Description

Technical Field

[0001] The present application relates to the field of server technology, and in particular to a system management memory allocation method, a program running method, a system and a product. Background Art

[0002] In the server field, memory management is very important. With the continuous development of computer technology and the increasing complexity and diversification of its applications, the functions of BIOS (Basic Output Input System), as a key part of computer startup and hardware initialization, are constantly expanding and optimizing, and the system's demand for memory resources is also increasing. Traditional BIOS memory management methods often adopt static allocation strategies, and the configuration of memory size is often relatively fixed, that is, a fixed memory size is allocated according to the preset value when the system starts. The method of allocating a fixed memory size is more likely to lead to insufficient memory when the system is highly loaded, and memory resources are not fully utilized when the system is underloaded, which cannot meet the user's flexible adjustment needs for memory size in different application scenarios.

[0003] In addition, with the innovation of new BIOS technologies, SDU (SMM Driver Update) technology has been introduced in recent years. This technology can update BIOS area modules in real time under the system through the SMM (System Management Mode) service resident in the BIOS. SDU technology uses the SMRAM (System Management RAM) area to implement module access, which makes the allocable area in SMRAM tight. On this basis, the number of allocable memory pages in the SMRAM area is directly related to the implementation of SDU technology.

[0004] In a server, the more physical processors and cores a single processor has, the more memory pages it occupies in the system management mode. If the allocatable memory pages in the SMRAM area are insufficient to support the operation of the SDU, a failure will occur. Therefore, how to achieve flexible memory allocation to meet the normal operation of the SDU is a problem that needs to be solved. Summary of the invention

[0066] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0067] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0068] In the various embodiments of the present application, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0069] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects as detailed in the present application.

[0070] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0071] The traditional SMRAM memory allocation method is to allocate a fixed size of memory capacity. However, as the number of physical processors and the number of processor cores increase, the memory required to execute SDU services also increases, and insufficient memory may occur, causing the SDU service to fail to operate normally. For example, on a two-way processor server or a four-way processor server, when updating the BIOS area module through SDU technology, less than 600 memory pages are usually required, and the fixed allocation of 128M SMRAM capacity can meet the needs. However, for the case of a large number of cores, including a 48-core processor server, the number of memory pages required by the server reaches 1,300 memory pages. At this time, the fixed allocation of 128M SMRAM memory space is not enough to support the normal operation of the SDU, and a failure will occur. For engineers, blindly expanding SMRAM memory may lead to potential memory risks and system insecurity. For example, allocating too much SMRAM memory to meet the operation of the SDU may cause some applications to run out of memory during operation.

[0072] Therefore, the SMRAM memory allocation method provided by this application flexibly allocates memory capacity that matches the number of cores according to the number of processing cores in the server, thereby reducing memory risks on the basis of meeting the operating requirements of the SDU. This solution can be applied to server platforms of various architectures to achieve adaptive allocation of SMRAM memory based on the actual configuration of the server to meet the needs of the normal operation of the server SDU.

[0073] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0074] Figure 1 1 is a flow chart of a system management memory allocation method proposed in an embodiment of the present application. Figure 1 As shown, the method includes:

[0075] S1: Start the basic input and output system, initialize the system management mode environment and configure the system management mode service;

[0076] S2: Obtain the number of physical processors on the server and the number of cores carried by each physical processor, and calculate the total number of cores;

[0077] S3: determining a corresponding core interval based on the total number of cores, and determining a first target capacity of a system management memory to be configured based on the core interval;

[0078] S4: Based on the first target capacity, allocating system management memory for driver update in system management mode.

[0079] In this embodiment, during the server startup process, the BIOS is first run. After entering the BIOS, the SMM environment is initialized and the SMM service is configured. During the BIOS POST (Power On Self Test), the memory usage is collected in real time, the number of physical processors of the current server and the number of cores of each physical processor are detected, and then the total number of cores in the current server is calculated:

[0080] Total core count = the sum of the core counts of all physical processors.

[0081] Further, according to the current total number of cores of the server, the corresponding core interval is determined, and then the SMRAM memory capacity (ie, the first target capacity) to be allocated for the SDU service is determined. Based on the first target capacity, the SMRAM memory is allocated to complete the allocation of the system management memory.

