The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

"First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components.

As an additional hardware device for computer peripherals, boards are widely used in the computer field. The board uses the bus protocol to communicate with the computer, so as to receive control signals and control commands from the computer, and send feedback information to the computer.

Fig. 1 shows a schematic diagram of an exemplary application scenario according to an embodiment of the present disclosure. As shown in Fig. 1 , the host computer of the computing device may, for example, use a peripheral component interconnect (Peripheral Component Interconnect, PCI) bus or a peripheral component interconnection high-speed A (Peripheral Component Interconnect Express, PCI-e) bus connects multiple boards, and these boards are called PCI boards or PCI-e boards, for example. In FIG. 1 , multiple PCI-e boards are taken as an example. Specifically, Fig. 1 schematically shows 3 PCI-e boards, which are respectively represented as PCI-e-1, PCI-e-2 and PCI-e-3, and the PCI-e boards pass PCI-e The bridge communicates with the host. It can be understood that, the host may also be connected with more or less PCI-e boards, which is not limited here. In addition, Fig. 1 shows that the host computer is connected to the PCI-e board, in other application scenarios, it may also be a PCI board, which is not limited here, for the convenience of description, the board is described as a PCI-e board , but it can be understood that the PCI-e board can be similarly implemented as a PCI board.

PCI-e is a widely used interface, and most motherboard products are equipped with this slot. The PCI-e slot is also the slot type with the largest number of motherboard configurations. On the current popular desktop computer motherboards, ATX-structured motherboards are generally equipped with multiple (such as 5-6) PCI-e slots, while small Some MATX motherboards are also equipped with 2-3 PCI-e slots. Generally, the PCI-e board is connected to the motherboard through the PCI-e slot, which has the feature of plug and play. For example, when the board is inserted into the interface, the system will automatically allocate the resources required by the board. Address, interrupt number, etc., and automatically find the corresponding driver. For example, the PCI-e board can be implemented as a sound card, a network card, a MODEM and other devices.

In addition, each PCI-e board may have only one function (Function), denoted as Fun0. It can also have up to 8 functions, ie realized as a multi-function device (Multi-Fun). Regardless of how many functions the PCI-e board has, each function has its own unique configuration space (Configuration Space) corresponding to it.

Each function in the PCI-e bus is provided with a unique identifier corresponding to it. This identifier can be called bus, device, function (Bus, Device, Function, BDF), and the PCI-e configuration software has the ability to identify the topology logic of the entire PCI-e bus system, as well as each of the buses (Bus), Each device (Device) and each function (Function). As an example, in BDF, the bus occupies 8 bits, the device occupies 5 bits, and the function occupies 3 bits. Thus, the PCI-e board on each slot on the motherboard can be uniquely identified by the BDF.

Generally, one or more monitoring devices are also provided on the board to monitor operating states such as voltage and power. Monitoring equipment is usually used to measure parameters such as board performance, voltage, and temperature. Therefore, in this paper, monitoring equipment can also be expressed as PVT (Process, Voltage and Temperature) equipment, which is schematically shown in Figure 1 A PCI-e board is configured with a monitoring device, wherein the monitoring devices are shown as PVT-1, PVT-2 and PVT-3. As an example, the monitoring device may be implemented as a sensor, such as a voltage sensor or the like, for measuring a voltage parameter. The host computer can realize the data transmission with the PVT device through the system management bus (System Management bus, SMbus) controller, for example, the PVT device can transmit the measured data to the host computer through the SMbus. It can be understood that one PCI-e board can also be configured with multiple PVT devices, which is not limited here.

The connection between the PCI-e board and the configured PVT device can be managed by the firmware program in the board. As shown in Figure 1, the PCI-e board transmits data with the host through the PCI-e bus, and the PVT device transmits data with the host through the SMbus. Therefore, during use, the device management software (such as a baseboard management controller (BMC)) in the host needs to bind the monitoring device with the board to realize status monitoring. In other words, the host needs to know which monitoring device or devices correspond to which board.

In related technologies, the binding between the board card and the monitoring device is usually implemented through hardware configuration. For example, on the backplane of the main chassis, different pull-up and pull-down resistors are configured for different PCI-e slots. After the board is inserted into the PCI-e slot, the electrical connection is made due to the hardware contact, so that the SMbus address of the PVT device can be determined. At the same time, the PCI-e board on each slot has a BDF logo, so that the association between the board and the PVT device can be established to realize the binding between the board and the monitoring device.

However, this hardware design method by configuring different pull-up and pull-down resistors requires additional considerations in hardware design, for example, configuring different resistor values for different slots, and in addition, it also depends on the electrical connection between the board and the slot. The number of devices that the motherboard can support is limited by factors such as physical size and PCI-e board manufacturing process.

