[RFC 0/9] gbm_surface

[Ander Conselvan de Oliveira]

From: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira at intel.com>

Hi,

So, in London we discussed moving the drm compositor to a new
gbm_surface interface, which would allow the buffer management
to be handled by the egl implementation by calling eglSwapBuffers.

Here's a prototype implementation of such an interface in mesa and a
patch to wayland-demos moving compositor-drm to it. With the changes,
the compositor creates a gbm_surface for each output and from that it
creates egl surfaces.

The compositor is still responsible for the actual flipping. In order
to do that, the new interface includes a function for getting a bo for
a gbm_surface's front buffer. This change does not impact the ability
of scanning out a client buffer.

Thanks,
Ander
