WebWhen an SKP Ordered Set is transmitted by a PCIe Root Complex or Endpoint, it is transmitted with three SKP symbols. If two Retimers are present in the Link, each may remove one SKP symbol, leaving just one SKP symbol in the SKP OS received by the downstream device. http://xillybus.com/tutorials/pci-express-tlp-pcie-primer-tutorial-guide-1/

WebApr 10, 2012 · SKP Ordered Sets must be scheduled and transmitted between FTSs as necessary to meet the definitions in Section 4.2.7 with the exception that no SKP Ordered Sets can be transmitted during the first N_FTS FTSs. A single SKP Ordered Set is always sent after the last FTS is transmitted. WebLink training involves the exchange of ordered sets of data, including training sequence 1 (TS1) and training sequence 2 (TS2), between the downstream port and upstream port. How PCIe Link Training Is Implemented. For example, PCIe 4.0 link training begins with a speed-change negotiation and extends from phase 0 through phase 3.
