Multitasking
Posted: Mon Sep 01, 2003 3:17 pm
Hi guys. What kind of task switching method do you recommend? TSS-based or stack-based? What are the pros and cons of either? I haven't quite yet figured out how it all works. How does ring transitions work? What happends when a ring 3 app issues an interrupt (for some os service), does the CPU switch to ring 0 automatically or what does it do? Should the kernel code be interupptable? Some explanations on this stuff would be great.
Sorry for having all the questions in a big mess...
