[Qemu-devel] [PATCH v5 0/3] refactor PC machine, i440fx and piix3 to tak

Subject: [Qemu-devel] [PATCH v5 0/3] refactor PC machine, i440fx and piix3 to take advantage of QOM
Date: Mon, 23 Jul 2012 20:35:56 +0800

This series aggressively refactors the PC machine initialization to be more
modelled and less ad-hoc.  The highlights of this series are:

1) Things like -m and -bios-name are now device model properties

2) The i440fx and piix3 are now modelled in a thorough fashion

3) i440fx_init is trivialized to creating devices and setting properties

4) convert PCI host bridge to QOM

The point (3) is the most important one.  As we refactor in this fashion,
we should quickly get to the point where machine->init disappears completely in
favor of just creating a handful of devices.

The two stage initialization of QOM is important here.  instance_init() is when
composed devices are created which means that after you've created a device, all
of its children are visible in the device model.  This lets you set properties
of the parent and its children.

realize() (which is still called DeviceState::init today) will be called right
before the guest starts up for the first time.

Change in v5:
* drop patch "convert MemoryRegion to QOM" and 
"prepare to create HPET, RTC and i8254 through composition"
* add Andreas' recent attempt against pci_host

Change in v4:

*rebase patchset

Changes in v3:

* fix coding style issues
* fix rebase error
* add changes log

Changes in v2:

* Rebase patch series of i440fx in Anthony's qom-rebase.12 branch to upstream
* convert MemoryRegion to QOM
* convert pci_host to QOM

Anthony Liguori (3):
  eliminate piix_pci.c and module i440fx and piix3
  merge pc_piix.c to pc.c
  convert pci-host to QOM
