Let me not hinder enthusiasm here but you need to understand your cpu well before attempting any porting efforts. I would try creating a single .S file where you can switch register context between threads in assembler. Then maybe 2 simple routines that would enable the memory management, and add virtual to physical mappings to the page tables. Once you are comfortable with the above, it may start making sense transferring your work to a system like codezero. -- Bahadir _______________________________________________ codezero-devel mailing list codezero-devel@lists.l4dev.org http://lists.l4dev.org/mailman/listinfo/codezero-devel
