Description
Technical Field
The present disclosure relates to the field of computer technologies, and in particular, to a method and an apparatus for executing a task of a baseboard management control chip, an electronic device, and a readable storage medium.
Background
The baseboard management control chip is used for monitoring the states of the server, such as temperature, a fan and a Central Processing Unit (CPU), and transmitting video information of the local server to a remote end through a network for remote display and monitoring.
In the related art, the communication mode between the EMAC (Ethernet Media Access Control, network card) in the baseboard management Control chip and the CPU is as follows: first, the CPU of the bmc writes Data to be transmitted by the EMAC into a specified location of a DDR (Double Data Rate) memory, and then transmits the constructed transmission descriptor to the specified location of the DDR. The EMAC analyzes the acquired sending descriptor so as to obtain the target address of the sending data in the DDR and the number of Bytes to be sent. And reading corresponding sending data based on the target address, packaging the data packet through the inside of the EMAC, converting the data packet into a packet format of an Ethernet protocol, and sending the data packet to the network through a physical layer (PHY). In the whole process, the EMAC may frequently communicate with the CPU in an interrupt manner, such as completion of transmission of the current data packet, error checking of the current data packet, error transmission of the current data packet, and the like.

Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and claims of this application and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may include other steps or elements not expressly listed.
Having described the technical solutions of the embodiments of the present invention, various non-limiting embodiments of the present application are described in detail below.
Referring to fig. 1, fig. 1 is a schematic flowchart of a task execution method of a baseboard management control chip according to an embodiment of the present invention, and the method is applied to a CPU of the baseboard management control chip, and the embodiment of the present invention may include the following contents:
s101: and if a task request instruction containing the first identification information is received, setting the driving of the target peripheral equipment required by executing the task request instruction into a polling mode, and simultaneously sending an interface starting and task executing instruction.
S102: and if a task request instruction containing the second identification information is received, setting the driving of the target peripheral equipment into an interrupt mode, and simultaneously sending an interface closing and stopping task execution instruction.
In this embodiment, the first identification information and the second identification information are different identification information, and the first identification information is used to identify that the target peripheral device is in an active state, that is, because the target peripheral device that is relied on to execute the task may communicate with the CPU of the bmc frequently, for example, the CPU may feed back that the sending of the current data packet is completed, the verification of the current data packet is incorrect, and the transmission of the current data packet is incorrect. The second identification information is used to identify that the target peripheral is in a relaxed state, i.e., that the target peripheral has less communication with the CPU of the baseboard management controller after stopping the task being executed. The task request instruction of the present embodiment may be an instruction for executing any task, and is a generic term and is not specific. That is, the task request command of S101 and the task request command of S102 correspond to different executed tasks, for example, the task request command of S101 is to execute a data compression task, and the task request command of S102 is to stop the data compression task. The interface of this embodiment refers to an interface that needs to perform data transmission when executing a task corresponding to the task request instruction, where the task execution instruction and the task stop instruction are issued to the function module that executes the task, and similarly, the start instruction and the close instruction of the interface may also be issued to the function module that executes the task.
It will be appreciated that interrupt mode is a mode of passive handling by the CPU, i.e. the CPU does not know when to interrupt, and will be notified whenever there is an interrupt, and the CPU must now stop the task being executed to handle the interrupt. Polling is the process of active inquiry and processing by the CPU, and the CPU inquires whether the peripheral has tasks to be executed according to a fixed frequency or period. The interruption can miss some data, the missing-prevention mechanism is realized by hardware or software at an upper layer, the polling is efficient without interruption, a temporary storage mechanism is required to be introduced, namely, a CPU cannot just need to process tasks when inquiring the hardware every time, the incoming requests at any time must be temporarily stored in a private area in order to avoid the request missing, and the polling cannot cause the request missing as long as the requests are made. Because only one CPU is provided, only one request can be processed at the same time point, and a large amount of omission and competition can be caused when a plurality of interrupts are triggered at high frequency. Polling is not missed because it is requested by the CPU batch-and-packet processing. However, polling is preferred at times when interrupts are too frequent, which may result in the CPU not having time to perform other tasks for the host, since the CPU must handle the interrupts. If the peripheral activity is very mild, polling is not appropriate and the scenario is suitable for interrupts. Based on this, the application identifies whether the peripheral is in an active state or a moderate state through the first identification information and the second identification information, and then determines whether the communication between the CPU and the peripheral is in a polling mode or an interruption mode, which is beneficial to improving the working efficiency of the CPU.
