Detailed Description
The core of the application is to provide a serial port card communication implementation method, a device, equipment and a computer readable storage medium, which are used for enabling the serial port card to be used in normal communication.
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, which shows a flowchart of a serial port card communication implementation method provided in an embodiment of the present application, the serial port card communication implementation method provided in the embodiment of the present application, applied to a BIOS, may include:
s11: judging whether the operating system successfully loads the drive of the serial port card; if not, step S12 is executed, and if yes, step S13 is executed.
Inserting a serial port card into a server, powering on the server, installing a serial port card driver, and executing a corresponding running script (specifically, a start script) to run the serial port card. It should be noted that the CPU architecture in the server may be an ARM architecture (at this time, the boot method defaults to UEFI) or other architectures as long as the architectures can recognize the inserted serial port card. The serial port card mentioned here may be a PCIE (Peripheral Component Interconnect express, a high speed serial computer extended bus standard) serial port card or a PCI (Peripheral Component Interconnect, or the like.
In the process of starting up and initializing the server, because the BIOS (Basic Input/Output System ) may obtain information related to the driver of the serial port card, the BIOS may determine whether the operating System successfully loads the driver of the serial port card, and if it is determined that the operating System does not successfully load the driver of the serial port card, it indicates that the serial port card cannot normally communicate and use, at this time, step S12 may be performed, and if it is determined that the operating System successfully loads the driver of the serial port card, it indicates that the serial port card can subsequently run, at this time, step S13 may be performed.
S12: and loading a drive for the serial port card according to the drive information which is registered in advance and corresponds to the serial port card, and distributing corresponding resources for the serial port card so that the serial port card utilizes the resources to carry out communication.
If the operating system is determined not to successfully load the drive of the serial port card, the BIOS calls drive information which is registered in advance and corresponds to the serial port card, the called drive information is registered in the serial port card to load the drive for the serial port card, and after the drive is loaded for the serial port card, the BIOS directly distributes resources to the serial port card through the logic interruption of the CPU, so that the serial port card can utilize the distributed resources to carry out communication, namely, the serial port card can be normally used. The above-mentioned pre-registered drive information includes, but is not limited to, bus (bus), dev (device), and fun (function) information of the serial port card, and the information may be pre-registered in the BIOS for subsequent direct retrieval and use by the BIOS.
S13: judging whether the serial port card is distributed to corresponding resources or not; if not, step S14 is executed.
If the operating system is determined to successfully load the driver of the serial port card, it indicates that the serial port card can run (i.e. the driver of the serial port card can be loaded normally). After initialization is completed and the serial port cards run, the BIOS can perform polling monitoring on each serial port card, judge whether the serial port cards are allocated with corresponding resources during running through the polling monitoring, and if the serial port cards are determined to be allocated with the corresponding resources, the serial port cards can be normally communicated and used; if it is determined that the serial port card is not allocated to the corresponding resource, step S14 is executed.
S14: and loading a drive for the serial port card according to the drive information, and distributing corresponding resources for the serial port card.
If the BIOS determines that the serial port card is not allocated to the corresponding resource, the serial port card cannot be normally communicated and used, and at this time, a problem may occur in driver loading of the serial port card, and a problem may also occur in resource allocation of the serial port card. Considering that after the initialization is completed, the BIOS cannot scan and acquire information related to the driver of the serial port card to determine whether the operating system successfully loads the driver of the serial port card, and therefore, after it is determined that the serial port card is not allocated with the corresponding resource, the BIOS directly loads the driver for the serial port card according to the driver information which is registered in advance and corresponds to the serial port card, and allocates the corresponding resource to the serial port card, so that the serial port card can communicate by using the allocated resource, that is, the same step as step S12 can be performed.
Specifically, the process of loading the driver for the serial port card by the BIOS according to the driver information that is registered in advance and corresponds to the serial port card is the same as the specific implementation of the step S12, that is, the BIOS calls the driver information that is registered in advance and corresponds to the serial port card, registers the called driver information in the serial port card to load the driver for the serial port card, and after loading the driver for the serial port card, may allocate the resource in the CPU corresponding to the serial port card, so that the serial port card can communicate using the allocated resource.
According to the process, the technical scheme that the BIOS is used for automatically identifying and assisting the operating system to allocate resources and the BIOS is used for allocating resources when the drive cannot be loaded is adopted, and the condition that the serial port card cannot be used can be effectively avoided. If the serial port card is adapted in the non-X86 architecture, the BIOS is hardly influenced by the architecture and the mode, so the serial port card can normally communicate and use in the non-X86 architecture through the process; if the serial port card is adapted in the X86 architecture, the BIOS may replace the os to provide services for the communication of the serial port card in case the os cannot load a driver and/or allocate resources to the serial port card, so that the serial port card can communicate normally.
According to the technical scheme disclosed by the application, when the BIOS determines that the operating system does not successfully load the drive of the serial port card or the serial port card is not allocated with the corresponding resource although the operating system successfully loads the drive of the serial port card, the BIOS loads the drive for the serial port card according to the drive information which is registered in advance and corresponds to the serial port card, and allocates the corresponding resource for the serial port card after the drive is loaded, so that the serial port card can communicate by using the resource allocated to the resource, namely when the operating system cannot realize the communication of the serial port card, the BIOS is used for realizing, and the BIOS is hardly influenced by the mode, so that the serial port card can normally communicate and use in an X86 architecture or a non-X86 architecture, and the reliability and universality of the use of the serial port card are improved.
