[Qemu-devel] [PATCH 10/19] boards.h: Ignore migration for SMBus devices on older machines |
Date: |
Wed, 20 Feb 2019 07:59:47 -0600 |
From: Corey Minyard <address@hidden>
Migration capability is being added for pm_smbus and SMBus devices.
This change will allow backwards compatibility to be kept when
migrating back to an old qemu version. Add a bool to the machine
class tho keep smbus migration from happening. Future changes
will use this.
