Abstract

The embodiment of the invention discloses an interruption processing method and a device for network data. The method includes as follows: when a network interruption request is received, an interruption processing program is firstly executed; then a CPU group needed to participate in the interruption processing is confirmed; then each CPU in the CPU group is triggered for carrying out the interruption processing on the network data. According to the embodiment of the invention, the idle CPUs in a CPU operation system can be led to process an interruption response as well, thus solving the waste problem of system resources under a multi-core platform; besides, processing the interruption request by a plurality of CPUs is capable of extensively improving the property of the CPUs to processthe network data and reducing the phenomenon of packet losing.

Description

technical field [0001] The invention relates to the field of computer systems, in particular to a network data interruption processing method and device. Background technique [0002] In the operating system, for example, Linux system, embedded system, etc., when the central processing unit CPU is running the program normally, due to the occurrence of an internal or external unexpected event, the CPU suspends the currently running program and turns to execute the corresponding program. A handler to handle the unexpected event, and then return to the suspended currently running program to continue execution. This process is an interrupt in a computer system. Interrupts can be divided into: peripheral interrupts, traps and exceptions, etc. Peripheral interrupts mainly refer to device interrupts outside the CPU, traps are mainly interrupts caused by special instructions (such as INT), and exceptions are exceptions that occur when the CPU is running Or errors; traps and except...
