Hi, I'm new here gem5.
I want to trace DRAM access, but I'm not familiar with gem5 and dramsim3.
I don't know how to use gem5 and dramsim3 together.
So I will make a trace file by gem5, and use it for dramsim input.
These are my questions.
Q1. How can I get a DRAM trace file?

It's normal for valgrind to slow things down a lot. One thing you can do to
at least improve the quality of the errors you get is to use the
suppressions file in util/valgrind-suppressions. The python interpreter
does a lot of things which upset valgrind, and this tells valgrind mostly
to ignore th
Hi Sindhuja,
Yes, there is an expectation that valgrind causes a slowdown. Let me give
you a couple of suggestions.
1. Make sure you compile without tcmalloc (e.g., scons
build//gem5.opt --without-tcmalloc). Using tcmalloc will make
valgrind miss all allocations.
2. Use the suppressions file in u
Hi Community,
I ran into bad_alloc issues in GEM5 with the full system simulation of SPEC
2006 benchmarks.
Suspecting a memory leak, I wanted to use valgrind to understand better.
Without valgrind option, it takes less than 10 minutes for kernel to boot and
also run the 400.perlbench/attrs bench
What is your linux version, and gem5 version, and where did you download
gem5 from?

Hi all,
This is a very basic and perhaps silly question. I’m trying to take checkpoints
in a gem5 program so that I can debug a particular segment of the execution
more efficiently, but it seems that the flag seems to pause the execution of
the environment and not actually take any checkpoints.
One more time: this is not a dependency error! Read carefully the lines about
being not found: this is written "WARNING". This is an OPTIONAL feature
resulting in a non fatal warning if not present.
Your problem is a couple of lines above: "fatal error: ld terminated with
signal 9 [Killed]". A
