Subject: [Qemu-devel] [RFC PATCH v3 18/19] Implement _PS3 for dimm
Date: Fri, 21 Sep 2012 13:17:34 +0200 [thread overview]
Message-ID: <1348226255-4226-19-git-send-email-vasilis.liaskovitis@profitbricks.com> (raw)
In-Reply-To: <1348226255-4226-1-git-send-email-vasilis.liaskovitis@profitbricks.com>
This will allow us to update dimm state on OSPM-initiated eject operations e.g.
with "echo 1 > /sys/bus/acpi/devices/PNP0C80\:00/eject"
