[0047] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0049] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0050] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] With the continuous development of computer technology, PCIe (peripheral component interconnect express, a high-speed serial computer expansion bus standard) devices have emerged. PCIe devices (i.e. PCIe switches, which are used to provide expansion or aggregation capabilities and allow more devices to be connected to a PCIe port) are point-to-point connections. Multiple endpoint devices (EP, Endpoint) can be connected to PCIe devices, and endpoint devices are used to implement specific business functions. If a large number of endpoint devices need to be connected to a PCIe device, the PCIe device needs to be cascaded in multiple levels to access more PCIe devices. At this time, if a port on a PCIe device or a link corresponding to the PCIe device fails, the PCIe device needs to be repaired.

[0052] Among them, the process of device repair includes the process of removing the endpoint device connected to the PCIe device and the port on the PCIe device, and the process of accessing the endpoint device connected to the PCIe device and the port on the PCIe device. In the traditional technology, the removal process starts from the specified PCIe device, traverses the lowest PCIe device in depth-first order, and traces back one by one until all endpoint devices and ports are removed serially in a bottom-to-top order. In the traditional technology, the access process is to enumerate the first device from the specified bus in a depth-first manner, and enumerate from the device in sequence, so as to serially access all endpoint devices and ports to the PCIe device in a top-to-bottom order to build a complete PCI device topology tree. Therefore, the traditional technology uses a single task serial execution method to perform the removal and access process. When multiple PCIe switches are cascaded and there are many cascaded EPs, the process of device repair takes a long time. In addition, the ports on the PCIe switch do not carry services, so the removal and access operations of the ports on the PCIe device in the traditional technology are not necessary, and the time consumption of the device repair process is increased. In summary, the traditional device repair method has the problem of low repair efficiency. After introducing the background technology of the device repair method provided by the embodiment of the present application, the implementation environment involved in the device repair method provided by the embodiment of the present application will be briefly described below.

[0053] The device repair method provided in the embodiment of the present application can be applied to Figure 1In the computer device shown. The computer device can be a terminal or a server, and the computer device includes a processor, a memory, an input / output interface, a communication interface, a display unit and an input device. The processor, the memory and the input / output interface are connected through a system bus, and the communication interface, the display unit and the input device are connected to the system bus through the input / output interface. The processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The input / output interface of the computer device is used to exchange information between the processor and the external device. The communication interface of the computer device is used to communicate with an external terminal in a wired or wireless manner, and the wireless manner can be implemented through WIFI, a mobile cellular network, NFC (near field communication) or other technologies. When the computer program is executed by the processor, a device repair method is implemented. The display unit of the computer device is used to form a visually visible picture, which can be a display screen, a projection device or a virtual reality imaging device. The display screen can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer device can be a touch layer covering the display screen, or a button, trackball or touchpad set on the computer device shell, or an external keyboard, touchpad or mouse.

[0054] Those skilled in the art will understand that Figure 1 The structure shown in the figure is only a block diagram of a part of the structure related to the scheme of the present application, and does not constitute a limitation on the computer device to which the scheme of the present application is applied. The specific terminal may include more or fewer components than shown in the figure, or combine certain components, or have a different arrangement of components.

[0055] In one embodiment, Figure 2 As shown, a device repair method is provided, which is applied to Figure 1 The computer device in the example is used to illustrate, including the following steps:

[0056] S201, assigning a corresponding repair task to a target port device in a port device system; the port device system includes a plurality of cascaded port devices and endpoint devices connected to each port device; the repair task includes a plurality of sub-repair tasks.

[0057] Among them, the port device system may include multiple cascade-connected port devices (i.e., PCIe switches) and multiple endpoint devices EP connected to each port device, each port device includes an upstream port UP (Upstream port, a port connected to an upstream device in a PCIe switch) and multiple downstream ports DP (Downstream port, a port connected to a downstream device in a PCIe switch), optionally, the downstream port DP may be connected one-to-one with the endpoint device EP, or the downstream port DP may also be connected to the upstream port UP in the next port device in the port device system. The multiple cascade-connected port devices include a target port device, which refers to the port device that is closest to the CPU (Central Processing Unit). Generally, the target port device is a port device directly connected to the CPU. The repair task includes multiple sub-repair tasks.

[0058] In the embodiment of the present application, the computer device can determine the port device whose uplink port UP is directly connected to the RP (Root port, the root port directly connected from the CPU) from the multiple port devices in the port device system, and determine the port device as the target port device. Thus, the computer device can assign the corresponding repair subtask to the RP corresponding to the target port device, wherein the repair subtask corresponding to the RP is the main task, which is responsible for the management and control of the overall repair process.

