[0050] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of illustration, and not of limitation, the principles of the present application. The same or similar components have the same reference numbers throughout the drawings.

It should be further understood that the terms "comprises," "comprising," "includes," "including," and the like, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0052] In order to make the purposes, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0053] First, several terms related to the present application are introduced and explained:

[0054] (1) PCIE system. A PCIE system is generally composed of a root complex, a switch, an endpoint device, a PCIE-to-PCI / PCI-X bridge, and the like, as shown in FIG. 2. Figure 1As shown, the root complex is an important component of the PCIE architecture, and the CPU implements initialization and configuration of the endpoint device through the root complex, and allocates bar space to each endpoint device.

[0055] In actual applications, the root complex generally allocates bar space to the endpoint device according to the bar space of the endpoint device itself, and in general cases, the bar space allocated to the endpoint device by the root complex matches the bar space of the endpoint device. Different service types transmitted between the root complex and the endpoint device in a system are distinguished by preset offset addresses. For example, in a certain system, the endpoint device needs to receive upgrade data, image data, and register data, and the endpoint device parses different service types according to the preset offset addresses of the services. For a system, the root complex generally allocates only one fixed bar space to the endpoint device, but in some applications, the root complex needs to reallocate the bar space of the endpoint device. When the bar space reallocated by the root complex to the endpoint device does not match the fixed bar space of the endpoint device itself, the root complex and the endpoint device cannot communicate.

[0056] The technical problem to be solved by the service parsing method and device, the electronic device, and the computer storage medium provided in the present application is to solve the above technical problem of the prior art.

[0057] The technical solution of the present application and how the technical solution of the present application solves the above technical problem will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0058] A service parsing method is provided in the embodiments of the present application, which is applied to a PCIE system. As shown in the figure, the method comprises the following steps. Figure 2 The method comprises the following steps.

[0059] In step S201, the endpoint device is scanned, and the maximum link width of the endpoint device is obtained.

[0060] In the disclosed embodiment, a PCIE scan is performed on an endpoint device through a root complex to obtain information about the current endpoint device, such as the maximum link width of the endpoint device. When it is determined that the maximum link width of the endpoint device is a first preset value, such as 2, it indicates that the bar space address of the endpoint device needs to be reallocated. The root complex reallocates the bar space address for the endpoint device and configures the maximum payload width of the endpoint device to the first preset value (such as 256) to inform the endpoint device that the bar space address has been reallocated. The endpoint device will then restrict the address of the received service packet to be parsed and block invalid address space. When it is determined that the maximum link width of the endpoint device itself is a second preset value, such as 4, it indicates that the bar space address of the endpoint device does not need to be reallocated. The root complex will configure the maximum payload width of the endpoint device to the second preset value (such as 1024) to inform the endpoint device that its bar space address has not been reallocated. When receiving the service packet to be parsed, the endpoint device will not restrict the address of the received service packet to be parsed and will directly parse the service packet based on the address of the service packet to be parsed.

[0061] Step S202: when the maximum link width of the endpoint device is a first preset value, reallocate a bar space address for the endpoint device;

[0062] In the implementation of this application, when the maximum link width of the endpoint device is determined to be a first preset value, such as 2, it indicates that the bar space address of the endpoint device needs to be reallocated. The root complex fully allocates the bar space address for the endpoint device. The endpoint device will restrict the address of the received business packet to be parsed and block invalid address space.

[0063] Step S203: receiving a service package to be parsed based on the bar space address, and updating the address in the service package to be parsed, where the address in the service package to be parsed is used to characterize the service parsing type;

[0064] In an embodiment of the present application, the service packet to be parsed refers to a packet containing service data sent by the root complex in the PCIE system to the endpoint device, wherein the root complex and the endpoint device communicate through routing addressing, and an address is set in the service packet to be parsed, which includes a first address segment for representing the bar space address configured by the root complex for the endpoint device, a second address segment for representing the service parsing type, and a third address segment for representing the storage location of the service to be processed.

