Subject: driver notification when switching between battery vs AC power?
Date: Fri, 5 Mar 2021 09:07:48 +0100 [thread overview]
Message-ID: <20210305080748.GA17954@lst.de> (raw)
Hi Rafael,
do we have infrastructure that notifies the driver when a system is
switching from batter to AC power? There is a proposal to make the
Linux NVMe driver power management match the policy used by the
Windows driver more closely, which does this and we'd like to prototype
that to check what difference the policy makes.
