Hi fellow Xen developers,

   When I read the source code of Xen, I find some data structure is hard to understand, such as the linear pagetable and mfn_x.

    Let's consider the setting Xen 4.0.0 and 32bits, PAE-enable PV domain, how the linear pagetable shares the same machine address with current process's pagetable? I have read some documents about the implementation of linear pagetable, but I still do not well understand it.

    Another question is about mfn_x. I even cannot find out its definition:(.  I still want to know the structures involved in the mfn_x. Is it a table or...?

 

Cheers,

 
Yueqiang
