The non-prefetchable MMIO aperture of a bridge can never fall outside of the 32-bit address space. Namely, the MemoryBase and MemoryLimit fields in PCI_BRIDGE_CONTROL_REGISTER have type UINT16, and based on the PCI-to-PCI Bridge Architecture Spec, Chapter 3.2, the actual MMIO aperture is determined as in: NonPrefetchMemoryBase = (((MemoryBase & 0xFFF0u) >> 4) << 20) | 0x00000 NonPrefetchMemoryLimit = (((MemoryLimit & 0xFFF0u) >> 4) << 20) | 0xFFFFF In "OvmfPkg/PciHotPlugInitDxe", the "mPadding.MmioPadding.AddrSpaceGranularity" field is currently initialized to 64. According to the above, this is useless generality: a non-prefetchable MMIO reservation may only be satisfied from 32-bit address space. Update the field to 32. In practice this change makes no difference, because PciBusDxe already enforces the 32-bit limitation when it sees "non-prefetchable" from (SpecificFlag==0). Quoting commit |
