Hi,

I would like to know if it is possible in any of the L4* systems to have a setup like the following:

• The console (framebuffer) to be split into two frames/windows, say

top and bottom halves, but, each one should be used/accessed independently of each other.

• With two keyboards connected to this single system, one should be

able to use (shell) one of the keyboards with the top window, while the other should use the bottom one.

Appreciate any thoughts/inputs in this regard. Thanks!

I don't know of any L4-based system, which supports this setup out-of-the-box. IMO Genode [1] and L4Env [2] have all you need to build such a system on your own: PS/2 drivers, USB HID drivers, and frame buffer console/GUI.

Both options implicate some hacking on your part as multi-head scenarios were not addressed so far.

BTW, Genode seemlessly supports several L4 kernels, namely OKL4, Fiasco, and Pistachio. That's a nice feature if you're not certain which kernel fits your needs best and want to postpone the final decision :-)
