What does command "b" do? 2. What does command "c" do? 3. What do you see by executing the commends (b, c, c, c)? Why do you see that? REFERENCES It is possible to use GDB with xv6. To do this instead of running make qemu or make qemu- nox, run make qemu-gdb or make qemu-nox-gdb respectively. Then, in another window, run gdb from the xv6 directory, and then run the command source .gdbinit within GDB. Then, within GDB, you can set breakpoints with break function name (and various similar commands) and start execution of the OS with continue.
