PCIe Configuration Space
PCIe Compatibility
PCIe is completely compatible with existing deployed PCI software. To achieve this,
PCIe hardware implementations conform to the following requirements:
PCIe devices implement all registers required by the PCI specification as well as the
power management registers and capability pointers specified by the PCI power
management specification. In addition, PCIe defines a PCIe capability pointer to
indicate support for PCIe extensions and associated capabilities.
The 82574 is a single function device - the LAN function.
The 82574 contains the following regions of the PCI configuration space:
• All devices required to be supported by the deployed PCI software must be
• Devices must not require any resources (such as address decode ranges and
• Devices in their default operating state must conform to PCI ordering and cache
• PCIe devices must conform to PCI power management specification. PCIe devices
• Mandatory PCI configuration registers
• Power management capabilities
• MSI capabilities
• MSI-X capabilities
• PCIe extended capabilities

must not require any register programming for PCI-compatible power
management, beyond those available through PCI power management capability
registers. Power management is expected to conform to standard PCI power
management using existing PCI bus drivers.
