Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a BIOS dynamic debugging method, system, storage medium and device. Background Art

[0002] BIOS (Basic Input / Output System) is a basic input / output system. Its main function is to initialize computer hardware and boot the operating system. It plays a very important role in the computer system. However, with the rapid development of the computer industry, the CPU (central processing unit) and other hardware devices are constantly updated, and BIOS has gradually become a bottleneck in system development. It is mainly manifested in low development efficiency, poor performance, poor functional scalability and slow upgrades, security issues, and does not support booting from addresses above 2TB on the hard disk.

[0003] Based on the above limitations, UEFI (Unified Extensible Firmware Interface) was born. It is a new standard that defines the interface between the operating system and platform firmware. The birth of UEFI has greatly promoted the application and development of BIOS. The BIOS currently used is based on the UEFI standard. If there is no special explanation, BIOS will refer to UEFI BIOS.

[0004] During the POST (power-on self-test) phase, the BIOS will print a large number of startup logs through the serial port to display the current startup phase and the initialization status of each stage of the platform. The BIOS code can control whether these logs are compiled into the Image (image file). If the BIOS turns on the Debug function, the Debug Log will be compiled and printed through the serial port during POST; if the BIOS turns off the Debug function, the Debug Log will not be compiled and no Log will be printed during POST.

[0005] In the prior art, if different debugging levels of logs are needed, the debug mode needs to be frequently turned on or off, and the BIOS image needs to be recompiled and the BIOS needs to be burned and updated each time, which is cumbersome and time-consuming. Summary of the invention

[0006] In view of this, the purpose of the present invention is to propose a BIOS dynamic debugging method, system, storage medium and device to solve the problem in the prior art that when logs of different debugging levels are required, the debugging mode needs to be frequently switched and the BIOS image file needs to be recompiled each time, resulting in cumbersome operation and low efficiency.

[0015] In some embodiments, the method further comprises:

[0016] Add a debug mode control option in the BIOS setup interface to control whether the debug mode is turned on or off.

[0017] In some embodiments, the on state of the debug mode corresponds to a first preset debug level, and the off state of the debug mode corresponds to a second preset debug level.

[0018] Another aspect of the present invention further provides a BIOS dynamic debugging system, comprising:

[0023] In some embodiments, the log printing module is further configured to print a log of a first preset debugging level in response to the control data being a first value; or to print a log of a second preset debugging level in response to the control data being a second value.

[0024] In some embodiments, a debugging mode control module is also included, which is configured to add a debugging mode control option in the BIOS setting interface to control the opening or closing of the debugging mode.

[0025] In some embodiments, the on state of the debug mode corresponds to a first preset debug level, and the off state of the debug mode corresponds to a second preset debug level.

[0040] Step S30, obtaining the control data in CMOS through the log printing function, and confirming the value of the control data;

[0041] Step S40: Print a log corresponding to a preset debugging level based on the value of the control data.

[0042] BIOS (Basic Input Output System) stands for Basic Input Output System. It is an industry-standard firmware interface on IBM PC (personal computer) compatible systems. BIOS is the first software loaded when a personal computer starts up. In fact, it is a set of programs fixed to a ROM chip on the motherboard of the computer. It stores the most important basic input and output programs of the computer, the self-test program after power-on, and the system self-starting program. It can read and write specific information of system settings from CMOS. Its main function is to provide the lowest-level and most direct hardware settings and control for the computer.

[0043] CMOS, also known as complementary metal oxide semiconductor, is a voltage-controlled amplifier device and the basic unit of CMOS digital integrated circuits. In the computer field, CMOS often refers to a chip that stores basic computer startup information (such as date, time, startup settings, etc.). Sometimes people confuse CMOS with BIOS. In fact, CMOS is a readable and writable parallel or serial FLASH (flash memory) chip on the motherboard, which is used to store the hardware configuration of BIOS and the user's settings for certain parameters. Today, CMOS manufacturing technology is also used to make photosensitive elements for digital imaging equipment, especially SLR digital cameras with larger film specifications.

[0044] BIOS is software and program; CMOS is chip and hardware; CMOS parameters can be set through BIOS program; CMOS is a chip on the motherboard that stores important startup parameters and uses CMOS button battery to maintain power; CMOS stores parameters and the set parameters are written into CMOS through program to set it. The system setup program in BIOS is the means to complete CMOS parameter setting; CMOS RAM is both the storage place for BIOS to set system parameters and the result of BIOS setting system parameters.

[0045] The embodiment of the present invention sets the default debugging level as the first preset debugging level in the image file when compiling the BIOS image file, adds the second preset debugging level in the image file, sets the default debugging mode to be turned on, stores control data corresponding to the first preset debugging level and the second preset debugging level in the CMOS, obtains the control data in the CMOS through a log printing function, confirms the specific value of the control data, and prints the log corresponding to the preset debugging level based on the value of the control data, so that the debugging mode can be turned on or off without recompiling and burning the BIOS image file each time, thereby improving the convenience of the BIOS debugging process and the debugging work efficiency, while increasing the flexibility of the debugging level configuration, thereby saving related human resources and costs.

[0046] In some embodiments, printing a log corresponding to a preset debugging level based on the value of the control data includes: in response to the control data being a first value, printing a log of a first preset debugging level; or in response to the control data being a second value, printing a log of a second preset debugging level.

[0047] In some embodiments, the method further includes: adding a debugging mode control option in the BIOS setting interface to control the turning on or off of the debugging mode.

[0048] In some embodiments, the on state of the debug mode corresponds to a first preset debug level, and the off state of the debug mode corresponds to a second preset debug level.

[0049] The specific embodiment of the BIOS dynamic debugging method of the present invention is as follows:

[0050] a) When compiling the BIOS Image, Enable Debug Mode is enabled by default.

[0051] b) Set the default Debug Error Level (i.e., the first preset debug level) to 0x8100014F, which is used to control the debug level when Debug Mode is turned on.

[0052] c) Add a Debug Error Level of 0x01000000 (the second default debug level), named DEBUG_OEM, which is used to output logs when Debug Mode is turned off.

[0053] d) Added a new option Debug_Mode_Ctrl in the Setup interface to control the on / off of Debug Mode, and the default setting is Disable, which means that Debug Mode is turned off by default.

[0054] f) Select offset 0x4A in CMOS to store Debug Mode control data, and initialize the control data to 0x1 at the initial stage of BIOS POST (BIOS self-test).

[0055] g) In the PEI stage of BIOS initialization, BIOS obtains the value of Debug_Mode_Ctrl under Setup. If Debug_Mode_Ctrl is Disable, the control data in CMOS is set to 0x1 through IO Port (data input / output port) 0x70 / 71; if Debug_Mode_Ctrl is Enable, the control data in CMOS is set to 0x0 through IO Port 0x70 / 71.

[0056] h) In the PrintLog function in DebugLib (debug library), obtain the control data in CMOS.

[0057] i) If the control data is 0x1, DEBUG_OME is returned as the current Debug Error Level; if the control data is 0x0, the default Debug Error Level (0x8100014F) is returned as the current Debug Error Level. The corresponding log is output based on the current debug level.
