Problems solved by technology

[0006] In the traditional method, the decompression process of the Linux kernel is completely performed by the CPU. Due to the large amount of data calculation, it is time-consuming; in addition, the relocation of the kernel requires data copying, which will also consume a certain amount of time.

Abstract

The invention relates to a Linux system starting acceleration method and device and a readable medium, and the method comprises the steps: executing the compiling of a Linux kernel, obtaining a compressed Linux kernel, and enabling the compressed Linux kernel to comprise a self-decompression program and a Linux kernel package; programming the physical information of the compressed Linux kernel and the physical information of the Linux kernel compressed package to a storage medium; reading the compressed Linux kernel from the storage medium, and executing decompression through a self-decompression program; and skipping the decompressed compressed Linux kernel to a kernel interface and running the kernel interface. The method has the beneficial effects that when the compressed version Linux kernel is obtained, the non-overlapped position is directly read, so that the copying operation of kernel relocation is avoided; and secondly, the self-decompression process is accelerated through a hardware engine, so that the decompression efficiency is greatly improved. And after the decompression is completed, the Linux kernel is skipped to directly run, so that the starting speed of the Linux system is increased.

Description

Technical field [0001] The present invention relates to the field of computer operating systems, and more particularly to a Linux system boot acceleration method, device, and readable storage medium. Background technique [0002] Linux operating systems are widely used in various embedded applications, such as intelligent hardware, driving monitoring, and more. In these products, the start speed is an important indicator that affects the overall user experience. How to improve the starting speed of the product is a problem that each chip and program manufacturers need to solve. [0003] refer to figure 1 In the traditional method, the steps associated with Linux are divided into: compilation phase, the burn phase, the Uboot phase, the Linux run phase, where the compile stage is compressed, generates a compressed version of the Linux kernel; the burn-in phase will be compressed The Linux kernel burn to the storage medium; the UBOOT phase reads the compressed version of the Linux k...