[0082] This application determines the total number of cores in the current server in real time during the server startup process, thereby allocating a matching SMRAM memory capacity to the server to meet the normal operation of the SDU service after the server is powered on. This method can be used to automatically match servers with different hardware configurations and allocate SMRAM memory of appropriate capacity. The automated memory adjustment process reduces the need for manual intervention and reduces the maintenance cost and time cost of the system. By reasonably allocating SMRAM memory capacity, it is possible to avoid memory waste caused by excessive memory allocation, or the inability of the SDU to operate normally after startup due to too small memory allocation, so that the system can use memory resources more efficiently and improve the overall system performance. This method can significantly improve the computer's ability to flexibly adjust SMRAM memory allocation, thereby meeting performance requirements in specific application scenarios.

[0083] As an implementation manner of the present application, the system management memory allocation method further includes:

[0084] After allocating system management memory, run the operating system;

[0085] The driver update service is run in the system management mode in the operating system to update the basic input and output system area module of the server; the basic input and output system area module is a part of the program in the basic input and output system firmware.

[0086] In one embodiment, after the system management memory is allocated, the system enters the operating system. In the operating system, the SDU is executed through the SMM service, so as to update some area modules in the BIOS firmware and check the verification operation results.

[0087] As an implementation manner of the present application, determining a corresponding core interval based on the total number of cores, and determining a first target capacity of a system management memory to be configured based on the core interval includes:

[0088] comparing the total number of cores to a first threshold;

[0089] When the total number of cores is less than or equal to the first threshold, determining the corresponding core interval as a first interval;

[0090] Based on the first interval, a first target capacity of the system management memory to be configured is determined as the first capacity.

[0091] In one embodiment, based on the total number of cores of the current server, the interval in which the total number of cores is located is determined. Specifically, the total number of cores is compared with a first threshold value, and if the total number of cores is less than or equal to the first threshold value, it is determined that the total number of cores is in the first interval. In this embodiment, a plurality of intervals of the number of cores are pre-divided based on the threshold value, and the corresponding memory capacity to be allocated is matched to each interval. When the total number of cores of the server is less than or equal to the first threshold value, it is determined that the current interval is within the range of the first interval. Further, the first capacity matching the first interval is determined to be the first target capacity allocated to the server, that is, the SMRAM memory capacity used as the SDU running the server.

[0092] In actual applications, the first threshold and the first target capacity can be customized according to actual application needs. In this embodiment, the first threshold can be set to 256, and the first target capacity can be set to 128M. That is, when the total number of cores of the server does not exceed 256, 128M of SMRAM memory capacity is allocated to the SDU.

[0093] As an implementation manner of the present application, determining a corresponding core interval based on the total number of cores, and determining a first target capacity of a system management memory to be configured based on the core interval further includes:

[0094] When the total number of cores is greater than the first threshold, comparing the total number of cores with a second threshold; the second threshold is greater than the first threshold;

[0095] When the total number of cores is less than or equal to the second threshold, determining the corresponding core interval as the second interval; based on the second interval, determining that the first target capacity of the system management memory to be configured is the second capacity; the second capacity is greater than the first capacity;

[0096] When the total number of cores is greater than the second threshold, the corresponding core interval is determined to be a third interval; based on the third interval, a first target capacity of the system management memory to be configured is determined to be a third capacity; and the third capacity is greater than the second capacity.

[0097] In one embodiment, if the total number of cores of the current server is greater than the first threshold, the total number of cores is further compared with the second threshold. If the total number of cores is less than or equal to the second threshold, it is determined that the total number of cores of the server is within the range of the second interval. Further, the second capacity matching the second interval is determined to be the first target capacity allocated to the server, that is, the SMRAM memory capacity used for the server to run the SDU.

[0098] If the total number of cores is greater than the second threshold, it is determined that the total number of cores of the server is within the range of the third interval. Further, a third capacity matching the third interval is determined as the first target capacity allocated to the server, that is, the SMRAM memory capacity used for running the SDU of the server.

[0099] In actual applications, the second threshold, the second capacity, and the third capacity can all be customized according to actual application needs. Optionally, the second threshold is set to 512, and the second capacity is set to 256M. That is, when the total number of cores of the server exceeds 256 and does not exceed 512, 256M of SMRAM memory capacity is allocated to the SDU. The third capacity is set to 512M, that is, when the total number of cores of the server exceeds 512, 512M of SMRAM memory capacity is allocated to the SDU.

