    Changing CS in Long mode

    jleehand

      Hello,

      I'm not sure if this is the right place to ask this kind of question but I couldn't find any more relevant forum on AMD's website.

      I am building interrupts into a OS project that we are working on and in order to validate the working GDT I am trying to load the CS register in 64 bit mode. I would to have liked to use long jump to do this but it appears that there is no instruction for that in AMD x86-64. I was wondering if there is a recommended way to do this?

      Thanks,

      Jeremy
