[PATCH 0/2] x86: notify hypervisor/VMM about guest entering s2idle

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
