I'd like to propose including initial support for Suspend-to-RAM in Xen 4.21.

This feature enables Xen and its guests to enter suspend state via
PSCI SYSTEM_SUSPEND. Xen suspend is triggered from the hardware domain.

Support is currently Experimental.
Thanks for your feedback!

Or the difference is that one of patch series is for connect to guest and another
to hardware domains.
