I am trying to add a hypercall to replace the iret instruction in xenolinux, so that everytime control comes to xen when guest OS executes 'iret'. I found that there already exists a hypercall HYPERVISOR_iret in xen. What is the exact functionality of HYPERVISOR_iret? In which cases is it called by the guest OS? Please help. -swapna _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
