The device resource configuration mainly refers to operations such as adding, replacing, or upgrading a device, wherein hot plugging is A device resource configuration method.

A multi-processor system refers to a computer system that includes multiple processors. Due to the large size of a multi-processor system, there is a higher requirement for hot plugging of devices.

When the device is hot swapped, the processor in the system that can handle hot swapping of the device interrupts the current execution of the service, and performs hot plugging operation by calling and executing the firmware program. However, in a multi-processor system, the hot-swap requirement is high and cannot affect the current execution service, so the current execution of the processor cannot be interrupted for too long. In the prior art, the processor invoking and executing the firmware program execution device hot swap operation is sliced and switched into multiple slice executions. Each time the processor receives an interrupt request, it performs a slice operation. After performing a fragmentation operation, the current execution progress is saved and the interrupt is exited. At this time, the processor can resume the current execution service, and is controlled by the timer. After reaching the preset time, the processor sends an interrupt request to the processor. Then the current execution service is interrupted again, and the firmware program is continuously called to perform the operation of the next fragmentation, so that the operation of the hot plugging of the device is completed.

detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

One of the main ideas of the present application may include:

When the first processor receives the device hot plug first interrupt request, responding to the hot plugging of the first interrupt request by the device, by calling and executing the firmware program, generating a device hot plug second interrupt request is sent to the idle processor, idle The processor responds to the device hot plugging the second interrupt request, and implements hot swap operation of the device by calling and executing the firmware program. The hot swap operation of the device is performed by the idle processor. Therefore, the current execution of the service by the first processor does not need to be repeatedly interrupted, the service execution efficiency is ensured, the operating efficiency of the processor is improved, and the idle processor currently has no service execution, so the execution thereof is performed. The hot swap operation of the device does not need to be interrupted repeatedly, so the efficiency of the processor is ensured, and the execution efficiency of the hot swap of the device is ensured.

FIG. 1 is a flowchart of an embodiment of a device resource control method according to an embodiment of the present disclosure The technical solution of the embodiment of the present application is specifically applied to a multi-processor system. The multi-processor system includes two or more processors with similar functions, and the processors can exchange data with each other, and all processors share memory, I/. O device, controller, and external device resources, the entire multiprocessor system is controlled by a unified operating system, and the multiprocessor system includes a first processor.

The method can include the following steps:

Step 101: The first processor, in response to the device hot plugging the first interrupt request, receives the device hot plug first interrupt request.

When a device hot swap operation is required, the interrupt generation can be triggered by a hardware structure such as a south bridge hardware chip.

In a multiprocessor system, each processor can receive an interrupt request, and each processor can select whether to process an interrupt request according to its own operation.

Therefore, the first processor is a processor in the multi-processing system that can process the device to hot plug the first interrupt request.

The first processor is a main processor that processes the device hot swap.

When receiving the hot interrupt first interrupt request, the first processor responds to the first interrupt request, that is, interrupts the current execution service, and performs interrupt processing.

The first processor performs interrupt processing, and other processors may also enter the interrupt until the first processor exits the interrupt processing.

Hot swapping refers to allowing users to remove and replace damaged devices without shutting down the system and cutting off the power, thus improving the system's ability to recover disasters in a timely manner, scalability, and flexibility. When the device is hot swapped, the system needs to add or remove the device to control the device resources.

In this embodiment, the types of hot plug mainly include heat addition and heat removal.

102: The first processor invokes and executes the firmware program, generates a device hot plug second interrupt request, and sends the device hot plug second interrupt request to the idle processor.

The second interrupt request is used to trigger the idle processor to invoke and execute the firmware program, and perform an operation of hot plugging of the device, where the idle processor is currently not processed in the multiprocessor system. Device.

In this embodiment, when the first processor performs the interrupt processing, the firmware program is called. The first processor, by executing the firmware program, triggers the first processor to generate a second device hot plug second interrupt request, and sends the device hot plug second interrupt request to the idle processor. First processor After the idle processor sends the device hot swap second interrupt request, it will exit the current interrupt processing and resume the current execution service.

