I've heard mentions that etnaviv could actually work. Make sure you
have a very very fresh upstream kernel, possibly Mesa master branch,
and upstream Weston 4.0.94 at least. And no propriatery drivers
anywhere. The bits needed to support etnaviv span through the whole
graphics stack, but I believe they should be mostly in place by now.

Right. It could have been a Weston issue, and if there still is a
Weston bug, we would be happy to receive a fix. But, that means you
need to reproduce the issue with upstream Weston and without
proprietary drivers.

It would also be possible to run Weston with its software renderer
(Pixman) to avoid needing any GPU drivers, on the Weston DRM backend
with upstream display drivers. Of course, doesn't help if you need
the GPU.

All that said, I'm not sure if anyone else is seriously testing
suspend/resume with Weston.
