[0017] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0018] It should be noted that in the description of the present application, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. The terms "first", "second", etc. in the present application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0019] For hardware components such as graphics cards, solid-state drives, and network cards, in order to achieve efficient data transmission, they are usually connected to the computer motherboard using PCIe (Peripheral Component Interconnect Express) slots. As a new generation of high-speed serial computer expansion bus standard, PCIe provides data bandwidth far exceeding that of traditional interfaces for various hardware components through point-to-point serial connection methods.

[0020] For some hardware components with multiple physical interfaces, multiple PCIe slots need to be occupied simultaneously during use, and controllers need to be configured for each slot separately. Some hardware components support hot plugging operations in a non-stop state. However, during the hot plugging process, exceptions may occur. After an exception occurs, there is a lack of an active repair method, and it is easy to cause data processing errors.

[0021] To address the above technical problems, the inventor proposed the following technical concept: After making the slot invalid and then enabling it, and performing power-on and power-off operations on the hardware components connected to the slot to restore the connection to normal, and terminating the data transmission between the controller associated with the hardware component and the hardware component before performing the recovery process.

[0022] Figure 1 This is a schematic diagram of the scenario for restoring the connection of the hardware components provided in this application. As Figure 1 shown, the specific application scenarios of this application include:

[0023] Processor 101, Controller 102, Connection Control Register 103, CPIe Slot 104, Hardware Component 105.

[0024] Processor 101 may include: CPU (central processing unit, central processor), programmable logic device (PLD, programmable logic device) and control board, ECU (Electronic Control Unit, electronic control unit), etc.

[0025] Controller 102 may include a switch controller, an endpoint controller, a bridge controller, a root port controller, etc.

[0026] Connection Control Register 103 may include any type of register.

[0027] CPIe Slot 104 may include slots applicable to the high-speed serial computer expansion bus standard.

[0028] Hardware Component 105 may include hardware such as hard disks, graphics cards, network cards, etc.

[0029] Processor 101 is communicatively connected to Controller 102, Connection Control Register 103 and Controller 102 are communicatively connected to CEIe Slot 104, and Hardware Component 105 is pluggably installed on CEIe Slot 104.

[0030] The processor 101 is used to obtain the connection status of the hardware component 105 after it is installed in the CPIe slot 104. In the case of an abnormal connection, by changing the bit of the connection control register 103, the slot is disabled and then enabled, so that the state machine of the root port returns to the default exploration state, and the normal connection between the hardware component 105 and the CPIe slot 104 is restored. If the connection is still abnormal, the hardware component 105 is powered off and then powered on, and the connection is detected again to check if it is abnormal. If it is still abnormal, the process of disabling and then enabling the slot and the power-on and power-off processes are repeated until the connection is restored to normal or remains abnormal after repeating the preset number of times.

[0031] The following uses specific embodiments to elaborate in detail on the technical solutions of this application and how the technical solutions of this application solve the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0032] Figure 2 It is a schematic flowchart of the hardware component connection recovery method provided by this application. As Figure 2 shown, the method includes:

[0033] S201: If it is detected that a hardware component is inserted into the target slot, detect whether the connection of the hardware component is abnormal.

[0034] In this step, detecting that a hardware component is inserted into the target slot may include obtaining the presence information of the hardware component from the PCIe bus in-band. If there is presence information, it is determined that a hardware component is inserted into the target slot. It may also include detecting the high level or low level of a certain pin to determine that a hardware component is inserted into the target slot. Detecting whether the connection of the hardware component is abnormal may include: detecting whether the connection with the hardware component is disconnected, whether the bandwidth or transmission rate has decreased. If the connection is disconnected, the bandwidth has decreased, or the transmission rate has decreased, it is determined that the connection of the hardware component is abnormal.

[0035] S202: If the connection of the hardware component is abnormal, determine the target controller associated with the hardware component.

[0036] In this step, it may include looking up the correspondence between the hardware component identifier and the controller to obtain the target controller associated with the hardware component; it may also include sending hardware identifier query information to each controller to obtain the hardware identifier returned by the controller. If the hardware identifier returned by any controller is the same as the identifier of the hardware component, this controller is determined as the target controller.

[0037] S203: Send a stop transmission instruction to the target controller so that the target controller stops data transmission with the hardware component according to the stop transmission instruction.