Some embodiments of the present disclosure provide a device management method for a computing device, a computing device, an apparatus, and a medium, so as to implement binding among multiple boards and multiple monitoring devices. Utilizing the device management method for computing devices provided by the embodiments of the present disclosure, it is possible to determine the Realize the binding between boards and monitoring devices, that is, determine which or which monitoring devices correspond to the first board currently receiving the enabling signal, so as to establish a matching relationship between multiple boards and multiple monitoring devices. The binding method according to the embodiment of the present disclosure does not depend on the hardware design for the motherboard slot, and is implemented based on software, thus without introducing additional hardware design costs, it can be conveniently implemented based on the measurement characteristics of the monitoring device itself Fast binding of boards and monitoring equipment.

FIG. 2 shows a schematic flowchart of a device management method for a computing device according to an embodiment of the present disclosure, where the computing device may include multiple boards and multiple monitoring devices, such as PCI as shown in FIG. 1 -e-1, PCI-e-2 and PCI-e-3, and PVT-1, PVT-2 and PVT-3, by executing the device management method according to some embodiments of the present disclosure, the host can learn that PCI-e- The matching relationship between 1 and PVT-1, PCI-e-2 and PVT-2, and PCI-e-3 and PVT-3. The specific implementation process of the device management method according to some embodiments of the present disclosure will be described in detail below with reference to FIG. 1 and FIG. 2 .

As shown in FIG. 2 , first at step S101 , an enabling signal is sent to a first board, where the first board may be any one of multiple boards of the computing device. According to some embodiments of the present disclosure, the board may include a Peripheral Component Interconnect (PCI) board or a Peripheral Component Interconnect Express (PCI-e) board, and the board is connected to the computing device through a PCI bridge or a PCI-e bridge. Make a communication connection, such as data transfer with a host computer in a computing device.

For example, the multiple boards may be PCI-e-1, PCI-e-2, and PCI-e-3 shown in FIG. 1 , and the first board may be any one of the above three boards. As an example, the first board may be PCI-e-1, that is, in step S101, for example, the host may send an enabling signal to PCI-e-1. In addition, after determining the monitoring device associated with the first board (PCI-e-1) according to the following steps S102 and S103, the host computer can also report to any board in PCI-e-2 and PCI-e-3 To send the enable signal, for example, PCI-e-2 and PCI-e-3 may be used as the first board in turn, so as to determine the monitoring devices associated with the boards one by one. The steps performed for different boards are similar, and the following description takes the first board being PCI-e-1 as an example. It can be understood that the described method can be similarly applied to other boards. The enabling signal may be a control signal for controlling the PCI-e-1 to enter a certain special mode, such as entering a high-performance mode, and its specific implementation will be described below.

Next, in step S102, at least one measurement value measured by each monitoring device in the plurality of monitoring devices is obtained, so as to obtain a plurality of measurement values of the plurality of monitoring devices. According to some embodiments of the present disclosure, as shown in FIG. 1 , multiple monitoring devices (PVT-1, PVT-2 and PVT-3) can transmit data signals with computing devices through a system management bus (SMbus) controller.

According to some embodiments of the present disclosure, for example, the host may send a monitoring control signal to a plurality of monitoring devices, wherein the monitoring control signal is used to control the plurality of monitoring devices to measure at least one measurement value respectively, and send the measured value to the computing device at least one measurement. That is to say, after sending an enable signal to PCI-e-1, thereby instructing PCI-e-1 to enter a high-performance mode, for example, the host can then send a monitoring control signal to multiple monitoring devices, so that each monitoring device The devices each measure at least one measured value. As an example, corresponding to the enable signal being a control signal instructing PCI-e-1 to enter high-performance mode, the host may instruct each monitoring device to measure at least one voltage measurement respectively, and receive each monitoring device, such as via the SMbus controller. At least one voltage measurement measured by the device respectively.

Finally, as shown in FIG. 2 , in step S103 , the monitoring device associated with the first board is determined among the plurality of monitoring devices based on the multiple measurement values and the enabling signals.

According to some embodiments of the present disclosure, determining the monitoring device associated with the first board among the plurality of monitoring devices based on the plurality of measurement values and the enabling signal (that is, step S103) may include: determining among the plurality of measurement values The measurement value corresponding to the enabling signal is used as the matching measurement value; the monitoring device reporting the matching measurement value is determined as the first monitoring device; and the first monitoring device is determined as the monitoring device associated with the first board.

