[Qemu-devel] [PULL 44/50] spapr: enable PHB hotplug for default pseries

Subject: [Qemu-devel] [PULL 44/50] spapr: enable PHB hotplug for default pseries machine type
Date: Tue, 26 Feb 2019 15:52:58 +1100

From: Michael Roth <address@hidden>

The 'dr_phb_enabled' field of that class can be set as part of
machine-specific init code. It will be used to conditionally
enable creation of DRC objects and device-tree description to
facilitate hotplug of PHBs.

Since we can't migrate this state to older machine types,
default the option to true and disable it for older machine