[0038] In this step, the stop transmission instruction can be pre-set, and the target controller stops data transmission after receiving the stop transmission instruction.

[0039] S204: Set the connection failure bit of the connection control register of the target slot to a first preset value to disable the target slot and start timing to obtain a first timing duration.

[0040] In this step, the connection failure bit can be the fourth bit of the connection control register, and the first preset value is, for example, 1. The first timing duration can be the duration obtained by subtracting the start time from the current time.

[0041] S205: If the first timing duration is greater than or equal to a first preset duration, set the connection failure bit of the connection control register to a second preset value to enable the target slot.

[0042] In this step, the first preset duration can be pre-set by the staff according to experimental data or experience, such as 10ms, 20ms, 30ms, etc.

[0043] S206: Detect again whether the hardware components are abnormally connected.

[0044] This step is the same as the method of detecting whether the hardware components are abnormally connected in the above step S201 and will not be elaborated here.

[0045] S207: If the hardware components are still abnormally connected, power off the hardware components and then delay power-on, and repeat the steps from disabling the target slot to detecting whether the hardware components are abnormally connected.

[0046] In this step, powering off the hardware components can include sending a power-on / off signal to the CPLD (Complex Programmable Logic Device) to enable the CPLD to control the hardware components to power off and then power on. There can be a time interval between power off and power on, such as 100ms, 150ms, 200ms, etc. The steps from disabling the target slot to detecting whether the hardware components are abnormally connected can include the above steps S204 to S206.

[0047] S208: If the hardware components are abnormally connected, repeat the steps from disabling the target slot to powering off the hardware components and then delaying power-on until the hardware components are normally connected or repeat n times, where n is a positive integer.

[0048] In this step, the steps from disabling the target slot to powering off the hardware components and then delaying power-on can include steps S204 to S207.

[0049] Among them, n is, for example, 2, 3, 4, etc.

[0050] As can be seen from the description of the above embodiments, after detecting the insertion of a hardware component, the embodiments of the present disclosure detect whether the hardware component is abnormally connected. In the case of abnormal connection, the controller associated with the hardware component is prevented from transmitting data to the hardware component, thereby preventing data corruption, data loss, and hardware damage, restarting the target slot, attempting to restore the connection with the hardware component, powering off and then powering on the hardware component in the case of failed restoration, and executing the process of restarting the target slot again to restore the connection with the hardware component, so as to achieve the effect of active recovery in the case of abnormal connection and protecting the data correctness.

[0051] In a possible implementation manner, after the above step S208, if the hardware component is normally connected, the hot plugging process is normally executed.

[0052] In a possible implementation manner, in the above step S201, if it is detected that a hardware component is inserted into the target slot, detecting whether the hardware component is abnormally connected includes: step S2011 and step S2012.

[0053] S2011: In response to detecting that a hardware component is inserted into the target slot, obtain the bandwidth and transmission rate stored in the connection status register of the target slot.

[0054] In this step, each slot has a corresponding connection status register, which is used to store various information related to the connection of the slot. By reading the data stored in the connection status register, the bandwidth and transmission rate are obtained.

[0055] S2012: Determine whether the hardware component is abnormally connected according to the bandwidth and transmission rate.

[0056] In this step, it may include determining whether the hardware component is abnormally connected according to the change amount of the bandwidth, whether the bandwidth is the same as the preset bandwidth, or the change of the transmission rate.

[0057] As can be seen from the description of the above embodiments, the embodiments of the present disclosure obtain the bandwidth and transmission rate stored in the connection status register of the target slot after inserting the hardware component into the slot, and judge whether there is an abnormal connection by the bandwidth and transmission rate, quickly judge whether the hardware component is abnormal, and reduce the time cost of troubleshooting.

[0058] In a possible implementation manner, the bandwidth and transmission rate are obtained by periodic detection.

[0059] In the above step S2012, determining whether the hardware component is abnormally connected according to the bandwidth and transmission rate includes: steps S12A1 to S12A4.

[0060] S12A1: Determine the number of target detection cycles with a transmission rate lower than a preset transmission rate threshold.

