[Qemu-devel] [PATCH v2 00/18] Xen PV backend 'qdevification' |
Date: |
Thu, 6 Dec 2018 15:08:26 +0000 |
This series introduces a new QOM compliant framework for Xen PV backends.
This is achieved by first moving the current non-compliant framework aside,
before building up a new framework incrementally.
This series was prompted by a thread [1] started by Kevin Wolf in response
to patches against xen_disk.c posted by Tim Smith. Therefore, alongside
the patches introducing the new framework, other patches build up a QOM
compliant replacement for 'xen_disk', called 'xen-qdisk'. Patch #16 swaps
this new device into place (having establisheda mechanism to auto-
instantiate devices that is compliant with existing Xen toolstacks in
patch #15) and patch #18 then removes the old xen_disk code.
Subsequent series will port other Xen PV backends across to the new
framework.
The series is also available as a repository branch [2] on xenbits.xen.org.
