Hi, Norman, thanks for your thorough answer. I expected that there is some API's or variables,
like those in the Kernel Interface Page, and to check them at the runtime. But doing that at compile
time is even better. Also, the build system feature with customising through SPECS is cool, it's like
doing OOP with make :) An approach with REPOSITORIES is also nice, but several trees for one
program maybe so much.
PS: maybe, offtopic, but I'm in trouble a bit.
-- I compiled Genode for Linux, but when starting Core, it cannot initialize a framebuffer device, writes
that /dev/fb0 file doesn't exist and that I need to specify the FRAMEBUFFER variable or enable fbdev.
I tried to load 'fbdev' module with modprobe, but such a module doesn't exist.
Sorry if it's a common FAQ, but I didn't worked with framebuffer device on Linux before that. What I must do
to enable framebuffer? Need I load some driver?
