Subject: [Qemu-devel] [PATCH 05/11] s390/sclp: add reset() functions
Date: Wed, 18 Sep 2013 12:19:26 +0200 [thread overview]
Message-ID: <1379499572-49737-6-git-send-email-borntraeger@de.ibm.com> (raw)
In-Reply-To: <1379499572-49737-1-git-send-email-borntraeger@de.ibm.com>
From: Heinz Graalfs <graalfs@linux.vnet.ibm.com>
Add reset() functions for event-facility, sclpconsole, and sclpquiesce.
The reset() functions perform variable initialization
at IPL and e.g. when monitor system_reset is called.
