Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following describes a method, a device, an electronic device and a medium for updating type information of an SMBIOS table in accordance with the present invention with reference to fig. 1 to 3.
Fig. 1 shows a flow chart of a method for updating type information of an SMBIOS table, and referring to fig. 1, the method includes:
11. Determining a first update type and a second update type on the SMBIOS table; the first update type is a type of which the type information adopts a dynamic update mode; the second update type is a type of which the type information adopts a static update mode;
12. In a DXE starting stage of the BIOS, updating the information of the first update type on the SMBIOS table;
13. determining the reserved byte number of the SMBIOS table;
14. After the DXE boot phase of the BIOS is completed and before entering the OS phase, the information of the second update type on the SMBIOS table is updated based on the reserved byte count and the second update type.
In this regard, it should be noted that, in electronic products such as servers, desktops, notebooks, and mobile phones, management information of the system needs to be checked under an operating system, where the management information includes, but is not limited to, a CPU processor, a memory manufacturer, a memory model, memory location information, a memory rate, system PCI (PERIPHERAL COMPONENT INTERCONNECT, peripheral component interconnect standard) Slot (peripheral component interconnect standard) device information, power supply information, UUID (universal unique identification code) information, system manufacturer, motherboard silk-screen information, motherboard on-board device information, and the like. In short, all information on the motherboard is collected and summarized and updated to an SMBIOS protocol specification table of a BIOS (basic input output system) for recording, so that a user or an operation and maintenance person can quickly and real-timely check the configuration information of the server system, and the configuration of the whole machine can be known without physically touching the server equipment.
According to the SMBIOS protocol specification, the SMBIOS table has two updating modes, namely a dynamic updating mode and a static updating mode, wherein the static updating mode is that the BIOS fills all information of a main board in a system in advance when the BIOS is started, the BIOS fills and updates the information into various types of the SMBIOS protocol when the BIOS is started, but the data are static and cannot be dynamically changed along with the change of the configuration of a server. Therefore, the method of dynamic update dynamically updates the configuration of the motherboard to the type of the SMBIOS table, that is, when the motherboard is started, the BIOS actively identifies the number of CPU processors, CPU rate, CPU core, memory number, memory core, memory manufacturer, PCI slot device number, motherboard on-board device number, system manufacturer, system model, motherboard model, etc. that are related to perform dynamic update, but the byte data length of each type is not fixed. If the reserved bytes are not enough in number or length, the data exceeding the reserved bytes cannot be supported, and the system has serious fatal problems such as error and downtime.
Therefore, the design concept of the method of the invention is to ensure that the reserved byte number meets the length of the updated byte data as much as possible. In contrast, the method of the invention updates some types of information on the SMBIOS table in the DXE (driver execution environment) starting stage of the BIOS, and changes the byte number change caused by the information update in real time by adopting a dynamic updating mode in the DXE starting stage of the BIOS, thereby achieving real-time adaptation byte number change and not occupying reserved byte number.
Note that, the Type information of the specified SMBIOS table based on the protocol may include Bios information (Type 0), system (Type 1), substrate (Type 2), chassis (Type 3), processor information (Type 4), OEM string (Type 11), system configuration option (Type 12), portable battery (Type 22), system power (Type 39), and the like, which are not all described herein.
It is necessary to determine, for each type on the SMBIOS table, which type of information completes the update in the DXE startup phase, which type of information completes the update after the startup phase ends and before entering the OS phase. In this regard, the type information of the first update type is dynamically updated, and the update is completed in the DXE startup phase. The type information of the second update type adopts a static update mode, and the update is completed after the start-up phase is finished and before entering an OS (operating system) phase.
In the DXE startup phase of the BIOS, the first update type of information on the SMBIOS table is updated.
Because the type information of the second update type adopts a static update mode, the reserved byte number is needed to meet the update byte requirement of the type information of the second update type, so that the reserved byte number of the SMBIOS table needed by the information update is firstly determined.
After the reserved byte number is determined, after the DXE startup phase of the BIOS is finished and before entering the OS phase, updating the information of the second update type on the SMBIOS table based on the reserved byte number and the second update type.
After all types of information in the SMBIOS protocol table are updated, calculating SMIOS the total resource requirement of the protocol table and applying for the corresponding memory space so as to enable the system to start the operating system.
According to the type information updating method of the SMBIOS table, the type information is dynamically updated in the DXE starting stage of the BIOS, and the static update of the type information is ensured by the reserved byte number after the starting stage is finished and before the OS stage is entered, so that the resources for updating the SMBIOS protocol table are sufficient, and the problem of system downtime is reduced.
