Hi Zeus,<br><br> I don’t know if it will help you, but you will find attached a chapter of our internal GEM5 tutorial (thanks Samuel for the help!) where I explain (some steps) how to use GEM5 with Barrelfish.<br><br> As Samuel said, this is an old version and he will launch a public release soon, but maybe this version <span id="result_box" class="" lang="en"><span class="hps">is</span> OK<span class="hps"> for what</span> <span class="hps">you want to do</span><span class="">.</span></span><br>

</div>As you 've probably seen already, we did make a public release, and as<br>
Samuel suggested, you should be able to find gem5_patches.patch in the<br>
current tree. I am not sure if gem5 on ARM works without problems for the<br>
current tip, but if there are problems they should be relatively easy to<br>
fix.<br>
<br>
