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.
