is there any tutorial/documentation for writing relocatable modules for
the kernel or just stuff on the structure of it.
I have been able to get a sort of bare bones module that does
nothing loaded and unloaded (the code was just stripped down
from some other device driver module) but I cant get new
functions, I supose they would be syscalls to work. If I just
want to add a few syscalls and not deal with any hardware, how
do I "register" them so the kernel knows to use them.
When I wrote one such function just to try and return one char,
I wrote program to test it but could not get it linked
any hep much apprieciated.
