[PATCH v10 00/61] Atomic modesetting rides again

Hi all,

It looks like the great work proposed by Daniel to have Atomic Modesetting in Weston did not find the success it deserves.
We tested it successfully on STMicroelectronics boards and it works great.

The kernel DRM framework has been reworked in the past months (years) in order to support Atomic, but one of the reference compositor, Weston, does not support this feature.
And as long as this is not supported, there is no way to make use of HW planes ('sprites are broken'): all of the composition has to be done by the GPU.

So, for the time being, we have a nice "HW plane enable" kernel, but there is no userland compositor in front of it! (except Android HWC...)

Can some of you review those patches and help to get it merged?
Without review from the community, shall we conclude that only us are interested in using HW planes in Weston?
