Dmitry Baryshkov requested to merge lumag/drm:writeback into main Aug 30, 2023

Add writeback support to modetest with the below options:

Passing in -a -c will now also show the writeback connector
Dump the writeback output buffer to bitstream Usage: "./modetest -M msm -s <connector_id>: -a -o -P <plane_id>@<crtc_id>:+0+0@RG24"

This currently supports single writeback connector.