As an example, after receiving the monitoring control signal, PVT-1, PVT-2 and PVT-3 may each measure at least one measurement value, eg denoted V1, V2 and V3. Then, PVT-1, PVT-2 and PVT-3 can report their measured values V1, V2 and V3 to the host via SMbus. The host can determine the measurement value corresponding to the enable signal from V1, V2, and V3 as the matching measurement value. For example, the matching measurement value can be V1, so the host will report the measurement value V1 to the monitoring device, that is, PVT- 1 is determined as the first monitoring device, and the first monitoring device is determined as the monitoring device associated with the first board. That is to say, the host can determine that the monitoring device PVT-1 is a device configured to monitor the running status of the board PCI-e-1, that is, determine the relationship between the board PCI-e-1 and the monitoring device PVT-1. corresponding relationship.

According to some embodiments of the present disclosure, as an example, the enable signal may be used to control the first board to enter a special performance mode, and corresponding to the enable signal, the multiple measured values may be multiple voltage measured values.

Specifically, according to some embodiments of the present disclosure, determining the monitoring device associated with the first board among the plurality of monitoring devices based on the plurality of measurement values and the enabling signal may include: determining the maximum voltage measurement value; and determining the monitoring device reporting the maximum voltage measurement value as the first monitoring device; determining the first monitoring device as the monitoring device associated with the first board.

As an example, the above-mentioned special performance mode may be a high-performance mode, and after the board enters the high-performance mode, its voltage value will increase. Based on this feature, the host can instruct the monitoring device to report the measured voltage value, and then determine the monitoring device associated with the first board currently entering the high-performance mode based on the voltage value. Thus, the host can determine the monitoring device associated with the first board based on the multiple voltage measurements obtained from the multiple monitoring devices and the enable signal indicating that the first board enters the high performance mode.

The foregoing determination of the association between the board and the monitoring device based on the enabling signal for controlling the first board to enter the high-performance mode and the voltage value of the monitoring device may be an example according to some embodiments of the present disclosure.

In other embodiments according to the present disclosure, the enabling signal can also be implemented as other control signals. As an example, the enabling signal can also instruct the first board to enter a low-performance mode, that is, the special performance mode is low performance mode, then the host can instruct the monitoring device to measure the voltage value, and can determine the monitoring device with the lowest voltage value to be associated with the first board. As another example, the enabling signal may also instruct the first board to enter a high-frequency operation mode, and then the host may instruct the monitoring device to measure the frequency value, and determine the monitoring device with the highest frequency value as being related to the first board couplet. In other examples, the enabling signal can also be implemented in other forms, which will not be listed here. It can be understood that the host can correspondingly instruct the monitoring device to measure the corresponding and then determine the monitoring device associated with the first board according to the measured value.

Thus, by using the device management method according to the embodiment of the present disclosure, it is possible to realize the monitoring of The binding between boards and monitoring devices is to determine which or which monitoring devices correspond to the first board currently receiving the enabling signal, so as to establish a matching relationship between multiple boards and multiple monitoring devices. The binding method according to the embodiment of the present disclosure does not depend on the hardware design for the motherboard slot, and is implemented based on software, thus without introducing additional hardware design costs, it can be conveniently implemented based on the measurement characteristics of the monitoring device itself Fast binding of boards and monitoring equipment.

According to some embodiments of the present disclosure, the device management method for a computing device may further include: sending an enumeration control signal to a board connected to the computing device, wherein the enumeration control signal is used to control the board connected to the computing device The computing device performs device enumeration one by one, so that the computing device recognizes multiple boards. Through this step, the host can recognize multiple connected boards.

According to some embodiments of the present disclosure, the device management method for a computing device may further include: acquiring a device identifier of each monitoring device among the plurality of monitoring devices, and assigning a device address to each monitoring device based on the device identifier; And acquire the first board identifier of the first board.

As an example, the device identifier of each monitoring device may be a unique identifier (UDID) reported by the monitoring device via SMbus, for example, according to the Address Resolution Protocol (Address Resolution Protocol, ARP) in the SMbus protocol, which requires each monitoring Each device provides its unique identification code UDID, and then assigns an address (for example, ADD_1) according to the UDID. As an example, the unique identification code UDID may be generated by generating a pseudo-random number. As another example, the UDID may also be generated in other ways, which is not limited here. The first board identifier may be, for example, the above-mentioned BDF identifier of the board, which may uniquely characterize the board.

