Does this kernel patch help?
agd5f drm-next-3.18-wip + patch is still bad.
Bad can be a bit variable, but I would call it as one of the better bads and the vram usage is closer to a good - pic to follow.
Another observation - On good or bad the demo takes a while to get going.
Time to start of normal rendering on this patched kernel is around 2m5s
If I wiggle the window around while it's loading/stuck = 1m23s
