Description

Technical Field

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

[0002] With the rapid growth of data volume and increasing complexity, many applications need to process large-scale data sets. Traditional CPUs (Central Processing Units) may have performance bottlenecks when processing this type of workload. Therefore, a hardware device specifically designed to accelerate data processing, namely DPU (Data Processing Unit), was introduced. DPU can efficiently perform parallel computing tasks using its specific architecture and hardware design, thereby providing better performance and acceleration. And 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 to improve network throughput, reduce latency, and support higher levels of network security and quality of service.

[0003] In order to make better use of the DPU, the BIOS (Basic Input Output System) must allocate the bus resources and mmio (Memory-Mapped I / O) resources required by the DPU in advance during the boot process to meet the operating environment of the DPU. Currently, fixed resources are directly allocated to the bus position where the DPU is located during the BIOS startup process, or the device ID and manufacturer ID of the device are determined to be a DPU device during the device enumeration process, and then resources are allocated to the device. The allocation method is single, and once the hardware position changes or the link design changes, the code needs to be modified and re-adapted. This allocation method is obviously not flexible enough and causes a waste of 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 of the data processing unit. Summary of the invention

[0058] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0059] Embodiment 1

[0060] In one embodiment, Figure 1 As shown, a resource allocation method for a data processing unit is provided, which is applied to a basic input and output system, and the method includes:

[0061] In response to the basic input and output system starting up to the pre-firmware interface initialization phase, reading the position variable stored in the memory, wherein the position variable includes initial position information of the data processing unit;

[0062] In response to the position variable being read successfully, reserving resources for the data processing unit according to the initial position information;

[0063] In response to the basic input and output system continuing to start up to the PCIE device enumeration phase, traversing multiple PCIE devices to obtain corresponding multiple identification information, and judging whether the data processing unit is in place according to the multiple identification information;

[0064] In response to the data processing unit being in position, obtaining current position information of the data processing unit;

[0065] According to the current location information and the initial location information, it is determined whether to allocate resources to the data processing unit according to the initial location information and the resource reservation status.

[0066] Specifically, resource reservation processing is performed based on the initial position information of the data processing unit pre-stored in the memory, thereby improving the accuracy of resource allocation of the data processing unit; then, based on the comparison result of 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 based on the initial position information and the resource reservation situation, thereby improving the flexibility of resource allocation of the data processing unit.

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

[0068] Acquire a first total amount of resources, wherein the first total amount of resources represents a total amount of bus resources;

[0069] Calculating a first fixed resource reservation amount based on the first total resource amount;

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

[0071] Calculate a first resource reservation amount of the data processing unit according to the initial position information, wherein the first resource reservation amount is less than a first resource reservation amount to be allocated;

[0072] Obtaining a second total amount of resources, wherein the second total amount of resources represents a total amount of memory-mapped input / output resources;

[0073] Calculating a second fixed resource reservation amount based on the second total resource amount;

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

[0075] A second resource reservation amount of the data processing unit is calculated according to the initial position information, wherein the second resource reservation amount is smaller than the second resource reservation amount to be allocated.

[0076] Specifically, the first resource reservation amount and the second resource reservation amount are calculated so as to allocate resources to the data processing unit later, thereby improving the accuracy of resource allocation to the data processing unit.

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

[0078] In one embodiment, calculating the first resource reservation amount of the data processing unit according to the initial location information includes:

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

[0083] In a specific embodiment, the number of buses allocated to each stack is calculated in the SetBusBaseAndLimit() function. Figure 2 As shown, the first interface connection type Single-host connection occupies the x16 root port, so 64 buses should be allocated to the corresponding stack; the second interface connection type multi-host connection occupies two x8 root ports, and theoretically 32 buses should be allocated to the corresponding stack. At this time, we must pay attention to the matching with the hardware devices. The first 8 lanes of some PE ports will contain some hardware devices such as VGA / M.2 / USB, so these ports must be allocated separately. For example, (32+7) (VGA: 2, M.2: 2, USB: 1, RootPort: 1) buses are allocated to this stack. If the stack does not contain other hardware, (32+3) buses are allocated.

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

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

[0089] In one embodiment, Figure 3As shown, traversing multiple PCIE devices to obtain corresponding multiple identification information, and judging whether the data processing unit is in place according to the multiple identification information, including:

[0090] Traversing multiple PCIE devices to obtain corresponding multiple first identification information, wherein the first identification information includes a device ID and a manufacturer ID of the corresponding PCIE device;

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

[0092] Matching the second identification information with the plurality of first identification information to obtain an identification matching result;

[0093] Determine whether the data processing unit is in place according to the identification matching result.

[0094] In one embodiment, determining whether the data processing unit is in place according to the identification matching result includes:

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

[0096] In response to the identification matching result indicating that the second identification information fails to match the plurality of first identification 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 according to the initial location information and the resource reservation status according to the current location information and the initial location information includes:

[0098] Compare the current location information with the initial location information to obtain a location comparison result;

[0100] In response to the position comparison result indicating that the current position information is consistent with the initial position information, allocating resources to the data processing unit according to the initial position information and the resource reservation status;

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

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

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

[0104] In response to a failure to read the position variable, waiting for the basic input and output system to enter a PCIE device enumeration phase;

[0105] In response to the basic input and output system continuing to start up to the PCIE device enumeration phase, traversing multiple PCIE devices to obtain corresponding multiple identification information, and judging whether the data processing unit is in place according to the multiple identification information;

[0106] In response to the data processing unit being in place, obtaining current location information of the data processing unit, and reserving resources for the data processing unit according to the current location information;

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

[0108] In response to the data processing unit being not in place, setting the current position information of the data processing unit to null, and setting the position comparison result to inconsistent;

[0109] The initial position information in the position variable is changed to empty, and resources are reallocated to the data processing unit.

[0110] Specifically, when the position variable fails to be read and the data processing unit is in place, resources are reserved according to the current position information, and resources are allocated to the data processing unit according to the current position information and resource reservation; when the data variable fails to be read and the data processing unit is not in place, resources are re-allocated to the data processing unit. This improves the flexibility and accuracy of resource allocation of the data processing unit.

[0111] It should be understood that although Figure 1 , Figure 3 The steps in the flowchart are shown in sequence 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 restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1 , Figure 3At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed 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 part of the sub-steps or stages of other steps.
