Precision Time Measurement (PTM), a supported feature in the PCI-SIG® PCI Express 3.0 specification, defines a new protocol of timing measurement and synchronization messages for time-sensitive media and server applications. Examples include industrial automation, instrumentation, geological sciences, telecom synchronization, and synchronized audio/video systems, among others. PTM enables systems that require high precision timing the ability to monitor and track the time of transactions with sub-microsecond timing accuracy while accelerating server application performance.
ConnectX-5 and onward support PTM capability, however the software support is currently not part of our solution package.
Please contact your application engineer for assistance.
