[Qemu-devel] [RFC PATCH v1 00/20] Refactor PC machine to take advantage of QOM

[Hu Tao <hutao@cn.fujitsu.com>]

This is a re-do of original series posted by Anthony Liguori at:
http://lists.gnu.org/archive/html/qemu-devel/2012-01/msg03501.html

I post this series because:
  1. there are no news from Anthony since the first version for more than a year
  2. Li Wanfeng di some work on the refactor last year, but no news for half a year
  3. memory hotplug requires i440fx pmc refactor if I'm getting it right
     (http://lists.gnu.org/archive/html/qemu-devel/2012-12/msg02693.html)


Problems:

  1. isapc is broken
  2. too many code duplication between piix and ich
  3. others


TODO:

  1. make a proper ISA model
  2. a base class PCSuperIO that piix and ich can inherit from. isapc may also
     be modelled with PCSuperIO. But there was argument on this.
     (http://lists.gnu.org/archive/html/qemu-devel/2012-01/msg03626.html)
  3. a base class MemoryController that i440fx-pmc and q35-mch can inherit from
  4. others



Hu Tao (20):
  i440fx: remove unused parameter i440fx_state of i440fx_init.
  i440fx: rename i440FX to i440FX-PMC
  i440fx: rename i440FX-pcihost to i440FX
  i440fx: prepare for composition
  piix3: make PIIX3-xen a subclass of PIIX3
  piix3: prepare for composition
  piix3: create piix3 through composition.
  rtc: remove rtc_set_date
  ich9: function rename
  piix3,ich9: create the HPET through composition
  add rtc_set_irq
  piix3,ich9: create the RTC through composition
  piix3,ich9: create pit through composition
  piix3,ich9: create pc speaker through composition
  i440fx pmc: create pmc through comosition
  i440fx-pmc: calculate PCI memory hole directly
  i440fx-pmc: create pci address space
  q35-mch: create pci address space
  i440fx-pmc: move ram initialization into i440fx-pmc
  q35-mch: move ram initialization into q35-mch