According to some embodiments of the present disclosure, the device management method for a computing device may further include: after determining the monitoring device associated with the first board among the plurality of monitoring devices based on the plurality of measurement values and the enabling signal, Based on the first board identifier (for example, BDF_1) of the first board and the device address (for example, ADD_1) of the monitoring device associated with the first board, establish the first board and associate with the first board The mapping table between the monitoring devices. That is to say, the host can associate the first board card PCI-e-1 with the first monitoring device PVT-1. During subsequent operation, the host may determine, for example, based on the mapping table, that the measurement parameters reported by the first monitoring device PVT-1 correspond to the first board card PCI-e-1, thereby implementing device management.

FIG. 3 shows an application flow chart of a device management method according to an embodiment of the present disclosure. In the example in FIG. 3 , the device according to the embodiment of the present disclosure is described by taking the enable signal as an instruction board to enter a high-performance mode as a specific example. The implementation process of the management method.

As shown in FIG. 3 , firstly, the host performs a power-on operation, for example, through a power-on reset circuit, which can ensure that the device is initialized to a known state after power is applied. Next, in step S301, the host can send enumeration control signals to the PCI-e boards inserted into the PCI-e slots, so that each board is enumerated by the host one by one, so that the host can identify multiple boards card, thus identifying the number N of multiple board cards. For example, in the scenario shown in FIG. 1 , there are boards PCI-e-1, PCI-e-2, and PCI-e-3, that is, N=3 boards are currently connected in total. In addition, through device enumeration, the host can also learn the identifier BDF of each board, for example, BDF_1, BDF_2 and BDF_3.

In step S302, an address is allocated to the PVT device. For example, the host can allocate the address of the PVT device according to the UDID reported by each PVT device. For example, in the scene shown in Figure 1, M=3 monitoring devices are shown in total, represented as PVT-1, PVT-2 and PVT-3, each monitoring device can report its identifier UDID_1, UDID_2 and UDID_3 respectively, Then, the host can assign addresses to the monitoring devices based on the identifiers UDID_1, UDID_2 and UDID_3, denoted as ADD_1, ADD_2 and ADD_3, for example.

It can be understood that, the method of the present disclosure does not limit the execution order of the above steps S301 and S302, for example, step S302 may be executed first and then step S301, and no limitation is set here.

As shown in Figure 3, in step S303, the host can send an enable signal to the PCI-e-i board, wherein, for ease of understanding, i represents the sequence number of the current board, and in the initial stage, i can be equal to 1, that is to say The device management method according to the present disclosure is executed starting from the PCI-e-1 board.

In step S304, based on the received enable signal, the board card PCI-e-i will enter the high-performance mode. Then, in step S305, the host can instruct each PVT device to measure the voltage value, and send the measured voltage value V1-VM to the host via SMbus. In the example application scenario shown in FIG. 1, M=3, thus , the host will receive the voltage value V1-V3.

In step S306, the host may determine the maximum voltage measurement value, assuming V1, among the voltage measurement values (ie V1-V3) based on the enable signal. Therefore, in step S307, the PVT-1 reporting the maximum voltage measurement value V1 may be determined to be associated with the board PCI-e-1. For example, the first board can be established based on the first board identifier BDF_1 of the first board PCI-e-1 and the device address ADD_1 of the monitoring device PVT-1 associated with the first board PCI-e-1. A mapping table between the card and the monitoring device associated with the first board. Based on the mapping table, it can be determined that the device PVT-1 is associated with the board PCI-e-1, that is, the device PVT-1 monitors the running status of the board PCI-e-1.

In step S308, it is determined whether i is equal to the number N of boards, and if it is determined that i is equal to N, it means that the above device management steps according to the embodiment of the present disclosure have been performed for all boards PCI-e-1 to PCI-e-N, That is, execution of the device management method may end. If it is determined that i is not equal to N, then enter step S309, so that the value of i increases by 1 (i=i+1), and return to execute step S303, that is, similarly execute steps S303-S307 for board PCI-e-2, Until the management steps are completed for all boards.

According to the process shown in FIG. 3 , it is possible to enable the host to realize the control of the board according to the correspondence between the enable signal sent to the first board among the multiple boards and the measured values measured by the multiple monitoring devices. The binding with the monitoring devices is to determine which or which monitoring devices correspond to the first board currently receiving the enabling signal, so as to establish a matching relationship between multiple boards and multiple monitoring devices. In addition, the binding method according to the embodiments of the present disclosure does not depend on the hardware design for the main board slot in the related art, thus without introducing additional hardware design costs, so that the board can be conveniently implemented based on the measurement characteristics of the monitoring device itself. Fast binding of the card to the monitoring device.

According to another aspect of the present disclosure, a computing device is also provided. The computing device may include a host, multiple boards, and multiple monitoring devices. The host includes at least a baseboard management controller for monitoring multiple boards and multiple monitoring devices. A monitoring device is bound.
