Therefore, based on complex links, how to accurately locate the fault location, report the faulty device, and handle the fault source, etc., puts forward higher requirements for a series of fault diagnosis. In terms of link fault location, the DPC (Downstream Port Containment) function provides a rich data source. For example, when a device in the link fails, the status information collected by DPC can quickly identify the fault point. However, due to the complexity of the link, if all devices in the link have the DPC function turned on, the complexity and resource consumption will increase.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] First, several nouns involved in the present invention are analyzed:

[0050] PCIE: Short for PCI Express, high-speed expansion device.

[0051] CPU RootPort: It is the starting point of the PCIE bus. It is connected to the processor or chipset on the motherboard and is responsible for managing and controlling other PCIE devices connected to this port.

[0052] SW bridge: Switch Bridge adapter board, responsible for connecting multiple devices and expanding the coverage of the link.

[0053] End Point PCIE device: The PCIE device at the end of the link refers to the hardware component that actually performs specific functions, such as network cards, graphics cards, sound cards and other hardware devices.

[0054] NVME disk: Non-Volatile Memory Express, is a storage device.

[0055] GPU: Graphics Processing Unit, server graphics card.

[0056] DPC: Downstream Port Containment, is a mechanism for handling error conditions in PCIE links.

[0057] DBF: BUS, Device and Function information of the device, that is, the bus type information, device identification information and function number information of the device.

[0058] It should be noted that: the root node device in this embodiment refers to the CPU RootPort device; the hardware device in this embodiment refers to the PCIE device; the switching device in this embodiment refers to the Switch Bridge device; the port isolation function in this embodiment refers to the DPC function; the terminal device in this embodiment refers to the End Point PCIE device, that is, the terminal PCIE device.

[0059] The present invention is to expand various types of devices through the Switch Bridge adapter board during the development of the AI ​​server. For example: through the Switch Bridge adapter board, 8 NVME hard disks, 8 network cards, 8 GPU cards and other devices can be expanded and connected on the Switch Bridge adapter board. The PCIE device resources loaded on such an AI server are very rich, the PCIE link is very long, and at the same time, the PCIE devices matched with different AI server models have a variety of changing combinations. In this way, in the model of the AI ​​server project, the End Point PCIE device is connected to the CPU RootPort through the Switch Bridge adapter board. The link is very long, and the End Point PCIE device has a variety of types of complex links. Therefore, in the problem of fault diagnosis, how to accurately locate the fault, report the faulty device, and handle the fault source puts forward higher requirements. Under the condition of controlling resource consumption and complexity, it is very important to achieve the fault location performance of the entire complex link by controlling the port isolation function of the device in the complex link.

[0060] The present invention provides a device control method, which locates the positions of various devices based on complex links and applies DPC functions with different strategies to solve the above problems. Figure 1 , Figure 1 A flow chart of a device control method provided by an embodiment of the present invention. The method may include:

[0061] S101: Perform link identification on the link to determine the root node device.

[0062] The link in this embodiment is a complex link of the AI ​​server. A complex link refers to a link with a long link, multiple device types in the link, and multiple device levels. In general, the port isolation function of the root node device can be enabled. Of course, it can also be determined whether to enable it according to the actual situation. Taking into account the complexity of the link, when the root node device and the switching device are in the same link, the system does not know which device is the root node device, so link identification is required to accurately locate the root node device. The root node device is determined first to facilitate traversing the entire link and determining the types of other downstream devices in the link. Specifically, the link information can be read, and the link information includes Socket, Bus, Device, Function, Mmioinfo (memory mapped input / output information), Slotriser (slot allocator) and other information to identify the root node device of the link.

[0063] S102: Identify the device connected to the root node device.

[0064] When the root node device is determined, the root node device is used as the starting point to perform device testing on the downstream devices (i.e., the next-connected devices) of the device in the link to determine the device type of the next-layer node.

[0065] S103: If the downstream device is a hardware device, determine whether to enable a port isolation function of the downstream device according to a first strategy.

[0066] It is understandable that the hardware device is directly connected to the root node device without any switching device in between. Generally, the port isolation function of the hardware device can be enabled. However, in order to meet customer needs, a first strategy of the hardware device is also set, and whether to enable the port isolation function of the hardware device is determined according to the first strategy.