In the technical scheme provided by the embodiment of the invention, the communication mode between the CPU of the substrate management control chip and the peripheral is determined according to whether the task needs to be executed, namely whether the peripheral is in an active state or a moderate state, the data packet is long and frequent when the task is executed, the CPU of the substrate management control chip actively adopts a polling mode to interact with the peripheral, the data packet is short and sparse when the task is not required to be executed, and the CPU of the substrate management control chip actively adopts an interruption mode to communicate with the peripheral, so that the working efficiency of the CPU of the substrate management control chip can be effectively improved, the frequent interruption of the CPU is avoided, the problem that the performance of the CPU for executing system tasks and receiving other state information of a host end is reduced in the related technology is solved, and the normal operation of the system tasks operated on the CPU can be ensured.
It is understood that in the whole process of executing a certain kind of task, there may be 1 external device on which the task is executed, but occasionally the associated device is used, for example, when executing a data access task, an external device such as a mouse is mainly used to complete, but in some scenarios, a keyboard is used, so the keyboard and the mouse belong to the associated device. In order to further improve the working efficiency of the CPU of the bmc chip, based on the above embodiment, the method may further include:
acquiring associated peripheral equipment associated with the target peripheral equipment;
after the driver of the target peripheral required by the task request instruction is set to be in a polling mode, the driver of the associated peripheral equipment can be set to be in the polling mode, so that the CPU of the baseboard management control chip communicates with the target peripheral and the associated peripheral equipment in the polling mode.
After the drive of the target peripheral equipment is set to be the interrupt mode, the drive of the associated peripheral equipment can be set to be the interrupt mode, so that the CPU of the substrate management control chip is communicated with the target peripheral equipment and the associated peripheral equipment in the interrupt mode.
In this embodiment, the associated peripheral device is an external device that needs to be used or may be used in the process of executing the task corresponding to the task request instruction, and a person skilled in the art can determine the associated peripheral device of the target peripheral device according to an actual application scenario. In order to further improve the setting efficiency of the associated peripheral equipment, a file for storing the associated peripheral equipment can be preset, and the system can obtain the associated peripheral equipment associated with the current target peripheral equipment by inquiring the file.
In order to make the technical solutions of the present application more obvious to those skilled in the art, the present application also describes the technical solutions of the present application in conjunction with fig. 2 and fig. 3 by taking the video monitoring task as an illustrative example, which may include the following:
in the related art, a scheme for transmitting a compressed video in a bmc is shown in fig. 2, where HOST is a HOST side, cmp (compression) is a device for controlling video compression in the bmc, and may be referred to as a compressed video controller, EMAC is a network card, and DDR is an off-chip memory, and a specific compressed video flow is as follows:
1: the video information of HOST is passed to the CMP of the bmc chip.
2: the information of the HOST, such as the temperature information of the HOST CPU, the fan speed information, the power supply voltage information, etc., is transmitted to the bmc chip.
3: the compressed video information is written to the off-chip DDR.
4: and the EMAC driver running on the CPU packs the compressed video information and running state information of the HOST end layer by layer into a data format of a network layer according to the requirement of a TCP/IP protocol and writes the data format into the DDR.
5: and reading the data packet to be sent back to the interior of the EMAC by the EMAC, and packaging and the like. The data packet to be sent is in a network layer data format.
6: the EMAC is frequently communicated with the baseboard management control chip in an interruption mode in the process of receiving and sending data packets.
7: the EMAC packed data in the data link layer format is sent through the physical layer PHY and the network, and meanwhile, the network data packet of the opposite end passing through the PHY and then the network is received, and the receiving process is also frequently communicated with the baseboard management control chip in an interruption mode.
Video data of a HOST display card is generated continuously, when video information with huge data volume is sent through a network, interrupt resources of a baseboard management control chip are occupied frequently, a CPU can turn to execute an interrupt service subprogram, so that the efficiency of processing system tasks of the CPU is lowered, the real-time state of a local HOST end cannot be timely transmitted to a remote end, meanwhile, a remote monitoring management end needs to manage the state of the local HOST, namely the server end, for example, the rotating speed of a fan is changed, or firmware updating of the baseboard management control chip is updated, and the management instruction of the HOST end cannot be executed quickly. When some emergency situations of the HOST end face and the remote end is urgently needed to process, serious influence can be caused, and stable and reliable operation of the HOST is not facilitated.
In order to solve the drawbacks of the prior art, the communication mode between the EMAC and the baseboard management control chip of the present application includes two modes, namely interrupt and polling. When the network data packet is long and frequent, the CPU of the baseboard management control chip actively adopts a polling mode to interact with the EMAC, and when the network data packet is short and sparse, the CPU of the baseboard management control chip actively adopts an interruption mode.
