w32/w64 properties that we report in QOM are currently static, but this is wrong: guest firmware can select its own windows: optimal placement for w64 is guest-dependent, further, for Q35, w32 is affected by the MCFG base and size.
This detects the actual window configuration used by guest and reports it in QOM. Michael S. Tsirkin (6): q35: make pci window address/size match guest cfg range: add min/max operations on ranges pci: add helper to retrieve the 64-bit range range: add Range to typedefs q35: use 64 bit window programmed by guest piix: use 64 bit window programmed by guest include/hw/pci/pci.h | 1 + include/qemu/range.h | 19 ++++++++++++++++++- include/qemu/typedefs.h | 1 + hw/pci-host/piix.c | 6 ++++++ hw/pci-host/q35.c | 16 ++++++++++++++++ hw/pci/pci.c | 43 +++++++++++++++++++++++++++++++++++++++++++ 6 files changed, 85 insertions(+), 1 deletion(-) -- MST
