All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. 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 listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

In the embodiment of the present application, the Data Processor (DPU) may be a dedicated processor with a data-centric structure, and may support infrastructure layer resource virtualization by using a software-defined technology route, so as to support infrastructure layer services such as storage, security, and quality of service management.

In the embodiment of the application, the virtio is an abstraction layer located above a device in a semi-virtualized hypervisor, and the virtio-net driver refers to a network device virtualization mode. The virtio-PCI refers to a Peripheral Component Interconnect (PCI) standard interface of the paravirtualized device, and the virtio-net driver is a paravirtualized network driver.

The following describes embodiments of the present application in detail.

In the related art, since the virtio-pci and virtio-net drivers are integrated in a Linux kernel, the application of the virtio-net device does not need to additionally install a private driver of a hardware manufacturer. In recent years, virtio-net equipment is more and more widely used in barrel-metal, cloud-native and virtual machine virtualization scenes. Therefore, most DPU vendors support the provision of virtio-net devices that conform to the virtio protocol standard.

The initial purpose of virtio application is that in virtualization, based on the collaborative design of a backend simulation device which drives a front end of a virtual machine to qemu, the software virtiovring is used for realizing front-end and back-end communication, and the capability of the device by means of special equipment is lack of consideration. Whereas DPU hardware provides a large amount of hardware capabilities that are not well utilized in hardware virtio-net devices, these hardware capabilities may include mac _ spoof-check, mtu modification, QOS scheduling, etc.

In the related art, the virtio-net protocol does not realize mac _ zoof-check, mtu modification and quality of service (QOS) scheduling. Thus, there is no mechanism for the front-end virito-net driver to notify the back-end virtio-net device.

In order to utilize the hardware capabilities, most manufacturers separately develop a set of configuration management software, and the management software receives user configuration and then notifies the DPU through RPC, so that the DPU issues device capability resources.

Further, as shown in fig. 1, a method of hardware capability of a virtio-net device is mainly configured by a user through RPC and the like, and then a user management and control platform notifies the DPU through user management software through RPC and the like of a DPU manufacturer, an ECPU of the DPU runs resource management software, and a socket server (socket server) runs to monitor user configuration.

The user management and control platform may be a HOST front end, and the DPU may include a field-programmable gate array (field-programmable array)/Application Specific Integrated Circuit (ASIC) and an embedded CPU (embedded CPU, ECPU) back end, as shown in fig. 2, and each module may be in communication connection with each other.

Because the DPU manufacturers need to additionally develop the configuration management software with these hardware capabilities, and there is no unified standard, the management and control platform of the customer needs to adapt to the configuration management software of each DPU manufacturer, which results in large workload and poor expandability.

Based on the defects of the related art, please refer to fig. 3, where fig. 3 is a schematic flowchart of another hardware capability calling method provided in an embodiment of the present application, and is applied to a paravirtualization device, as shown in the figure, the hardware capability calling method includes:

The method of the control-queue is as follows, and the message format of the control-queue can be set as follows:

struct virtio_net_ctrl{

u8 class；

u8 command；

u8 command-specific-data[]；

u8 ack；

}

wherein u8 class is a command class and is set by virtio-net drive; u8 command is a command subclass, set by virtio-net driver; u8 command-specific-data [ ] is command specific data, set by virtio-net driver; u8 ack is the command return status, set by the DPU hardware, identifying whether the command was processed successfully.

Further, each hardware capability is added with a class definition and a command capability, which is shown as follows, and the specification issued by virtio is subject to:

#define VIRTIO_NET_MAC_SPOOF_CHECK 5

#define VIRTIO_NET_QDISC_DEL 1

......

#define VIRTIO_NET_MTU_MODIFY 7

#define VIRTIO_NET_MTU_SET 0

……

wherein, # define VIRTIO _ NET _ MAC _ SPOOF _ CHECK corresponds to the class field in the struct virtual _ NET _ ctrl structure, and the downstream MAC prevents the fraud CHECK; the # define VIRTIO _ NET _ MAC _ SPOOF _ CHCK _ SEC corresponds to a command field in the struct virtual _ NET _ ctrl structure; the # define VIRTIO _ NET _ TC corresponds to a class field in a structvirtio _ NET _ ctrl structure body, and flow control is carried out; the # definition VIRTIO _ NET _ QDISC _ ADD corresponds to a command field in the struct virtual _ NET _ ctrl structure; the # definition VIRTIO _ NET _ QDISC _ DEL corresponds to a command field in the struct VIRTIO _ NET _ ctrl structure; the # define VIRTIO _ NET _ MTU _ MODIFY corresponds to a class field in the structure of struct virtual _ NET _ ctrl, and the maximum transmission unit is modified; and # defineVIRTIO _ NET _ MTU _ SET corresponds to the command field in the struct virtual _ NET _ ctrl structure.

le16 status；

le16 max_virtqueue_pairs；

le16 mtu；

u8 mac_spoof_check；

u8 resv[3]；

struct tc_mqprio_qopt；}

in the embodiment of the application, a user management and control platform can be enabled to only use a general interface to configure the hardware capability of the virito-net, and the using method is as shown in fig. 4, in the specific implementation, the paravirtualized device may include a virtio driver, and the virtio driver initializes the device feature according to the virtio-pci common-cfg capability set; the virtio-net initializes and registers an ops interface of netdev; then, the user management and control platform configures the hardware capability of the virtio-net equipment through a universal command line of the netdev, namely, the user management software informs a virtio driver (virtio-net driver) through ops of the DP standard netdev; after receiving the configuration, the virtio driver judges whether the hardware has the forwarding capability according to the acquired device feature, if so, the hardware is issued to the DPU in a bar register writing mode of a virtio-netcontrol-queue or virtio-pci device-cfg capability set, namely, the DPU can be judged to have the forwarding capability according to the equipment features negotiated before (in an initialization stage) and then issued, and if not, an error is reported.

In a specific implementation, a virtio driver acquires a device feature of a virtio-net device, a virtio specification increases a device feature (device feature) corresponding to a hardware capability of the virtio-net, and an increased device feature byte (feature bit) can be represented as follows:

VIRTIO_NET_F_MAC_SPOOF_CHECK(24)

VIRTIO_NET_F_QOS(25)

VIRTIO_NET_MTU_MODIFY(26)
