I was thinking of prototyping a Raspberry pi device driver in user space. As I boot it as a terminal I am hostowner so I should have access to /dev/mem, alternatively I could write a little toy device driver to create a named segement that I could segattach() to - this has the advantage that the code I write will be more directly transferable to a real kernel driver.
anyone tried this? is it just silly, the kernel boot time being so low that its not worth it? what do you think? -Steve
