hey everyone,
I have a project OS going on and I think that it's progressing nicely.
It is written in as much C++ as possible with a little bit of assembly to glue things together.
I have kernel space threading (longjmp technique), a basic heap (chunks taken from a constant size byte array), lots of syncronization logic primitives such as semaphores and monitors, keyboard input, and loaded through grub.
Firstly, I have no code in my OS yet to setup a GDT, to be honest I am a little unclear of how this functions (i suppose it is similar in setup ti IDT entries). What I really want is to not use segments at all and simply use paging.
Is there any solid examples/explainations of how these things work. I have not toys much with the DS, CS registers, I've just been preserving how they are set in the grub multiboot example.
any advice would be much appreciated.
Also, I am planning on purchases Tanenbaums Implementation of Minux book for a good reference of things, any others recomended?
