Problems solved by technology

For each interrupt event, the Linux kernel needs a certain processing time; for a large number of interrupt events, the processing time required by the Linux kernel cannot be ignored, which directly leads to the delay of application response, which will bring a negative impact on user experience. come to noticeable impact

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] The overall structure diagram of the TV terminal operating system is as follows: figure 1 shown. The application is interpreted and executed through the execution engine. The execution engine can access the local capabilities of the terminal through the functional components, and can also access the kernel driver and system services through the standard library. The management and scheduling of each application is the responsibility of the system management framework, so the state of the application is also maintained by the system management framework.

[0015] After the user chooses to run an application, the system management framework will select a suitable execution engine for the application, start the execution engine, and then the application will start running. At this point, the application is in the "foreground running sta...

Abstract

The invention relates to a dynamic adjusting method of a kernel module driven by application. The method adjusts loaded kernel drive and system service into a working mode and a free mode or uninstalls the loaded kernel drive and the system service according to operation states. Priority of hardware interruption of various hardware devices of a television terminal is determined according to application priority, and interruption with high priority is processed preferentially.

Description

technical field [0001] The invention relates to a dynamic adjustment technology of a kernel module of an operating system of a television terminal, in particular to a dynamic adjustment method of a kernel module driven by an application. Background technique [0002] Currently, in the operating system of a TV terminal, it is a trend for multiple applications to run simultaneously. When the application is running, it involves the operation of related kernel drivers and system services, and the operation of kernel drivers and system services will consume certain resources. Compared with running a single application, the resources consumed by running multiple applications at the same time are much higher. Therefore, reducing the resource consumption of the kernel as much as possible can better support multiple applications running at the same time. In addition, for the sake of reducing resource consumption, general kernel drivers and system services are not loaded when the sy...
