[0002] During the normal startup process of an electronic device, it is usually necessary to load firmware and operating system into its board. The firmware runs first, and then the system kernel is guided directly or indirectly to load the complete operating system to complete the startup of the electronic device. When booting the system kernel, some parameters need to be passed to the system kernel.

[0003] In the related art, there are multiple parameter passing methods for passing parameters to the system kernel. When writing the system kernel program, the corresponding parameter parsing and receiving methods are set according to the parameter passing method adopted by the board hardware it needs to run, so as to ensure the normal operation of the system kernel on the electronic device.

[0004] However, the firmware is usually burned into the corresponding Flash chip before leaving the factory.

It should be understood that the data used in this way can be interchangeable when appropriate, so that the embodiments of the present invention can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, the term "and / or" in the specification and claims is used to describe the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. In the embodiments of the present invention, the term "multiple" refers to two or more, and other quantifiers are similar.

[0070] Figure 1 A flow chart showing a parameter transfer method embodiment of the present invention is shown, which is applied to electronic equipment. The method may include the following steps:

[0071] Step 101: store first parameter data transmitted to a system kernel in a memory, and store a first parameter transmission mode mark of the first parameter data in a first preset storage space.

[0072] When the electronic device is started, the board is usually powered on first. After the board is powered on, the firmware stored in the non-volatile memory such as ROM and EPROM in the board will be loaded first, and then the firmware will directly guide the system kernel to load the operating system, or indirectly guide the system kernel to load the operating system through the boot loader. The system kernel may include but is not limited to Linux Kernel, FreeBSD Kernel, OpenBSD Kernel, etc., and the embodiment of the present invention does not specifically limit it.

[0073] In order to correctly guide the system kernel to load the operating system, it is usually necessary to pass the first parameters to the system kernel (kernel), and these first parameters may include but are not limited to hardware description information, system configuration information, hardware configuration information, hardware status information, etc. When passing these first parameters, a certain parameter passing method is usually adopted to encapsulate and integrate these first parameters into first parameter data of a specific data structure, and store them in the memory, so that the system kernel can use these first parameters from the memory to complete the transfer of the first parameters to the system kernel, that is, the parameter items and parameter storage structures contained in the first parameter data stored in the memory using different parameter passing methods are different. Among them, the above-mentioned parameter passing method may include but is not limited to Flattened Device Tree (Flattened Device Tree, FDT), Advanced Configuration and Power Interface (Advanced Configuration and Power Interface, ACPI), etc., and the embodiment of the present invention does not make specific limitations.

[0074] Due to the diversity of parameter transmission methods, different versions of firmware and boot booters may use different parameter transmission methods to pass parameters to the system kernel, and different boards' firmware and boot booters may also use different parameter transmission methods to pass parameters to the system kernel. In order to enable the system kernel to correctly receive the first parameter transmitted by different parameter transmission methods and improve the compatibility of the system kernel, when storing the first parameter data in the memory, the first parameter transmission method mark of the first parameter data can be stored in the first preset storage space, that is, different data structure marks correspond to different parameter transmission methods, and the first parameter data stored in the memory using different parameter transmission methods have different data structure marks. Among them, the first preset storage space may include but is not limited to a specific memory space in the memory, a specific general-purpose register, etc., and the parameter transmission method mark can be flexibly set according to actual business needs, and the embodiment of the present invention does not make specific limitations.

[0075] Step 102: Obtain the first parameter transfer mode mark from the first preset storage space, and determine the corresponding first data structure information based on the first parameter transfer mode mark.

[0076] After storing the first parameter transfer mode mark in the first preset storage space, the system kernel can read the first preset storage space, obtain the first parameter transfer mode mark therein, and determine the first data structure information capable of parsing the first parameter data according to the first parameter transfer mode mark. The first data structure information may include the corresponding relationship between the parameter type of the first parameter and the offset address of the first parameter in the first parameter data; the first data structure information may also include the corresponding relationship between the parameter type of the first parameter and the parameter identification information of the first parameter in the first parameter data, which is not specifically limited in the embodiment of the present invention.

