Description

Technical Field

[0002] In a server, when a remote server is remotely managed through a BMC (Baseboard management controller), the remote image can be received from the server, compressed, and then sent to the local computer through the network for image display.

[0003] However, in the baseboard management controller, the DDR (Double Data Rate) controller is shared, and various application services of the baseboard management controller need to occupy the double data rate synchronous dynamic random access memory to run, which usually leads to insufficient bandwidth of the double data rate synchronous dynamic random access memory and image loss of the remote screen. Although the loss of the remote image screen is allowed, it will give users a visual jump feeling of the screen, and it is not possible to monitor and manage the remote server well.

[0004] In summary, how to improve the remote image monitoring capability of the baseboard management controller is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0064] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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.

[0065] See also Figure 1 , Figure 1 A flowchart of a request scheduling method provided by an embodiment of the present invention.

[0066] A request scheduling method provided by an embodiment of the present invention may include the following steps:

[0067] Step S101: obtaining a target request sent by a target object, where the target request is used by the target object to request to apply a double rate synchronous dynamic random access memory in a baseboard management controller.

[0068] In actual applications, when the target object needs to apply the double-rate synchronous dynamic random access memory in the baseboard management controller, it can first send a corresponding target request. Correspondingly, the present invention can obtain the target request sent by the target object and perform subsequent request scheduling based on the target request.

[0069] It should be noted that the target object refers to an object that needs to apply the double rate synchronous dynamic random access memory in the baseboard management controller, and its type can be flexibly determined according to actual needs. For example, the target object can be a business module in the baseboard management controller.

[0070] Step S102: Determine a request number identification pool corresponding to the target object, where the request number identification pool is used to record the request number identification.

[0071] In actual applications, when a target request is triggered, a request number identification pool corresponding to the target object can be determined. This request number identification pool is used to record the request number identification, and the request number identification has two states: valid and invalid. When the request number identification is valid, it indicates that the target object has an opportunity to send a double-rate synchronous dynamic random access memory request to the double-rate synchronous dynamic random access memory controller. When the request number is invalid, it indicates that the target object does not have an opportunity to send a double-rate synchronous dynamic random access memory request to the double-rate synchronous dynamic random access memory controller. The number of request number identifications in the request number identification pool and the validity and invalidity of each request number identification can be flexibly determined according to the application scenario.

[0072] Step S103: Check whether there is a valid target request number identifier in the request number identifier pool.

[0073] Step S104: In response to the existence of a target request number identifier in the request number identifier pool, the target object is allowed to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller, and the target request number identifier in the request number identifier pool is invalidated so that the double rate synchronous dynamic random access memory controller responds to the double rate synchronous dynamic random access memory request.

[0074] Step S105: In response to the target request number identifier not existing in the request number identifier pool, prohibiting the target object from sending a DDRSDRAM request to the DDRSDRAM controller.

[0075] In actual applications, after determining the request number identification pool corresponding to the target object, it is possible to detect whether there is a valid target request number identification in the request number identification pool. In response to the existence of the target request number identification in the request number identification pool, the target object can be allowed to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller, and the target request number identification in the request number identification pool is invalidated to avoid the target object from repeatedly applying the target request number identification to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller. In other words, a single request number identification can only allow the target object to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller once. Accordingly, after the double rate synchronous dynamic random access memory controller responds to the double rate synchronous dynamic random access memory request, the target object can apply the double rate synchronous dynamic random access memory in the baseboard management controller. Similarly, in response to the absence of the target request number identification in the request number identification pool, the target object is prohibited from sending a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller.

[0076] It should be noted that, in the process of allowing the target object to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller or prohibiting the target object from sending a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller, a first message can be sent to the target object to control the target object to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller through the first message, and a second message can be sent to the target object to instruct the target object to prohibit sending a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller through the second message; of course, the target object can also be given permission to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller to allow the target object to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller, or the target object can be given permission to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller to prohibit the target object from sending a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller, etc.

