Precision Time Measurement (PTM)

Hardware protocol for precise coordination of events and timing information across multiple upstream and downstream devices using Transaction Layer Protocol (TLP) Message Requests. Minimizes timing translation errors resulting in the increased coordination of events across multiple components with very fine precision.

All of the PCH PCIe* Controllers and their assigned Root Ports support PTM where each Root Port can have PTM enabled or disabled individually from one another.
