Datasheet, Volume 1
• Supports receiving and decoding 64 bits of address from PCI Express*
— Memory transactions received from PCI Express* that go above the top of
physical address space (when Intel VT-d is enabled, the check would be against
the translated HPA (Host Physical Address) address) are reported as errors by
the processor.
— Outbound access to PCI Express* will always have address bits 63 to 46 cleared
• Re-issues Configuration cycles that have been previously completed with the
Configuration Retry status
• Power Management Event (PME) functions
• Message Signaled Interrupt (MSI and MSI-X) messages
• Degraded Mode support and Lane Reversal support
• Static lane numbering reversal and polarity inversion support
