Thanks for your feedback!

I saw that there are two patch series connected to Suspend-to-RAM topic:
-https://lore.kernel.org/xen-devel/cover.1748337249.git.mykola_kvach@epam.com/
-https://lore.kernel.org/xen-devel/cover.1748848482.git.mykola_kvach@epam.com/

So it seems like we should follow a progress for these two patch series in parallel.
Or the difference is that one of patch series is for connect to guest and another
to hardware domains.

Am I missing something?
