Hello Genodians,

I have been playing around with Genode on seL4 for the last few days and have a 
couple of questions.

[1] Did any modifications need to be made to the seL4 source code for Genode to 
work properly? 

[2] I encountered a couple of strange warnings when running the "Hello world" 
scenario from the Genode foundations book. Below is the clipped console log 
showing the exact messages.

. . .
Booting all finished, dropped to user space
Warning: device memory in range [0000000400000000,0000000800000000) is 
unavailable (due to limited untyped cnode range) // To which device is this 
referring?

Warning: void Core::Rpc_cap_factory::free(Genode::Native_capability) not

[init -> hello] Hello world

I am not yet familiar (still learning) the internals of seL4 and core, so 
apologies if these questions have obvious answers.

Thanks in advance,
Zachary Zollers
