Intel® Direct Connect Interface (DCI)
Direct Connect Interface (DCI) is a new debug transport technology to enable closed chassis debug through any of USB 3.2 ports out from Intel silicon. Some bridging logic is embedded in the silicon to “bridge” the gap between standard I/O ports and the debug interfaces including JTAG, probe mode, hooks, trace infrastructure, and etc. To control the operation of this embedded logic, a DCI packet based protocol is invented which controls and data can be sent or received. This protocol can operate over a few different physical transport paths to the target which known as “hosting interfaces”.
There are two types of DCI hosting interfaces in the platform:
Supported capabilities in DCI are:
