Now, we have assumption that SOS control whether the platform
should enter S5 or not. So when SOS tries enter S5, we just
forward the S5 request to native port which make sure platform
S5 is totally aligned with SOS S5.
With higher serverity guest introduced,this assumption is not
true any more. We need to extend the platform S5 process to
handle higher severity guest:
- For DM launched RTVM, we need to make sure these guests
is off before put the whole platfrom to S5.
- For pre-launched VM, there are two cases:
* if os running in it support S5, we wait for guests off.
* if os running in it doesn't support S5, we expect it
will invoke one hypercall to notify HV to shutdown it.
NOTE: this case is not supported yet. Will add it in the
future.
