[Qemu-devel] [PATCH for-2.10 04/10] s390x/css: introduce read-only property type for device ids |
Date: |
Thu, 6 Apr 2017 13:16:40 +0200 |
From: Dong Jia Shi <address@hidden>
Let's introduce a read-only property type that handles device ids of the
CssDevId type used for channel devices for future use. e.g. exposing the
busid of an I/O subchannel that is assigned to a ccw device.
