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 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
