Processor—Interfaces

•PCI Express* extended configuration space. The first 256 bytes of configuration space aliases directly to the PCI Compatibility configuration space. The remaining portion of the fixed 4-KB block of memory-mapped space above that (starting at 100h) is known as extended configuration space.

•PCI Express* Enhanced Access Mechanism. Accessing the device configuration space in a flat memory mapped fashion.

•Automatic discovery, negotiation, and training of link out of reset.

•Traditional AGP style traffic (asynchronous non-snooped, PCI-X Relaxed ordering).

•Peer segment destination posted write traffic (no peer-to-peer read traffic) in Virtual Channel 0: DMI -> PCI Express* Port 0

•64-bit downstream address format, but the processor never generates an address above 64 GB (Bits 63:36 will always be zeros).

•64-bit upstream address format, but the processor responds to upstream read transactions to addresses above 64 GB (addresses where any of Bits 63:36 are nonzero) with an Unsupported Request response. Upstream write transactions to addresses above 64 GB will be dropped.

•Re-issues Configuration cycles that have been previously completed with the Configuration Retry status.

•PCI Express* reference clock is 100-MHz differential clock.

•Power Management Event (PME) functions.

•Dynamic width capability.

•Message Signaled Interrupt (MSI and MSI-X) messages.

•Polarity inversion

Note: The processor does not support PCI Express* Hot-Plug.

2.2.2PCI Express* Architecture

Compatibility with the PCI addressing model is maintained to ensure that all existing applications and drivers operate unchanged.

The PCI Express* configuration uses standard mechanisms as defined in the PCI Plug- and-Play specification. The processor PCI Express* ports support Gen 3. At 8 GT/s, Gen 3 operation results in twice as much bandwidth per lane as compared to Gen 2 operation. The 16 lanes PEG can operate at 2.5 GT/s, 5 GT/s, or 8 GT/s.

Gen 3 PCI Express* uses a 128b/130b encoding that is about 23% more efficient than the 8b/10b encoding used in Gen 1 and Gen 2.

The PCI Express* architecture is specified in three layers – Transaction Layer, Data Link Layer, and Physical Layer. See the PCI Express Base Specification 3.0 for details of PCI Express* architecture.

2.2.3PCI Express* Configuration Mechanism

The PCI Express* (external graphics) link is mapped through a PCI-to-PCI bridge structure.