[0059] S202, executing a plurality of sub-repair tasks according to the connection relationship between the target port device and the endpoint device, and the connection relationship between the target port device and other port devices, so as to repair the port device system.

[0060] In the embodiment of the present application, the computer device can determine the connection relationship between the target port device and the endpoint device, and the connection relationship between the target port device and the other port devices, according to whether the target port device is connected to the endpoint device or to other port devices. Thus, the computer device can assign corresponding repair subtasks to each downstream port DP in the target port device according to the connection relationship between the target port device and the endpoint device, and the connection relationship between the target port device and other port devices, so that the sub-repair tasks corresponding to each downstream port DP can be executed in parallel to repair the port device system. Optionally, the computer device can assign different sub-repair tasks to each downstream port DP in the target port device, so as to execute multiple different sub-repair tasks in parallel; or, the computer device can also assign different sub-repair tasks to different types of downstream ports DP in the target port device, so as to execute multiple sub-repair tasks in parallel. Among them, different types of downstream ports DP may include but are not limited to downstream ports DP connected to the endpoint device EP, or downstream ports DP connected to other port devices, etc. Of course, the embodiment of the present application does not limit the specific implementation method of assigning sub-repair tasks.

[0061] In the above-mentioned device repair method, a corresponding repair task is assigned to a target port device in a port device system; the port device system includes a plurality of cascade-connected port devices and endpoint devices connected to each port device; the repair task includes a plurality of sub-repair tasks; and according to the connection relationship between the target port device and the endpoint device, and the connection relationship with other port devices, a plurality of sub-repair tasks are executed to repair the port device system. In the case where there are a plurality of cascade-connected port devices and a plurality of endpoint devices in the port device system, the embodiment of the present application can repair the port device system by executing a plurality of sub-repair tasks corresponding to the target port device in parallel, which can ensure that a plurality of sub-repair tasks corresponding to the same port device can be executed simultaneously, and the efficiency of device repair can be improved.

[0062] In one embodiment, a method for executing multiple sub-repair tasks in parallel is provided, namely, "executing multiple sub-repair tasks according to the connection relationship between the target port device and the endpoint device, and the connection relationship between the target port device and other port devices" in the above S202. Figure 3 As shown, including:

[0063] S301, determining a first downstream port and a second downstream port in a target port device according to a connection relationship between the target port device and an endpoint device, and a connection relationship between the target port device and other port devices; the first downstream port is a port connected to a next port device, and the second downstream port is a port connected to an endpoint device.

[0064] In the embodiment of the present application, the computer device can determine whether the downlink port DP in the target port device is connected to other port devices in the port device system according to the connection relationship between the target port device and other port devices, and determine the first downlink port according to the downlink port in the target port device connected to the next port device in the port device system. Also, the computer device can determine whether the downlink port DP in the target port device is connected to the endpoint device according to the connection relationship between the target port device and the endpoint device, and determine the second downlink port according to the downlink port in the target port device connected to the endpoint device. The first downlink port is a port connected to the next port device, the second downlink port is a port connected to the endpoint device, and the first downlink port and the second downlink port are different types of downlink ports.

[0065] S302: Allocate a corresponding first sub-repair task to the first downlink port, and allocate a corresponding second sub-repair task to the second downlink port.

[0066] In the embodiment of the present application, the computer device can pre-set sub-repair tasks corresponding to different types of downstream ports, wherein the sub-repair tasks corresponding to different types of downstream ports are different, and the sub-repair tasks include a first sub-repair task and a second sub-repair task. Thus, the first sub-repair task corresponding to the first downstream port can be assigned to the first downstream port, and the second sub-repair task corresponding to the second downstream port can be assigned to the second downstream port.

[0067] S303, executing the first sub-repair task and the second sub-repair task.

[0068] In the embodiment of the present application, the computer device can execute the first sub-repair task corresponding to the first downstream port and the second sub-repair task corresponding to the second downstream port in parallel. Optionally, the computer device can synchronously execute the first sub-repair task and the second sub-repair task at a fixed time; or, the computer device can also synchronously execute the first sub-repair task and the second sub-repair task in real time. Of course, the embodiment of the present application does not limit the specific implementation method for executing the first sub-repair task and the second sub-repair task in parallel.

[0069] In this embodiment, different types of downstream ports can be accurately determined based on the connection relationship between the target port device and the endpoint device, as well as the connection relationship between the target port device and other port devices. Therefore, corresponding sub-repair tasks can be respectively assigned to different types of downstream ports, and the first sub-repair task and the second sub-repair task can be executed in parallel, which can ensure that multiple sub-repair tasks corresponding to the same port device can be executed simultaneously, and the efficiency of device repair can be improved.

