Hi Yara, I'm not very familiar with the power modeling in gem5, but this seems like you found and then fixed a bug! We would really appreciate it if you contributed this change to the mainline. You can find a description of how to do this in the CONTRIBUTING document (

I think I found a solution to this problem. It required changing something in the src file gem5/src/sim/power/mathexpr_powermodel.cc. In the startup function the stats are being recorded from the statsList to the stats_map which will be used by the power model to find the corresponding value to

[gem5-users] Can we run memtestx86 on gem5 with dramsim2 memory?

2018-06-01 Thread prakhar gurawa
Is it possible to run memtestx86 on gem5. I have already attached dramsim2 as memory type. That's not the issue. Main priority is to run memtestx86 on gem5. Thanks in advance. ___ gem5-users mailing list gem5-users@gem5.org

[gem5-users] How is addresses mapped between gem5 and dramsim2?

Sir/Ma'am, I have successfully integrated dramsim2 and gem5. Now I want to learn how memory/addresses are mapped between gem5 os( disk image in fs mode) and dramsim2 (memory used).Because addresses printed by dramsim2 in file memory controller. Cpp is not in league of that in OS by gem5 fs mode.