[0100] In this embodiment, the total number of cores of the server is first compared with the minimum threshold (i.e., the first threshold). When the total number of cores is less than the first threshold, the memory capacity to be allocated is directly determined, thereby saving system resources. When the total number of cores of the server exceeds the first threshold, the total number of cores is further compared with a second threshold that is larger than the first threshold, thereby determining the range interval in which it is located.

[0101] As an implementation manner of the present application, allocating system management memory based on the first target capacity includes:

[0102] Acquire current free memory pages, and allocate a corresponding number of free memory pages based on the first target capacity;

[0103] After allocating the free memory page, detecting whether there is a memory page conflict between the currently allocated free memory page and the memory page occupied by the hardware device of the server;

[0104] If there is a memory page conflict, the memory pages occupied by the hardware device of the server are set as reserved memory, and the free memory pages are reallocated.

[0105] In one embodiment, after determining the first target capacity of the SMRAM memory to be allocated, the free memory pages in the memory are obtained, so as to allocate a corresponding number of free memory pages according to the first target capacity. After each adjustment of the memory page, it is necessary to detect whether the memory page currently allocated for the SDU service conflicts with the memory page allocated for other hardware devices in the server. If a conflict occurs, it is necessary to set the memory page allocated by the system for other hardware devices (for example: PCIE card, network card, video card, etc.) to Reserve mode (i.e., retain memory), and then re-detect the allocable free memory pages, and reallocate the free memory pages for the SDU service. Avoid memory conflicts that cause the service to fail to operate normally after startup.

[0106] In this embodiment, when allocating SMRAM memory for SDU services, it is detected in real time whether there is overlap with the addresses (memory pages) occupied by other devices, so that the area position is readjusted, avoiding potential system security risks and instability, and also achieving compatibility with other devices and system configurations.

[0107] As an implementation manner of the present application, after determining the first target capacity of the system management memory to be configured, the method further includes:

[0108] Check whether there is a pre-set expansion configuration;

[0109] If there is a pre-set capacity expansion configuration, read the capacity expansion configuration to obtain the second target capacity;

[0110] Based on the first target capacity and the second target capacity, a system management memory is allocated.

[0111] In one embodiment, in addition to allocating memory to the SDU, SMRAM memory can also be allocated to some specified applications that run after booting. The memory of the application is allocated by means of expansion configuration. In the BIOS stage, after determining the first target capacity to be configured, check whether there is a pre-set expansion configuration in the BIOS. If there is an expansion configuration, read the expansion configuration and obtain the second target capacity to be expanded. Based on the first target capacity and the second target capacity, determine the total capacity to be allocated:

[0112] Total capacity = first target capacity + second target capacity.

[0113] In this embodiment, the user can pre-set the expansion configuration according to the SMRAM memory capacity required by the specified application. When the server is powered on and enters the POST stage, the total number of cores of the server is first obtained by real-time detection, and then the corresponding first target capacity is automatically matched according to the total number of cores, and memory is allocated to the SDU service based on the first target capacity. In addition, it is detected whether there is a pre-set expansion configuration. If so, the expansion configuration is read and the second target capacity is obtained therefrom, and memory is allocated to the application based on the second target capacity. That is, in this embodiment, the total capacity of the SMRAM memory allocated in the BIOS stage is determined based on the first target capacity and the second target capacity.

[0114] In this embodiment, for certain applications that need to use SMRAM memory, memory is allocated by pre-setting the expansion configuration, so that memory expansion can be implemented on the basis of allocating memory for SDU services in the BIOS stage, so that the normal operation of SDU services and specified applications can be met after the boot is completed.

[0115] As an implementation manner of the present application, the system management memory allocation method further includes:

[0116] Displaying optional expansion configurations on a basic input / output system settings interface; the expansion configurations include: expandable capacity options;

[0117] When the expansion configuration is changed, a basic input and output system restart operation is performed.

[0118] In one embodiment, the optional expansion configuration is displayed on the BIOS setup interface, including at least one expandable capacity option. The user can generate the expansion configuration by presetting the expansion memory capacity in the BIOS setup interface and submitting it for saving. In the case where the expansion configuration changes, the BIOS executes a restart and reads the pre-set expansion configuration after the next startup to obtain the second target capacity therein.

