Abstract

The invention provides a system state display method and device based on a CPLD (Complex Programmable Logic Device). The method comprises the following steps that: through the CPLD, monitoring the activation state of a BMC (Baseboard Management Controller); when the BMC is not activated, sending system state information obtained by a PCH (Platform Controller Hub) to the CPLD, carrying out LPC (Linear Predictive Coding) decoding on the system state information by the CPLD, outputting the decoded system state information through a simulation UART (Universal Asynchronous Receiver/Transmitter) interface, and displaying the decoded system state information; when the BMC is activated, sending the system state information obtained by the PCH to the BMC, carrying out LPC decoding on the system state information, and outputting and displaying the decoded system state information through an SYS UART interface. By use of the method, a CPLD chip is selected to assist the BMC in outputting the system UART interface, a GPIO (General Purpose Input/Output), the LPC and the UART is analyzed, the relevant signal of a peripheral chip is detected, the UART interface output is simulated, and therefore,state information can be more comprehensively collected.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to a CPLD-based system status display method and device. Background technique [0002] With the development of information technology, servers are used more and more widely, and the performance of servers is also continuously upgraded. BMC (Baseboard Management Controller, Baseboard Management Controller) is the main control chip and monitoring chip in the server system. There are more and more jobs, and more and more information needs to be collected and monitored. [0003] Due to the limited number of logic units and pins of the BMC, it is impossible to capture fast-changing system signals, and because the BMC itself needs a certain startup time and restart operation restrictions, the entire system cannot be monitored in real time at a certain point in time and control; and BMC has many monitoring and management functions for the system, and the load is relatively large,...
