title: Does AMD support x2APIC?
body: <p>I'm a learner of OS, and trying to write a kernel.</p>
  
  <p>I googled for "AMD x2APIC" and found out some of the information about EPYC 7002 series seems like to support it.</p>
  
  <p>But I cannot find the relative documentation.</p>
  
  <p>So I would like to ask if the recent AMD processors support it, and if yes, where I can find documentation.</p>