[0119] It is worth noting that since setting the SMRAM memory too large can easily cause memory waste, when setting the expansion configuration, it is necessary to ensure that the total capacity determined based on the first target capacity and the second target capacity usually does not exceed the capacity threshold. In one embodiment, when displaying the optional expansion configuration in the BIOS setup interface, the expandable capacity options can be screened according to the capacity threshold and the first target capacity, and the optional options that meet the capacity threshold conditions are marked and displayed as recommended expanded memory capacity for the user to choose.

[0120] For example, in the BIOS setup interface, there are three capacity options: 32M, 64M, and 128M. When the capacity threshold is 560M, if the first target capacity is 512M, the 32M capacity option is marked as a recommended option for display; if the first target capacity is 128M, the 32M, 64M, and 128M capacity options are all marked as recommended options. By marking the capacity options that meet the capacity threshold conditions as recommended options and displaying them in the BIOS setup interface, users can give priority to recommended options when making choices, avoiding memory waste and improving overall system performance.

[0121] As an implementation mode of the present application, after allocating the system management memory, it also includes: before entering the operating system, the current system management memory real-time operating status information and memory usage information are displayed on the user interface.

[0122] In one embodiment, in order to facilitate the user to understand the adjustment process of the system memory, after the memory configuration is completed, the real-time operation status of the system management memory and the memory usage are also displayed on the user interaction interface for the user to view. This facilitates the user to intuitively understand the memory allocation, including: the address, size and area attributes of the current SMRAM and other information.

[0123] Figure 2 1 is a flowchart of allocating system management memory in one embodiment of the present application. Figure 2As shown, after booting and entering the BIOS, the system management mode (SMM) environment is first initialized, and then the system management mode (SMM) service is configured. The number of physical processors in the current server and the number of cores of each physical processor are detected, and the total number of cores of the current server is calculated. According to the total number of cores, the first target capacity to be allocated is determined. Whether there is a pre-set expansion configuration is detected. If not, the memory is directly allocated based on the first target capacity. If it exists, the expansion configuration is read to obtain the second target capacity to be expanded. The total capacity is obtained based on the first target capacity and the second target capacity, and the system management memory (SMRAM) is allocated. After the memory is allocated, it is detected whether there is a conflict with the memory page occupied by the hardware configuration in the server (overlap occurs). If there is an overlap, the memory page occupied by the hardware configuration is set as reserved memory, and then the free page is re-allocated based on the total capacity. After the memory allocation is completed, before running the operating system, the real-time operating status and memory usage of the system management memory are displayed on the user interface for users to view. After running into the operating system, the SDU or the specified application can be run normally.

[0124] Based on the same inventive concept, an embodiment of the present application provides a program running method, including:

[0125] Execute the system management memory allocation method described in the above embodiment, allocate system management memory, and run the operating system;

[0126] After entering the operating system, running the target application; the target application occupies the system management memory when running;

[0127] When insufficient memory occurs during the operation of the target application, obtaining the system management memory capacity that needs to be expanded for the target application;

[0128] Restart the server to enter the basic input and output system setting interface, and set the expansion configuration in the basic input and output system setting interface according to the system management memory capacity that needs to be expanded;

[0129] After setting the expansion configuration, restart the server, and execute the system management memory allocation method as described in the above embodiment to allocate the system management memory;

[0130] After allocating system management memory, run the operating system;

[0131] After entering the operating system, the target application is re-run.

[0132] In this embodiment, after the system is powered on, the target application that needs to use SMRAM memory is run. In practical applications, the target application can be part of the developer tool program (for example, debug program). Since the application can only run in the operating system, it is impossible to determine whether the currently allocated memory capacity meets the normal operation of the target application in the BIOS stage of the server startup. Therefore, in the BIOS stage, the corresponding memory is first allocated to the SDU service through the above-mentioned system management memory allocation method. After entering the operating system, the target application is run. If insufficient memory occurs during the operation of the target application, the memory capacity required by the program will be prompted by a fault error. Then, the capacity expansion is performed according to the memory capacity required by the program. Specifically, the server is restarted to enter the BIOS.
