Hi all, I traced Xen''s writable page table handler: PV guests'' write operation to a pte will trap to Xen''s page fault handler ptwr_do_page_fault() which will call x86_emulate() to emulate the write. But after I print out the pte (which maps faulting virtual address) value, I was very surprised to find that, the value does not change before/after x86_emulation(). This result confuses me: so how does Xen emulate pte write then ? Thanks a lot ! -- Xinxin _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
