[Xen-devel] there is no sysret in X86_emulate, why?

[hanyandong <hanyandong@xxxxxxxxx>]

hi, all

(1)In x86_emulate(), there are sysenter/sysexit, syscall. But why no sysret?

(2)I want to iuntercept syscall/sysret, so I unset the EFER.SCE, so syscall/sysret will trap into Xen, then I emulate syscall/sysret.

But  I only see syscall and did not see one sysret,  the guest run as usual.  any one can give me an hint?
