Getting started

Components running on X11 graphics backend are based on Xlib with libX11.so library for the communication with Xorg server, and twm window manager is started.

Note that components running on X11 graphics backend can also be based on XCB with libxcb.so library for the communication with Xorg server.

If the current graphics backend used on HiGFXback is not X11, switch on it with startx11 command. Select one of the following graphics driver interface available on HiGFXback and used by Xorg server for the display:

• Linux Framebuffer interface (/dev/fb0) handled with fbdev_drv.so plugin
• KMS/DRM interface (/dev/dri/card0) handled with modesetting_drv.so plugin

But depending on the platform, it’s possible to use specific graphics driver interfaces, possibly with hardware accelerated graphic rendering support, based on the Xorg Device Dependent X (DDX) module architecture.

When starting on X11 graphics backend with startx11 command, select one of the following input driver interface available on HiGFXback and used by Xorg server for managing the keyboard:

• console interface (/dev/tty0) handled with kdb_drv.so plugin
• event device interface (/dev/input/event0) handled with evdev_drv.so plugin

and for managing the mouse:

• PS/2 mouse interface (/dev/psaux) handled with mouse_drv.so plugin
• event device interface (/dev/input/event1) handled with evdev_drv.so plugin

But depending on the input peripheral, it’s possible to use specific input driver interfaces based on the Xorg input module architecture.

xterm

When starting on X11 graphics backend, xterm terminal emulator is displayed. System informations about X11 settings can be get with xdpyinfo.

Vulkan rendering

For display rendering with X11 graphics backend, Vulkan implementation in libvulkan.so library (loading library from Vulkan-Loader) and its ICD (Installable Client Driver) relies on Xlib WSI or XCB WSI interfaces.

On HiGFXback, Xlib WSI or XCB WSI interfaces (Window System Integration for X11) are used with one of the following ICD selected with VK_ICD_FILENAMES environment variable:

• SwiftShader associated to swiftshader_icd.json manifest file
• Kazan associated to kazan_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.
