Subject: [Qemu-arm] [PATCH v1 0/5] Fix crashes with introspection
Date: Thu, 12 Jul 2018 17:30:58 +0200 [thread overview]
Message-ID: <1531409463-3843-1-git-send-email-thuth@redhat.com> (raw)
As discovered recently, you can crash QEMU with a lot of devices
that do not get the reference counting of child objects right.
You just have to run 'device-list-properties' and call 'info qtree'
afterwards.
This patch series fixes a bunch of these problems in the ARM code.
I did not fix all problems yet, since it is quite time consuming
and I first want to get some feedback whether this is the right
way to go or not.
Thomas Huth (5):
qom/object: Add a new function object_initialize_as_child()
hw/core/sysbus: Add a function for creating and attaching an object
hw/arm/bcm2836: Fix crash with device_add bcm2837 on unsupported
machines
hw/arm/armv7: Fix crash when introspecting the "iotkit" device
hw/cpu/a15mpcore: Fix introspection problem with the a15mpcore_priv
device
