Abstract

The invention discloses an XDP and DCI hybrid debugging interface hardware topology structure in an 8 way server. The structure comprises two calculating boards Node0 and Node1, a backplane, an XDP connector interface for SDP debugging, PCH which is arranged on the calculating boards and used for DCI debugging, channel switch modules arranged on the calculating boards respectively and a CPLD module performing logic control on the channel switch modules; the calculating boards Node0 and Node1 perform signal interconnection through the backplane, four processors CPU0, CPU1, CPU2 and CPU3 are configured respectively, the XDP connector interface and the PCH are connected with output ends of the channel switch modules respectively, and input ends of the channel switch module are connected withthe CPLD module. By means of bottom layer hardware logic control, mixed use of the two debugging interfaces XDP and DCI is achieved, multiple application requirements are met, and the structure has the advantages of being simple and reliable.

Description

technical field [0001] The invention relates to the technical field of server debugging, in particular to a hardware topology structure of an XDP and DCI hybrid debugging interface in an 8-way server. Background technique [0002] The XDP (eXtended Debug Port) interface is a unique debugging interface of Intel Corporation. The XDP interface is deployed on a PCB board equipped with an intel chip. Cooperate with XDP equipment and related software to perform silicon-level and system-level debugging, testing, and troubleshooting. The XDP debug interface includes JTAG (Joint Test Action Group) bus, operation control, I2C, and debug bus. Among them, the JTAG bus is the most important component, and most of the debugging work can be completed through JTAG. The JTAG bus consists of TDI, TDO, TCK, TRST, and TMS signals. XDP extends JTAG by allowing the execution of two independent clock domain scan chains. The advantage of separating the scan chain into two clock domains is that...