[0067] Furthermore, if the downstream device is a hardware device, determining whether to enable the port isolation function of the downstream device according to the first strategy may include the following steps:

[0068] If the downstream device is in the first whitelist, the port isolation function of the downstream device is enabled;

[0069] If the downstream device is not in the first whitelist, the port isolation function of the downstream device is disabled.

[0070] Specifically, the first strategy in this embodiment is a whitelist strategy. The customer formulates a whitelist according to actual needs. This embodiment does not limit the customization method of the whitelist. For example, the whitelist can be customized according to the device type. For example, if the device type in the whitelist is a GPU and a network card, if the hardware device directly connected to the root node device is a GPU, the port isolation function of the GPU is turned on; if the hardware device directly connected to the root node device is an NVME disk, the port isolation function of the NVME disk is turned off.

[0071] Furthermore, the first whitelist may specifically include hot-swappable devices and devices directly involved in data reading, writing and transmission.

[0072] This embodiment takes into account the devices that are frequently added or removed in systems that support hot plugging, such as servers and data centers. Hot plugging operations may cause exceptions, but the port isolation function can effectively deal with this situation, so hot plug devices can be included in the white list. Key devices that are directly involved in data reading, writing, and transmission, such as storage controllers and network adapters, may cause data damage or loss due to errors in these devices, so port isolation functions are also needed to isolate errors and prevent them from spreading. Therefore, it is very necessary to turn on the port isolation function for hot plugging devices and devices that are directly involved in data reading, writing, and transmission, so that they can effectively deal with abnormal situations caused by hot plugging, and can also isolate errors and prevent them from spreading in time through the port isolation function when data is damaged or lost.

[0073] Furthermore, after disabling the port isolation function of the downstream device, the following steps may also be included:

[0074] Disable the port isolation function of the upper node device connected to the downstream device.

[0075] Specifically, when two devices have a problem connecting, it is not possible to determine whether the problem is with the device itself or with the upper device. Therefore, when shutting down the device, the port isolation function of the upper node device connected to it, that is, the port isolation function of the root node device, must also be shut down.

[0076] S104: If the downstream device is a switching device, the link is identified level by level to determine the terminal device, and whether to enable the port isolation function of the terminal device is determined according to the second strategy.

[0077] When the device connected to the root node device is a switching device, it is necessary to continue to identify, that is, to identify the link step by step until the end of the link. Generally, the end device is generally a hardware device. Although the hardware of the link end device and the hardware of the directly connected root node device are both hardware devices, different strategies need to be formulated due to their different link locations. That is, determine whether to enable the port isolation function of the hardware device according to the second strategy. Generally, the port isolation function of the switching device can also be turned off.

[0078] Further, the step-by-step identification of the link, determining the terminal device, and determining whether to enable the port isolation function of the terminal device according to the second strategy may include the following steps:

[0079] Take the following connected devices as the starting point and identify the link;

[0080] If the downstream device of the downstream device is a switching device, the identification is continued step by step until the hardware device in the link is identified and the hardware device is regarded as the terminal device;

[0081] If the downstream device of the downstream device is a hardware device, the identification is stopped and the hardware device is regarded as the terminal device;

[0082] Determine whether the terminal device is online;

[0083] If it is not online, the terminal device will exit the port isolation function setting;

[0084] If online, determine whether the terminal device is in the second whitelist;

[0085] If the terminal device is in the second whitelist, the port isolation function of the terminal device is enabled;

[0086] If the terminal device is not in the second whitelist, the port isolation function of the terminal device is disabled.

[0087] Specifically, a step-by-step identification strategy is implemented for the link where the switching device is located. For example, the Switch Bridge expansion board BDF:01:00.0 identifies that it is a Bridge, and then identifies the device connected to Bridge BDF:01:00.0. If it is still a Bridge type device, continue to identify step by step until the device connected to the end of this link is found, until all devices are traversed, so as to find the End Point PCIE device (i.e., the end device, which is also a hardware device). For the End Point PCIE device at the end of the Switch Bridge expansion board link, if the End Point PCIE device is in place and is in the white list, the port isolation function of this End Point PCIE device is enabled. This embodiment determines the hardware device at the end of the link by step-by-step identification of the multi-layer link containing the switching device, and determines whether to enable or disable the port isolation function of the hardware device at the end of the link according to the white list and the device status. Such a traversal method can identify all device types and device locations in the entire link, and apply DPC function strategies to them, so as to realize customized fault diagnosis strategies for required devices. Such devices can quickly locate the device fault location and improve system stability and security.

