I have similar problem. Currently applications on linux can't use mmap of framebuffer(/dev/fb0). When apps access memory to get through mmap, it occurs page fault.
Without goos, fbdrv of L4 cell, mag, l4fb drv in linux, etc on, Is there ways that it modify <linux lcd device driver> little bit as other linux device drivers
In other words, could Apps use allocated memory in linux kernel?
As a guide, Because of using dedicated frame buffer only in one cell(linux), it mustn't use things like goos, mag.
I'm not sure I'm getting your question right but you want to have an L4Linux with direct fb access? This is a rather unusual setup but nevertheless possible. In any case you need fbdrv because it's setting up the fb. One common exception is on x86 where the bootloader can also set it up. Regarding input handling L4Linux would probably do it with its own drivers.