The task request instruction is a video monitoring instruction sent by the remote client, when the analyzed video monitoring instruction contains a first network data packet, the network card drive is set to be in a polling mode, and meanwhile, an instruction for starting a video data receiving interface and executing a video data compression task is sent to the compressed video controller. And when the video monitoring instruction sent by the remote analysis client side contains a second network data packet, setting the network card drive to be in an interrupt mode, and simultaneously sending an instruction for closing the video data receiving interface and stopping a video data compression task to the compressed video controller.
Based on the above prior art, in order to implement the technical solution of the present application, the present application modifies the monitoring management software running at the remote end and the monitoring management software running locally at the host end, as shown in fig. 3, step 8 is control information sent to the CMP by the local monitoring management software according to the received network data packet with the remote video function turned on/off. Specifically, the method comprises the following steps:
when a monitor needs to perform video monitoring on the local HOST, the monitoring management software running at the remote end needs to send a specific network data packet to the baseboard management control chip. When the network data packet agreed in the above steps is detected, the settings made by the local monitoring management software of the host end include: firstly, a network card drive, namely an EMAC drive, operated by the CPU is set to be a polling mode, so that a large amount of video data are transmitted at the moment, if a traditional interruption mode is used, the CPU is interrupted frequently, and the performance of the CPU for executing system tasks and receiving other state information of a host end is further reduced. The CMP starts the interface that receives the HOST raw video data and starts video compression. When the remote end closes the video monitoring function, a specific network format packet is also sent, and the packet is different from the data packet in the step 1. When the network data packet agreed in the above steps is detected, the settings made by the local monitoring management software of the host end include: firstly, a network card drive operated by a CPU is set to be an interrupt mode, and the interrupt mode can be used for more quickly executing HOST end state information and transmitting the HOST end state information through an EMAC network. The CMP closes the interface receiving the HOST raw video data and stops video compression. Also, network packets without video data are sent through the EMAC and an interrupt is generated.
In this embodiment, when the remote end starts the video monitoring function, because the video data is continuously generated, and the network data packet is very frequent, the remote monitoring end actively informs the local CPU and the driver through the specific network data packet, and the driver analyzes the received specific data packet to know that the remote end needs to perform video monitoring, and at this time, the CPU needs to communicate with the EMAC in a polling manner. Of course, other peripherals whose interaction frequency with the CPU is low are still an interrupted way. Furthermore, the CPU can be prevented from being in an interrupted state for a long time/high frequency to delay normal system task execution, the CPU can not be interrupted by the EMAC for a long time, and real-time state information collection of a local HOST end is facilitated. And when the remote end does not start the video monitoring function, the baseboard management control chip stops receiving the video data, and the EMAC waits for the interrupt information of the EMAC and other peripheral equipment in an interrupt mode. Based on the foregoing embodiment, the transmission process of the compressed video in this embodiment may include:
a1: when the video monitoring function of the remote end is detected to be started, the video information of the HOST HOST is transmitted to the CMP of the substrate management control chip.
A2: the information of the HOST, such as the temperature information of the HOST CPU, the fan speed information, the power supply voltage information, etc., is transmitted to the bmc chip.
A3: the compressed video information is written to the off-chip DDR.
A4: and the EMAC driver running on the CPU packs the compressed video information and running state information of the HOST end layer by layer into a data format of a network layer according to the requirement of a TCP/IP protocol and writes the data format into the DDR memory.
A5: and reading the data packet to be sent back to the interior of the EMAC from the DDR by the EMAC, and performing packaging and other processing. The data packet to be sent is in a network layer data format.
A6: the EMAC is frequently communicated with the baseboard management control chip in a polling mode in the process of receiving and sending data packets.
A7: and transmitting the data in the data link layer format after EMAC packaging through a physical layer (PHY) and a network, and receiving a network data packet which passes through the PHY and then the network from an opposite end.
In this embodiment, for a6 and a7, according to a preset query frequency, actively querying and processing an instruction sent by a network card in the process of reading a data packet to be sent from a memory and sending a packaged data packet to a remote client. In the whole process, after detecting that the video monitoring function is started, the CPU sends an instruction for starting a video data receiving interface and executing a video data compression task to the CMP.
As can be seen from the above, in this embodiment, the communication mode between the EMAC and the CPU is optimized from the conventional interrupt-only mode to the combined mode of interrupt plus polling. According to whether video transmission is required or not, the communication mode of the CPU and the EMAC is further determined, so that accurate and efficient selection between interruption and polling can be guaranteed. The normal execution of system tasks and the normal transmission of other HOST states are ensured in the process of transmitting video data.
It should be noted that, in the present application, there is no strict sequential execution order among the steps, and as long as a logical order is met, the steps may be executed simultaneously or according to a certain preset order, and fig. 1 to fig. 3 are only schematic manners, and do not represent only such an execution order.