[0077] It should be noted that the above-mentioned first parameter passing method mark can be read directly from the first preset storage space by the system kernel program, and its corresponding first data structure information can be determined; the above-mentioned first parameter passing method mark can also be read from the first preset storage space by other programs, and its corresponding first data structure information can be determined, and then the first data structure information is sent to the system kernel by other programs, thereby reducing the modification of the system kernel program and improving the stability of the system kernel. The embodiment of the present invention does not make specific limitations.

[0078] Step 103: Parse the first parameter data based on the first data structure information so that the system kernel obtains the first parameter.

[0079] During the loading process, the system kernel needs to understand the current device information, the method of loading the operating system, the configuration of the operating system and other parameters through the first parameters. In order to obtain these first parameters, the system kernel can parse the first parameter data based on the first data structure information, and obtain the first parameter therefrom, thereby supporting different parameter passing methods, and then configure the hardware device information, system behavior information, root file system, driver information, etc. of the operating system based on the first parameter, thereby ensuring that the operating system can be loaded and run normally.

[0080] In summary, in the process of parameter passing, the embodiment of the present invention stores the first parameter data to be passed to the system kernel in the memory, stores the first parameter passing mode mark of the first parameter data in the first preset storage space; obtains the first parameter passing mode mark from the first preset storage space, determines the corresponding first data structure information based on the first parameter passing mode mark; and the system kernel parses the first parameter data based on the first data structure information to obtain the first parameter. The present invention can parse the first parameter data to be passed to the system kernel in an appropriate manner according to the parameter passing mode mark to obtain the first parameter, thereby enabling the system kernel to support multiple parameter passing modes, which helps to improve the operating stability and compatibility of the system kernel.

[0081] Reference Figure 2 , Figure 2A flow chart showing another parameter transfer method embodiment provided by an embodiment of the present invention is shown, which is applied to electronic devices, such as Figure 2 As shown, the specific steps include:

[0082] Step 201, loading the firmware of the electronic device, storing the first parameter data in the memory through the firmware, and storing the first parameter transmission mode mark in the first preset storage space.

[0083] In some electronic devices, the installed firmware can directly guide the system kernel to start up and can directly pass parameters to the system kernel. These firmwares may include but are not limited to firmware developed in accordance with the Unified Extensible Firmware Interface (UEFI) specification, Coreboot firmware, etc., and the embodiments of the present invention do not make specific limitations.

[0084] Reference Figure 3 , Figure 3 A schematic diagram of a parameter transfer path provided by an embodiment of the present invention is shown. Figure 3 As shown, the firmware can directly pass the first parameter data to the system kernel.

[0085] The above-mentioned firmware may use different parameter transmission methods to pass the first parameter to the system kernel due to different versions or operating architectures, and different parameter transmission methods use different data structures to record the first parameter. In an embodiment of the present invention, corresponding parameter transmission method tags can be set for different parameter transmission methods, and a first preset storage space for recording the parameter transmission method tags can be set. By adjusting the firmware program, it can store the first parameter transmission method tag corresponding to the parameter transmission method used to transmit the first parameter in the first preset storage space when passing the first parameter to the system kernel.

[0086] Exemplarily, the parameter passing mode flag may be set to include FLAG1 and FLAG2, and the first preset storage space is the general register EAX, wherein FLAG1 corresponds to the parameter passing mode FDT, and FLAG2 corresponds to the parameter passing mode ACPI. If a firmware obtains the corresponding first parameter through the parameter passing mode ACPI after loading, and encapsulates each first parameter according to the parameter passing mode ACPI to obtain the first parameter data, the firmware may store the first parameter data in the memory, and write the FLAG2 corresponding to the parameter passing mode ACPI into the above-mentioned general register EAX.

[0087] Step 202, load the system kernel, and obtain the first parameter passing method mark from the first preset storage space through the system kernel, so that the system kernel matches the first parameter passing method mark with the preset corresponding relationship defined in the system kernel, and determines the first data structure information corresponding to the first parameter passing method mark; the preset corresponding relationship includes a one-to-one correspondence between multiple parameter passing method marks and multiple data structure information.

[0088] In the embodiment of the present invention, after the firmware writes the first parameter data in the memory, the system kernel can be loaded. After the system kernel is started, the system kernel obtains the parameter mode type tag from the first preset storage space, and matches the parameter mode type tag with the preset corresponding relationship to determine the first data structure information corresponding to the first parameter transmission mode tag. The above preset corresponding relationship may include a one-to-one correspondence between multiple parameter transmission mode tags and multiple data structure information.

