_frame_deadline_dispatch. v3: * Take VRR into account in crtc_frame_deadline_dispatch & meta_kms_crtc_update_shortterm_max_dispatch_duration. (Robert Mader) v4: * Check if deadline has already passed in meta_kms_crtc_determine_deadline, set the deadline for one refresh interval later if so. * Fix indentation in crtc_frame_deadline_dispatch.

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 of 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.