[0077] In actual application, in the process of detecting whether there is a valid target request number identifier in the request number identifier pool, the first identifier pool can be determined in the request number identifier pool; detecting whether there is a valid first request number identifier in the first identifier pool; in response to the existence of the first request number identifier in the first identifier pool, detecting whether there is a corresponding second identifier pool for the first request number identifier; in response to the absence of a corresponding second identifier pool for the first request number identifier, the first request number identifier is used as the target request number identifier. It should be noted that the number of request number identifier pools in the first identifier pool and the number of request number identifier pools in the second identifier pool can be flexibly determined according to the application scenario. For example, the first identifier pool may include 8 request number identifiers, and 4 request number identifiers can be set under these 8 request number identifiers, that is, the second storage pool may include 4 request number identifiers, etc. In addition, in a specific application scenario, after detecting whether there is a valid first request number identifier in the first identifier pool, in response to the absence of a valid first request number identifier in the first identifier pool, it can be determined that there is no target request number identifier in the request number identifier pool.

[0078] From this implementation process, it can be known that the present invention sets the request number identification pool to include a first identification pool and a second identification pool, and the second identification pool is set under the request number identification of the first identification pool. In this way, when the request number identification in the first identification pool is insufficient, the corresponding second identification pool can be opened to increase the number of request number identifications, so as to flexibly control the opportunity of the target object to send a double-speed synchronous dynamic random access memory request to the double-speed synchronous dynamic random access memory controller. It should be noted that the present invention only uses a two-level identification pool to illustrate the request number identification pool. In a specific application scenario, the request number identification pool may include a three-level identification pool, a four-level identification pool, etc., and the present invention does not make specific limitations here.

[0079] It should also be noted that when there are multiple objects, the number of request number identifiers in the first identification pool and the second identification pool of each object can be the same or different, and can be flexibly determined according to the application requirements of the object for the double-speed synchronous dynamic random access memory. For example, if the object has a high application requirement for the double-speed synchronous dynamic random access memory, the number of request number identifiers in the first identification pool and the second identification pool of the object can be set to be larger, and when the numbers are the same, the number of valid request number identifiers can be set to be larger, etc. In addition, the number of request identification numbers in the second storage pool can be understood as how many times the request number identifier in the first identification pool can be applied. Of course, according to this principle, a third identification pool can be set after the request number identifier in the second identification pool, and the number of applications of the request number identifier in the second identification pool is also limited. At this time, the effective detection principle of the request number identifier in the second identification pool is consistent with the detection principle of the request number identifier in the first identification pool.

[0080] In a specific application scenario, the request number identifier in the first identification pool can also be set. For example, the request number identifier in the first identification pool can be set according to the competitive ability of the target object and other objects for the double-rate synchronous dynamic random access memory, that is, within the first time period, the request hit rate of the target object is counted, and the request hit rate of other objects is counted. The first time period can be flexibly determined according to application requirements, and the request hit rate represents the probability of the double-rate synchronous dynamic random access memory request being responded to; in response to the target object having the highest request hit rate, the valid request number identifier in the first identification pool is reduced, and the valid request number identifier in the identification pool of other objects is increased, until the request hit rate of the target object is the same as the request hit rate of other objects. Correspondingly, in response to the target object's request hit rate not being the highest, the valid request number identifier in the first identification pool is increased, and the valid request number identifier in the identification pool of other objects with the highest request hit rate is reduced, until the request hit rate of the target object is the same as the request hit rate of other objects.

[0081] From the implementation process, it can be seen that the present invention counts the request hit rate of the target object and the request hit rate of other objects within the first time period, and uses the request hit rate to characterize the probability that the double-rate synchronous dynamic random access memory request of the object is actually responded to; and the valid request number identifiers in the request number identifier pool with a low request hit rate can be increased, and the valid request number identifiers in the request number identifier pool with a high request hit rate can be reduced, so that the probability that the double-rate synchronous dynamic random access memory request of each object is actually responded to is the same, so that the probability of different objects applying the double-rate synchronous dynamic random access memory can be made the same, which is conducive to balancing the application capabilities of different objects to the double-rate synchronous dynamic random access memory.

[0082] In actual applications, when both the first identification pool and the second identification pool exist, the first identification pool and the second identification pool can be set based on the number of valid request number identifications in the two identification pools. For example, in response to the target object having the highest request hit rate, the valid request number identifications in the second identification pool can be reduced first. When there are no valid request number identifications in the second identification pool, the valid request number identifications in the first identification pool can be reduced again until all request number identifications in the first identification pool are invalid. In response to the target object having the highest request hit rate, the valid request number identifications in the first identification pool can be increased first. After all request number identifications in the first identification pool are valid, the valid request number identifications in the second identification pool can be increased again until all request number identifications in the second identification pool are valid.

