Wayland's Weston compositor can run on a wider range of systems with the yet-to-be-merged patches providing integration to run the display system on any DirectFB-enabled platform with OpenGL ES acceleration and without needing any vendor-specific hardware extensions.
A few weeks back I wrote about the initial work done for letting Wayland's Weston run on DirectFB
and the DirectFB developers drawing up really great plans for the future
. Now these developers are out with an updated patch-set for the Weston DirectFB integration support.
Spread across six patches and adding almost 4,000 lines of new code to Weston, the changes allow for the Wayland compositor to work on any DirectFB-enabled platform with optional OpenGL ES support via EGL where there is an EGL/GLES driver. The Wayland extensions in EGL United are implemented in a generic module and require no vendor-specific Wayland extensions in order to be supported. This DirectFB back-end also supports using the Pixman renderer when EGL / OpenGL ES support isn't exposed.
See the two earlier articles for more details if you missed them or hit up the Wayland-devel list
for these latest patches.
