[Xen-devel] What's the advantage of Writable pagetable?

[Chengyuan Li <chengyuanli@xxxxxxxxx>]

Hi,

Before writable pagetable is enabled, XenLinux use Hypercall to update
PTE. After the writable pagetable is enabled, it depends on page fault
to update PTE. What's the advantage then?


Thanks,
Chengyuan
