'How to implement software task switching?

I have read in intel manuals, AMD manuals and in other OS development forums how to implement task switching, but i still have some doubts on the use of TSS (Task State Segment).

I have read that TSS are used in hardware task switching, but (if I'm not wrong) are also used in the implementation of user space.

So, there are the questions that i have:

  • The TSS are implemented and used in hardware task switching? Or also in software task switching?
  • If TSS are not used in software task switching, can I program my own struct that stores all the useful data ?

I want to know the best strategies and the best practises about task switching. Thank you.
