In the related art, the communication mode between EMAC (ETHERNET MEDIA ACCESS Control, network card) and CPU in the baseboard management Control chip is: first, the CPU of the baseboard management control chip writes Data to be transmitted through EMAC to a specified location of a memory DDR (Double Data Rate), and then transmits the constructed transmission descriptor to the specified location of the DDR. The EMAC parses the acquired transmit descriptor to obtain the target address of the transmit data in the DDR and the number of Bytes to be transmitted.

Detailed Description
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims and drawings are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. 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 embodiments of the present application, various non-limiting embodiments of the present application are described in detail below.
Referring first to fig. 1, fig. 1 is a flow chart of a task execution method of a baseboard management control chip provided by an embodiment of the present invention, which is applied to a CPU of the baseboard management control chip, and the embodiment of the present invention may include the following:
s101: if a task request instruction containing first identification information is received, setting a drive of a target peripheral required for executing the task request instruction as a polling mode, and simultaneously sending an interface starting and task executing instruction.
S102: if a task request instruction containing second identification information is received, setting the driving of the target peripheral equipment to be in an interrupt mode, and simultaneously sending an instruction for closing the interface and stopping task execution.
In this embodiment, the first identification information and the second identification information are different identification information, where the first identification information is used to identify that the target peripheral is in an active state, that is, because the target peripheral that depends on executing the task may communicate with the CPU of the baseboard management controller frequently, for example, feedback to the CPU that the current data packet is sent completely, the current data packet checks for errors, the current data packet transmits for errors, and so on. The second identification information is used to identify that the target peripheral is in a relaxed state, i.e. that there is less communication between the target peripheral and the CPU of the baseboard management controller due to stopping the task being performed. The task request instruction of the present embodiment may be an instruction for executing any task, and is a generic term, not a specific term. That is, the task request instruction of S101 and the task request instruction of S102 are not the same task to be executed, for example, the task request instruction of S101 is to execute a data compression task, and the task request instruction of S102 is to stop a data compression task. The interface in this embodiment is an interface that needs to perform data transmission when executing a task corresponding to a task request instruction, where a task execution instruction and a task stopping instruction are issued to a functional module that executes a task, and similarly, an opening instruction and a closing instruction of the interface may also be issued to the functional module that executes a task.
It will be appreciated that the interrupt mode is one of the ways that the CPU passively processes, that is, the CPU does not know when an interrupt is made, and the CPU is notified whenever there is an interrupt, and the CPU must stop the executing task at this time to process the interrupt. Polling is the process that the CPU actively queries and processes, and the CPU queries whether the peripheral has tasks to execute according to a fixed frequency or period. Interrupts miss some data, the mechanism to avoid the miss is realized by hardware or upper software, while polling is not efficient, and a temporary storage mechanism must be introduced, that is, since the CPU cannot just need to process tasks when querying the hardware each time, in order not to miss a request, the request coming at any time must be temporarily stored in a private area, so long as all the requests are done, and polling does not cause the request to miss. Since there is only one CPU, only one request can be processed at the same time point, and the interrupt can cause a large number of omission and competition when many interrupts are triggered at high frequency. The polling is not missed because it is a CPU batch packing processing request. However, since the CPU must handle interrupts, interrupts too often may cause the CPU to have no time to perform other tasks of the host, which is preferable. If the peripheral activity is very gentle, polling is not appropriate and the scenario is applicable to interrupts. Based on the method, the peripheral is identified to be in an active state or a relaxed state through the first identification information and the second identification information, so that whether the communication between the CPU and the peripheral adopts a polling mode or an interrupt mode is determined, and the working efficiency of the CPU is improved.
