[0053] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0054] Please refer to Figure 1 , Figure 1 A flowchart of a bandwidth configuration method provided by an embodiment of the present application.

[0055] The bandwidth configuration method provided by an embodiment of the present application is applied to a system firmware and can 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 application, 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 needs to be equal to the total bandwidth, so the system firmware needs to determine the total bandwidth of the target slot and generate all initial bandwidth configuration modes of the target slot according to the total bandwidth, and each initial bandwidth configuration mode makes the bandwidth of the target slot equal to the total bandwidth.

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

[0060] In actual application, after the system firmware obtains all initial bandwidth configuration modes of the target slot, the system firmware can perform bandwidth configuration on the target slot according to each initial bandwidth configuration mode. Since the target slot can be identified after the bandwidth configuration, the target slot can be identified next to obtain an initial device quantity value of the target slot under each initial bandwidth configuration mode, so as to determine the final bandwidth configuration mode of the target slot by using the initial device quantity value of the target slot under each initial bandwidth configuration mode subsequently.

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

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

[0063] Step S106: configuring the target slot according to the target bandwidth configuration mode.

[0064] In practical application, considering that the bandwidth configuration mode of the target slot will affect the recognized device quantity, for example, the total bandwidth of the target slot is x16, the initial bandwidth configuration mode is x8x8, assuming that the target device is 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, the initial bandwidth configuration mode corresponding to the initial device quantity value with the maximum value matches the target bandwidth configuration mode, so it can be determined that the initial device quantity value with the maximum value is the target device quantity value, the target bandwidth configuration mode is determined according to the initial bandwidth configuration mode corresponding to the target device quantity value, and finally 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 the 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 selectable bandwidth setting values of the target slot can be determined; each initial bandwidth configuration mode with a bandwidth value equal to the total bandwidth is obtained by combining the selectable bandwidth setting values.

[0066] In a specific application scenario, in the process of combining the optional bandwidth setting values to obtain each initial bandwidth configuration mode with a bandwidth value equal to the total bandwidth, the optional bandwidth setting values can be combined randomly to obtain each initial bandwidth configuration mode with a bandwidth value equal to the total bandwidth, or each initial bandwidth configuration mode can be obtained by combining the optional bandwidth setting values. For example, each optional bandwidth value setting value can be taken as a reference bandwidth setting value, and an unselected reference bandwidth setting value can be selected as a selected bandwidth setting value. The difference between the total bandwidth and the selected bandwidth setting value is generated, and the optional bandwidth setting value that is not greater than the difference is taken as a candidate bandwidth setting value. An unselected candidate bandwidth setting value is selected as a selected bandwidth setting value. 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 step of selecting an unselected candidate bandwidth setting value as a selected bandwidth setting value is returned. If the selected bandwidth setting value is equal to the total bandwidth, the selected bandwidth setting value is taken as an initial bandwidth configuration mode. It is detected whether there is a candidate bandwidth setting value that has not been combined with the reference bandwidth setting value. If there is a candidate bandwidth setting value that has not been combined with the reference bandwidth setting value, the step of generating the difference between the total bandwidth and the selected bandwidth setting value is returned to generate a new initial bandwidth configuration mode based on the reference bandwidth setting value. If all candidate bandwidth setting values have been combined with the reference bandwidth setting value, the step of selecting an unselected reference bandwidth setting value as a selected bandwidth setting value is returned to generate a new initial bandwidth configuration mode based on a new reference bandwidth setting value. Until all reference bandwidth setting values are selected, all initial bandwidth configuration modes are obtained.

[0067] According to the implementation process, in the process of combining the optional bandwidth setting values to obtain each initial bandwidth configuration mode with a bandwidth value equal to the total bandwidth, each optional bandwidth value setting value is taken as a reference bandwidth setting value. By selecting the reference bandwidth setting value, the initial bandwidth configuration mode based on the optional bandwidth setting value can be obtained. After an unselected reference bandwidth setting value is selected as a 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. The candidate bandwidth setting value and the current reference bandwidth setting value are combined to obtain various initial bandwidth configuration modes under the reference bandwidth setting value. In addition, other initial bandwidth configuration modes can be obtained by updating the reference bandwidth setting value. The initial bandwidth configuration modes can be enumerated by updating and combining the reference bandwidth setting value and the corresponding candidate bandwidth setting value. There is no missing initial bandwidth configuration mode, which ensures the enumeration accuracy of the initial bandwidth configuration mode.

[0068] In a specific application scenario, in the process of generating 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 in the initialization (PEI) stage, that is, the method can be applied to the initialization stage of the system firmware. In addition, the type of the system firmware can be flexibly determined according to actual needs, such as the system firmware can be a basic input output system (BIOS) and the like.

