return 0;

Hi, In my code, I am calling m5_switch_cpu to trigger cpu change. However, as soon as it is called my simulation process goes to the S state, and is put to sleep. Here is my code: #include <iostream> #include "gem5/m5ops.h" using namespace std; int main() { cout<<"Hi"<<endl; m5_switch_cpu(); cout<<"Bye"<<endl; m5_exit(0); return 0; } And below is the ps a nad strace output ---ps a----- PID TTY STAT TIME COMMAND 2941 ttyS0 Ss 0:00 /bin/login -f 2959 tty1 Ss 0:00 /bin/login -f 3199 tty1 S+ 0:00 -bash 3251 ttyS0 S+ 0:00 -bash 3981 pts/0 Ss 0:00 -bash 8488 pts/2 Ss 0:01 -bash 31779 pts/1 Ss 0:01 -bash 35156 pts/2 S+ 0:00 sudo /home/cc/borrow//build/X86/gem5.opt -d test /home/cc/borrow//configs/example/fs.py --caches --kernel /home/cc/disks/binaries/vmlinux-5.4.49 --disk-image /home 35157 pts/2 Sl+ 0:38 /home/cc/borrow//build/X86/gem5.opt -d test /home/cc/borrow//configs/example/fs.py --caches --kernel /home/cc/disks/binaries/vmlinux-5.4.49 --disk-image /home/cc/d 35164 pts/0 S+ 0:00 telnet localhost 3456 35176 pts/1 R+ 0:00 ps a ------------------- Strace cc@mm:~/disks/disks$ sudo strace -p 35157 strace: Process 35157 attached futex(0x5648516cf894, FUTEX_WAIT_PRIVATE, 12, NULL^Cstrace: Process 35157 detached <detached ...>