[0089] In an embodiment of the present invention, the system kernel program can be rewritten so that it can read the first preset storage space after loading, obtain the first parameter passing method mark, and determine the corresponding first data structure information according to the first parameter passing method mark. The above preset corresponding relationship can be defined in the system kernel code.

[0090] The above-mentioned first data structure information may include multiple parameter types, parameter offset addresses corresponding to each parameter type and space sizes corresponding to each parameter type, wherein the parameter type is used to indicate the type of the first parameter contained in the first parameter data, and the parameter offset address is used to indicate the position of the specific parameter corresponding to the parameter type in the first parameter data.

[0091] Exemplarily, a first data structure information may be in the form of the following Table 1:

[0092] Parameter Type Parameter offset address Space size CPU Information 0x4e000000 4KB Memory information 0xff000000 2KB System boot information 0x71000000 4KB

[0093] Table 1

[0094] It should be noted that the above Table 1 is only an exemplary display. The first data structure information may include a large number of parameter types, other information besides the first parameter, and nested parameter structures. The first data structure information may also have other structures, which are not specifically limited in the embodiments of the present invention.

[0095] Step 203: Parse the first parameter data based on the first data structure information so that the system kernel obtains the first parameter.

[0096] Normally, the first data storage address of the first parameter data in the memory is passed to the system kernel through a specific storage space, and the system kernel obtains the first parameter data from the corresponding area in the memory based on the first data address. When the first parameter data is passed in different parameter passing methods, or when different kernels pass the first parameter data, the same storage space may be used to store the above-mentioned first data address, or different storage spaces may be used to store the above-mentioned first data address. Therefore, in order to enable the system kernel to correctly obtain the first parameter data in different parameter passing methods, before parsing the first parameter data, the first parameter data can be obtained in the following manner:

[0097] Optionally, the system kernel determines a first parameter pointer space based on the first parameter transfer mode mark, obtains the first parameter storage address from the first parameter pointer space, and obtains the first parameter data from the memory based on the first parameter storage address.

[0098] In an embodiment of the present invention, corresponding storage spaces may be set for different parameter transfer mode marks, so that after the system kernel obtains the first parameter transfer mode mark, it may determine the first parameter pointer space according to the first parameter transfer mode mark, and then obtain the first parameter storage address indicating the storage location of the first parameter data in the memory from the first parameter pointer space, and read the first parameter data from the memory based on the first parameter storage address. Among them, the first parameter pointer space may include but is not limited to register space, memory space, etc., the first parameter pointer space may include multiple subspaces, each subspace may include one or more first parameter storage addresses, and accordingly, multiple segments of parameter data may be obtained from multiple locations in the memory according to these first parameter storage addresses, and these multiple segments of parameter data may together constitute complete first parameter data.

[0099] Exemplarily, the kernel may divide the first parameter data into three parts and store them in three memory spaces, and store the first parameter storage address 1, the first parameter storage address 2 and the first parameter storage address 3 corresponding to the three parts of the first parameter data in the general register 1, the general register 2 and the general register 3 respectively, and write the first parameter transfer mode mark in the first preset storage space. After the system kernel is started, the first parameter transfer mode mark can be obtained from the first preset storage space, and the corresponding first parameter pointer space including the general register 1, the general register 2 and the general register 3 can be determined according to the first parameter transfer mode mark, and then the first parameter storage address 1, the first parameter storage address 2 and the first parameter storage address 3 can be obtained, and the corresponding memory space can be read based on the first parameter storage address 1, the first parameter storage address 2 and the first parameter storage address 3 to obtain the first parameter data.

[0100] By marking the first parameter passing method to determine the first parameter pointer space, obtaining the first parameter storage address from the first parameter pointer space, and obtaining the first parameter data from the memory based on the first parameter storage address, the system kernel can support multiple storage methods of the first parameter data, which helps to further improve the compatibility of the system kernel with different parameter passing methods.

[0101] After obtaining the first parameter data, the system kernel can parse the first parameter data based on the first data structure information. Specifically, the parameter type contained therein can be determined according to the first data structure information, and the parameter offset address corresponding to each parameter type can be obtained, and the first parameter can be read from the first parameter data according to the parameter offset address.

