[Xen-devel] Monitoring page table entry update

[Hwandori <hwandori@xxxxxxxxx>]

Hello,

I want to monitor page table entry updates.
What functions should I monitor to do this? 
From analysis, I know that 'update_l1e' and 'update_l2e' are the lowest level functions called by 'do_mmu_update' and 'do_update_va_mapping'.
However, all page table updates are carried out in these functions?
I have Xen-3.0.4_1 and think I should monitor validation parts if  this Xen version uses writable page table.
Is this Xen version  using  wriable page table?? If so, where is the validation of written page table?

Thanks
