I was not able to test it on my own, this is a call for testing for the
owners of these platforms. The git version of modetest now fully
supports writeback.

Compile libdrm/modetest from git version, run modetest -ac to determine
the writeback connector, cat /sys/kernel/debug/dri/0/state to determine
spare CRTC and plane, then run something like:

modetest -M msm -a -s 36 at 85:1024x768 -o test.d -P 79 at 85:1024x768

where 36 is the Writeback connector id, 85 is CRTC and 79 is the plane.

Then press Enter and check the test.d file for the raw image dump.