[0102] In some cases, some system kernels can only call parameters stored in a specific format, that is, they can only call parameters from parameter data generated based on a specific parameter passing method. In this case, the read first parameter can also be transferred according to the data structure required by the system kernel to reduce the extent of program modification to these system kernels. The first parameter data can be converted in the following steps A1 to A2:

[0103] Step A1, based on the parameter data record structure corresponding to the target parameter transmission method natively supported by the system kernel, encapsulate the first parameter to obtain target parameter data.

[0104] The target parameter transmission method natively supported by the system kernel refers to the parameter transmission method that the system kernel can support without making any changes to the system kernel. In an embodiment of the present invention, the system kernel program can be adjusted to enable it to parse the first parameter data transmitted by the non-natively supported parameter transmission method and obtain the first parameter, and then re-encapsulate the first parameter according to the parameter data record structure corresponding to the target parameter transmission method natively supported by the system kernel to obtain the target parameter data.

[0105] Step A2, storing the target parameter storage address of the target parameter data in the target parameter pointer space corresponding to the target parameter passing method, so that the system kernel obtains the target parameter data based on the target parameter storage address obtained from the target parameter pointer space, and calls the first parameter therein based on the target parameter data.

[0106] After obtaining the target parameter data, the target parameter data can be stored in the memory, and at the same time, the target parameter storage address of the target parameter data in the memory is stored in the target parameter pointer space corresponding to the target parameter transfer method, so that it can support multiple parameter transfer methods without changing the native operation logic of the system kernel. Among them, the target parameter pointer space represents the space where the pointer of the parameter data needs to be stored when passing the parameter data to the system kernel based on the target parameter transfer method. The target parameter pointer space may include but is not limited to memory space, register space, etc.

[0107] Exemplarily, if the firmware adopts parameter transmission mode 1 to pass to the system kernel, and the target parameter transmission mode natively supported by the system kernel is parameter transmission mode 2, then when the firmware transmits the first parameter data, the first parameter transmission mode mark can be synchronously stored in the first preset storage space. When the system kernel receives the parameter, it first reads the first parameter transmission mode mark from the first preset storage space, and then determines the corresponding first data structure information and the first parameter pointer space according to the first parameter transmission mode mark, locates the first parameter data in the memory through the first parameter storage address in the first parameter pointer space, and then parses the first parameter data according to the first data structure information to obtain the first parameter, and then adopts the parameter data record structure corresponding to parameter transmission mode 2 to re-encapsulate the first parameter to obtain the target parameter data, and stores the target parameter storage address of the target parameter data in the memory in the target parameter pointer space of parameter transmission mode 2, so that the system kernel can read the target parameter pointer space in the native operation mode to obtain the target parameter storage address, and obtain the target parameter data from the memory through the target parameter storage address. Since the system kernel natively supports parameter transmission mode 2, the first parameter can be called and operated normally based on the target parameter data.

[0108] By encapsulating the first parameter and obtaining the target parameter data based on the parameter data record structure corresponding to the target parameter passing method natively supported by the system kernel, the target parameter storage address of the target parameter data is stored in the target parameter pointer space corresponding to the target parameter passing method, so that the system kernel can call the first parameter therein based on the target parameter data. Without changing the operating logic of the system kernel, the system kernel can run based on the native parameter parsing and calling method, and at the same time support a variety of different parameter passing methods, which helps to improve the compatibility and operating stability of the system kernel.

[0109] In summary, in the process of parameter passing, the embodiment of the present invention can determine the first parameter pointer space through the first parameter passing mode mark, obtain the first parameter storage address from the first parameter pointer space, and obtain the first parameter data from the memory based on the first parameter storage address, so that the system kernel can support multiple storage methods of the first parameter data, which helps to further improve the compatibility of the system kernel with different parameter passing methods. By encapsulating the first parameter based on the parameter data record structure corresponding to the target parameter passing mode natively supported by the system kernel, the target parameter data is obtained, and the target parameter storage address of the target parameter data is stored in the target parameter pointer space corresponding to the target parameter passing mode, so that the system kernel calls the first parameter therein based on the target parameter data, and can make the system kernel run based on the native parameter parsing and calling mode without changing the operating logic of the system kernel, and support multiple different parameter passing modes at the same time, which helps to improve the compatibility and operation stability of the system kernel. According to the parameter passing mode mark, the first parameter data to be passed to the system kernel can be parsed in an appropriate manner to obtain the first parameter, so that the system kernel can support multiple parameter passing modes, which helps to improve the operation stability and compatibility of the system kernel.

