Description
Technical Field
The present application relates to the field of operating system technologies, and in particular, to an operating system control method and apparatus, a computer motherboard, and a readable storage medium.
Background
The BIOS (Basic Input/Output System), i.e. the Basic Input/Output System, is a bridge or interface between computer hardware and software, and can provide the lowest level hardware control program for the computer. An EC board (EC, Embedded Controller) is a single chip, and an existing EC board has two frameworks, the first is that a FLASH memory of a BIOS is connected to the EC board through a bus, and then the EC board is connected to a south bridge through an LPC bus, in which case a code of the EC board is stored in FLASH, which means that the EC board and the BIOS share one FLASH. The second is that EC board card and FLASH are connected to LPC bus together, the code of EC board card is stored in a FLASH separately and is separated from BIOS.
The BIOS or EC board card is upgraded mainly to start or close functions, such as some requirements customized by a customer or solving some faults caused by compatibility and known bugs of a specific mainboard. However, there are some risks in upgrading the BIOS or the EC board, for example, if the BIOS or the EC board is not matched with the upgrade file, or the motherboard is powered off or powered off during the upgrade process, the motherboard cannot be powered on, and at this time, a professional can only take down the BIOS chip or the EC board and burn the corresponding correct file to be soldered on again.
In practice, some processes for detecting peripheral devices are performed as much as possible by the BIOS, and particularly in industrial control situations, since there are a plurality of peripheral board card devices, different BIOS needs to be performed for different peripheral board card devices to support the functions of the peripheral board card devices. However, this increases the risk of distinguishing and controlling BIOS files, and even brings corresponding influence to the main board and main board maintenance in the factory, for example, if the BIOS file burned in the production process is incompatible with the EC board card required by the client, the BIOS chip needs to be detached and the relevant BIOS file needs to be burned again, otherwise, various strange problems occur, such as slow start, abnormal operation, serious start, and even no start. In the daily maintenance, if a customer wants to upgrade the function of the EC board, and the BIOS of the current motherboard is not compatible with the function of the EC board, the system is down even if the system cannot be powered on due to blind updating. Therefore, the normal operation of the client is affected, and the machine needs to be sent back, disassembled and re-burned with the relevant BIOS file, so that the maintenance time and cost are greatly increased.

Some terms appearing in the embodiments of the present application are explained below.
BIOS, Basic Input/Output System;
the PEI phase and DXE phase are different phases in the BIOS boot process, respectively, where a PEI (Pre-EFI Initialization) phase is mainly used to initialize a memory and prepare an execution environment for a next DXE phase. The DXE phase is primarily used to drive the execution environment.
ECSCI is a PIN on the EC board that requests an interrupt, specified by BIOS, and reported to the operating system via ACPI (Advanced Configuration and Power Management Interface). Such as reporting of battery information, reporting of temperature, brightness adjustment requests, and screen switching, all require such interrupts to notify the operating system to execute.
The LPC Bus, Low pin count Bus, is a Bus commonly used in Low speed devices, where the LPC Bus is typically physically connected to the south bridge on the motherboard.
ASL (ACPI Source language) is a specialized language for writing tables of ACPI (advanced Configuration and Power interface), and ACPI mainly functions to provide some services of the operating system and some messages to the operating system, and ASLCODE is executed by the operating system after being compiled by a compiler.
The BIOS ASL file is a file of which one file type is ASL in a source code of the BIOS, and is mainly used for services such as information interaction between the BIOS and an operating system.
Example 1
Referring to fig. 1, the present embodiment provides an operating system control method, which is applied to a computer motherboard, such as an industrial motherboard, and the like, and the motherboard adopting the method can implement different usage scenarios with and without requirements on an EC board, and particularly can solve the problem that some BIOS and EC boards are incompatible and are still updated, so that a system is not available, and the like.
Exemplarily, the operating system control method includes:
in step S110, the BIOS performs a power-on self-test operation.
When the mainboard is powered on and started, the CPU is activated and then searches for a first instruction address of the BIOS, and then the BIOS is operated, namely the BIOS performs power-on self-test and system boot operation. Exemplarily, the BIOS first establishes a BIOS code execution working environment, then initializes a chip (such as a north-south bridge) and a memory on a motherboard, and scans an external device (including a mouse keyboard, a serial port, a network card, a hard disk, a display device, and the like). And if the equipment is not interrupted in the starting process, entering an operating system until all the equipment on the mainboard is initialized. The power-on self-test operation mainly refers to detecting whether the hardware part of the computer is good or not when the power is just switched on.
Step S120, activating a preset address allocated to the EC board, and performing initialization configuration on a preset GPIO port for requesting interrupt by the EC board.
In order to avoid the phenomena that the EC board is carried on the mainboard of the BIOS incompatible EC board, which causes the system to slow down, the operation is abnormal, even the system cannot be started, and the like, in the embodiment, the BIOS activates the designated address which is used for being allocated to the EC board in advance and initializes and configures the preset GPIO port for requesting the interruption of the EC board in the PEI stage, so that the EC board can be normally accessed and operated in the subsequent stage when the EC board is determined to be carried currently.
