Subject: [PATCH 0/2] x86: notify hypervisor/VMM about guest entering s2idle
Date: Thu, 9 Jun 2022 11:03:26 +0000 [thread overview]
Message-ID: <20220609110337.1238762-1-jaz@semihalf.com> (raw)
This patchset introduces support which allows to notify first the
hypervisor about guest entering the s2idle state (patch #1) and second
propagate this notification to user-space so the VMM can take advantage
of such notification (patch #2).
Please see individual patches and commit logs for more verbose description.