[0070] In one embodiment, a method for implementing the first sub-repair task is provided, that is, implementing the first sub-repair task includes:

[0071] The next port device is used as a new target port device, and the step of allocating a corresponding repair task to the target port device in the port device system is returned to be executed.

[0072] In an embodiment of the present application, after the computer device assigns the first sub-repair task corresponding to the first downstream port to the first downstream port, it can use the next port device connected to the first downstream port as the new target port device, and return to execute the step of assigning the corresponding repair task to the target port device in the port device system. That is, it can be understood that multiple new sub-repair tasks can be configured for the new target port device, and the new first downstream port and the new second downstream port in the new target port device can be determined according to the connection relationship between the new target port device and the endpoint device, and the connection relationship with other port devices. Thus, from the multiple new sub-repair tasks, the corresponding new first sub-repair task can be assigned to the new first downstream port, and the corresponding new second sub-repair task can be assigned to the new second downstream port. After that, the new first sub-repair task and the new second sub-repair task are executed in parallel until all downstream ports in the port device system are assigned corresponding sub-repair tasks, and the sub-repair tasks of all downstream ports are executed in parallel.

[0073] In this embodiment, the next port device can be used as a new target port device, and the step of assigning a corresponding repair task to the target port device in the port device system can be returned to execute. Corresponding sub-repair tasks can be assigned to all downstream ports in the port device system, and sub-repair tasks of all downstream ports in the same port device can be executed in parallel, thereby improving the efficiency of equipment repair.

[0074] In one embodiment, a method for performing the second sub-repair task is provided, that is, performing the second sub-repair task, such as Figure 4 As shown, including:

[0075] S401: Remove an endpoint device connected to the second downstream port.

[0076] In the embodiment of the present application, the computer device can call the Linux kernel interface to remove the endpoint device connected to the second downstream port, so as to remove the endpoint device EP from the initial PCI device tree, and trigger the service driver corresponding to the endpoint device EP to execute the remove function, and delete the software resources. In addition, the computer device can also set a completion mark after the removal is completed. In this way, after all the endpoint devices connected to the second downstream ports are removed, the PCI device tree only includes a plurality of cascaded port devices and the upstream port UP and downstream port DP of each port device. Among them, the initial PCI device tree includes a plurality of cascaded port devices, the upstream port UP and downstream port DP of each port device, and the endpoint device EP connected to each port device, that is, the embodiment of the present application only needs to remove the endpoint device EP in the initial PCI device tree, without removing the upstream port UP and downstream port DP of each port device, which can improve the efficiency of the removal process; and after removing the endpoint device, each port device is still retained on the initial PCI device tree, which can retain the topological structure of the initial PCI device tree foundation, and lay the foundation for the parallel access of the next endpoint device.

[0077] S402: Initialize the upstream port, the first downstream port, and the second downstream port of the target port device.

[0078] In the embodiment of the present application, optionally, the computer device can set preset default values ​​for the registers in the upstream port, the first downstream port, and the second downstream port of the target port device to implement initialization processing of the upstream port, the first downstream port, and the second downstream port of the target port device; or, the computer device can initialize the upstream port, the first downstream port, and the second downstream port of the target port device by backfilling the register value. Of course, the embodiment of the present application does not limit the specific implementation method of the initialization processing.

[0079] S403: Access an endpoint device connected to the second downstream port.

[0080] In an embodiment of the present application, after all port devices are initialized, the computer device can determine the second downstream port that is not connected to the opposite device, and call the Linux kernel interface to enumerate the target port device and the following port devices, so as to access or mount the endpoint device connected to the second downstream port to the PCI device tree, thereby rebuilding the PCI device tree, and triggering the probe function registered by each endpoint device driver to perform device detection and enable business functions. In addition, the computer device can also set a completion mark after the access is completed. After all endpoint devices have completed the access process, the computer device can traverse the PCIe switch to enable, and configure various properties to complete the entire repair process. Among them, the embodiment of the present application only needs to access the endpoint device EP, without accessing the upstream port UP and downstream port DP of each port device, which can improve the efficiency of the access process.

[0081] In this embodiment, the endpoint device connected to the second downstream port can be removed in parallel, and then the upstream port, the first downstream port and the second downstream port of the target port device after the removal operation are initialized in parallel. After that, the endpoint device connected to the second downstream port is connected to the PCI device tree in parallel. In this way, the repair process can be executed in parallel, thereby improving the efficiency of device repair.

