This is a follow up to my previous series to get us started in the QOM
direction. A few things are different this time around. Most notably:
1) Devices no longer have names. Instead, path names are always used to
identify devices.
2) In order to support (1), dynamic properties are now supported.
3) The concept of a "root device" has been introduced. The root device is
roughly modelling the motherboard of a machine. This type is a container
type and it's best to think of it as something like a PCB board I guess.
To try it out, here's an example session:
Launch:
address@hidden:~/build/qemu$ x86_64-softmmu/qemu-system-x86_64 -hda
~/images/linux.img -snapshot -device virtio-balloon-pci,id=foo -qmp
unix:/tmp/server.sock,server,nowait
Explore the object model:
address@hidden:~/git/qemu/QMP$ ./qom-list /
peripheral/
i440fx/
address@hidden:~/git/qemu/QMP$ ./qom-list /i440fx/
piix3/
address@hidden:~/git/qemu/QMP$ ./qom-list /i440fx/piix3

address@hidden:~/git/qemu/QMP$ ./qom-list /i440fx/piix3/rtc

Anthony Liguori (18):
qom: add new dynamic property infrastructure based on Visitors
qom: register legacy properties as new style properties
qom: introduce root device
qdev: provide an interface to return canonical path from root
qdev: provide a path resolution
qom: add child properties (composition)
qom: add link properties
qapi: allow a 'gen' key to suppress code generation
qmp: add qom-list command
qom: qom_{get,set} monitor commands
qdev: add explicitly named devices to the root complex
dev: add an anonymous peripheral container
rtc: make piix3 set the rtc as a child
rtc: add a dynamic property for retrieving the date
qom: optimize qdev_get_canonical_path using a parent link
Make qmp.py easier to use
Add test tools
qdev: split out QOM functions to separate files
