[Qemu-devel] [PATCH 14/23] s390/sclp: introduce a root sclp device |
Date: |
Mon, 31 Aug 2015 13:13:54 +0200 |
From: David Hildenbrand <address@hidden>
Let's create a root sclp device, which has other sclp devices as
children (e.g. the event facility for now) and can later be used
for migration of sclp specific attributes and setup of memory.
