[Qemu-devel] [PATCH 0/6] pci: keep window properties up to date

[Michael S. Tsirkin]

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
