US 2026/0081876 A1 · DATA PROCESSING METHOD, NETWORK INTERFACE CARD, ELECTRONIC DEVICE, AND STORAGE MEDIUM

Abstract

A data processing method, a network interface card, an electronic device, and a storage medium. The method includes: determining a target dispatch queue to be dispatched from a host memory in response to a doorbell signal sent by a target host, where the doorbell signal indicates that there is a target message to be sent; determining a current target dispatch state of the target dispatch queue, where the target dispatch state is obtained based on an activity and a credit value corresponding to the target work queue element; determining whether a dispatch mechanism corresponding to the target dispatch queue is valid based on the target dispatch state, where the dispatch mechanism indicates whether the target dispatch queue is allowed to be dispatched; and performing a dispatch operation on the target work queue element and the target message in response to the dispatch mechanism being valid.

Dependent claims

A data processing method, comprising:

determining, in response to a doorbell signal sent by a target host, a target dispatch queue to be dispatched from a host memory, wherein the doorbell signal indicates that there is a target message to be sent in at least one target work queue element in the target dispatch queue;
determining a current target dispatch state of the target dispatch queue, wherein the target dispatch state is obtained based on an activity and a credit value corresponding to the target work queue element;
determining, based on the target dispatch state, whether a dispatch mechanism corresponding to the target dispatch queue is valid, wherein the dispatch mechanism indicates whether the target dispatch queue is allowed to be dispatched;
and
performing a dispatch operation on the target work queue element and the target message in response to the dispatch mechanism being valid.

A network interface card, comprising:

a direct memory access engine module and a transmission module;
the direct memory access engine module is configured to determine, in response to a doorbell signal sent by a target host, a target dispatch queue to be dispatched from a host memory, wherein the doorbell signal indicates that there is a target message to be sent in at least one target work queue element in the target dispatch queue;
determine a current target dispatch state of the target dispatch queue, wherein the target dispatch state is obtained based on an activity and a credit value corresponding to the target work queue element;
and determine, based on the target dispatch state, whether a dispatch mechanism corresponding to the target dispatch queue is valid, wherein the dispatch mechanism indicates whether the target dispatch queue is allowed to be dispatched;
and
the transmission module is configured to perform a dispatch operation on the target work queue element and the target message in response to the dispatch mechanism being valid.
