Most backends relies on gettimeofday(2) for output repaint timestamps but this is not a requirement. Before this patch repaints coming from idle_repaint() always used gettimeofday(2) for timestamps. For backends not using that time source this could cause large jumps between timestamps. To fix this, timestamps needs to always come from the backend. This means that the backend needs to always be responsible of starting the repaint loop in case that the repaint cannot start immediately. The drm backend implementation is from the patch by Ander Conselvan de Oliveira found here: http://lists.freedesktop.org/archives/wayland-devel/2013-February/007393.html Signed-off-by: Jonas Ådahl <jadahl@gmail.com>
Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for buiding weston and its dependencies.
