For the implementation of fifo-v1, we need to be able to track the presentation of individual surface commits. This is done already in `wlr_presentation_time`, but the way that is implemented is suited only for use by clients through the protocol interface (.feedback requests). Here we use the `surface_output` structure, which is a low-level structure that links wlr_surfaces with wlr_outputs. Within this structure we listen to the surface's and the output's .commit events. Through these 2 we link a surface commit to an output commit. Then, a new struct wlr_surface_output_commit is created which listens to the output's .present event. For the interface to this functionality, 2 elements are introduced: the new .present event in struct wlr_surface_output, which signals listeners whether a particular pair of (surface_seq, output_seq) has been presented or discarded, and the wlr_surface_textured_on_output() function, used by the scene logic to inform the implementation that the surface's buffer has been textured on a particular output.

wlroots
Pluggable, composable, unopinionated modules for building a Wayland compositor; or about 60,000 lines of code you were going to write anyway.
- wlroots provides backends that abstract the underlying display and input hardware, including KMS/DRM, libinput, Wayland, X11, and headless backends, plus any custom backends you choose to write, which can all be created or destroyed at runtime and used in concert with each other.
- wlroots provides unopinionated, mostly standalone implementations of many Wayland interfaces, both from wayland.xml and various protocol extensions. We also promote the standardization of portable extensions across many compositors.
- wlroots provides several powerful, standalone, and optional tools that implement components common to many compositors, such as the arrangement of outputs in physical space.
- wlroots provides an Xwayland abstraction that allows you to have excellent Xwayland support without worrying about writing your own X11 window manager on top of writing your compositor.
- wlroots provides a renderer abstraction that simple compositors can use to avoid writing GL code directly, but which steps out of the way when your needs demand custom rendering code.
wlroots implements a huge variety of Wayland compositor features and implements them right, so you can focus on the features that make your compositor unique. By using wlroots, you get high performance, excellent hardware compatibility, broad support for many wayland interfaces, and comfortable development tools - or any subset of these features you like, because all of them work independently of one another and freely compose with anything you want to implement yourself.
Check out our wiki to get started with wlroots. Join our IRC channel: #wlroots on Libera Chat.
A variety of wrapper libraries are available for using it with your favorite programming language.
Building
Install dependencies:
