[Xen-devel] Page fault for paravirtualization?

[Jun Koi <junkoi2004@xxxxxxxxx>]

Hi,

I am trying to understand how Xen handle pagefault for
paravirtialization VM on x86.

In xen/arch/x86/traps.c, do_page_fault() calls fixup_page_fault(),
which calls paging_fault(). Then paging_fault() calls
v->arch.paging.mode->page_fault() in include/asm-x86/paging.h

However, I dont see where in the code we assign v->arch.paging.mode
for PV domain. I grep around for many possible words, but didnt see
anything interesting.

Anybody please help?

Thanks a lot,
Jun
