Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a resource allocation method, apparatus, electronic device, and storage medium for a data processing unit. Background Technology

[0002] With the rapid growth and increasing complexity of data, many applications need to handle massive datasets. Traditional CPUs (Central Processing Units) may experience performance bottlenecks when handling this type of workload. Therefore, dedicated hardware devices for accelerating data processing, namely Data Processing Units (DPUs), have been introduced. DPUs can leverage their specific architecture and hardware design to efficiently execute parallel computing tasks, thus providing better performance and acceleration. Furthermore, DPUs are also commonly used in network devices, including processing data packets, executing protocol stacks, and network functions such as firewalls and VPNs (Virtual Private Networks). This helps improve network throughput, reduce latency, and support higher levels of network security and quality of service.

[0003] To better utilize the DPU, the BIOS (Basic Input Output System) must allocate the bus and MMIO (Memory-Mapped I / O) resources required by the DPU during the boot process to meet the DPU's operating environment. Currently, resources are allocated directly to the bus location where the DPU resides during BIOS startup, or during device enumeration, the device ID and vendor ID are checked to determine if the device is a DPU device before resource allocation. This allocation method is simplistic, and any changes in hardware location or link design require code modification and re-adaptation. This approach is clearly inflexible and wastes manpower.

[0004] Therefore, there is an urgent need to propose a resource allocation method, device, electronic device, and storage medium for a data processing unit that can improve the flexibility and accuracy of resource allocation. Summary of the Invention

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0059] Example 1

[0060] In one embodiment, such as Figure 1 As shown, a resource allocation method for a data processing unit is provided, applied to a basic input / output system. The method includes:

[0061] In response to the basic input / output system booting to the pre-firmware interface initialization phase, the position variables stored in the memory are read, where the position variables contain the initial position information of the data processing unit;

[0062] In response to the successful reading of the location variable, resources are reserved for the data processing unit based on the initial location information;

[0063] In response to the basic input / output system continuing to boot into the PCIe device enumeration stage, multiple PCIe devices are traversed to obtain the corresponding identification information, and the data processing unit is determined to be in place based on the multiple identification information;

[0064] In response to the presence of the data processing unit, obtain the current location information of the data processing unit;

[0065] Based on the current location information and the initial location information, determine whether to allocate resources to the data processing unit according to the initial location information and resource reservation.

[0066] Specifically, resource reservation is performed based on the initial position information of the data processing unit pre-stored in the memory, which improves the accuracy of resource allocation for the data processing unit; then, based on the comparison result between the current position information and the initial position information of the data processing unit, it is determined whether to allocate resources to the data processing unit according to the initial position information and the resource reservation status, which improves the flexibility of resource allocation for the data processing unit.

[0067] In one embodiment, reserving resources for the data processing unit based on initial location information includes:

[0068] Obtain the first total resource amount, where the first total resource amount represents the total amount of bus resources;

[0069] Calculate the first fixed resource reserve based on the first total resource amount;

[0070] Subtract the first fixed resource reserve from the first total resource amount to obtain the first resource reserve to be allocated;

[0071] The first resource reservation amount of the data processing unit is calculated based on the initial location information, wherein the first resource reservation amount is less than the first resource reservation amount to be allocated;

[0072] Obtain the second total resource amount, where the second total resource amount represents the total amount of memory-mapped input / output resources;

[0073] Calculate the second fixed resource reserve based on the second total resource amount;

[0074] Subtract the second fixed resource reserve from the second total resource amount to obtain the second resource reserve to be allocated;

[0075] The second resource reservation amount of the data processing unit is calculated based on the initial location information, wherein the second resource reservation amount is less than the second resource reservation amount to be allocated.

[0076] Specifically, the first and second resource reservations are calculated to facilitate subsequent resource allocation to the data processing unit, thereby improving the accuracy of resource allocation within the data processing unit.

[0077] In a specific embodiment, when allocating bus resources, a first resource reservation main function, such as `CalculateBusResourcesPerSocket()`, first calculates how many buses need to be reserved in the socket for UBOX / accelerators, etc. Then, a first preset function `AddRsvdBus()` is added to the first resource reservation main function to determine how many buses need to be reserved in the socket for the DPU based on the initial position information of the DPU stored in the position variable. Similarly, a second resource reservation main function, such as `CalculateMmiolResources()`, first calculates the fixed reserved mmio resources. Then, a second preset function `AddRsvdMmio()` is added to the second resource reservation main function to determine how many mmio resources to allocate to the DPU based on the initial position information of the DPU.

[0078] In one embodiment, calculating the first resource reservation amount for the data processing unit based on initial location information includes:

[0079] The interface information of the data processing unit is obtained from the initial location information. The interface information includes the interface connection type and the corresponding number of root ports. The interface connection type includes the first interface connection type and the second interface connection type.

[0080] In response to the interface connection type being the first interface connection type, the first resource reservation amount of the data processing unit is calculated based on the number of root ports corresponding to the first interface type;

[0081] In response to the interface connection type being the second interface connection type, the first resource reservation amount of the data processing unit is calculated based on the number of root ports corresponding to the second interface type.