[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 regarded as a candidate bandwidth configuration mode; the number of candidate bandwidth configuration modes is counted; it is detected whether the number of candidate bandwidth configuration modes is one; in response to the number of candidate bandwidth configuration modes being one, the candidate bandwidth configuration mode is determined as the target bandwidth configuration mode; in response to the number of candidate bandwidth configuration modes being greater than one, the rated bandwidth of each target device is read; the candidate bandwidth configuration mode with the maximum bandwidth value not greater than the rated bandwidth and the maximum is determined as the target bandwidth configuration mode, that is, the candidate bandwidth configuration mode with the bandwidth value not greater than the rated bandwidth and the maximum bandwidth value is determined as the target bandwidth configuration mode. In order to facilitate understanding, it is assumed that the total bandwidth of the target slot is x16, there are three initial bandwidth configuration modes in total, which are x16, x8x8 and x4x4x4, and there are two target devices with a rated bandwidth of x8, then the initial device quantity values corresponding to the three initial bandwidth configuration modes x16, x8x8 and x4x4x4 are 1, 2 and 0 respectively, at this time the selected bandwidth configuration mode is only x8x8, so the target bandwidth configuration mode can be determined as x8x8, and then it is assumed that there is one target device with a rated bandwidth of x16, then the initial device quantity values corresponding to the three initial bandwidth configuration modes x16, x8x8 and x4x4x4 are 1, 1 and 0 respectively, at this time the selected bandwidth configuration mode is 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, in the process that the system firmware configures the target slot with the initial bandwidth configuration mode and identifies the device of the target slot to obtain the initial device quantity value of the target slot under each initial bandwidth configuration mode, an initial bandwidth configuration mode not recorded in the non-volatile memory can be selected as the to-be-tested bandwidth configuration mode; the target slot is configured with the to-be-tested bandwidth configuration mode, and the device of the target slot is identified to obtain the initial device quantity value of the target slot under the to-be-tested bandwidth configuration mode, for example, a depth-first strategy can be used to traverse the device, if the device can be normally identified, the BDF (Bus / Device / Function) and the upper slot ID of the connected device on each port are recorded, the design generation table of each slot is obtained and stored in the non-volatile memory; the to-be-tested bandwidth configuration mode and the corresponding initial device quantity value are stored in the non-volatile memory; it is detected whether all kinds of initial bandwidth configuration modes are stored in the non-volatile memory; in response to that not all kinds of initial bandwidth configuration modes are stored in the non-volatile memory, the server is controlled to restart to perform the step of selecting an initial bandwidth configuration mode not recorded in the non-volatile memory as the to-be-tested bandwidth configuration mode; in response to that all kinds of initial bandwidth configuration modes are stored in the non-volatile memory, the process is ended.

[0071] From the implementation process, it can be known that the initial device quantity value of the target slot under each initial bandwidth configuration mode is recorded in the non-volatile memory, so that after the target slot is configured with a to-be-tested bandwidth configuration mode and the device of the target slot is identified to obtain the initial device quantity value of the target slot under the to-be-tested bandwidth configuration mode, the to-be-tested bandwidth configuration mode and the corresponding initial device quantity value can be stored in the non-volatile memory, so if there is a to-be-tested bandwidth configuration mode not recorded in the non-volatile memory, it indicates that the recording of the initial device quantity value corresponding to all initial bandwidth configuration modes is not completed, and the initial device quantity value corresponding to the to-be-tested bandwidth configuration mode still needs to be counted, thereby achieving the effect that the initial device quantity value corresponding to the initial bandwidth configuration mode is counted in the non-volatile memory, avoiding the situation that the initial device quantity value corresponding to the initial bandwidth configuration mode is missed, and ensuring the accuracy of the initial device quantity value.

[0072] In a specific application scenario, after the system firmware configures the target slot with the target bandwidth configuration mode, a corresponding relationship between the target slot and the target bandwidth configuration mode can be generated; the corresponding relationship is stored in the non-volatile memory, so that the corresponding relationship stored in the non-volatile memory can be directly applied to configure the bandwidth of the target slot next time.

[0073] The bandwidth configuration method provided in the application is applied to system firmware, determines the total bandwidth of a target slot, generates all initial bandwidth configuration modes of the target slot according to the total bandwidth, performs bandwidth configuration on the target slot according to the initial bandwidth configuration modes, and performs device identification on the target slot to obtain initial device quantity values of the target slot under each initial bandwidth configuration mode, determines the initial device quantity value with the maximum value as a target device quantity value, determines a target bandwidth configuration mode according to the initial bandwidth configuration mode corresponding to the target device quantity value, and performs bandwidth configuration on the target slot according to the target bandwidth configuration mode. The system firmware in the application only needs to know the total bandwidth of the target slot, and can generate all initial bandwidth configuration modes of the target slot according to the total bandwidth, that is, all initial bandwidth configuration modes of the target slot are exhausted, and then if the initial bandwidth configuration mode is adapted to the device on the target slot, all devices on the target slot are identified, that is, the maximum device quantity is obtained, so that the initial device quantity values of the target slot under each initial bandwidth configuration mode can be determined, and the target bandwidth configuration mode of the target slot can be determined according to the initial bandwidth configuration mode corresponding to the initial device quantity value with the maximum value, which realizes the selection of the target bandwidth configuration mode by exhausting all bandwidth configuration modes and according to the identified device quantity, and breaks the restriction of the supplier on bandwidth allocation, and has high flexibility.

[0074] In order to facilitate understanding of the bandwidth configuration scheme of the application, it is assumed that the system firmware is a basic input and output system, and the following steps can be performed by the basic input and output system in the process of performing bandwidth configuration on the target slot:

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

[0076] If the bandwidth configuration switch is turned on, the total bandwidth of the target slot is determined;

[0077] All initial bandwidth configuration modes of the target slot are generated according to the total bandwidth;

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

[0079] An initial bandwidth configuration mode that has not been selected is selected to perform bandwidth configuration on the target slot, and device identification is performed on the target slot to obtain an initial device quantity value of the target slot under the initial bandwidth configuration mode, and the value of the flag bit is increased by 1;

[0080] Whether the value of the flag bit is greater than the total number of initial bandwidth configuration modes is detected;

[0081] If the value of the flag bit is less than or equal to the total number of initial bandwidth configuration modes, the step of selecting an initial bandwidth configuration mode that has not been selected to perform bandwidth configuration on the target slot is returned;

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

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

[0084] The number of candidate bandwidth configuration modes is counted;

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

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

[0087] In response to the number of candidate bandwidth configuration modes being greater than one, the rated bandwidth of each target device is read; the candidate bandwidth configuration mode with the maximum bandwidth value not greater than the rated bandwidth and the maximum value is determined as the target bandwidth configuration mode;

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

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