--- Quote Start --- I want to know If I can test PCIe Root Port without Connecting/attaching Endpoint with Linux Kernels. --- Quote End --- You mean you just want to see if the wires on the PCIe connector are working? If the root-complex is an FPGA, then sure, you can do whatever you like. For example, you can test a high-speed transceiver by configuring it in BIST mode and have it generate a PRBS pattern, or you can use a transceiver IP core and configure it manually and have it output a desired pattern. For example, a square wave at a low enough frequency that you can see it on a scope. You can also loop back the TX and RX differential signals using a PCIe breakout cable (Samtec sell them). http://www.samtec.com/technical-specifications/default.aspx?seriesmaster=pcrf I use this type of cable (the one with the peripheral style connector) as a way to access transceivers on kits that do not have HSMC or FMC connectors.