Referring to fig. 2, a flowchart of another method for implementing serial port card communication according to an embodiment of the present application is shown. The method for implementing serial port card communication provided in the embodiment of the present application, after allocating corresponding resources to the serial port card, may further include:
s15: judging whether the operating system allocates corresponding resources for the serial port card; if yes, go to step S16, otherwise, go back to step S13;
s16: the allocation of the corresponding resources to the serial port card is stopped, and step S13 is performed.
After allocating the corresponding resources to the serial port card, the BIOS determines whether the operating system allocates the corresponding resources to the serial port card, and if it is determined that the operating system allocates the corresponding resources to the serial port card, the BIOS stops allocating the corresponding resources to the serial port card, that is, the operating system is only used to allocate the corresponding resources to the serial port card, so as to avoid the occurrence of a situation of resource repeated allocation, thereby avoiding resource waste, and avoiding a conflict that the serial port card occupies the resources due to the operating system and the BIOS allocating the resources to the serial port card at the same time. In addition, after stopping allocating the corresponding resource to the serial port card, the BIOS may return to step S13, that is, continuously monitor the serial port card, so as to find the abnormality of the serial port card in time and handle the abnormality of the serial port card in time, thereby enabling the serial port card to be used in normal communication.
When step S15 is executed, if the BIOS determines that the operating system does not allocate corresponding resources to the serial port card, it indicates that only the BIOS is allocating resources to the serial port card at this time, and there is no situation of resource repeated allocation, so the BIOS may directly return to step S13 to continuously monitor the serial port card, thereby facilitating to find the abnormality of the serial port card, and timely handle the abnormality of the serial port card, so that the serial port card can be used for normal communication.
The method for implementing serial port card communication provided in the embodiment of the present application, determining whether an operating system allocates a corresponding resource to a serial port card, may include:
judging whether the occupation amount of resources corresponding to the serial port card in the CPU is increased or not;
and if so, determining that the operating system allocates corresponding resources for the serial port card.
When determining whether the operating system allocates the corresponding resource to the serial port card, it may specifically be determined whether an occupied amount of the resource corresponding to the serial port card in the CPU is increased, where the increase is relative to the occupied amount when the BIOS allocates the resource corresponding to the serial port card.
If the occupation amount of the resources corresponding to the serial port card in the CPU is determined to be increased, the resources corresponding to the serial port card are indicated to be repeatedly occupied, namely the operating system is determined to be recovered to be normal and the resources corresponding to the serial port card are distributed, and if the occupation amount of the resources corresponding to the serial port card in the CPU is determined not to be increased, the resources corresponding to the serial port card are indicated not to be repeatedly occupied, namely the operating system is determined not to distribute the resources corresponding to the serial port card.
The mode of determining whether the operating system allocates the corresponding resources to the serial port card by judging whether the occupation amount of the resources is increased can be directly and efficiently determined.
The method for implementing serial port card communication provided in the embodiment of the present application, determining whether a serial port card is allocated to a corresponding resource, may include:
judging whether a resource corresponding to the serial port card in the CPU is occupied or not;
and if so, determining that the serial port card is allocated to the corresponding resource.
When judging whether the serial port card is allocated with the corresponding resource, the BIOS may implement the determination by judging whether the resource corresponding to the serial port card in the CPU is occupied, specifically, if the resource corresponding to the serial port card in the CPU is occupied, it is determined that the serial port card is allocated with the corresponding resource, and if the resource corresponding to the serial port card in the CPU is unoccupied, it is determined that the serial port card is not allocated with the corresponding resource, which facilitates directly and efficiently determining whether the serial port card is allocated with the corresponding resource.
In the method for implementing serial port card communication provided in the embodiment of the present application, if the serial port card is connected to a communication device, it is determined whether the serial port card is allocated to a corresponding resource, which may include:
judging whether the serial port card is in normal communication with the communication equipment or not;
and if so, determining that the serial port card is allocated to the corresponding resource.
In this application, if the serial port card is connected with a communication device, the manner of determining whether the serial port card allocates the corresponding resource may be: judging whether the serial port card is normally communicated with the connected communication equipment, if the serial port card is normally communicated with the connected communication equipment, indicating that the serial port card can be normally communicated and used, determining that the serial port card equipment is allocated with corresponding resources, if the serial port card is not normally communicated with the connected communication equipment, indicating that the serial port card cannot be normally communicated and used, and at the moment, determining that the serial port card equipment is not allocated with the corresponding resources.
The judging mode can be convenient for directly and accurately judging whether the resources are distributed or not, thereby being convenient for improving the reliability of realizing the serial port card communication.
In the method for implementing serial port card communication provided in the embodiment of the present application, if it is determined that the serial port card is allocated to the corresponding resource, the method may further include:
and returning to execute the step of judging whether the serial port card is allocated to the corresponding resource.
In this application, when step S13 is executed, if it is determined that the serial port card is allocated to the corresponding resource, it indicates that the serial port card can communicate and use normally, at this time, while the serial port card is used normally, the BIOS may continue to perform polling monitoring on the serial port card, determine whether the serial port card is allocated to the corresponding resource, and return to step S13, so as to find out that the serial port card is abnormal in time, and facilitate processing according to step S14 when the abnormality is found, thereby ensuring that the serial port card can allocate the resource, and further enabling the serial port card to be used normally.
