OK. I will add the dependency statement in next version.
We tested the basic function of LASS virtualization including LASS
enumeration and enabling in non-root and nested environment. As KVM
unittest framework is not compatible to LASS rule, we use kernel module
and application test to emulate LASS violation instead. With KVM forced
emulation mechanism, we also verified the LASS functionality on some
emulation path with instruction fetch and data access to have same
behavior as hardware.