After receiving the hot plug second interrupt request, the idle processor responds to the hot swapping of the second interrupt request by the device, and performs a hot swap operation by calling and executing the firmware program.

The hot swap operation of the device executed by the idle processor includes the device power-on initialization or device power-off.

The firmware program refers to the program code that is solidified inside the integrated circuit, and is responsible for controlling and coordinating the functions of the integrated circuit, such as a BIOS (Basic Input Output System) program, which is a program that is solidified onto a chip on the main board of the computer. It includes an interrupt handler for handling device hot plug interrupt requests.

In the embodiment of the present application, the type of the interrupt triggered by the hot plugging of the first interrupt request may be a PMI (Platform Management Interrupt) or an SMI (System Management Interrupt), and the device is hot plugged. The type of interrupt triggered by the second interrupt request may be IPI (Inter-Processor Interrupt).

In this embodiment, when the first processor responds to the hot plugging of the first interrupt request by the device, the firmware program is invoked and executed. At this time, the hot swap operation of the device is not performed by the first processor, but the device is hot swapped. The second interrupt request is sent to the idle processor. The idle processor responds to the hot plugging of the second interrupt request by the idle processor to perform a hot swap operation of the device, and the first processor exits the interrupt processing, and the interrupted execution service can be resumed. Since the device hot plug operation is performed by the idle processor, the first processor currently performs the service without being repeatedly interrupted, thereby improving the processor operating efficiency.

The idle processor has no service execution and does not affect the operating efficiency of the entire system, so it can also improve the efficiency of the entire system.

Because the idle processor has no service execution, the hot swap operation of the device can be performed at one time, and the device does not need to be repeatedly interrupted, thereby ensuring the execution efficiency of the device hot swap.

2 is a flowchart of another embodiment of a device resource control method according to an embodiment of the present application. The technical solution of the embodiment of the present application is specifically applied to a multi-processor system, where the multi-processor system includes a first processor, and the method is The following steps can be included:

201: When the first processor receives the device hot plug first interrupt request, responding to the device hot plugging the first interrupt request.

In this embodiment, in order to facilitate the triggering and monitoring of hot swapping of the device, The board management controller sends a device hot plug first interrupt request to the first processor. The device hot plugging first interrupt request may be generated after the baseboard manager or the service manager receives the device hot plug request.

The Baseboard Management Controller (BMC) is a microcontroller on a computer motherboard, and may also be called a Service Processor (SP). The baseboard manager is independent of the operating system and can monitor the hardware status of the multiprocessor system at any time.

The substrate management controller generally includes an operation interface, and the user can trigger the hot plug operation of the device through the operation interface, and control the operation, and the operation is strong, thereby realizing visual monitoring.

Of course, the hot swapping of the first interrupt request of the device may also be triggered by a user operating a button on the motherboard or a button on the chassis, through a hardware structure such as a south bridge hardware chip.

202: The first processor invokes and executes a firmware program to generate a processor offline interrupt request.

The processor offline interrupt request is used to trigger the first processor or the second processor to take any processor that does not include itself as an idle processor.

The first processor or the second processor is a processor in the multiprocessor system capable of processing a processor offline interrupt request. The processor that does not include any processor offline is used as an idle processor. Specifically, the processor that does not include itself and the service processing pressure is relatively small is taken as an idle processor.

The processor offline interrupt request is processed by any processor of the multiprocessor system capable of processing the processor offline interrupt request, and the processor capable of processing the processor offline interrupt request may be the first processor or the multiprocessor The processor is not included in the system, and is defined as a second processor in the embodiment of the present application.

The offline line refers to the service migration. If any processor is offline, the service of any processor is migrated, and the processor can be migrated to another processor or device for execution, so that the processor is in an idle state in which the service is not executed. That is, as an idle processor.

The type of the interrupt triggered by the processor offline interrupt request may be SCI (System Configuration Interrupt).

203: The first processor, when detecting that the idle processor is offline, generates a device hot plug second interrupt request, and sends the device hot plug second interrupt request to the idle processor.

