Performance Analysis of Process Using Loadable Kernel Module (LKM)

Performance analysis of a process plays a significant role in improving the overall efficiency of any system. Usually, this task is accomplished either by system level commands or user space applications, based on proc file system. These existing user space based mechanisms are limited in application and often fail to provide the required process specific data to user. In order to avoid this limitation, we have proposed a new linux kernel module(LKM) based approach, which can be potentially used to track any process specific data in real time. In this approach, the user does not require any separate tool but the kernel module to gather all essential information. Further, the competence of this module based technique can be enhanced by incorporating additional functionalities and thereby making it a full-fledged multiprocess abstraction layer to cater the needs of any high performance embedded platform.