[0065] For the convenience of explanation, a specific embodiment is taken as an example. Figure 3 As shown, the bar space address allocated by the root complex to the endpoint device is 2 0 ~2 n-3 , the address of the business package to be parsed is 20 ~2 n-3 , wherein the second address segment for indicating the service type in the service packet to be parsed is an address bit of a preset value. In the embodiment of the present application, the second address segment can be selected as 2 n-3 ~2 n-4 Address bit, the category of the service contained in the service packet to be parsed is service 1. According to the preset value rule, the address corresponding to service 1 is 00. In the second address segment 2 of the service packet to be parsed, n-3 ~2 n-4 The address bits are 00, and the third address segment is used to represent the storage location of service 1. If the highest address bit of the first address segment refers to the first address bit of the service packet to be parsed, when the highest address bit of the first address segment of the service packet to be parsed is within the second address segment, the second address segment of the service packet to be parsed needs to be updated based on the highest address bit of the first address segment to ensure that the service type represented by the second address segment remains unchanged.

[0066] For the convenience of explanation, a specific embodiment is taken as an example. Figure 4 As shown, the first address segment of the service packet to be parsed is 2 0 ~2 n-3 , of which 2 n-3 The address bit is 1, and the third address segment is 2 0 ~2 n-5 , used to represent the location where business data is stored, the second address segment is 2 n-4 ~2 n-3 , where the service to be parsed is service 1, then the address of the second address segment corresponding to it is 00, that is, in the second address segment, 2 n-4 ~2 n-3 The addresses in are 0, 2 n-3 The address bit is the highest address bit of the first address segment, and the highest address is within the second address segment. When the second address segment is packaged into the service package to be parsed, the overlapping part of the second address segment and the first address segment will be calculated to obtain the address of the service package to be parsed. After receiving the parsed service package, the endpoint device needs to first restrict the address of the service package to be parsed to ensure that the service type represented by the second address segment in the service package to be parsed remains unchanged. In this case, 2 n-3 The address in the address bit is modified to 0 accordingly to ensure that the second address segment 2 n-4 ~2 n-3 The address is 00.

[0067] Step S204: Parse the service package to be parsed according to the updated address in the service package to be parsed to obtain a parsing result.

[0068] In the embodiment of the present application, after the second address segment is updated, the type of the service in the to-be-resolved service packet is determined based on the updated second address segment, and the to-be-resolved service packet is resolved to obtain service data.

[0069] In the embodiment of the present application, the address of the to-be-resolved service packet is divided into a first address segment representing a bar space address configured by the root complex for the endpoint device, a second address segment representing a service resolution type, and a third address segment representing a storage location of a to-be-processed service. When it is determined that the address in the first address segment has an impact on the second address segment representing the service resolution type, the second address segment is adjusted, and the service is resolved based on the adjusted second address segment to obtain a resolution result. The root complex can successfully receive the to-be-resolved service packet when the bar space address allocated by the root complex for the endpoint device does not match the bar space size of the endpoint device, and can correctly resolve the to-be-resolved service, thereby ensuring the normal operation of the PCIE system.

[0070] The embodiment of the present application provides a possible implementation, in which after the maximum link width of each endpoint device is obtained, the method further includes:

[0071] When it is determined that the maximum link width of the endpoint device itself is a second preset value, the bar space address is not re-allocated for the endpoint device.

[0072] In the embodiment of the present application, after the maximum link width of the endpoint device is obtained, when it is determined that the maximum link width of the endpoint device itself is a second preset value, such as 4, it is indicated that the bar space address of the endpoint device does not need to be re-allocated, and the address of the to-be-resolved service packet received by the endpoint device is not limited, and the service packet is directly resolved based on the address of the to-be-resolved service packet.

[0073] The embodiment of the present application provides a possible implementation, in which the address in the to-be-resolved service packet includes a first address segment representing a bar space address configured by the root complex for the endpoint device, a second address segment representing a service resolution type, and a third address segment representing a storage location of a to-be-processed service. The updating of the address in the to-be-resolved service packet includes:

[0074] If the highest address bit of the first address segment is in the second address segment, the second address segment in the address of the to-be-resolved service packet is updated according to the highest bit address in the first address segment;

[0075] The resolving of the to-be-resolved service packet according to the updated address in the to-be-resolved service packet includes:

[0076] The service to be processed is determined according to the third address segment, and the service to be processed is parsed according to the service parsing type represented by the updated second address segment.

