[0053] 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 only 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.

[0054] See also Figure 1 , Figure 1 A flowchart of a bandwidth configuration method provided in an embodiment of the present application.

[0055] A bandwidth configuration method provided in an embodiment of the present application, applied to system firmware, may include the following steps:

[0056] Step S101: Determine the total bandwidth of the target slot.

[0057] Step S102: Generate all initial bandwidth configuration modes of the target slot according to the total bandwidth.

[0058] In actual applications, the bandwidth allocated to each slot has an upper limit, that is, the total bandwidth of the slot is fixed, and the bandwidth allocated to the slot by the system firmware must be equal to the total bandwidth. Therefore, the system firmware needs to determine the total bandwidth of the target slot and generate all initial bandwidth configuration methods for the target slot based on the total bandwidth. Each initial bandwidth configuration method makes the bandwidth of the target slot equal to the total bandwidth.

[0059] Step S103: bandwidth is configured for the target slot according to the initial bandwidth configuration mode, and device identification is performed on the target slot to obtain an initial device quantity value of the target slot under each initial bandwidth configuration mode.

[0060] In actual applications, after obtaining all initial bandwidth configuration modes of the target slot, the system firmware can configure the bandwidth of the target slot according to each initial bandwidth configuration mode. Since the target slot can be identified after the bandwidth is configured, the target slot can be identified next to obtain the initial device quantity value of the target slot under each initial bandwidth configuration mode, so as to subsequently apply the initial device quantity value of the target slot under each initial bandwidth configuration mode to determine the final bandwidth configuration mode of the target slot.

[0061] Step S104: Determine the maximum initial device quantity value as the target device quantity value.

[0062] Step S105: Determine a target bandwidth configuration mode according to the initial bandwidth configuration mode corresponding to the target device quantity value.

[0063] Step S106: performing bandwidth configuration on the target slot according to the target bandwidth configuration method.

[0064] In practical applications, it is considered that the bandwidth configuration mode of the target slot will affect the number of devices identified. For example, if the total bandwidth of the target slot is x16 and the initial bandwidth configuration mode is x8x8, assuming that the target devices are two x8 devices, then the initial device quantity value under this configuration mode is 2. Assuming that the initial bandwidth configuration mode is x16, only one device can be detected, that is, the initial device quantity value under this configuration mode is 1. By comparison, it can be seen that the initial bandwidth configuration mode corresponding to the largest initial device quantity value matches the target bandwidth configuration mode, so the largest initial device quantity value can be determined as the target device quantity value. According to the initial bandwidth configuration mode corresponding to the target device quantity value, the target bandwidth configuration mode is determined, and finally the bandwidth of the target slot is configured according to the target bandwidth configuration mode.

[0065] In a specific application scenario, in the process of generating all initial bandwidth configuration modes of a target slot according to the total bandwidth, considering that the total bandwidth only limits the total bandwidth of the target slot, and the bandwidth of the target slot is composed of multiple setting values, the optional bandwidth setting value of the target slot can be determined; the optional bandwidth setting values ​​are combined to obtain each initial bandwidth configuration mode whose bandwidth value is equal to the total bandwidth.

[0066] In a specific application scenario, in the process of combining the optional bandwidth setting values ​​to obtain each initial bandwidth configuration mode in which the bandwidth value is equal to the total bandwidth, the optional bandwidth setting values ​​can be randomly combined to obtain each initial bandwidth configuration mode in which the bandwidth value is equal to the total bandwidth, or each initial bandwidth configuration mode can be obtained by combining and calculating the optional bandwidth setting values. For example, each optional bandwidth setting value can be used as a reference bandwidth setting value, and an unselected reference bandwidth setting value can be selected as the selected bandwidth setting value; the difference between the total bandwidth and the selected bandwidth setting value is generated, and an optional bandwidth setting value that is not greater than the difference is used as a candidate bandwidth setting value, and an unselected candidate bandwidth setting value is selected as the selected bandwidth setting value, and it is detected whether the selected bandwidth setting value is equal to the total bandwidth. If the selected bandwidth setting value is less than the total bandwidth, the selection is returned and the execution is performed. a step of selecting a candidate bandwidth setting value that has not been selected as the selected bandwidth setting value; if the selected bandwidth setting value is equal to the total bandwidth, using the selected bandwidth setting value as an initial bandwidth configuration mode, detecting whether there is a candidate bandwidth setting value that has not been combined with the benchmark bandwidth setting value; if there is a candidate bandwidth setting value that has not been combined with the benchmark bandwidth setting value, returning to execute the step of generating the difference between the total bandwidth and the selected bandwidth setting value to generate a new initial bandwidth configuration mode based on the benchmark bandwidth setting value; if all candidate bandwidth setting values ​​have been combined with the benchmark bandwidth setting value, returning to execute the step of selecting a benchmark bandwidth setting value that has not been selected as the selected bandwidth setting value to generate a new initial bandwidth configuration mode based on the new benchmark bandwidth setting value, until all benchmark bandwidth setting values ​​have participated in the selection, and all initial bandwidth configuration modes are obtained.