[0083] From the implementation process, it can be seen that, when increasing the number of valid request number identifiers in the request number identifier pool of the target object, the present invention first applies the first identifier pool to increase the chance of the target object sending a DDR request. When the first identifier pool is insufficient, the second identifier pool is added to further increase the chance of the target object sending a DDR request. Correspondingly, when reducing the number of valid request number identifiers in the request number identifier pool of the target object, the second identifier pool is first applied to reduce the chance of the target object sending a DDR request. When the second identifier pool is insufficient, the first identifier pool is reduced to further reduce the chance of the target object sending a DDR request. In this way, the chance of the target object sending a DDR request can be fine-grained and accurately controlled based on the first identifier pool and the second identifier pool.

[0084] In a specific application scenario, in the process of counting the request hit rate of the target object, the first number value of the double-rate synchronous dynamic random access memory requests sent by the target object to the double-rate synchronous dynamic random access memory controller can be counted; the number of times the target object obtains control of the double-rate synchronous dynamic random access memory can be counted; and the ratio of the number value to the first number value can be used as the request hit rate of the target object.

[0085] In a specific application scenario, after detecting whether there is a corresponding second identification pool for the first request number identification, in response to the existence of a corresponding second identification pool for the first request number identification, it is necessary to further detect whether there is a valid second request number identification in the second identification pool; in response to the existence of the second request number identification in the second identification pool, the second request number identification is used as the target request number identification. Correspondingly, in response to the absence of a valid second request number identification in the second identification pool, it can be determined that the target request number identification does not exist in the request number identification pool.

[0086] In specific application scenarios, the request number identifier in the second identifier pool can also be set. For example, within the second time period, the second number value of the target request sent by the target object can be counted; whether the second number value is greater than the preset number value can be detected; in response to the second number value being greater than the preset number value, the valid request number identifier in the second identifier pool can be increased. For example, if the number of target requests sent by the target object within one second exceeds 16, the valid request number identifier in the second identifier pool can be increased.

[0087] In practical applications, the user's setting information for the request number identification pool can also be obtained, and the setting information is used to set whether the request number identification in the request number identification pool is valid; determine the real-time validity information of the request number identification in the request number identification pool; perform a bitwise OR operation on the setting information and the real-time validity information to obtain the target validity information of the request number identification in the request number identification pool; wherein the request number identification includes a bit, and when the value of the bit is 1, it indicates that the request number identification is valid, and when the value of the bit is 0, it indicates that the request number identification is invalid. At this time, the relationship between the first identification pool and the second identification pool can be as shown in Table 1 and Table 2, wherein the double rate synchronous dynamic random access memory transmission request modules A, B, and C are different objects.

[0088] Table 1 Schematic table of request number identification of the first identification pool

[0089]

[0090] Table 2 Schematic diagram of request number identification of the second identification pool

[0091]

[0092] It should be noted that the user can set invalid or valid request number identifiers in the request number identifier pool at any time. For example, when the business volume transmitted by the target object to the double-rate synchronous dynamic random access memory increases, the number of valid request number identifiers in the request number identifier pool can be increased, that is, more request number identifier bits can be set to 1; when the business volume decreases, the number of valid request number identifiers in the request number identifier pool can be reduced, that is, the number of invalid request number identifiers in the request number identifier pool can be increased, and more request number identifier bits can be set to 0.

[0093] The present invention provides a request scheduling method, which obtains a target request sent by a target object, the target request is used for the target object to request a double rate synchronous dynamic random access memory in an application baseboard management controller; determines a request number identification pool corresponding to the target object, the request number identification pool is used to record the request number identification; detects whether there is a valid target request number identification in the request number identification pool; in response to the existence of a target request number identification in the request number identification pool, allows the target object to send a double rate synchronous dynamic random access memory request to a double rate synchronous dynamic random access memory controller, and invalidates the target request number identification in the request number identification pool, so that the double rate synchronous dynamic random access memory controller responds to the double rate synchronous dynamic random access memory request; in response to the absence of a target request number identification in the request number identification pool, prohibits the target object from sending a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller. The present invention sets a request number identification pool for each target object, and uses the request number identification pool to store the request number identification corresponding to the target object. Only when the target request number identification in the request number identification pool is valid, the target object is allowed to send a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller of the baseboard management controller to apply the double rate synchronous dynamic random access memory. In this way, the request number identification in the request number identification pool can be set to be valid or not to control the ability of the target object to apply the double rate synchronous dynamic random access memory, so that the process of each object applying the double rate synchronous dynamic random access memory is under control, avoiding the situation that each business in the baseboard management controller uncontrollably seizes the double rate synchronous dynamic random access memory, can improve the bandwidth of the double rate synchronous dynamic random access memory, reduce the image loss of the remote screen, and thus improve the remote screen monitoring capability of the baseboard management controller.