[0077] In an embodiment of the present disclosure, an address is set in the service package to be parsed, which includes a first address segment for representing the bar space address configured by the root complex for the endpoint device, a second address segment for representing the service parsing type, and a third address segment for representing the storage location of the service to be processed.

[0078] For the convenience of explanation, a specific embodiment is used as an example. Figure 3 As shown, the bar space address allocated by the root complex to the endpoint device is 2 0 ~2 n-3 , the address of the business package to be parsed is 2 0 ~2 n-3 , wherein the second address segment for indicating the service type in the service packet to be parsed is an address bit of a preset value. In the embodiment of the present application, the second address segment can be selected as 2 n-3 ~2 n-4 Address bit, the category of the service contained in the service packet to be parsed is service 1. According to the preset value rule, the address corresponding to service 1 is 00. In the second address segment 2 of the service packet to be parsed, n-3 ~2 n-4 The address bits are 00, and the third address segment is used to represent the storage location of the service 1.

[0079] In the embodiment of the present disclosure, the highest address bit of the first address segment refers to the first address bit of the business packet to be parsed. When the highest address bit of the first address segment of the business packet to be parsed is within the second address segment, it is necessary to update the second address segment in the business packet to be parsed according to the highest address bit of the first address segment to ensure that the business type represented by the second address segment remains unchanged.

[0080] For the convenience of explanation, a specific embodiment is used as an example. Figure 4 As shown, the first address segment of the service packet to be parsed is 2 0 ~2 n-3 , of which 2 n-3 The address bit is 1, and the third address segment is 2 0 ~2 n-5 , used to represent the location where business data is stored, the second address segment is 2 n-4 ~2 n-3 , where the service to be parsed is service 1, then the address of the second address segment corresponding to it is 00, that is, in the second address segment, 2 n-4 ~2 n-3 The addresses in are 0, 2 n-3The address bit is the highest address bit of the first address segment, and the highest address is within the second address segment. When the second address segment is packaged into the service package to be parsed, the overlapping part of the second address segment and the first address segment will be calculated to obtain the address of the service package to be parsed. After receiving the parsed service package, the endpoint device needs to first restrict the address of the service package to be parsed to ensure that the service type represented by the second address segment in the service package to be parsed remains unchanged. In this case, 2 n-3 The address in the address bit is modified to 0 accordingly to ensure that the second address segment 2 n-4 ~2 n-3 The address is 00.

[0081] In the embodiment of the present application, after the second address segment is updated, the type of service in the service packet to be parsed is determined based on the updated second address segment, and the service packet to be parsed is parsed to obtain service data.

[0082] The present application embodiment provides a possible implementation method, in which, Figure 5 As shown, updating the second address segment in the address of the service packet to be parsed according to the highest address in the first address segment includes:

[0083] Step S501 : determining a target address bit in the second address segment, where the target address bit is the address bit in the second address segment corresponding to the highest address bit in the first address segment.

[0084] In an embodiment of the present application, the target address bit refers to an address bit in the second address segment, and the position of the target address bit in the address carried by the business packet to be parsed is the same as the position of the highest address bit of the first address segment in the address carried in the business packet to be parsed.

[0085] For the convenience of explanation, a specific embodiment is used as an example. Figure 6 As shown, for a service packet to be parsed, the second address segment is 2 n-4 ~2 n-3 , the first address segment is 2 0 ~2 n-3 , where the highest address bit of the first address segment is 2 n-3 , then the highest address bit in the first address segment of the service packet to be parsed and an address bit in the second address segment are in the same position in the service packet to be parsed, that is, 2 n-3 address bit, then the address bit is determined as the target address bit. Optionally, in the first address segment, the address of the address bit is 1, and in the second address segment, the address of the address bit is 0.

[0086] Step S502, performing an OR operation between the target address bit and the highest address bit, and if the operation result is inconsistent with the target address bit, adjusting the target address to 0.

[0087] In the embodiment of the present application, after the target address bit is determined, an OR operation is performed between the target address bit and the highest address bit, and if the operation result is inconsistent with the target address bit, the target address is adjusted to 0.

