[Qemu-devel] [PATCH v3 09/17] hw/arm/fsl-imx7: Fix introspection problems with the "fsl, imx7" device |
Date: |
Mon, 16 Jul 2018 14:59:26 +0200 |
Running QEMU with valgrind indicates a problem here:
echo "{'execute':'qmp_capabilities'} {'execute':'device-list-properties'," \
"'arguments':{'typename':'fsl,imx7'}}" \
"{'execute': 'human-monitor-command', " \
"'arguments': {'command-line': 'info qtree'}}" | \
valgrind -q aarch64-softmmu/qemu-system-aarch64 -M none,accel=qtest -qmp stdio
[...]
==27284== Invalid read of size 8
==27284== at 0x618F7A: qdev_print (qdev-monitor.c:686)
==27284== by 0x618F7A: qbus_print (qdev-monitor.c:719)
==27284== by 0x452B38: handle_hmp_command (monitor.c:3446)
[...]
Use the new sysbus_init_child_obj() and object_initialize_child() to make
sure that the objects are removed correctly when the parent gets destroyed.
