[gem5-users] Simulation halts after calling pseudo instructions

[Majid Jalili]

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