[0088] For the embodiment of the present application, for the convenience of description, a specific embodiment is taken as an example, as shown in FIG. 6, the address in the target address bit in the second address segment is 0, the corresponding address bit in the first address segment is 1, and the result of 0 OR 1 is 1, at this time, the address in the second address segment is 10, and the type of the service in the service packet to be parsed is service 1, and the corresponding second address segment should be 00, therefore, the target address in the second address segment in the service packet to be parsed needs to be adjusted to 0, so as to ensure that the type of the service guaranteed by the target address is service 1. Figure 6

[0089] The embodiment of the present application determines the target address bit in the second address segment, performs an OR operation between the target address bit and the highest address bit, and if the operation result is inconsistent with the target address bit, adjusts the target address to 0, so as to ensure that the type of the service represented by the second address segment is unchanged.

[0090] The embodiment of the present application provides a possible implementation, in which the method further comprises:

[0091] If the operation result is consistent with the address of the target address, the address of the target address bit remains unchanged.

[0092] For the embodiment of the present application, for the convenience of description, a specific embodiment is taken as an example, as shown in FIG. 6, the address in the target address bit in the second address segment is 0, the corresponding address bit in the first address segment is 1, and the result of 0 OR 1 is 1, at this time, the address in the second address segment is 10, and the type of the service in the service packet to be parsed is service 1, and the corresponding second address segment should be 00, therefore, the target address in the second address segment in the service packet to be parsed needs to be adjusted to 0, so as to ensure that the type of the service guaranteed by the target address is service 1. Figure 7

[0093] When the maximum link width of the endpoint device is the first preset value, the maximum load width of the endpoint device is configured as the first load width.

[0094] When the maximum link width of the endpoint device is the second preset value, the maximum load width of the endpoint device is configured as the second load width.

[0095] ​​In the embodiments of the present disclosure, in the embodiments of the present application, after the root complex obtains the maximum link width of the endpoint device, whether to perform the re-allocation of the BAR space address of the endpoint device is selected based on the maximum link width of each endpoint device, and the root complex needs to inform the endpoint device of the information whether the re-allocation of the BAR space address of the endpoint device is performed, in the embodiments of the present application, the information can be informed by configuring the maximum load width of the endpoint device, different maximum load widths are configured for the endpoint device for the two cases that the re-allocation of the BAR space address of the endpoint device is performed or the re-allocation of the BAR space address of the endpoint device is not performed, and the maximum load width is used to inform the endpoint device whether the BAR space address of the endpoint device is re-allocated.

[0096] For the embodiments of the present application, for the convenience of description, taking one specific embodiment as an example, in a PCIE system, there are three endpoint devices connected with the root complex, including an endpoint device A, an endpoint device B and an endpoint device C, after the PCIE system is started, the root complex starts to scan each endpoint device to obtain the device information of each endpoint device, wherein, for example, the maximum link width of each endpoint device, the maximum link width of the endpoint device A is 2, the maximum link width of the endpoint device B is 2, and the maximum link width of the endpoint device C is 4. Of course, when the root complex obtains the device information of the endpoint device, other information of the endpoint device can also be obtained, such as identity information, model information, etc. In the embodiments of the present application, when the maximum link width of the endpoint device is 2, it indicates that the BAR space address of the endpoint device needs to be re-allocated, and the root complex will forcibly re-allocate the BAR space address of the endpoint device, and configure the maximum load width of the endpoint device as a first load width, such as 256, when the endpoint device learns that the maximum load width of itself is configured as the first load width (256), it is determined that the BAR space address of itself is re-allocated, and when the endpoint device receives a to-be-analyzed service packet, the address of the to-be-analyzed service packet will be limited. As another embodiment of the present application, when the maximum link width of the endpoint device is 4, it indicates that the BAR space address of the endpoint device does not need to be re-allocated, and the root complex will configure the maximum load width of the endpoint device as a second load width, such as 1024, when the endpoint device learns that the maximum load width of itself is configured as the second load width (1024), it is determined that the BAR space address of itself is not re-allocated, and when the endpoint device receives a to-be-analyzed service packet, the address of the to-be-analyzed service packet will not be limited.

[0097] In the embodiments of the present application, by configuring the maximum load width of the endpoint device, the endpoint device is informed whether the BAR space address of itself is re-allocated, and the endpoint device is facilitated to limit the address of the received to-be-analyzed service packet in the case that the BAR space address is re-allocated.