When the idle processor is offline, the device generates a hot swap second interrupt request and sends it to the idle processor. At this time, the first processor exits the current interrupt processing, and when the device receives the hot plug first interrupt request, the breakpoint of the currently executed service continues to be executed.

The first processor generates a processor offline interrupt request, and generates a device hot swap second interrupt request, which can be understood as a process in which the first processor performs a nested interrupt. That is, the first processor responds to the device hot plugging the first interrupt request, that is, calls the firmware program, and generates a processor offline interrupt request by executing the firmware program. At this time, if the interrupt is generated, the first processor can process the processor. The line interrupt request suspends the processing device hot swap interrupt request, and the processing processor offline interrupt request does not include any processor of its own offline, after which the first processor exits the processor offline interrupt request. The interrupt processing continues the interrupt processing of the device hot swap interrupt request, thereby generating a device hot swap second interrupt request.

Of course, the first processor can also send the processor offline interrupt request to the second processor that can process the processor offline interrupt request for processing.

The processing of the processor offline interrupt request is performed by the operating system control processor of the multiprocessor system.

When the first processor or the second processor uses any processor that does not include its own processor as the idle processor, it may first determine whether the current execution service meets the preset condition to determine whether the current execution service is not busy, when the current execution is performed. When the business is not busy, choose any processor to go offline.

The idle processor receives the device hot plug second interrupt request, responds to the device hot plugging the second interrupt request, invokes and executes the firmware program, and implements hot swap operation of the device. The idle processor has no other service execution, so the hot swap operation of the device does not need to be interrupted repeatedly.

The hot swap operation of the device performed by the idle processor includes the device power-on initialization or device power-off operation, which is determined according to the hot plug type.

When the hot-swap type is hot-removed, when the idle processor performs the hot-swap operation of the device, you need to ensure that the device is offline and the services in the device are migrated. The device offline can be executed by the first processor or any processor, and will not be described again in the same way as the prior art.

When the hot-swap type is hot-added, when the device is hot-swapped, the device needs to be powered on, that is, the device is added to the device resource. The device can be online by the first processor or any processor. The same technology will not be described again.

When the idle processor performs hot swap operation of the device, the device may also send a hot swap third interrupt request to the first processor.

The first processor, in response to the device hot plugging the third interrupt request, invoking and executing the firmware program, can generate a processor online interrupt request. The processor uplink interrupt request is used to trigger the first processor or the third processor to bring the idle processor online.

The first processor or the third processor is a processor in the multiprocessor system capable of processing the processor's online interrupt request.

The processor online interrupt request is processed by any processor of the multiprocessor system capable of processing the processor offline interrupt request, and the processor capable of processing the processor online interrupt request may be the first processor or the multiprocessor system. The processor is not included in the first processor. For the convenience of description, the embodiment of the present application is defined as a third processor.

The third processor and the second processor may be the same processor or different processors.

The type of the interrupt triggered by the device hot plugging the first interrupt request may be PMI or SMI.

The type of interrupt triggered by the processor's offline interrupt request can be SCI.

Certainly, the operation of the first processor to invoke and execute the firmware program may further include determining whether the hot plug operation of the device is successfully executed, and the like, and identifying the user to notify the user. For example, it is marked by the on/off of the diode on the main board or the chassis.

In this embodiment, when the first processor responds to the hot plugging of the first interrupt request, the processor may generate a processor offline interrupt request, and trigger any processor that does not include the first processor to be an idle processor. Therefore, when the first processor generates the device hot plugging second request by executing the firmware program, the device hot plugging second request may be sent to the idle processor, because the device hot plug operation is performed by the idle processor, The current execution of a processor by a processor does not need to be repeatedly interrupted, thereby improving the efficiency of the processor.

Since the idle processor has no service execution and avoids the interrupt processing error, the processor is interrupted and cannot be exited, and the interrupt service is suspended indefinitely.

