Re: [gem5-users] gem5 FS mode and threads

[tod]

Hi Ali, I have dig into the source code checked every appearance of "enable_context_switch_stats_dump" and "enableContextSwitchStatsDump" and found the only place where i could toggle it was:  enable_context_switch_stats_dump = Param.Bool(True, "enable stats/task info dumping at context switch boundaries") in ArmSystem.py.  After doing this as shown above, in the config.ini file I still get this as : enable_context_switch_stats_dump=false. Can you please guide me about this? 2ndly, It would be so nice of you, If you kindly give me the steps of applying the given patch to my disk image "linux-arm-ael.img" file? lastly, will the output of my interest be in system.tasks.txt in the output directory? as it say here: http://gem5.org/Streamline ??? do i need to use any trace/debug flag for it? Thank you Ali for your response. It was really useful.

To get the vales you mentioned the simulator needs to know where to look for them, so you need to add some symbols to a newly compiled version of the kernel. Something like: http://repo.gem5.org/linux-patches/file/0ab58d9bd9a5/m5/m5struct.diff Ali On Apr 29, 2013, at 6:58 AM, tod <saril...@hanmail.net> wrote: Hi, More specifically, I am considering ARM and have the following questions: How to dump stats at context switches? I know it is something about callback for __switch_to(), but how and what exactly? How to dump process info (pid, tgid, task name, cpu id, etc.) at context switches ?

You can have gem5 create an ever on linux's __switch_to function and see what thread is running on which core by inspecting some kernel data structures. This is done for Alpha and for ARM.