[0067] It can be seen from the implementation process that in the present application, in the process of combining the optional bandwidth setting values ​​to obtain each initial bandwidth configuration mode in which the bandwidth value is equal to the total bandwidth, each optional bandwidth setting value is first used as the reference bandwidth setting value, and the initial bandwidth configuration mode based on various optional bandwidth setting values ​​can be obtained by selecting the reference bandwidth setting value, and after selecting a reference bandwidth setting value that has not been selected as the selected bandwidth setting value, the candidate bandwidth setting value can be determined according to the difference between the total bandwidth and the selected bandwidth setting value, and various initial bandwidth configuration modes under the reference bandwidth setting value are obtained by combining the candidate bandwidth setting value and the current reference bandwidth setting value. In addition, other initial bandwidth configuration modes can be obtained by simply updating the reference bandwidth setting value, so that all initial bandwidth configuration modes can be exhaustively enumerated by updating and combining the reference bandwidth setting value and the corresponding candidate bandwidth setting value, and there is no situation where the initial bandwidth configuration mode is omitted, thereby ensuring the exhaustive accuracy of the initial bandwidth configuration mode.

[0068] In a specific application scenario, when the system firmware generates all initial bandwidth configuration modes of the target slot according to the total bandwidth, the system firmware can generate all initial bandwidth configuration modes of the target slot according to the total bandwidth during the initialization (PEI) phase, that is, the method of the present application can be applied to the initialization phase of the system firmware. In addition, the type of system firmware can be flexibly determined according to actual needs, for example, the system firmware can be a basic input output system (BIOS), etc.

[0069] In a specific application scenario, in the process of determining the target bandwidth configuration mode according to the initial bandwidth configuration mode corresponding to the target device quantity value, the system firmware can further determine the target bandwidth configuration mode according to the rated bandwidth of the target device, that is, each initial bandwidth configuration mode corresponding to the target device quantity value can be used as a candidate bandwidth configuration mode; count the number of candidate bandwidth configuration modes; detect whether the number of candidate bandwidth configuration modes is one; in response to the number of candidate bandwidth configuration modes being one, determine the candidate bandwidth configuration mode as the target bandwidth configuration mode; in response to the number of candidate bandwidth configuration modes being greater than one, read the rated bandwidth of each target device; determine the candidate bandwidth configuration mode whose maximum bandwidth value is not greater than the rated bandwidth and is the largest as the target bandwidth configuration mode, that is, determine the candidate bandwidth configuration mode whose bandwidth value is not greater than the rated bandwidth and has the largest bandwidth value as the target bandwidth configuration mode. For ease of understanding, assuming that the total bandwidth of the target slot is x16, there are three initial bandwidth configuration modes, namely x16, x8x8 and x4x4x4. Assuming that there are two target devices with a rated bandwidth of x8, the initial device quantity values ​​corresponding to the three initial bandwidth configuration modes of x16, x8x8 and x4x4x4 are 1, 2 and 0 respectively. At this time, the candidate bandwidth configuration mode is only x8x8, so the target bandwidth configuration mode can be determined to be x8x8. Assuming that there is a target device with a rated bandwidth of x16, the initial device quantity values ​​corresponding to the three initial bandwidth configuration modes of x16, x8x8 and x4x4x4 are 1, 1 and 0 respectively. At this time, the candidate bandwidth configuration modes are x16 and x8x8, so the target bandwidth configuration mode needs to be determined as x16 according to the rated bandwidth of the target device.

[0070] In a specific application scenario, the system firmware configures the bandwidth of the target slot according to the initial bandwidth configuration mode, identifies the device of the target slot, and obtains the initial device quantity value of the target slot under each initial bandwidth configuration mode. In the process, an initial bandwidth configuration mode not recorded in the non-volatile memory can be selected as the bandwidth configuration mode to be tested; the bandwidth of the target slot is configured according to the bandwidth configuration mode to be tested, and the device of the target slot is identified to obtain the initial device quantity value of the target slot under the bandwidth configuration mode to be tested. For example, a depth-first strategy can be used to traverse the device. If the device can be identified normally, the BDF (Bu s / Device / Function) and the parent slot ID, obtain the design generation table of each slot and store the table in the non-volatile memory; store the bandwidth configuration mode to be tested and the corresponding initial device quantity value in the non-volatile memory; detect whether all kinds of initial bandwidth configuration modes are stored in the non-volatile memory; in response to not storing all kinds of initial bandwidth configuration modes in the non-volatile memory, control the server to select an initial bandwidth configuration mode not recorded in the non-volatile memory as the bandwidth configuration mode to be tested after restarting; in response to all kinds of initial bandwidth configuration modes being stored in the non-volatile memory, end.

