[Qemu-devel] [PATCH V4] hw/pci-host: Fix x86 Host Bridges 64bit PCI hole

2017-11-09 Thread Marcel Apfelbaum
Currently there is no MMIO range over 4G reserved for PCI hotplug. Since the 32bit PCI hole depends on the number of cold-plugged PCI devices and other factors, it is very possible is too small to hotplug PCI devices with large BARs. Fix it by reserving 2G for I4400FX chipset in order to comply
