Hello, I am studing Xen hypercall now. I found that hypercall is invoked via hypercall_page, which is only filled with (in no-hypervisor-kernel-mode ): mov $i, %eax int $0x82 ret Why not invoked the hypercall directly by "int $0x82" ? What's the advantage of using hypercall_page? Thanks, Wu _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
