DSDT-based debugging method and debugging system

Abstract

The invention discloses a DSDT (Differentiated System Description Table)-based debugging method and debugging system. The system comprises a debugging terminal and a debugging information analysis terminal connected with the debugging terminal through a serial port line. The debugging terminal is used for reading BIOS (Basic Input Output System) data pre-stored in a mainboard ROM (Read Only Memory) during system startup, calling out a DSDT added with debugging information in the BIOS data, debugging all hardware described in the DSDT one by one according to the debugging information added in the DSDT, and generating hardware debugging information. The debugging information analysis terminal is used for receiving the hardware debugging information from the debugging terminal through the serial port line, analyzing the hardware debugging information, and displaying a hardware debugging information analysis result. The DSDT-based debugging method and debugging system can be suitable for different operation system environments, and can realize integrity detection of the hardware in the debugging terminal and obtain the quick, comprehensive, accurate and reliable debugging information analysis result.

Description

technical field [0001] The present invention relates to the technical field of debugging, and more specifically, relates to a debugging method and a debugging system based on a DSDT table. Background technique [0002] DSDT is an important interface for interaction between BIOS and operating system, and also an important interface for operating system to access hardware. In the process of BIOS development, problems related to the operating system are often encountered, and these problems often involve the tracking and debugging of DSDT. Currently, the ACPI-based debugging method is widely used, but there are also many defects in the ACPI-based debugging method, which are specifically manifested in: [0003] 1. For the Windows operating system, a series of symbol files, drivers, and applications need to be installed, and there are many versions of symbol files; [0004] 2. For Linux, because there are too many versions of Linux, the debugging method based on ACPI is not fea...