[0113] A request scheduling system provided by an embodiment of the present invention may further include:

[0114] The second setting unit is used to set the request number identifier in the second identifier pool.

[0115] A request scheduling system provided by an embodiment of the present invention, the second setting unit can be used to: count the second number value of target requests sent by the target object within a second time period; detect whether the second number value is greater than a preset number value; in response to the second number value being greater than the preset number value, add a valid request number identifier in the second identifier pool.

[0116] A request scheduling system provided by an embodiment of the present invention may further include:

[0117] A second acquisition module is used to acquire the user's setting information for the request number identification pool, where the setting information is used to set whether the request number identification in the request number identification pool is valid;

[0118] The second determination module is used to determine whether the request number identifier in the request number identifier pool is valid in real time;

[0120] The request number identifier includes a bit. When the value of the bit is 1, it indicates that the request number identifier is valid. When the value of the bit is 0, it indicates that the request number identifier is invalid.

[0121] In order to facilitate understanding of the request scheduling system provided by the present invention, it is now assumed that the number of objects competing for the right to control the double rate synchronous dynamic random access memory is 3, namely, service module A, service module B, and service module C, and the number of bits in the first identification pool of each device is 8 bits. The implementation block diagram of the present invention is as follows: Figure 3 As shown in the figure, only the actual application example of business module C is given, and no specific application examples are given for business module A and business module B. The example function of business module A is as follows Figure 4 As shown, the functions of the local image restoration module are as follows Figure 5 shown.

[0122] The original image data refers to the image screen of the remote server;

[0123] The upper configuration module is used for users to configure the values ​​of the first identification pool and the second identification pool of each module according to needs, and to modify the value of the first identification pool in the coarse-grained probability balance adjustment module and the value of the fine-grained second identification pool in the fine-grained probability balance adjustment module according to user needs;

[0124] The image capture module is used to extract the image data according to the frame header and frame footer of each frame after receiving the image data, and send it to the compression engine module;

[0125] The compression engine is responsible for JPEG compression of image data and provides compressed image data to the output control module;

[0126] The image output control module is responsible for requesting the control right of the double rate synchronous dynamic random access memory controller and storing the compressed image in the double rate synchronous dynamic random access memory storage unit.

[0130] If the transmission request module A receives the double rate synchronous dynamic random access memory transmission request initiated by the business module A, it sends a request to the corresponding fine-grained probability balance adjustment module to initiate a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller scheduling control module. If it is agreed, it initiates a double rate synchronous dynamic random access memory request to the double rate synchronous dynamic random access memory controller scheduling control module; if it is not agreed, it suspends the request until it is agreed; the number of requests to the double rate synchronous dynamic random access memory controller and the number of times the double rate synchronous dynamic random access memory control right is obtained are notified to the corresponding fine-grained probability balance adjustment module and the coarse-grained probability balance adjustment module; and in this process, in order to prevent the blockage of a single channel, the request to the double rate synchronous dynamic random access memory controller is suspended and then the request is sent again, and the number of requests needs to be accumulated;

[0131] The controller scheduling control module is responsible for polling and scheduling the double rate synchronous dynamic random access memory request sent by the double rate synchronous dynamic random access memory transmission request module A / B / C;

[0132] The double rate synchronous dynamic random access memory controller is responsible for reading and writing control of the double rate synchronous dynamic random access memory;

[0133] A double rate synchronous dynamic random access memory storage unit is also a double rate synchronous dynamic random access memory;

[0134] The processor module is the computing and control core of the computer system and the final execution unit for information processing and program operation. If an interrupt signal is received from the output control module, the compressed image data is read out from the double-rate synchronous dynamic random access memory and sent to the other end together with the network module A, and then the interrupt is cleared.

[0135] The remote network module is used for network transmission and is responsible for sending data to the network module B at the other end;

[0136] The local network module is used for network transmission and is responsible for receiving data sent by the peer network module A;
