Summary

L1 PM Substates with CLKREQ, Revision 1.0a, defines an optional mechanism for lower idle power consumption in PCIe Links, allowing for near complete removal of power for high-speed circuits. The new L1 PM Substates are applicable in both ASPM and PCI-PM L1 Link states, utilizing a per-Link sideband signal called CLKREQ#. This mechanism enables dramatically lower idle power, benefiting low-power and battery-based applications, and reducing power waste in high-lane-count PCIe solutions. The change impacts components that support this optional capability, requiring capability discovery and enabling, and affecting Link power control and reference clock mechanisms.