[0061] In this step, it may include calculating the average value of the transmission rate within each detection cycle and determining the cycle with the average value lower than the preset transmission rate threshold as the target detection cycle; it may also include determining the cycle with the lowest transmission rate lower than the preset transmission rate threshold as the target detection cycle.

[0062] For example, if the average transmission rate corresponding to cycle A is 4 GB / s and the preset transmission rate threshold is 6 GB / s, then cycle A is determined as the target detection cycle. Another example, if the minimum value of the transmission rate corresponding to cycle B is 1 GB / s and the preset transmission rate threshold is 4 GB / s, then cycle B is determined as the target detection cycle.

[0063] S12A2: Divide the number of target detection cycles by the total number of detection cycles to obtain a cycle ratio.

[0064] In this step, the total number of detection cycles may be the number of detection cycles included within a period of time.

[0065] For example, if the number of target detection cycles is 5 and the total number of detection cycles is 10, then the cycle ratio is 0.5. Another example, if the number of target detection cycles is 4 and the total number of detection cycles is 20, then the cycle ratio is 0.2.

[0066] S12A3: If the cycle ratio is greater than a preset cycle ratio threshold, determine that the hardware component connection is abnormal.

[0067] In this step, the cycle ratio threshold may be preset by the staff according to experimental data or empirical parameters.

[0068] For example, if the cycle ratio is 0.9 and the cycle ratio threshold is 0.8, then determine that the hardware component connection is abnormal. Another example, if the cycle ratio is 0.8 and the cycle ratio threshold is 0.6, then determine that the hardware component connection is abnormal.

[0069] S12A4: If the bandwidth detected in any detection cycle is different from the preset bandwidth, determine that the hardware component connection is abnormal.

[0070] In this step, the preset bandwidth may be calibrated in advance by the staff, may correspond to the model of the hardware component, or may be jointly determined by the rated bandwidth of the hardware component and the rated bandwidth of the slot.

[0071] As can be seen from the description of the above embodiments, in the embodiments of the present disclosure, by periodically detecting the bandwidth and transmission rate, counting the number of detection periods in which the transmission rate is lower than the preset rate threshold, and dividing by the total number of detection periods, a period ratio is obtained. When the period ratio is greater than the preset period ratio threshold, the time with a lower transmission rate is longer, and it is determined that the connection of the hardware component is abnormal. Or when the bandwidth within the detection period is inconsistent with the preset bandwidth, it is determined that the connection of the hardware component is abnormal, achieving the effect of accurately determining whether the connection of the hardware component is abnormal.

[0072] In a possible implementation manner, in the above step S2012, determining whether the connection of the hardware component is abnormal according to the bandwidth and transmission rate includes: steps S12B1 to S12B4.

[0073] S12B1: Determine the minimum value and average value of the transmission rate.

[0074] In this step, it may include obtaining the minimum value of the transmission rate of the hardware component within a period of time and calculating the average value of the transmission rate during this period of time.

[0075] S12B2: Calculate the difference between the average value and the minimum value.

[0076] In this step, subtract the minimum value from the average value to obtain the difference.

[0077] For example, if the average value is 4 GB / s and the minimum value is 1.5 GB / s, the difference is 2.5 GB / s. Another example, if the average value is 3 GB / s and the minimum value is 1 GB / s, the difference is 2 GB / s.

[0078] S12B3: If the difference is greater than the preset transmission rate difference threshold, determine that the connection of the hardware component is abnormal.

[0079] In this step, the transmission rate difference threshold can be preset by the staff according to experimental data or empirical parameters.

[0080] S12B4: If the bandwidth decreases, determine that the connection of the hardware component is abnormal.

[0081] In this step, for example, if the bandwidth decreases from PCIe 5.0 to PCIe 4.0, it is determined that the connection of the hardware component is abnormal. Another example, if the bandwidth decreases from PCIe 6.0 to PCIe 3.0, it is determined that the connection of the hardware component is abnormal.

[0082] As can be seen from the description of the above embodiments, in the embodiments of the present disclosure, when the difference between the minimum value and the average value of the transmission rate is greater than the preset transmission rate difference threshold or when the bandwidth decreases, it is determined that the connection of the hardware component is abnormal, achieving the effect of accurately determining whether the connection of the hardware component is abnormal and reducing the abnormal detection time.

