[Xen-devel] Re: Getting the page fault count for domU

[Chintamani Siddeshwar <chintamani.sid@xxxxxxxxx>]

I am thinking of doing something like

1) Add a field "unsigned long page_fault_count" to struct domain defined in
in xen/sched.h

2) Increment this counter mem_paging_domctl(...) defined in
arch/x_86/mm/mem_paging.c for 
               case XEN_DOMCTL_MEM_EVENT_OP_PAGING_EVICT     

I will then access this information is available from within struct
vcpu->domain->page_fault_count.

Please correct me if my chain of thought is wrong or if it is too
simplistic.
Looking forward to your valuable comments 

    thanks
Chintamani
