[Qemu-devel] [PATCHv3 7/7] spapr: Improved placement of PCI host bridges in guest memory map

2016-10-12 Thread David Gibson
Currently, the MMIO space for accessing PCI on pseries guests begins at 1 TiB in guest address space. Each PCI host bridge (PHB) has a 64 GiB chunk of address space in which it places its outbound PIO and 32-bit and 64-bit MMIO windows. This scheme as several problems: - It limits guest RAM to
