Hi, Tried these patches today on Win2008 x64 guest with 64bit devices. I've got BSOD on boot. I guess windows don't like changes in _CRS.

Hi,
This patch series makes the PCI I/O windows runtime-configurable via qemu firmware config interface. Main advantage is that we can size and shuffle around the PCI i/O windows according to the amount of memory the virtual machine has. We don't need a hole for 64bit PCI bars, we can just map them above the main memory. The hole for 32bit PCI bars can be enlarged for guests with less than 3.5 GB of memory.
Oh, and the pci device initialization fix is there too ;)
cheers, Gerd
