• 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
• Support for PCIe* 3.0 atomic operation, PCIe 3.0 optional extension on atomic
• Message Signaled Interrupt (MSI and MSI-X) messages
• Degraded Mode support and Lane Reversal support
• Static lane numbering reversal and polarity inversion support
• Support for PCIe* 3.0 atomic operation, PCIe 3.0 optional extension on atomic
read-modify-write mechanism
• Additional read buffers for point-point transfers. This increases the number of
outstanding transactions in point-point transfers across same processor sockets,
from previous generation of 16 to 64 in this generation.

Direct Media Interface Gen 2 (DMI2)
• Serves as the chip-to-chip interface to the Intel® C600 Chipset
• The DMI2 port supports x4 link width and only operates in a x4 mode when in DMI2
• Operates at PCI Express* 1.0 or 2.0 speeds
• Transparent to software
• Processor and peer-to-peer writes and reads with 64-bit address support
• APIC and Message Signaled Interrupt (MSI) support. Will send Intel-defined “End of
• The DMI2 port supports x4 link width and only operates in a x4 mode when in DMI2
• Operates at PCI Express* 1.0 or 2.0 speeds
• Transparent to software
• Processor and peer-to-peer writes and reads with 64-bit address support
• APIC and Message Signaled Interrupt (MSI) support. Will send Intel-defined “End of
Interrupt” broadcast message when initiated by the processor.
• Downstream System Management Interrupt (SMI), SCI, and SERR error indication