In the technical scheme provided by the embodiment of the invention, the communication mode between the CPU of the baseboard management control chip and the peripheral is determined according to whether the task is to be executed, namely, whether the peripheral is in an active state or a relaxed state, the data packet is long and frequent when the task is executed, the CPU of the baseboard 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, the CPU of the baseboard management control chip actively adopts an interrupt mode to communicate with the peripheral, the working efficiency of the CPU of the baseboard management control chip can be effectively improved, the problem that the CPU is frequently interrupted is solved, and the defect that the performance of the CPU for executing system tasks and receiving other state information of a host side is reduced in the prior art is solved, and the normal operation of the system tasks running on the CPU can be ensured.
It will be appreciated that there may be mainly 1 external device on which a task is performed during the whole process of performing a certain type of task, but the associated device may be used occasionally, for example, when performing a data access task, this is mainly done based on a mouse, but in some cases a keyboard is used, so that the keyboard and the mouse belong to the associated device. In order to further improve the working efficiency of the CPU of the baseboard management control chip, based on the above embodiment, the method may further include:
acquiring associated peripheral equipment of a target peripheral;
After the drive of the target peripheral required for executing the task request instruction is set to the polling mode, the drive of the associated peripheral may also be set to the polling mode, so that the CPU of the baseboard management control chip communicates with the target peripheral and the associated peripheral in the polling mode.
After the driving of the target peripheral is set to the interrupt mode, the driving of the associated peripheral device may also be set to the interrupt mode, so that the CPU of the baseboard management control chip communicates with the target peripheral and the associated peripheral device in the interrupt mode.
In this embodiment, the associated peripheral device is an external device that needs to be or possibly needs to be used in the task process corresponding to the task request instruction, and the person skilled in the art can determine the associated peripheral device of the target peripheral device according to the actual application scenario. In order to further improve the setting efficiency of the associated peripheral device, a file for storing the associated peripheral device may be preset, and the system may obtain the associated peripheral device associated with the current target peripheral device by querying the file.
In order to make the technical solution of the present application more clear for those skilled in the art, the present application is further described with reference to fig. 2 and 3 to perform video monitoring tasks as an illustrative example, and may include the following:
In the related art, as shown in fig. 2, a scheme for transmitting compressed video in a baseboard management controller is shown in fig. 2, HOST is a HOST, CMP (compression) is a device for controlling video compression in the baseboard management controller, which may be called a compressed video controller, EMAC is a network card, DDR is an off-chip memory, and a specific compressed video flow is as follows:
1: the video information of HOST is transferred to CMP of the baseboard management control chip.
2: The operation state information of the HOST HOST, such as temperature information of the HOST CPU, fan rotation speed information, power supply voltage information, etc., is transmitted to the baseboard management control 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 the running state information thereof at the HOST end layer by layer into a data format of a network layer according to the requirements of a TCP/IP protocol and writes the data format into the DDR.
5: The EMAC reads the data packet to be sent back to the interior of the EMAC for packaging and packaging. The data packet to be transmitted is in the network layer data format.
6: The EMAC frequently communicates with the baseboard management control chip in an interrupt manner during the process of receiving and transmitting the data packet.
7: The data in the data link layer format after the EMAC package is completed is firstly transmitted through the physical layer PHY and the network, and meanwhile, the receiving opposite end receives the network data packet through the PHY and then the network, and the receiving process is also frequently communicated with the baseboard management control chip in an interrupt mode.
The video data of the HOST video card is continuously generated, when the video information with huge data volume is sent through a network, the interrupt resource of the baseboard management control chip is frequently occupied, the CPU can turn to execute an interrupt service subroutine, so that the efficiency of the processing system task of the CPU is low, the real-time state of the local HOST end is not timely transmitted to the remote end, meanwhile, the remote monitoring management end needs to perform state management on the local HOST, namely the server end, such as changing the rotating speed of a fan, or updating the firmware of the baseboard management control chip, and the management instruction of the HOST end cannot be rapidly executed. In the face of some emergency situations of HOST end, when the remote end is required 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 of the EMAC and the baseboard management control chip of the present application includes two modes of 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 actively adopts an interrupt mode.
