Hi Xiaoyu, I had to do something similar a while back on ARM. From the looks of arch/x86/stacktrace.hh, I think it will work the same for your case. There was a thread that had an example on how to get the pid, but I'm not seeing it in this forum.
ThreadContext *tc = system()->getThreadContext(pkt->req->threadId()); // use Packet object, Request object Addr stackPtr = tc->readIntReg(INTREG_SP_SVC); // INTREG_SP_SVC is the SP register for ARM ProcessInfo procInfo = new ProcessInfo(tc); // make sure to include stacktrace.hh int pid = procInfo->pid(stackPtr); delete procInfo; Hopefully this works for you, or at least helps you in some way.