[0110] Reference Figure 4 , Figure 4 A flowchart showing another parameter transfer method embodiment provided by an embodiment of the present invention is shown, which is applied to electronic devices such as Figure 4 As shown, the specific steps include:

[0111] Step 301, loading the firmware and boot boot of the electronic device, passing the second parameter to the boot boot through the firmware, so that the boot boot stores the first parameter data in the memory based on the second parameter and stores the first parameter transfer mode mark in the first preset storage space.

[0112] In some electronic devices, the firmware cannot directly guide the system kernel to start the operating system, and it is necessary to indirectly pass parameters to the system kernel through the boot booter. Therefore, the firmware and the boot booter of the electronic device can be loaded, and the firmware first passes the second parameter to the boot booter, and then the boot booter encapsulates the second parameter based on its own parameter passing method to obtain the first parameter data, stores the first parameter data in the memory to pass the first parameter to the system kernel, and stores the first parameter passing method mark in the first preset storage space.

[0113] Reference Figure 5 , Figure 5 FIG. 4 shows another schematic diagram of a parameter transfer path provided by an embodiment of the present invention. Figure 5As shown, the second parameter can be passed from the firmware to the boot loader, and the boot loader obtains the first parameter data based on the second parameter encapsulation, and the boot loader passes the first parameter data to the system kernel.

[0114] The above-mentioned boot loader may adopt different parameter transmission methods to pass the first parameter to the system kernel due to different versions or operating architectures, and different parameter transmission methods use different data structures to record the first parameter. In an embodiment of the present invention, corresponding parameter transmission method marks can be set for different parameter transmission methods, and a first preset storage space for recording the parameter transmission method marks can be set. By adjusting the boot loader program, it can store the first parameter transmission method mark corresponding to the parameter transmission method adopted for transmitting the first parameter in the first preset storage space when transmitting the first parameter to the system kernel.

[0115] Exemplarily, the parameter passing mode flag may be set to include FLAG1 and FLAG2, and the first preset storage space is the general register EAX, wherein FLAG1 corresponds to the parameter passing mode FDT, and FLAG2 corresponds to the parameter passing mode ACPI. If a boot loader obtains the corresponding first parameter through the parameter passing mode ACPI after loading, and encapsulates each first parameter according to the parameter passing mode ACPI to obtain the first parameter data, the boot loader may store the first parameter data in the memory, and write the FLAG2 corresponding to the parameter passing mode ACPI into the above-mentioned general register EAX.

[0116] By enabling the boot loader to store the first parameter data in the memory based on the second parameter and to store the first parameter passing method mark in the first preset storage space, the parameter passing method of the first parameter data passed in by the boot loader can be determined based on the first parameter mark, so that the first parameter data can be received and the first parameter therein can be parsed in a suitable manner, which helps to improve the compatibility of the system kernel with boot loader devices with different parameter passing methods.

[0117] Optionally, step 301 may include:

[0118] Sub-step 3011, storing the second parameter data in the memory through the firmware.

[0119] Due to different versions or operating architectures, the firmware may use different parameter transmission methods to pass the second parameter to the boot loader, and different parameter transmission methods use different data structures to record the second parameter. In an embodiment of the present invention, when passing the second parameter to the boot loader, the firmware can generate corresponding second parameter data based on the second parameter to be passed, and store the second parameter data in the memory.

[0120] Sub-step 3012, obtaining storage data in at least one second preset storage space of the memory.

[0121] Since usually, when a second parameter is passed using a certain parameter passing method, specific data will be written in a specific storage space in the memory, the storage data in the specific storage space can be read as verification data to determine the parameter passing method used by the firmware.

