Subject: [PATCH 0/3] Disable Suspend-to-Idle in Hyper-V and Fix Hibernation Interruptions
Date: Thu, 12 Sep 2024 14:27:47 -0700	[thread overview]
Message-ID: <1726176470-13133-1-git-send-email-ernis@linux.microsoft.com> (raw)

It has been reported that Hyper-V VM users can unintentionally abort
hibernation by mouse or keyboard movements. To address this issue,
we have decided to remove the wakeup events for the Hyper-V keyboard
and mouse driver. However, this change introduces another problem: 
Suspend-to-Idle brings the system down with no method to wake it back up.

Given that there are no real users of Suspend-to-Idle in Hyper-V,
we have decided to disable this feature for VMBus. This results in:

$echo freeze > /sys/power/state
> bash: echo: write error: Operation not supported

The keyboard and mouse were previously registered as wakeup sources to
interrupt the freeze operation in a VM. Since the freeze operation itself
is no longer supported, we are disabling them as wakeup events.

This patchset ensures that the system remains stable and prevents
unintended interruptions during hibernation.
