For project submission and automatic grading, we are running a dedicated server at http://sys.snu.ac.kr. If you want to access the sys server outside of the SNU campus, please send a mail to the instructor. Project #6: Kernel threads A kernel thread is a thread that always runs in the kernel space. Modern operating systems heavily use kernel threads to perform a certain task asynchronously. Currently, xv6 does not support kernel threads, so it’s your task in this project to extend xv6 so that it can support the creation and termination of kernel threads.
