My name is Piyush Mishra and I am an undergraduate student pursuing Bachelor's of Technology in Computer Science and Engineering from Bundelkhand University Jhansi, Uttar Pradesh, India. I have been working on android development and practicing open source since two years. I enrolled in Linux Foundation Kernel bug fixing project fall unpaid 2022 as Linux kernel mentee in the mentorship of Shuah Khan in order to increase my skill set and collect the knowledge and information of how the Linux kernel and Linux operating system works at architectural levels. Being working on the project as it is linux kernel debugging and it always starts with building and booting the kernel then comes the stack traces and events of a kernel. I came across decoding stack traces and kernel events. Rather than just simple bare metal its a procedure of virtualization where QEMU and GDB plays a vital role. Now I have been provided with a chance to submit a talk in Linux Mentorship showcase 2023 CFP I would like to share my experiences with USB and PCI devices.
