[gem5-users] Cacheline status throughout hierarchy
Hi all, I'm looking for a way to count the total number of dirty/clean blocks within the cache hierarchy to get an overall ratio from each cache simulated. So far I haven't had much luck in finding a straightforward way to do this other than running through the cache/base.cc file and manually looking for when a write or evict is issued. Any help would be appreciated!

[gem5-users] Re: How to modify the gem5 simulator code?
Hi, The files you want to look at for the memory access are src/mem/ dram_ctrl.cc/.hh and src/mem/DRAMCtrl.py for issuing requests from the memory controller. The memory access itself is performed in DRAMCtrl::accessAndRespond, with a call to access() which is defined in src/mem/abstract_mem.cc. This may have changed with recent gem5 updates but I don't think there is a field to identify the requesting core so you can differentiate between them, but perhaps adding a field in the packet class definition and assigning the threadID would help you do that.

[gem5-users] Benchmark terminating early
Hello all, I'm running a single core X86 o3 sim with SPEC2006 benchmarks, and have run into a scenario where some of the benchmarks are terminating early. Using the "DRAM" debug flag, I see this message upon termination: Exiting @ tick 67067500 because exiting with last active thread context 67067500: system.mem_ctrls_0: Computing stats due to a dump callback 67067500: system.mem_ctrls_1: Computing stats due to a dump callback Does anyone know of any way to properly debug the root cause of this issue? I have also used the Exec and ExecAll flags, but not much more information was provided. Thank you, - Alex ___ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s
[gem5-users] Re: Adding new source files
Hi Francisco,
Thanks for the quick reply! Yes I did; the .cc/.hh files are present and
are in the same directory. I've also realized something else: the file I'm
creating should reside in X86/mem/ (since that's where the .cc/.hh files
reside and the SConscript in that directory was updated), while SCons is
failing and stating that the file can't be found in the X86/sim directory.

[gem5-users] Adding new source files
Hi all,
I'm trying to understand how to add source files to the gem5 project
without the need to create a SimObject. I've added `Source('myFile.cc')`
into the respective SConscript file, but when I try to build I get this
message:
scons: *** [build/X86/sim/myFile.o] Source `build/X86/sim/myFile.cc'
not found, needed by target `build/X86/sim/myFile.o'.
scons: building terminated because of errors.
This is a very rookie question, but guidance would be appreciated!
