Hi Jano (or anybody else who knows),



the Beagle amdm37x display driver implements a 'mode change' entry point. Is
there any way to exercise it? Did you test it? I couldn't find any way to 
initiate mode change.




I was looking at the way mode change is implemented in libgraph/compositor,
but I don't quite understand it. A visualizer can report a 'mode change' 
notification which seem to direct the compositor to, in return, request that
visualizer to change mode, which, in reponse, changes the mode. Now that 
does not make any sense to me. Moreover, no visualizer seems to generate 
this notification so I don't see any way this could be executed.




I'm just trying to understand whether we support changing modes, and thus 
whether this is a feature that I need to implement before switching
compositor -> display server. (Also it would be good to know whether the 
mode change code in amdm37x is tested or not).




Thanks and best regards,

Jiri
