It turns out that some 32 bit windows guests crash if 64 bit PCI hole size is >2G. Limit it to 2G for piix and q35 by default.
v1-v2: * redone using QOM properties to pass value around v2-v3: * make pci_hole[64]-(start|end) properties read-only * add pci-hole64-size property to manage hole size git-tree for testing: https://github.com/imammedo/qemu/commits/pcihole64_fix_v3 Igor Mammedov (4): pc: add I440FX QOM cast macro pc: replace i440fx_common_init() with i440fx_init() pc: add Q35 to QOM composition tree under /machine pc: limit 64 bit hole to 2G by default Michael S.
