AI Technical Summary

Technical Problem

Without root privileges, performance analysis tools cannot access the kernel symbol table in the kernel space, making it impossible to analyze and debug operating system performance.

Method used

By reading the address of the first kernel function in the user space of the electronic device, the second kernel symbol table is calculated, and performance analysis tools are used to collect and parse the data, enabling the analysis and debugging of operating system performance without root privileges.

Benefits of technology

Without root privileges, data can be parsed using performance analysis tools and the kernel symbol table in user space, enabling the analysis and debugging of operating system performance and reducing the operational complexity for testers.