[0083] In a possible implementation, determining whether a hardware component is abnormally connected according to the bandwidth and the transmission rate includes: step S12C1 and step S12C2.

[0084] S12C1: If the bandwidth decreases, it is determined that the hardware component is abnormally connected.

[0085] This step is similar to the above step S12B4 and will not be elaborated here.

[0086] S12C2: If the transmission rate decreases and the decrease amplitude is greater than a preset amplitude threshold, it is determined that the hardware component is abnormally connected.

[0087] In this step, the amplitude threshold can be preset by the staff according to experimental data or empirical parameters. Judging whether the decrease amplitude is greater than the preset amplitude threshold may include obtaining the minimum value and the average transmission rate of the transmission rate, calculating the difference between the minimum value and the transmission rate, determining the ratio of the difference to the average transmission rate as the decrease amplitude, comparing the decrease amplitude with the preset amplitude threshold, and obtaining the judgment result of whether the decrease amplitude is greater than the preset amplitude threshold.

[0088] As can be seen from the description of the above embodiments, the embodiments of the present disclosure determine that the hardware component is abnormally connected when the bandwidth decreases or the transmission rate decreases and the decrease amplitude is greater than the preset amplitude threshold, achieving the effects of accurately judging whether the hardware component is abnormally connected and reducing the abnormal detection time.

[0089] In a possible implementation, in the above step S202, determining the target controller associated with the hardware component includes:

[0090] S2021: Obtain the identifier of the hardware component and the component identifiers associated with each controller.

[0091] In this step, obtaining the identifier of the hardware component can access the configuration space of the hardware component to read the identifier of the hardware component, or receive the identifier of the hardware component during the hardware initialization process, or use a driver program to obtain the identifier of the hardware component.

[0092] S2022: Determine the controller whose associated component identifier is the same as the identifier of the hardware component as the target controller.

[0093] In this step, for example, if the component identifier associated with controller A is a and the hardware component identifier is also a, then controller A is determined as the target controller. Another example is that if the component identifier associated with controller B is "A00101" and the hardware component identifier is also "A00101", then controller B is also determined as the target controller. There can be one or more target controllers.

[0094] As can be seen from the description of the above embodiments, the embodiments of the present disclosure find the target controller associated with the hardware component by obtaining the identifier of the hardware component and the component identifiers associated with each controller, thereby facilitating the unified control of the controller associated with the hardware component.

[0095] In a possible implementation manner, in step S201 above, if it is detected that a hardware component is inserted into the target slot, it is detected whether the hardware component is abnormally connected, including: step S2011.

[0096] S2011: If it is detected that the occupancy register of the target slot stores a preset field, it is determined that a hardware component is inserted into the target slot, and it is detected whether the hardware component is abnormally connected.

[0097] In this step, if the field stored in the occupancy register of the target slot is detected as "1" or "1xFF", it is determined that a hardware component is inserted into the target slot. If the field stored in the occupancy register of the target slot is detected as "0" or "0xFF", it is determined that no hardware component is inserted into the target slot. The preset field can also be other fields pre-calibrated by the staff, which will not be elaborated here. The method for detecting whether the hardware component is abnormally connected is similar to that in step S201 above, which will not be elaborated here.

[0098] As can be seen from the description of the above embodiments, the embodiments of the present disclosure determine whether a hardware component is inserted into the slot by detecting the field in the occupancy register, so as to judge whether various types of hardware components are inserted into the slot. After detecting that a hardware component is inserted into the slot, it is detected whether the hardware component is abnormally connected, so as to determine the connection status at the first time when the hardware component is connected.

[0099] In a possible implementation manner, in step S208 above, if the hardware component is abnormally connected, the steps of invalidating the target slot until powering down the hardware component and then delaying power-on are repeatedly executed until the hardware component is normally connected or after repeating n times, further including: step S210 to step S212.

[0100] S210: If the hardware component is abnormally connected, determine an alternative hardware component.

[0101] In this step, the method for determining an alternative hardware component may include using other idle hardware components as alternative hardware components, or may include determining other hardware components that are not operating at full load as alternative hardware components.

[0102] S211: Obtain the data to be transmitted.

[0103] In this step, the data to be transmitted may include data that needs to be transmitted to the hardware component but has not been transmitted yet.

