From 3d0db3e74d818ba43c62cdfb3220e551f4f5ae37 Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Thu, 25 Feb 2016 12:08:00 +0100 Subject: [PATCH] spapr_rng: disable hotpluggability It is currently possible to hotplug a spapr_rng device but QEMU crashes when we try to hot unplug: ERROR:hw/core/qdev.c:295:qdev_unplug: assertion failed: (hotplug_ctrl) Aborted This happens because spapr_rng isn't plugged to any bus and sPAPR does not provide hotplug support for it: qdev_get_hotplug_handler() hence return NULL and we hit the assertion. And anyway, it doesn't make much sense to unplug this device since hcalls cannot be unregistered. Even the idea of hotplugging a RNG device instead of declaring it on the QEMU command line looks weird. This patch simply disables hotpluggability for the spapr-rng class.
