What I'm most interested in is x86 and VESA. That's my configuration for everything beside the Raspberry Pi, which already works. It's also the most common desktop configuration, which should probably make it the highest priority of the supported platforms.

That means you have DDC working on the Raspi? For VESA you just have to make the right calls (do not remember them from the top of my head, but they are in the spec) into the VESA Bios to read the EDID. Then you are good to go.

Best, Matthias.

Without knowing all the details about Genode's framework this is
definitely possible. It basically comes down to

1. Which platform you want to target and
2. how much engineering effort you are willing to spend.

If it is x86 and the video connector is handled by VESA it is easy. It
gets more complicated for displays connected via LVDS (usually all
laptop screens) as you will need drivers for the southbridge and I2C. On
ARM platforms you will most likely need GPIO and I2C drivers.

Best,
Matthias.