[0082] In one embodiment, an implementation of the initialization process is provided, that is, the “initialization process is performed on the upstream port, the first downstream port, and the second downstream port of the target port device” in the above S402, including:

[0083] Reset the target port device.

[0084] The values ​​of the upstream port, the first downstream port and the second downstream port in the register are updated to initialize the upstream port, the first downstream port and the second downstream port.

[0085] In the embodiment of the present application, after all the endpoint devices connected to the second downstream ports are removed, the computer device can store the values ​​of the first 64 bytes of registers in the configuration space of the upstream port, the first downstream port, and the second downstream port of the target port device. After that, the target port device can be reset and un-reset, and after the link is established, the values ​​of the key registers stored in advance are backfilled to the corresponding upstream port, the first downstream port, and the second downstream port in parallel. In this way, the values ​​of the upstream port, the first downstream port, and the second downstream port in the registers can be updated in parallel to initialize the upstream port, the first downstream port, and the second downstream port.

[0086] In this embodiment, after the target port device is reset, the upstream port, the first downstream port and the second downstream port can be initialized by backfilling the values ​​of the key registers stored in advance to the corresponding upstream port, the first downstream port and the second downstream port in parallel. In this way, the resource attributes of the configuration items can be correctly configured to ensure that each port of the target port device can be correctly identified, and there is no need to remove and connect the ports of the target port device from the initial PCI device tree, which can further improve the efficiency of device repair.

[0087] In one embodiment, a method for determining the first downstream port and the second downstream port is provided, that is, the step of “determining the first downstream port and the second downstream port in the target port device according to the connection relationship between the target port device and the endpoint device, and the connection relationship between the target port device and other port devices” in the above S301 includes:

[0088] According to the connection relationship between the target port device and other port devices connected in cascade, a downlink port of the target port device connected to the next port device is used as the first downlink port.

[0089] According to the connection relationship between the target port device and the endpoint device, a downlink port of the target port device connected to the endpoint device is used as the second downlink port.

[0090] In the embodiment of the present application, the computer device can determine whether the downlink port DP in the target port device is connected to other port devices in the port device system according to the connection relationship between the target port device and other port devices. If the downlink port DP in the target port device is connected to other port devices in the port device system, the port device connected to the downlink port DP in the target port device can be determined as the next port device, and the downlink port in the target port device connected to the next port device can be determined as the first downlink port. Also, the computer device can determine whether the downlink port DP in the target port device is connected to the endpoint device according to the connection relationship between the target port device and the endpoint device. If the downlink port DP in the target port device is connected to the endpoint device, the downlink port in the target port device connected to the endpoint device can be determined as the second downlink port.

[0091] In this embodiment, according to the connection relationship between the target port device and other port devices connected in cascade, the downlink port of the target port device connected to the next port device can be accurately taken as the first downlink port; and according to the connection relationship between the target port device and the endpoint device, the downlink port of the target port device connected to the endpoint device can be accurately taken as the second downlink port. In this way, the first downlink port and the second downlink port can be accurately determined.

[0092] Based on all the above embodiments, the present application also provides a complete device repair method, such as Figure 5 As shown, the method includes:

[0093] S21, assigning a corresponding repair task to a target port device in a port device system; the port device system includes a plurality of cascaded port devices and endpoint devices connected to each port device; the repair task includes a plurality of sub-repair tasks;

[0094] S22, according to the connection relationship between the target port device and other port devices connected in cascade, taking the downlink port of the target port device connected to the next port device as the first downlink port; the first downlink port is the port connected to the next port device;

[0095] S23, according to the connection relationship between the target port device and the endpoint device, taking the downlink port of the target port device connected to the endpoint device as the second downlink port; the second downlink port is the port connected to the endpoint device;

[0096] S24, assigning a corresponding first sub-repair task to the first downlink port, and assigning a corresponding second sub-repair task to the second downlink port;

[0097] S25, taking the next port device as a new target port device, and returning to execute the step of allocating a corresponding repair task to the target port device in the port device system;

[0098] S26, removing the endpoint device connected to the second downstream port;

[0099] S27, after all the endpoint devices connected to the second downstream ports are removed, resetting the target port device;

[0100] S28, updating the values ​​of the upstream port, the first downstream port, and the second downstream port in the register to initialize the upstream port, the first downstream port, and the second downstream port;

[0101] S29, accessing the endpoint device connected to the second downstream port.

