Hello,
My aim is to copy the context of a thread to another thread which runs
on different cpu. According to the definition of takeOverFrom() in
gem5/src/cpu/thread_context.cc, we can copy thread contexts:
/**
* Copy state between thread contexts in preparation for CPU handover.
*
* @note This method modifies the old thread contexts as well as the
* new thread context. The old thread context will have its quiesce
* event descheduled if it is scheduled and its status set to halted.
*
* @param new_tc Destination ThreadContext.
* @param old_tc Source ThreadContext.
*/void takeOverFrom(ThreadContext &new_tc, ThreadContext &old_tc);
However, after I used takeOverFrom() function, the newly copied thread
(other_tc) cannot be activated and it gives an error in
activateContext() function.
tc->suspend();
tc->pcState(tc->nextInstAddr());
other_tc->takeOverFrom(tc);
Am I doing something wrong? Can I copy the content of a thread to
another one like that?
