    Intel VT-d2 VS Intel VT-d

    JoyZheng

      I hope someone can help to explain the difference Intel VT-d2 and Intel VT-d.

      it confuse me.

      As I know :

      Intel®VT-d2 Features

      — Original Intel VT-d features

      — Improved invalidation architecture

      — End point caching support (ATS)

      — Interrupt remapping

      — 4K/2M/1G super page support

      (From Grantley Haswell V3 EDS1)

       

      Could I talk it, Intel VT-d2 is the improved Intel VT-d technology for Grantley platform, just like (Intel® I/OAT)4 for Grantley, is it right?