[0102] For example, Figure 6 As shown, Figure 61 is an example diagram of a port device system in an embodiment. The port device system may include two cascade-connected port devices SW0 and SW1, and the port device SW0 includes UP0, DP1, DP2, and DP3, and the port device SW1 includes UP1, DP4, DP5, and DP6. UP0 is connected to RP in the CPU, DP1 in the port device SW0 is connected to UP1 in the port device SW1, DP2 is connected to EP1, DP3 is connected to EP2, DP4 is connected to EP3, DP5 is connected to EP4, and DP6 is connected to EP5.

[0103] For example, Figure 7 As shown, Figure 7 In one embodiment Figure 6 The corresponding device repair method flowchart is shown in FIG. Among them, the repair subtask includes a removal subtask and an access subtask. Figure 6 and Figure 7 As shown, the computer device can assign a repair subtask task1 to the RP corresponding to SW0, and S501, traverse each downstream port DP of SW0, assign a removal subtask task2 to DP1, assign a removal subtask task3 to DP2, and assign a removal subtask task4 to DP3. S502, detect whether the opposite device of each downstream port DP in SW0 is a port device, S503, if the opposite device of the downstream port DP is an EP, such as DP2 and DP3, then EP1 corresponding to DP2 and EP2 corresponding to DP3 can be removed; S504, if the opposite device of the downstream port DP is the port device SW1 of the next cascade, then SW1 can be determined as the new SW0, and return to execute S501, that is, traverse each downstream port DP of SW1, assign removal subtask task5 to DP4, assign removal subtask task6 to DP5, and assign removal subtask task7 to DP6. Thus, when it is detected that the opposite device of each downstream port DP in SW1 is an EP, EP3 corresponding to DP4, EP4 corresponding to DP5, and EP5 corresponding to DP6 can be removed. Among them, if Figure 8 As shown, Figure 8 This is a schematic diagram of the relationship between the repair subtasks in an embodiment, task1 is the parent task of task2, task3, and task4, task2 is the parent task of task5, task6, and task7. It should be noted that the repair subtasks corresponding to the same port device are executed in parallel. For example, task2, task3, and task4 can be executed in parallel, and task5, task6, and task7 can be executed in parallel. Only after task5, task6, and task7 are all completed, can it be confirmed that task2, the parent task of task5, task6, and task7, is completed.

[0104] After all removal subtasks are executed, S505, the computer device can reset each port device and update the values ​​of the upstream port, the first downstream port and the second downstream port in the register to initialize the upstream port, the first downstream port and the second downstream port. After the initialization process is completed, S506, the computer device can traverse each downstream port DP of SW0, assign access subtask task2 to DP1, assign access subtask task3 to DP2, and assign access subtask task4 to DP3. S507, detect whether the opposite end of each downstream port DP in SW0 is connected to a port device, S508, if there is no device at the opposite end of the downstream port DP, such as DP2 and DP3, then EP1 corresponding to DP2 and EP2 corresponding to DP3 can be reset, and EP1 corresponding to DP2 and EP2 corresponding to DP3 can be enumerated, and EP1 and EP2 can be mounted on the PCI device tree respectively; S509, if the opposite end of the opposite device of the downstream port DP is connected to the port device SW1 of the next cascade, then SW1 can be determined as the new SW0, and return to execute S506, that is, traverse each downstream port DP of SW1, assign access subtask task5 to DP4, assign access subtask task6 to DP5, and assign access subtask task7 to DP6, so that, when it is detected that there is no device at the opposite end of each downstream port DP in SW1, EP3 corresponding to DP4, EP4 corresponding to DP5, and EP5 corresponding to DP6 can be accessed until all access subtasks are executed.

[0105] In the above device repair method, a corresponding repair task is assigned to the target port device in the port device system; the port device system includes multiple cascaded port devices and endpoint devices connected to each port device; the repair task includes multiple sub-repair tasks; according to the connection relationship between the target port device and the endpoint device, and the connection relationship with other port devices, multiple sub-repair tasks are executed to repair the port device system. In the case where there are multiple cascaded port devices and multiple endpoint devices in the port device system, the embodiment of the present application can repair the port device system by executing multiple sub-repair tasks corresponding to the target port device in parallel, which can ensure that multiple sub-repair tasks corresponding to the same port device can be executed at the same time, and the efficiency of device repair can be improved. For example, assuming that there are N EP devices to be repaired, and the time for each EP device to remove and connect to the driver processing is M, then the total repair time of serial processing in the related art is N * M * 2; after adopting the embodiment of the present application, N devices are processed in parallel, and the total repair time is M * 2, so compared with the related art, the repair efficiency in the present application is improved by N times, and the more cascaded port devices, the more obvious the repair efficiency is.
