A modular Wayland compositor library with EGLStreams support

Primary LanguageCMIT LicenseMIT

wlroots-eglstreams - NVidia EGLStreams support for popular wayland compositor library!

Supported:

Add EGLStreams support for DRM backend

Supported:
1. Damage tracking
2. EGLStreams buffer allocator
3. DMA-BUF mostly works
4. VT switching, sleep/wakeup restoring
5. Client's wayland GL texture import
6. Multi-out

Known issues
1. Multi-GPU support not tested

TIP: run mozilla with MOZ_ENABLE_WAYLAND=1 and MOZ_WEBRENDER=0,

This repo also contains implementation of xwayland_keyboard_grab_unstable_v1 protocol.

NOTE This repo is to be constantly rebased upon original wlroots. Be sure before a rebuild to update your local copy either by recloning or:

cd wlroots-eglstreams
git fetch
git reset --hard origin/master

Rebuild and reinstall sway if using it.

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.

Building

Install dependencies:

  • meson
  • wayland
  • wayland-protocols
  • EGL and GLESv2 (optional, for the GLES2 renderer)
  • Vulkan loader, headers and glslang (optional, for the Vulkan renderer)
  • libdrm
  • GBM (optional, for the GBM allocator)
  • libinput (optional, for the libinput backend)
  • xkbcommon
  • udev
  • pixman
  • libseat

If you choose to enable X11 support:

  • xwayland (build-time only, optional at runtime)
  • libxcb
  • libxcb-render-util
  • libxcb-wm
  • libxcb-errors (optional, for improved error reporting)

Run these commands:

meson build/
ninja -C build/

Install like so:

sudo ninja -C build/ install
