Getting started

Components running on Wayland graphics backend are based on libwayland-client.so library for the communication with weston, the Wayland compositor.

If the current graphics backend used on HiGFXback is not Wayland, switch on it with startwl command. Select one of the following graphics driver interface available on HiGFXback and used by weston for the display:

• Linux Framebuffer interface (/dev/fb0) with weston fbdev-backend.so plugin
• KMS/DRM interface with (/dev/dri/card0) weston drm-backend.so plugin

But depending on the platform, it's possible to use specific graphics driver interfaces based on the weston backend module architecture.

Keyboard and mouse are managed by weston with libinput.so library which provides a generic input abstraction layer of the event device input driver interface (/dev/input/event0 and /dev/input/event1) available on HiGFXback.

weston-terminal

When starting on Wayland graphics backend, weston-terminal terminal emulator is displayed. System informations about Wayland settings can be get with weston-info.

Vulkan rendering

For display rendering with Wayland graphics backend, Vulkan implementation in libvulkan.so library (loading library from Vulkan-Loader) and its ICD (Installable Client Driver) relies on Wayland WSI interface.

On HiGFXback, Wayland WSI interfaces (Window System Integration for Wayland) are used with one of the following ICD selected with VK_ICD_FILENAMES environment variable:

• Mesa associated to lvp_icd.json manifest file
• SwiftShader associated to swiftshader_icd.json manifest file

But depending on the platform, specific ICD can be used.

Vulkan-Tools, Vulkan-Examples, vkcube2 and yagears2 programs are available as examples, tests or benchmarks.

OpenGL rendering

For display rendering with Wayland graphics backend, OpenGL implementation in libGL.so library, but also OpenGL ES 1.1 CM implementation in libGLESv1_CM.so library and OpenGL ES 2.0 implementation in libGLESv2.so library, rely on EGL for Wayland interface.

Loading libraries can be used:

• libGLEW.so library from GLEW (OpenGL Extension Wrangler)
• libepoxy.so library from Epoxy

On HiGFXback, EGL for Wayland interfaces are used with one of the following implementation selected with alternatives-GL command:

• Mesa with libEGL.so -> libmesaEGL.so, libGL.so -> libmesaGL.so, libGLESv1_CM.so -> libmesaGLESv1_CM.so, libGLESv2.so -> libmesaGLESv2.so libraries
• SwiftShader with libEGL.so -> libswiftshaderEGL.so, libGLESv1_CM.so -> libswiftshaderGLESv1_CM.so, libGLESv2.so -> libswiftshaderGLESv2.so libraries

But depending on the platform, specific implementation can be used.

mesa-demos and yagears programs are available as examples, tests or benchmarks.

User interface toolkits

GTK+

Graphical user interfaces can rely on GTK+ (Gimp ToolKit) using the port for Wayland graphics backend. Web rendering can then rely on WebKitGTK+, a port of the WebKit browser engine for GTK+.

On HiGFXback, GTK+ interfaces running on Wayland graphics backend are provided by libgtk-3.0.so library (which also integrates OpenGL rendering interfaces).

gtk-demo, gtk-tests, gtkperf and yagears programs are available as examples, tests or benchmarks.

On HiGFXback, WebKitGTK+ interfaces for GTK+ with Wayland graphics backend are provided by libwebkitgtk-3.0.so library.

GtkLauncher program is available as example.

Qt

Graphical user interfaces can rely on Qt (Q toolKit) using the port for Wayland graphics backend. Web rendering can then rely on QtWebKit, a port of the WebKit browser engine for Qt.

On HiGFXback, Qt interfaces running on Wayland graphics backend are provided by libQt5Gui.so and libQt5OpenGL.so libraries.

qtdemo, qt-examples, qtperf and yagears programs are available as examples, tests or benchmarks.

On HiGFXback, QtWebKit interfaces for Qt with Wayland graphics backend are provided by libQt5WebKit.so library.

QtTestBrowser program is available as example.
