Problems solved by technology

[0004] In the prior art, the PCH ME debugging method is to add 3pin headers inside the board. This design lacks flexibility. If you want to realize this function after the machine is assembled, you need to disassemble the board, resulting in a waste of manpower and material resources. has certain limitations

Embodiment Construction

[0020] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] This article uses the latest Intel PCH for the LBG (Lewiburg) series of the Purley platform. Compared with the traditional PCH, this series of PCH has added many features:

[0022] 1. There are 16 sets of PCIE and 8 sets of optional PCIE connected to the CPU to realize its own 10G network function and QAT (Quick Assist Technology);

[0023] 2. Its own high-speed IO can be flexibly configured, and the control right of GPIO can also be allocated through ME;

[0024] 3. It can be used as CLK GEN, etc.

[0025] Intel's LBG PCH has a set of HOST I2C, and the PCH can be configured as a MASTER or SLAVE mode through this set of I2C. When the PCH is used as a SLAVE ...

Abstract

The invention provides a device and a method for reuse of a PCH MEdebug and a USB port in a Purley platform server system. Through an alternative selector, an I2C signal of an MEdebug and a 2.0 signal of a USB are connected to an external USB port. A function selection signal of a selector is connected with a BMC; a default function is set to be USB2.0; and the state of a function selection pin is changed through a BMC to achieve signal switching when debug ME is needed. The external USB port function is fully utilized, and meanwhile, the function of the ME debug can be quickly and simply achieved after later machine assembly is completed.

Description

technical field [0001] The invention relates to the technical field of management engines, in particular to a device and method for PCHME debugging and USB port multiplexing in a Purley platform server system. Background technique [0002] In recent years, server systems have played an important role in all aspects of society, and servers exist in almost all aspects that are closely related to our lives. With the rapid increase in the number of server system deployments, the problem of energy consumption is particularly prominent. The increase in server energy consumption is mainly reflected in the following aspects: First, the CPU. With the continuous improvement of the manufacturing process of the CPU, the frequency is getting higher and higher. While its computing power is rapidly improving, its power consumption is also increasing astonishingly; the second is Memory, with the improvement of the manufacturing process, the memory capacity is getting bigger and bigger, and...
