[Xen-devel] Source code of DomU/Dom0 context switch resulting from writing DomU's PTE?

[XuNanxuan <nanxuan_xu@xxxxxxx>]

Hi:
 
>From some of my test I learn that when a DomU modifies its page table entry (PTE), then a context switch should happen to sync the guest page table (GPT) and shadow page table (SPT). I want to learn this part of codes, so could any one here tell me how I can find these codes? I mean codes aiming at: Updating guest PTE --> DomU/Dom0 context switch-->sync PTs
 
Thanks!