[0088] Furthermore, after the hardware device is used as the terminal device, the following steps may also be included:

[0089] The device between the starting point and the end device is regarded as the link intermediate device, and the port isolation function of the link intermediate device is disabled.

[0090] Specifically, when the device at the end of the link is determined, all the intermediate devices between the end of the link and the starting point belong to nodes without an external End Point (End Point refers to the device or component at the end of the PCIE hierarchy), and the endpoint isolation function of these intermediate devices can be turned off. It needs to be explained that the intermediate device may be a transfer device, or it may be a hardware device with a transfer function, because some hardware devices themselves may have integrated external transfer boards. This means that these devices can establish connections with other devices or components through their built-in transfer boards.

[0091] Furthermore, after the port isolation function of the terminal device is enabled, the following steps may also be included:

[0092] Enable the port isolation function of the upper node device connected to the terminal device.

[0093] Specifically, when there is a problem with the connection between two devices, it is impossible to determine whether it is a problem with the device itself or the upper-level device. Therefore, after passing the second whitelist verification, when the port isolation function of the terminal device is enabled, the port isolation of the upper-level device connected to the terminal device can also be enabled.

[0094] The device control method provided by the embodiment of the present invention is applied to determine the root node device by link identification of the link; identify the downstream device of the root node device; if the downstream device is a hardware device, determine whether to enable the port isolation function of the downstream device according to the first strategy; if the downstream device is a switching device, identify the link step by step, determine the terminal device, and determine whether to enable the port isolation function of the terminal device according to the second strategy. Based on the fault diagnosis function requirements of the complex link of the AI ​​server, the present invention fully combines the characteristics of complex links, such as the long link, many devices, and complex device types of the downstream devices of the complex server, and applies different control strategies after identifying the switching devices and hardware devices connected to the root node device, and turns on and off the port isolation function of the hardware device according to the requirements. This method can accurately identify the device type at each level in the link, and set different fault diagnosis strategies for the hierarchical characteristics of the link where different device types are located. Such a method can realize customized fault diagnosis strategies for required hardware devices through devices that enable port isolation functions in the link while controlling resource consumption and complexity. Based on such port isolation function settings, the location of faulty devices in the link can be further quickly discovered and accurately located, the problem can be quickly solved, and the system stability and security can be improved.

[0095] In order to make the present invention easier to understand, please refer to Figure 2 and Figure 3 . Figure 2 An example flow chart of a device control method provided by an embodiment of the present invention, Figure 3 An example flowchart of another device control method provided by an embodiment of the present invention. Figure 2 It is aimed at the End Point PCIE identification and DPC control of the CPU Root Port; Figure 3 It is aimed at the identification and DPC control of the SW bridge and the End Point PCIE under the SW bridge in the link. This method traverses the link to identify all devices (CPU RootPort, SW bridge, End Point PCIE), as well as the node location of the device in the link. Customize the DPC policy for the CPU RootPort, perform whitelist 1 type identification on the End Point PCIE under the CPU RootPort, and apply the DPC policy of whitelist 1; customize the DPC policy for the SW bridge, perform whitelist 2 type identification on the End Point PCIE under the SW bridge, and apply the DPC policy of whitelist 2.

[0096] The following is a device control method analyzed from the code level:

[0097]

[0098] After this method is applied to this link, the DPC control strategy of each device in the link is as follows:

[0099] (1) Determine that BDF:c0:01.0 is connected to a Switch Bridge and disable the DPC function of BDF:c0:01.0.

[0100] (2) Identify BDF:c3:00.0 as the End Point PCIE device of the Switch Bridge. Identify it as a network card through the EndPoint PCIE device information. The network card is in the whitelist, so enable the DPC function of BDF:c3:00.0.

[0101] (3) Identify that the parent node of the End Point PCIE device of BDF:c3:00.0 is BDF:c2:00.0, and enable the DPC function of c2:00.0.

[0102] (4) The device information of BDF:8F:00.0 connected to BDF:8e:01.0 of CPU Root Port is identified as a network card. The network card is in whitelist 1, so the DPC function of BDF:8F:00.0 is enabled, and the DPC function of BDF:8e:01.0 of CPU Root Port is also enabled.

[0103] (5) The Device information of the End Point PCIE device of BDF:c5:00.0 identifies that it is an NVME disk. The NVME disk is not in the whitelist 2, so the DPC function of BDF:c5:00.0 is turned off.
