Hi, I am working on x86 Full System simulation. My goal is to get the process name (eg. /root/my_prog.elf) that runs within the simulated image for the current instruction being simulated. Also, I would like to get the PID as well. I tried the following under the arch/x86/TLB.cc:: translate() Process *processPtr= tc->getProcessPtr(); print (processPtr->progName() and processPtr->pid()) However, processPtr is always null, which invokes a segfault whenever I try to access any of the member functions. The same lines are used within this function, however, they are only invoked in case of SysCall Emulation mode NOT FullSystem. I came by this VERY old thread on gem5 mailing list: https://www.mail-archive.com/gem5-users@gem5.org/msg08815.html , but I could not find any implementation of the ProcessInfo class. So, is there a way that I can print the progName and the PID of the instruction in x86 FullSystem mode? Thanks, ~Abdelrahman -- *Best,Abdelrahman Hussein*
