Hi Gogineni. By adding extra entries to x86's system call table, all you did was tell gem5 those system calls existed so that it could print a more informative message about them not being implemented. Your second change, when you added getrandomFunc to the getrandom entry, would work, except you have to actually implement a getrandomFunc. You can look at the implementations in src/sim/syscall_emul.hh and src/sim/syscall_emul.cc to get an idea how to do that.
You are welcome to try to run the python interpreter in SE mode, and you might get it to work. The python interpreter is large and complex though, and you might end up spending a lot of time and effort trying to implement missing system calls, etc, and it may not be worth the trouble. You might want to try running it in FS mode instead, where the simulated OS handles all the system calls, etc, like it would on a real machine.
