[Xen-devel] NPT and EPT question

["bo ma" <kyle.ma83@xxxxxxxxx>]

hi,everyone

 

Recent I read AMD specification about NPT,and met with a question about a sentence.

 

The sentence is : Note that host table walks for guest page tables are always treated as data writes.I don't know why treated as data writes?

 

In intel EPT ,is it the same? or treated as data reads?

 

Thanks a lot for any help or resource for the aquestion.