The designated address is mainly used for being allocated to the EC board card to access the related data. In one embodiment, the activating operation may include setting a status bit used for a specific address allocated to the EC board card to be in an on state in advance, and then allocating a corresponding storage space to the specific address whose status bit is in the on state. It can be understood that when the EC board does not need to be loaded, the state bit of the designated address is in a closed state, and the address is inaccessible in the closed state; when the EC board needs to be loaded, the specified address will be allocated to the EC board for use, at this time, the state of the specified address will be set to an on state, and a corresponding address storage space will be allocated for storage of data related to the EC board, and the like. The GPIO port is a pin corresponding to the ECSCI, and is mainly used to receive a system interrupt signal requested by the EC board when the EC board is mounted.
It can be understood that when the motherboard needs to carry the EC board, a corresponding address is usually set and a corresponding GPIO port is allocated to request system interrupt by the EC board, so as to access the EC board.
As an optional scheme, after the BIOS performs the power-on self-test operation, it may also first detect whether there is a preset address used by the EC board, and if so, perform a decoding operation on the preset address; otherwise, if the program does not exist, the program can be directly guided into the system to complete the starting operation of the mainboard.
Step S130, an identification value is set for the EC register value, and the address obtained by decoding is accessed.
Exemplarily, the BIOS may set an identifier Flag to a register value of an EC board card that may exist in the DXE phase, then access the address obtained by the parsing through the LPC bus, and determine whether the actual EC board card is currently loaded on the motherboard according to whether the register value obtained by actual access is the same as the Flag value. Different values of Flag are used for representing different EC board card carrying states, for example, the value of Flag may be set to 0 or 1, where a state that an EC board card is currently connected is indicated when Flag is 1, and a state that an EC board card is not currently connected is indicated when Flag is 0. It should be understood that the value of Flag is not limited to 1 and 0, and may be other values as long as different values can distinguish different carrying states of the EC board.
And step S140, determining whether the main board is currently loaded with the EC board card according to the identification value and the accessed EC register value.
For example, in an embodiment, if the obtained EC register value is the same as the Flag value, that is, the obtained matching Flag value indicates that the EC register value is obtained, then it is determined that the EC board is currently mounted on the motherboard. Otherwise, if the obtained EC register value is different from the identification value, that is, it indicates that the matched Flag value is not obtained, it is determined that the EC board card is not currently mounted. Further, when it is determined that the EC board is not mounted, step S150 is executed; if it is determined that the EC board is mounted, step S160 is executed.
And step S150, the initialization of the preset GPIO port and the data access of the EC board card are closed.
For the first case, when it is determined that the EC board is not mounted, exemplarily, the BIOS turns off the GPIO function corresponding to the ECSCI initialized in the PIE stage before the initialization, and also turns off the data access to the EC board, and then enters the system according to the normal boot program, that is, jumps to step S180.
And step S160, initializing a preset GPIO port and accessing data of the EC board card.
For the second case, when it is determined that the EC board is loaded, the BIOS may continue to initialize the preset GPIO port configured in the PIE stage, specifically, set the GPIO port to receive the system interrupt request of the EC board, that is, configure the GPIO port as an SCI function. Afterwards, the BIOS can access data to the EC board card.
And step S170, successfully loading and configuring functions which need to be realized by the EC board card.
As shown in fig. 2, exemplarily, after performing step S160, step S170 includes:
step S190, loading a function that needs to be implemented by the EC board based on the aslmode, and detecting whether the corresponding BIOS ASL file is loaded with the identification value.
In view of the fact that some BIOS may not be compatible with the EC board, in this embodiment, after the relevant functions to be implemented by the EC board are loaded, it is further required to detect whether the loading is successful, so as to determine whether to further close the relevant functions to be implemented by the EC board.
Illustratively, when data access to the EC board is allowed, the BIOS may load the relevant functions to be implemented by the EC board using ASLCODE, where successfully loaded data is stored in the BIOS ASL file. Then, if the value loaded to Flag in the BIOS ASL file is detected, step S200 is executed, otherwise step S210 is executed.
Step S200, if the identification value is loaded, the functions to be realized by the EC board card are correspondingly configured in the BIOS ASL file.
Step S210, if the identification value is not loaded, closing the function that needs to be implemented by the EC board in the BIOS ASL file.
On the contrary, if it is detected that loading the Flag value in the BIOS ASL file fails, the functions that the EC board needs to implement need to be prohibited to be configured, so as to avoid situations such as downtime and dead halt before entering the system.
Step S180, the system is booted.
Therefore, after the BIOS successfully loads and configures the function that the EC board needs to implement, normal boot is performed to enter the system. It can be understood that the BIOS can be compatible with the situations that the EC board is not loaded and the EC board is loaded at the same time by the above processing operations on two different situations, and different use scenarios are satisfied.
The operating system control method of the embodiment can be applied to a scene where an EC board can be carried or an EC board is not carried, the address of the EC board is decoded, GPIO corresponding to ECSCI is initialized, a Flag is established for an EC register value to further determine whether the current motherboard is connected with the EC board, and then whether the function which needs to be implemented by loading the EC board is needed is determined again by the Flag to determine whether the function of the EC board needs to be loaded, and when the loading is unsuccessful, the function is immediately turned off to avoid the situation that the system cannot be normally turned on. According to the method, corresponding judgment is carried out in different processing operations, so that the phenomena of downtime, system incapability and the like caused by the incompatibility problem of the EC board card are avoided, synchronous compatibility of customers requiring the EC board card function and customers not requiring the EC board card function can be realized, more time can be saved for the customers, the use efficiency can be improved, and the like.