In a further method of the above method, mainly the process of determining the first update type and the second update type on the SMBIOS table is explained, specifically as follows:
Based on a history record of type information updating of the SMBIOS table in a preset time period, obtaining the maximum value of byte number change intervals of each type of information and the updating times of each type of information;
And taking the type with the maximum value larger than the first preset value and the update times larger than the second preset value as a first update type, and taking the rest types except the first update type in the various types of the SMBIOS table as a second update type.
In this regard, it should be noted that for each type on the SMBIOS table, it is necessary to determine which type information completes the update in the DXE startup phase and which type information completes the update after the startup phase is completed and before entering the OS phase. For this reason, it is necessary to select more appropriate type information as the first update type, and perform information update in a dynamic update manner. For information updates of a server, there may be multiple update procedures. At this time, a history of type information update of the SMBIOS table within a certain period of time may be acquired. From this history, the minimum and maximum number of bytes per type of information can be counted, i.e. there is a change in number of bytes. Meanwhile, the update times of each type of information can be obtained. As some types do not have substantial information updates.
For each type of screening, a screening condition may be set, for example, the maximum value is greater than a first preset value, and the number of updates is greater than a second preset value. And taking each type filtered out as a first updating type, and taking other types as a second updating type.
According to the further method, the types with more update changes and more byte changes are reasonably obtained to serve as information update in the DXE starting stage, so that the reserved byte number is not occupied.
In a further method of the above method, the type information includes a plurality of bytes, and there is also a fixed portion of the content presence update included in the entire bytes. That is, the type information of one type can be divided into a first content and a second content, wherein the first content adopts a dynamic update mode and is performed in a DXE startup phase of the BIOS, the second content adopts a static update mode, and after the DXE startup phase of the BIOS is finished and before entering an OS phase, the update is completed in a mode of occupying the reserved byte number.
In the further method of the invention, the dynamically updated content is updated in the DXE startup stage by dividing one type of information content so as not to occupy the reserved byte number.
In a further method of the above method, the process of determining the number of reserved bytes in the SMBIOS table is mainly explained as follows:
acquiring a first byte number of type information of a first update type after updating the information of the first update type on the SMBIOS table;
acquiring the total byte number after the type information on the SMBIOS table is updated last time, the second byte number after the type information of the first updated type on the SMBIOS table is updated last time, and the reserved byte number last time;
and determining the reserved byte number of the SMBIOS table according to the first byte number, the total byte number, the second byte number and the last reserved byte number.
In this regard, it should be noted that in the present invention, the number of reserved bytes is to be determined for the resource requirement of the information update of the second update type. For this reason, the determination of the number of reserved bytes needs to be calculated based on the number of bytes recorded at each angle. For example, the first byte number of the type information of the first updated type after updating, the total byte number after updating the type information on the SMBIOS table last time, the second byte number after updating the type information of the first updated type on the SMBIOS table last time, and the reserved byte number last time are obtained. The reserved byte numbers of the angles are related to the byte numbers generated in the last updating process and the byte numbers generated in the current updating process, so that the reserved byte numbers of the SMBIOS table are calculated in the comprehensive analysis of the byte numbers, and the actual situation of information updating can be matched better.
Further, determining a byte update ratio according to the first byte number and the second byte number;
determining a third byte number based on the total byte number and the second byte number;
Determining a fourth byte count according to the third byte count and the byte update ratio;
and determining the reserved byte number of the SMBIOS table according to the reserved byte number of the last time and the fourth byte number.
And comparing the byte numbers under the same type in the previous and subsequent updating processes to obtain the byte updating proportion. The byte update ratio can represent the size of the change in byte increment or decrement.
And determining a third byte number according to the total byte number and the second byte number, and obtaining the byte number after type updating of the static updating mode. And then determining the fourth byte number by the third byte number and the byte updating proportion, so that the change trend of the byte number after the type updating in the static updating mode can be embodied.
And finally determining the reserved byte number of the SMBIOS table based on the reserved byte number of the last time and the fourth byte number. For example, the last reserved byte number and the fourth byte number are summed or subtracted to obtain the reserved byte number updated this time.
In another embodiment, the process of determining the reserved byte number of the SMBIOS table is as follows:
acquiring a first total byte number and a second total byte number after the type information on the SMBIOS table is updated for the last time and a reserved byte number for the last time;
determining a lifting type based on the two total byte numbers;
and determining the reserved byte number of the SMBIOS table based on the lifting type, the second total byte number and the last reserved byte number.
In this regard, it is to be noted that, from the two adjacent updating processes, it is determined whether the number of bytes between the first total number of bytes and the second total number of bytes is rising or falling. Because the amplitude of the change of the byte number is not larger, namely the byte number after lifting is similar to a larger value or a smaller value, the reserved byte number of the SMBIOS table is calculated according to the second total byte number and the reserved byte number of the last time by carrying out certain lifting design under the lifting trend.
