Abstract: A computer-implemented system, computer-implemented method, and computer program product for facilitating in-kernel instrumentation of kernel-level processes are envisaged. The system, method, and computer program product implement the in-kernel instrumentation independent of the user space and without sharing any kernel-level processes-related information with the user space. A plurality of predetermined, customized eBPF maps are created and used to store information directed to kernel-level processes, including process ID, process namespace ID, process context, process parameters, and pointers directed to kernel-executable instrumentation-related directives.

Abstract: A method and an electronic device for outputting an audio signal in the electronic device is provided. The electronic device includes a first speaker, a second speaker, and an audio processor that creates, from an audio signal, a first frequency audio signal corresponding to a first frequency band by using a low pass filter, synthesizes the created first frequency audio signal and the audio signal to create a synthetic audio signal, creates, from the synthetic audio signal, a second frequency audio signal corresponding to a second frequency band by using a high pass filter, outputs the created second frequency audio signal through the first speaker, and outputs the created synthetic audio signal through the second speaker.
