Hi Andreas, Don't worry about "misunderstanding" on my part, I actually value other people's input. I started this for some needs I had, I'm happy to share it, but I'm also not able to test it in all configurations, and I might overlook some other people's needs, so I'm fine with suggestions. There have been changes recently regarding HDMI handling by the vc4 driver, but I'm not sure if changing the screen resolution is supported/working. I may try to test it, do you have some settings in mind that I should test?

One question: are you able to change screen resolution for HDMI monitor (elder sdl fullscreen games need that)? This was not possible for kernel 4.1. Just to avoid misunderstandings: I like this patch series very much and would be happy to see it applied.
