[Interest] QtWayland: i915 and linux-dmabuf-unstable-v1

[Johannes Pointner]

Hello,

I tried to enable the linux-dmabuf-unstable-v1 integration for
QtWayland server on a Intel Apollo Lake system(i915) but it failed
with:
qt.waylandcompositor.hardwareintegration: failed to create EGL image for plane 0
qt.waylandcompositor.hardwareintegration: failed to create EGL image for plane 1
error in client communication (pid 499)
and then the wayland client crashes(also a Qt application) with:
[destroyed object]: error 7: Import of the provided DMA buffer failed
The Wayland connection experienced a fatal error: Protocol error

I have used the linux-dmabuf-unstable-v1 integration successfully on a
i.MX6 with etnaviv.
Should this work on an Intel target too?
Versions used: Qt 5.13.2, Mesa 19.1.6, Kernel 5.5.11

Any hint would be highly appreciated.

Thx,
Hannes