FIG. 3 is a flowchart of still another embodiment of a device resource control method according to an embodiment of the present application. The technical solution of the embodiment of the present application is specifically applied to a multi-processor system, where the multi-processor system includes a first processor, and the method The following steps can be included:

301: The first processor receives a processor offline interrupt request sent by the baseboard management controller.

The substrate management controller can be used to visually monitor the device resource configuration process.

302: The first processor responds to the processor offline interrupt request and will not include any of its own The processor is offline as an idle processor.

The first processor responds to the processor offline interrupt request and performs an interrupt handler such that any processor that does not include itself is taken offline as an idle processor.

In this embodiment, the first processor can process the processor offline interrupt request as an example. In an actual application, the first processor may not process the processor offline interrupt request due to the current running condition. Interrupt processing is performed by any processor that can handle the processor's offline interrupt request.

302: The first processor receives the device hot plug first interrupt request sent by the baseboard management controller, and responds to the device hot plugging the first interrupt request.

As a possible implementation, when the first processor responds to the processor offline interrupt request, it may determine whether the current execution service meets a preset condition to determine whether the current execution service is not busy, when the current execution service is not busy, Take any processor that does not include itself as an idle processor.

The baseboard management controller can monitor the processing result of the processor offline interrupt request, and when the idle processor is offline, send the device hot plug first interrupt request to the first processor.

304: The first processor invokes and executes the firmware program, generates a device hot plug second interrupt request, and sends the device hot plug second interrupt request to the idle processor.

The device hot plugging a second interrupt request is used to trigger the idle processor to perform a hot swap operation of the device.

When the idle processor performs the hot plug operation of the device, the device may be hot swapped for the third interrupt request to the first processor.

The first processor responds to the hot plugging of the third interrupt request by the device, invokes and executes the firmware program, and can detect the hot plug execution result of the device, determine whether the hot plug operation is successful, and identify.

The substrate management controller may obtain the hot plug execution result of the device identified by the first processor, and output prompt information through the visual interface to notify the user.

At the same time, when the baseboard management controller detects the hot plug execution result of the device, or does not detect the hot plug execution result of the device within a preset time, the processor online interrupt request may be generated. The idle processor is brought online by the first processor or the third processor.

In this embodiment, the baseboard management controller may first generate a processor offline interrupt request, trigger the first processor to take any processor offline as an idle processor, and then generate a device hot plug first interrupt request. The first processor is in response to the device hot plugging the first interrupt request, and the firmware program is invoked and executed as an interrupt handler of the device hot plugging the first interrupt request, thereby causing the first processor to generate the device hot swap second interrupt The request is sent to the idle processor, and the idle processor calls and executes the firmware program to implement hot swap operation of the device. Since the device hot plug operation is performed by the idle processor, the current execution of the processor does not need to be repeatedly interrupted, thereby improving the operating efficiency of the processor. Moreover, the hot swap operation of the device can be controlled by the baseboard management controller, which facilitates the monitoring of the processing flow and enables visual monitoring.

The technical solution of the embodiment of the present application is specifically applied to a multi-processor system, where the multi-processor system includes a first processor, and the method The following steps can be included:

401: The first processor, when receiving the device hot plug first interrupt request, responds to the device hot plugging the first interrupt request.

The device hot plug first interrupt request may be generated by the baseboard management controller.

The first processor is a processor in the multi-processing system that can process the device to hot plug the first interrupt request.

402: The first processor calls and executes the firmware program.

403: The first processor generates a device offline interrupt request when determining that the hot plug type is hot removal.

The device offline interrupt request is used to trigger the first processor or the fourth processor to bring the device offline.

The first processor or the fourth processor is a processor in the multiprocessor system capable of processing the device offline interrupt request.

The device offline interrupt request is processed by any processor in the multiprocessor system capable of being requested to go offline. The processor capable of processing the processor offline interrupt request may be the first processor or the multiprocessor system. Does not include any processor of the first processor, in order to The description is convenient, and is defined as a fourth processor in the embodiment of the present application.

The fourth processor and the third processor or the second processor may be the same processor or different processors.