The task request instruction is a video monitoring instruction sent by the remote client, and when the video monitoring instruction is analyzed to contain 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. When the video monitoring instruction sent by the remote client is analyzed to contain a second network data packet, the network card driver is set to be in an interrupt mode, and meanwhile, an instruction for closing the video data receiving interface and stopping the video data compression task is sent 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 by the local monitoring management software to the CMP after the local monitoring management software turns on/off the network data packet of the video function according to the received remote. Specific:
When a monitor needs to perform video monitoring on the local HOST end, the monitoring management software running on the remote end needs to send a specific network data packet to the baseboard management control chip. When detecting the network data packet agreed in the above steps, the setting made by the monitoring management software local to the host side includes: firstly, a network card drive running by a CPU, namely an EMAC drive is set to be in a polling mode, so that a large amount of video data is transmitted at the moment, if a traditional interrupt mode is used, the CPU is frequently interrupted, and further, the performance of the CPU for executing system tasks and receiving other state information of a host end is reduced. The CMP starts the interface for receiving HOST original video data and starts video compression. When the remote end turns off 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 detecting the network data packet agreed in the above steps, the setting made by the monitoring management software local to the host side includes: firstly, the network card driver operated by the CPU is set as an interrupt mode, and the interrupt mode can be used for executing faster network transmission of HOST end state information through the EMAC. The CMP closes the interface receiving HOST original video data and stops video compression. No network packets of video data are sent over 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, 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 obtain 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 with which the CPU interacts very infrequently remain an interrupt. And further, the CPU can be prevented from being in an interrupted state for a long time or at a high frequency to delay the normal system task execution, the CPU is not interrupted by the EMAC for a long time, and the real-time state information collection of the local HOST end is facilitated. And when the remote end does not start the video monitoring function, the baseboard management control chip stops receiving video data, and the EMAC adopts a mode of taking interruption to wait for interruption information of the EMAC and other peripheral equipment. Based on the above embodiments, the transmission process of the compressed video according to the present embodiment may include:
A1: after detecting that the video monitoring function of the remote terminal is started, video information of the HOST HOST is transmitted to the CMP of the baseboard management control chip.
A2: the operation state information of the HOST HOST, such as temperature information of the HOST CPU, fan rotation speed information, power supply voltage information, etc., is transmitted to the baseboard management control 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 the running state information thereof at the HOST end layer by layer into a data format of a network layer according to the requirements of a TCP/IP protocol and writes the data format into a memory DDR.
A5: the EMAC reads the data packet to be sent back to the inside of the EMAC from the DDR for packaging and packaging. The data packet to be transmitted is in the network layer data format.
A6: the EMAC frequently communicates with the baseboard management control chip by polling during the process of receiving and transmitting data packets.
A7: the data in the data link layer format after the EMAC packaging is finished is firstly transmitted through a physical layer PHY and a network, and meanwhile, a network data packet of an opposite terminal through the PHY and then through the network is received.
In this embodiment, for A6 and A7, according to a preset query frequency, the instructions sent by the network card in the process of reading the data packet to be sent from the memory and sending the packaged data packet to the remote client are actively queried and processed. In the whole process, the CPU also sends an instruction for starting a video data receiving interface and executing a video data compression task to the CMP after detecting that the video monitoring function is started.
As can be seen from the above, the communication mode between the EMAC and the CPU of the baseboard management control chip is optimized from the conventional interrupt-only mode to the combined mode of interrupt and polling. According to whether video transmission is required, the communication mode between the CPU and the EMAC is determined, so that accurate and efficient selection between interruption and polling can be ensured. The normal execution of system tasks and the normal transmission of other states of HOST in the process of transmitting video data are ensured.
It should be noted that, in the present application, the steps are not strictly executed sequentially, so long as they conform to the logic sequence, the steps may be executed simultaneously, or may be executed according to a certain preset sequence, and fig. 1-3 are only schematic, and do not represent only such an execution sequence.