[0082] Specifically, based on the interface connection type and the corresponding number of root ports in the initial location information, the first resource reservation is determined so that the first resource reservation can be allocated to the data processing unit later, thereby improving the accuracy of resource allocation for the data processing unit.

[0083] In a specific implementation, the SetBusBaseAndLimit() function calculates how many buses each stack is specifically assigned to. For example... Figure 2 As shown, the first interface connection type, Single-host, occupies a x16 root port, so 64 buses need to be allocated to the corresponding stack. The second interface connection type, Multi-host, occupies two x8 root ports, and theoretically, 32 buses should be allocated to the corresponding stack. At this point, we need to pay attention to the compatibility with hardware devices. The first 8 lanes of some PE ports may contain hardware devices such as VGA / M.2 / USB, so these ports need to be allocated separately. For example, allocate (32+7) buses (VGA:2, M.2:2, USB:1, RootPort:1) to this stack. If the stack does not contain other hardware, allocate (32+3) buses.

[0084] In one embodiment, calculating the second resource reservation amount for the data processing unit based on the initial location information includes:

[0085] The interface information of the data processing unit is obtained from the initial location information. The interface information includes the interface connection type and the corresponding number of root ports. The interface connection type includes the first interface connection type and the second interface connection type.

[0086] In response to the interface connection type being the first interface connection type, the second resource reservation amount of the data processing unit is calculated based on the number of root ports corresponding to the first interface type;

[0087] In response to the interface connection type being the second interface connection type, the second resource reservation amount of the data processing unit is calculated based on the number of root ports corresponding to the second interface type.

[0088] Specifically, based on the interface connection type and the corresponding number of root ports in the initial location information, the second resource reservation is determined so that the second resource reservation can be allocated to the data processing unit later, thereby improving the accuracy of resource allocation for the data processing unit.

[0089] In one embodiment, such as Figure 3As shown, multiple PCIe devices are traversed to obtain corresponding identification information, and the presence of the data processing unit is determined based on the identification information, including:

[0090] Iterate through multiple PCIe devices to obtain multiple corresponding first identification information, wherein the first identification information includes the device ID and manufacturer ID of the corresponding PCIe device;

[0091] Obtain the second identification information stored in the memory, wherein the second identification information includes the device ID and manufacturer ID of the data processing unit;

[0092] The second identifier information is matched with multiple first identifier information to obtain the identifier matching result;

[0093] The presence of the data processing unit is determined based on the identifier matching result.

[0094] In one embodiment, determining whether a data processing unit is in place based on the identifier matching result includes:

[0095] In response to the identifier matching result indicating that the second identifier information successfully matches one of the first identifier information, it is determined that the data processing unit is in place;

[0096] In response to the identifier matching result indicating that the second identifier information fails to match with multiple first identifier information, it is determined that the data processing unit is not in place.

[0097] In one embodiment, determining whether to allocate resources to the data processing unit based on the current location information and the initial location information, and the resource reservation status, includes:

[0098] The current location information is compared with the initial location information to obtain the location comparison result;

[0099] In response to the location comparison result indicating that the current location information is inconsistent with the initial location information, the initial location information in the location variable is changed to the current location information, and resources are allocated to the data processing unit according to the current location information and resource reservation.

[0100] In response to the location comparison result indicating that the current location information is consistent with the initial location information, resource allocation is performed on the data processing unit based on the initial location information and resource reservation.

[0101] The resource reservation status includes the first resource reservation amount and the second resource reservation amount.

[0102] Specifically, the initial location information includes the initial address of the data processing unit, and the current location information includes the current address of the data processing unit. Based on the location comparison result, it is determined whether to allocate the first resource reservation and the second resource reservation to the initial address or the current address of the data processing unit, thereby improving the flexibility of resource allocation for the data processing unit.

[0103] In one embodiment, such as Figure 3 As shown, the method also includes:

[0104] In response to a location variable read failure, wait for the Basic Input / Output System to enter the PCIe device enumeration phase;

[0105] In response to the basic input / output system continuing to boot into the PCIe device enumeration stage, multiple PCIe devices are traversed to obtain the corresponding identification information, and the data processing unit is determined to be in place based on the multiple identification information;

[0106] In response to the presence of the data processing unit, the current location information of the data processing unit is obtained, and resources are reserved for the data processing unit based on the current location information;

[0107] Allocate resources to the data processing unit based on current location information and resource reservation status;

[0108] In response to the data processing unit being out of place, the current location information of the data processing unit is set to empty, and the location comparison result is set to inconsistent;

[0109] Change the initial position information in the position variable to empty, and reallocate resources to the data processing unit.

[0110] Specifically, when reading a location variable fails and the data processing unit is in place, resources are reserved based on the current location information, and resources are allocated to the data processing unit based on the current location information and resource reservation. When reading a data variable fails and the data processing unit is not in place, resources are reallocated to the data processing unit. This improves the flexibility and accuracy of resource allocation for the data processing unit.

[0111] It should be understood that, although Figure 1 , Figure 3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1 , Figure 3At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.
