[Qemu-devel] [PATCH v19 0/9] Virtual Machine Generation ID

[Igor Mammedov]

Changes since v18:
  - drop MachineClass->default_props approach and make
    setting compat_props to work incrementaly which
    allows to use it for default properties as well and
    reduces data duplication as result of removing
    nesting in [PC|SPAPR]_COMPAT_* macroses.
Changes since v17:
  - make BAR prefetchable to meet cached req of MS spec
  - rename UUID/uuid to GUID/guid across series to match spec
  - qmp: add new GuidInfo type and use it instead of UuidInfo
  - tests: fail if test is timed out when waitng for address
Changes since v14:
  - statically reserve used BAR resources in SSDT, so
    that Windows won't claim them during PCI rebalancing
  - support VGID page in high mem in addition to low mem
  - add QMP/HMP interfaces to get/set VM Generation ID
  - do not consume a PCI slot by default and attach
    vmgenid device as a function of multifuction
    ISA bridge.
  - allow only one vmgenid device instance

It's respin of v14* series which uses a PCI BAR to map
VGID page in guest AS.

Tested with WS2012R2x64, older Windows versions which don't
support vmgenid boot fine but show unknown device
which is expected.

    SCI irq
  pc: add a Virtual Machine Generation ID device
  tests: add a unit test for the vmgenid device.
  qmp/hmp: add query-vm-generation-id and 'info vm-generation-id'
    commands
  qmp/hmp: add set-vm-generation-id commands
  machine: add properties to compat_props incrementaly
  pc: put PIIX3 in slot 1 explicitly and cleanup functions assignment
  pc/q53: by default put vmgenid device as an function of ISA bridge
