Looks like I'm trying to get Wayland running in Nokia N900. Is there any
experiences about that already? All help and estimations about work
amount is welcome.
Hi,
I don't know that anybody has tried that. The big unknown is how to
integrate with the graphics drivers on the device - the GL stack and
modesetting. And the GL stack has to provide a way for processes to
share 2d pixel buffers (for example an EGLImage). I've never worked
with the n900 platform, so I don't know, but a good first step towards
Wayland would be to try to run EGL+GLES2 on the framebuffer or such.
You can run the graphics stack on N900 on the framebuffer without X, but the
problem is there's no way to share EGLImages across processes in that
configuration. That is, the graphics driver does not support
EGL_MESA_drm_image or any equivalent.
With X, sharing EGLImages between processes is possible by backing them with
pixmaps. So in theory you could run Wayland on N900 by using X for resource
management -- but that would mostly defeat the purpose.

Doomed right in the start :( Need to find some other topic for thesis
work then if this is impossible..