[0122] Exemplarily, the second preset storage space may include space 1, space 2 and space 3. If the firmware adopts parameter passing method A to pass the second parameter to the boot loader, 04 will be written in space 2 and 05 will be written in space 3, and no data will be written in space 1. Therefore, the data in space 1 can be a null value (null). In this case, reading space 1, space 2 and space 3 can obtain storage data null, 04 and 05 respectively; if the firmware adopts parameter passing method B to pass the second parameter to the boot loader, 02 will be written in space 1 and 05 will be written in space 3, and no data will be written in space 2. Therefore, the data in space 2 can be a null value (null). In this case, reading space 1, space 2 and space 3 can obtain storage data 01, null and 05 respectively.

[0123] Sub-step 3013, matching the stored data with the standard data corresponding to the second preset storage space to obtain a matching result.

[0124] In an embodiment of the present invention, at least one standard data can be set for each second preset storage space, and one standard data of a second preset storage space corresponds to a parameter transfer method, that is, the standard data refers to the data that will be stored in the second preset storage space when the second parameter is transferred using a specific parameter transfer method.

[0125] Exemplarily, the second preset storage space may include space 1, space 2 and space 3, wherein the standard data corresponding to space 1 may include 01 and 11, the standard data corresponding to space 2 may include 09 and 22, and the standard data corresponding to space 3 may include 05.

[0126] In the embodiment of the present invention, the storage data of each second preset storage space can be matched with the standard data corresponding to the second preset storage space to obtain a matching result. The matching result may include the second preset storage space that can be matched successfully, for example, the matching result may be: successfully matched with space 1 and space 3; in addition, the matching result may also include the second preset storage space that can be matched successfully and the standard data that can be matched successfully, for example, the matching result may be: successfully matched with 01 in space 1 and 09 in space 2. The embodiment of the present invention does not specifically limit the format and form of the above matching results.

[0127] Sub-step 3014, determining corresponding second data structure information based on the matching result, so that the boot loader parses the second parameter data based on the second data structure information, so that the boot loader obtains the second parameter.

[0128] In an embodiment of the present invention, corresponding data structure information can be set for different matching results, so that after obtaining the matching result, the corresponding second data structure information is determined according to the matching result, so that the boot loader can parse the second parameter data passed by the kernel based on the second data structure information to obtain the second parameter, so that the boot loader can support firmware with different parameter transmission methods, which helps to improve the compatibility of the boot loader.

[0129] Reference Figure 6 , Figure 6 A schematic diagram of boot loader compatibility provided by an embodiment of the present invention is shown. Figure 6 As shown, the boot loader is compatible with firmware 1, firmware 2 and firmware 3 that use different parameter transmission methods. After determining the second data structure information corresponding to the firmware, the second parameter data can be parsed to obtain the second parameter, and then the second parameter is encapsulated to obtain the first parameter data, and the first parameter data is transmitted to the system kernel.

[0130] Optionally, corresponding parameter transmission mode marks may be set for different parameter transmission modes, and a second preset storage space for recording the parameter transmission mode marks may be set. By adjusting the firmware program, when the second parameter is transmitted to the boot loader, the second parameter transmission mode mark corresponding to the parameter transmission mode adopted for transmitting the second parameter is stored in the second preset storage space.

[0131] Step 302, load the system kernel, and obtain the first parameter passing method mark from the first preset storage space through the system kernel, so that the system kernel matches the first parameter passing method mark with the preset corresponding relationship defined in the system kernel, and determines the first data structure information corresponding to the first parameter passing method mark; the preset corresponding relationship includes a one-to-one correspondence between multiple parameter passing method marks and multiple data structure information.

[0132] This step can be referred to as step 202, and will not be described in detail in this embodiment of the present invention.

[0133] Step 303: Parse the first parameter data based on the first data structure information so that the system kernel obtains the first parameter.

[0134] This step can be referred to as step 203, and will not be described in detail in this embodiment of the present invention.

[0135] In summary, in the process of parameter transmission, the embodiment of the present invention can determine the corresponding second data structure information according to the matching result, so that the boot loader can parse the second parameter data transmitted by the kernel based on the second data structure information to obtain the second parameter, so that the boot loader can support firmware with different parameter transmission methods, which helps to improve the compatibility of the boot loader. According to the parameter transmission method mark, the first parameter data that needs to be transmitted to the system kernel can be parsed in an appropriate manner to obtain the first parameter, so that the system kernel can support multiple parameter transmission methods, which helps to improve the operating stability and compatibility of the system kernel.
