[Qemu-devel] [PATCH 00/26] VMState: port several pc devices to vmstate

[Juan Quintela <quintela@redhat.com>]

This series:
- remove support for RAM v1 and v2 (I created an image with latest qemu
  before switching to RAM v3 and try to load with current qemu).
  It don't work (physical_ram_size value has changed), and it don't work
  since at least April).  I went to that commit, and after fixing RAM,
  ide didn't load, and vga screen got corrupted).
- Remove SaveVM v2 support.  This support is older than then switch to RAMv3,
  if you can't load RAM -> you can't load any image in any meaningful way.
- port several devices to vmstate.
- To port timers, I have to move ticks_per_sec in an accessor function
  patch is quite big, but it is trivial.

Devices left to have my minimal pc using only vmstate:
- cpu (dragons here, this is huge and has all special cases that you can think)
- ide: medium size, identiyfy_data that can/can't be there is the
  more complicated thing.
- virtio-net: more dragons here, we need a nice way to split virtio & virtio-pci
  just now their relation is too incestuous.
- mc146818rtc: See my other RFC mail about changing how rtc-td-hack is handled
  during save/load.

I guess that I missed some device, but this is one start.

Later, Juan.

Juan Quintela (26):
  ram: remove support for loading v1
  ram: Remove SaveVM Version 2 support
  Remove SaveVM v2 support
  timers: remove useless check
  Unexport ticks_per_sec variable.  Create get_ticks_per_sec() function
  timers: Createt TimersState and put all timers state there
  timers: move them to VMState
  vmstate: add sensible arguments to vmstate_unregister()
  vmstate: rename run_after_load() -> post_load()
  vmstate: Add pre_load() hook
  vmstate: Add pre/post_save() hooks
  vmstate: port cpu_comon
  vmstate: port fw_cfg device
  vmstate: port i8259 device
  vmstate: add support for uint8_t equal
  vmstate: port fdc device
  vmstate: add support for arrays of uint16_t
  vmstate: port dma device
  vmstate: port vmmouse device
  vmstate: port pckbd device
  vmstate: add uint64 array support
  vmstate: port ioapic device
  hpet: it is imposible that qemu_timer field is NULL at this point
  vmstate: port hpet device
  vmstate: port serial device
  vmstate: port cirrus_vga device
