Abstract

The invention provides a method, system and device for time synchronization of BMC (Baseboard Management Controller) and an operating system, and the method comprises the steps: obtaining video memory data issued by an operating system, and caching the video memory data through a VGA; and acquiring a data frame through the VGA cache, analyzing time information from the data frame based on a frame protocol of the data frame, and performing time synchronization of the BMC and an operating system. The BMC analyzes the video memory data issued by the operating system OS, obtains the time information and synchronizes the time of the BMC and the OS, time synchronization can be carried out as long as the OS has video memory issuing, the purpose of real-time synchronization is achieved, the whole process can be achieved by means of an existing link, additional hardware equipment or line connection is not needed, and hardware cost is not needed. And the realization is easy.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular a method, system, and apparatus for time synchronization of BMC and operating system. Background technique [0002] The stability and security requirements of the Internet age are increasingly high, and the importance of monitoring of server machine is more prominent. This requires the platform management system of BMC (Baseboard Management Controller, Best Management Controller) to make a series of monitoring and control functions, the content of monitoring is the hardware and software of the entire server, so the importance of BMC in the server field Aim. As the time factor of the reference, accurate control is required, especially between BMCs, between the local OS (Operating System, Operating System), and time is more important. [0003] Since the ARM (AdvanceD RISC MACHINE, Advanced Difficulty Collection Machine) platform and the CPU of the X86 platform have great differen...