[0104] S212: Send the data to be transmitted to the alternative hardware component so that the alternative hardware component processes the data to be transmitted.

[0105] In this step, the data to be transmitted can be transmitted to the alternative hardware component in formats such as messages and data packets.

[0106] As can be seen from the description of the above embodiments, the embodiments of the present disclosure maintain the normal processing of data by determining the alternative hardware component and transmitting the data to be transmitted to the alternative hardware component.

[0107] In a possible implementation, in the above step S210, if the connection of the hardware component is abnormal, determining the alternative hardware component includes: step S2101 and step S2102

[0108] S2101: If the connection of the hardware component is abnormal, obtain the real-time transmission rate of the remaining hardware components.

[0109] In this step, the method for obtaining the real-time transmission rate of the remaining hardware components includes obtaining the real-time transmission rate of the remaining hardware components by reading the log file, and can also obtain the real-time transmission rate of the remaining hardware components through tools such as network testing tools and performance testing tools.

[0110] For example, currently there are 5 hardware components, among which the connection of hardware component A is abnormal, then the remaining 4 hardware components are the remaining hardware components, and obtain the real-time transmission rate of the remaining 4 hardware components.

[0111] S2102: Determine the remaining hardware component with the lowest real-time transmission rate as the alternative hardware component.

[0112] In this step, for example, among the remaining 4 hardware components, the real-time transmission rate of hardware component C is the lowest, then hardware component C is determined as the alternative hardware component.

[0113] As can be seen from the description of the above embodiments, the embodiments of the present disclosure determine the remaining hardware component with the lowest real-time transmission rate as the alternative hardware component by obtaining the real-time transmission rate of the remaining hardware components, so as to select a component with a lower load as the alternative and maintain the load balance between the hardware components.

[0114] In a possible implementation, after the above step S2101, it further includes: step S2103 and step S2104.

[0115] S2103: Obtain the real-time transmission rate and the rated transmission rate of each hardware component.

[0116] In this step, the manner of obtaining the real-time transmission rate of each hardware component can be similar to the above step S2101, which will not be elaborated here. The rated transmission rate can be preset for the hardware component.

[0117] S2104: Determine the hardware component with the largest difference between the real-time transmission rate and the rated transmission rate as the alternative hardware component.

[0118] In this step, it includes calculating the difference between the real-time transmission rate and the rated transmission rate, sorting the differences, and obtaining the hardware component with the largest difference.

[0119] As can be seen from the description of the above embodiments, the embodiments of the present disclosure determine the hardware component with the largest difference between the real-time transmission rate and the rated transmission rate as the alternative hardware component, so as to select the alternative hardware component by comprehensively considering the real-time transmission rate and the data processing ability of the hardware component itself.

[0120] In a possible implementation manner, in the above step S208, if the connection of the hardware component is abnormal, the steps of invalidating the target slot until powering off the hardware component and then delaying power-on are repeatedly executed until the connection of the hardware component is normal or after repeating n times, it further includes: step S220.

[0121] S220: If the connection of the hardware component is normal, send a data transmission recovery instruction to the target controller to enable the target controller to resume data transmission with the hardware component.

[0122] In this step, the data transmission recovery instruction can also be preset. The manner of sending the data transmission recovery instruction to the target controller is similar to the manner of sending the notification transmission instruction in the above step S203, and will not be elaborated here.

[0123] After the connection of the hardware component is restored, send a data transmission recovery instruction to the target controller.

[0124] As can be seen from the description of the above embodiments, the embodiments of the present disclosure send a data transmission recovery instruction to the target controller after the connection of the hardware component is restored to normal, so as to resume normal data transmission to the hardware component.

[0125] In a possible implementation manner, before the above step S201, if it is detected that a hardware component is inserted into the target slot and then it is detected whether the connection of the hardware component is abnormal, it further includes: step S230 to step S234.

[0126] S230: Obtain the occupancy information of the target slot.

[0127] In this step, it can be similar to the above step S2011, read the information stored in the occupancy register of the target slot to obtain the occupancy information.

[0128] S231: If it is determined according to the on-site information that the hardware component has been unplugged, set the connection failure bit of the connection control register of the target slot to a first preset value, disable the target slot, and start timing to obtain a second timing duration.
