Prelude:
*) Literature sates that task switching is performed by software instead of hardware in most modern OS.
In which ring level does a kext run? As far as I have researched the cpu will not allow a task switch from outside the GDT. Does GDT is memory protected? If so would a kext have access to it?
I have several avenues to take and I would like to explore all.
Thanks a lot in advance and happy holidays!