[0071] From this implementation process, it can be known that the present application uses a non-volatile memory to record the initial device quantity value of the target slot under each initial bandwidth configuration mode. In this way, after the bandwidth of the target slot is configured according to a bandwidth configuration mode to be tested, and the device of the target slot is identified, and the initial device quantity value of the target slot under the bandwidth configuration mode to be tested is obtained, the bandwidth configuration mode to be tested and the corresponding initial device quantity value can be stored in the non-volatile memory. In this way, if there are still bandwidth configuration modes to be tested that have not been recorded in the non-volatile memory, it indicates that the recording of the initial device quantity values ​​corresponding to all initial bandwidth configuration modes has not been completed, and it is necessary to continue to count the initial device quantity values ​​corresponding to the bandwidth configuration mode to be tested, thereby achieving the effect of systematically counting the initial device quantity values ​​corresponding to the initial bandwidth configuration mode with the help of a non-volatile memory, avoiding the situation of missing the initial device quantity value corresponding to the initial bandwidth configuration mode, and ensuring the statistical accuracy of the initial device quantity value.

[0072] In a specific application scenario, after the system firmware configures the bandwidth of the target slot according to the target bandwidth configuration method, it can also generate a correspondence between the target slot and the target bandwidth configuration method; store the correspondence in a non-volatile memory so that the corresponding relationship stored in the non-volatile memory can be directly applied next time to configure the bandwidth of the target slot.

[0073] The present application provides a bandwidth configuration method, which is applied to system firmware to determine the total bandwidth of a target slot; generate all initial bandwidth configuration modes of the target slot according to the total bandwidth; configure the bandwidth of the target slot according to the initial bandwidth configuration mode, and identify the device of the target slot to obtain the initial device quantity value of the target slot under each initial bandwidth configuration mode; determine that the initial device quantity value with the largest value is the target device quantity value; determine the target bandwidth configuration mode according to the initial bandwidth configuration mode corresponding to the target device quantity value; and configure the bandwidth of the target slot according to the target bandwidth configuration mode. The system firmware in the present application only needs to know the total bandwidth of the target slot, and then it can generate all the initial bandwidth configuration methods of the target slot according to the total bandwidth, that is, exhaustively enumerate all the initial bandwidth configuration methods of the target slot, and then consider that if the initial bandwidth configuration method is compatible with the device on the target slot, all the devices on the target slot will be identified, that is, the maximum number of devices will be obtained, so the initial device quantity value of the target slot under each initial bandwidth configuration method can be determined, and the final target bandwidth configuration method of the target slot can be determined according to the initial bandwidth configuration method corresponding to the initial device quantity value with the largest value, thereby realizing the screening of the target bandwidth configuration method by exhaustively enumerating all bandwidth configuration methods and according to the number of identified devices, getting rid of the supplier's restrictions on bandwidth allocation, and having high flexibility.

[0074] To facilitate understanding of the bandwidth configuration scheme of the present application, it is now assumed that the system firmware is a basic input and output system. In the process of configuring the bandwidth of the target slot, the baseboard input and output system can perform the following steps:

[0075] After entering the initialization phase, check whether the bandwidth configuration switch of the target slot is turned on through the user interface;

[0076] If enabled, the total bandwidth of the target slot is determined;

[0077] Generate all initial bandwidth configuration modes for the target slot based on the total bandwidth;

[0078] The value of the initialization flag is 1;

[0079] Select an initial bandwidth configuration mode that has not been selected to configure the bandwidth of the target slot, identify the device of the target slot, obtain the initial device quantity value of the target slot under this initial bandwidth configuration mode, and increase the value of the flag bit by 1;

[0080] Check whether the flag value is greater than the total number of initial bandwidth configuration modes;

[0081] If the value of the flag bit is less than or equal to the total number of initial bandwidth configuration methods, return to the step of selecting an initial bandwidth configuration method that has not been selected to configure the bandwidth of the target slot;

[0082] If the value of the flag bit is greater than the total number of initial bandwidth configuration methods, the initial device quantity value with the largest value is determined as the target device quantity value;

[0083] Each initial bandwidth configuration method corresponding to the target device quantity value is used as a candidate bandwidth configuration method;

[0084] Count the number of candidate bandwidth configuration methods;

[0085] Detecting whether the number of candidate bandwidth configuration modes is one;

[0086] In response to the number of candidate bandwidth configuration modes being one, determining the candidate bandwidth configuration mode as the target bandwidth configuration mode;

[0087] In response to the number of candidate bandwidth configuration modes being greater than one, reading the rated bandwidth of each target device; determining the largest candidate bandwidth configuration mode having a maximum bandwidth value not greater than the rated bandwidth as the target bandwidth configuration mode;

[0088] Write the target bandwidth configuration mode into the non-volatile memory and set a restart;

[0089] After restarting, the target bandwidth configuration mode in the non-volatile memory is read, and the bandwidth of the target slot is configured according to the target bandwidth configuration mode.