Further, specifically, if the lifting type is an ascending value, determining a fifth byte number based on the second total byte number and a preset descending proportion, and determining the reserved byte number of the SMBIOS table according to the last reserved byte number and the fifth byte number.
And if the lifting type is a descending value, determining a sixth byte number based on the second total byte number and a preset lifting proportion, and determining the reserved byte number of the SMBIOS table according to the last reserved byte number and the sixth byte number.
More specifically, the fifth byte number is removed from the last reserved byte number, so as to obtain the reserved byte number of the SMBIOS table:
And increasing the last reserved byte number by a sixth byte number to obtain the reserved byte number of the SMBIOS table.
In addition, it should be noted that it is difficult to ensure that the determined number of reserved bytes must meet the resources required in the update process, so that the information of the second update type on the SMBIOS table is updated, the number of bytes of the second update type is counted to be greater than the number of reserved bytes of the SMBIOS table, and the number of reserved bytes of the SMBIOS table is optimized based on the counted number of bytes of the second update type. At this time, the update process needs to be stopped, and then, after the new reserved byte number is perfected, the update process is performed again.
In a further method of the above method, configuring an update sequence of the plurality of first update types, and correspondingly, in a DXE startup phase of the BIOS, updating information of the first update type on the SMBIOS table, including:
In the DXE starting stage of the BIOS, based on the updating sequence, respectively acquiring new information of each first updating type, and updating the original information of the first updating type on the SMBIOS table by the new information.
For example, the first update type includes types 0,1, 2, 3,4, 12, 17, 18, 19, 20, 39, and 41.
Before the DXE phase is finished, updating the table types 0, 1,2 and 3 in the SMBIOS protocol, wherein partial character strings of the data existence types 0, 1,2 and 3 are acquired through updating FRU information, and meanwhile, partial information is reserved in the types 0, 1,2 and 3 of the SMBIOS protocol table in advance.
When the types 0, 1,2 and 3 are updated, the type 4 in the SMBIOS protocol table is continuously updated, wherein the type 4 is information of recording the current CPU, including but not limited to CPU manufacturer, CPU model, CPU speed, CPU core number and the like.
After the Type 4 is updated, the Type 12 of the SMBIOS protocol is updated, the Type 12 mainly relates to physical silk screen information of the link between the main board and the peripheral, and after the update is finished, the memory related information, namely types 17, 18, 19 and the like, is updated.
The types 17, 18, 19 of the updated SMBIOS protocol table, the types 17, 18, 19 mainly relate to the memory quantity, memory slot silk screen information, memory capacity, memory manufacturer, memory supported functional characteristics and the like of the current server.
After the memory information of the types 17, 18 and 19 is updated, the type 20 of the SMBIOS protocol table is updated in sequence, and the type 20 mainly records the communication protocol of the BIOS and the BMC.
After the type 20 of SMIOS is updated, the type 39 of the SMBIOS protocol is updated, wherein the type 39 mainly relates to power supply equipment of the server, namely PSU power supply information, including power supply related information such as power supply manufacturer, power supply delivery date, power supply in-place information, power supply position information and the like.
After the type 39 is updated, the type 41 is updated, and the type 41 mainly relates to on-board equipment of the main board, including position information of an on-board storage medium and the like.
In one embodiment, the second update type includes type 9, and after the DXE phase is completed, type 9 information of the SMBIOS protocol is updated, where type 9 is mainly PCI slot information, including but not limited to core information such as slot information, bandwidth information, device location information, and the like of the PCI device. The PCI slot information update of type 9 of the SMBIOS table would also occupy the previously reserved byte count.
In a further method of the above method, mainly the process of determining the first update type and the second update type on the SMBIOS table is explained, specifically as follows:
determining a seventh byte number after the type information of the first update type on the SMBIOS table is updated last time;
determining an eighth byte number based on the seventh byte number and a selection ratio;
Based on the last type number of the first update type on the SMBIOS table, accumulating the byte number of the first update type, and when the current accumulated byte number is equal to or exceeds the eighth byte number, counting a plurality of update types of which the byte number is accumulated as the screened first update type, and classifying the update types of the incomplete accumulated byte number as the second update type.
To reduce the amount of computation on information types during the DXE startup phase of the BIOS, a further reduction may be performed on the plurality of update types selected to obtain less sophisticated types. At this time, the byte count after the last update of the type information of the first update type on the SMBIOS table is needed. A lesser number of bytes may then be determined based on the selected scale. I.e. the eighth byte count is smaller than the seventh byte count.
And then accumulating the byte numbers of the type information of each type one by one, counting a plurality of update types which are accumulated completely as a first update type after screening, and classifying the update type of the incomplete accumulated byte number as a second update type as long as the screened total byte number is reached.
