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

2018-06-01 Thread prakhar gurawa
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.

[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

This is not required, the best thing to do is to find what is the proper compatible cross compiler for the image: https://stackoverflow.com/questions/31929092/trying-to-run-a-cross-compiled-executable-on-target-device-fails-with-no-such-f/49993116#49993116 On Fri, Jun 1, 2018 at 6:34 AM, Tung

Hi, The important line is this one: / tmp / script: line 3: cd: / home / root / parsec: No such file or directory No way you can get the binary running if you cannot cd to the directory where the binary is located. That has no relation with how the binary was compiled. My intuition is that

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

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 (

hi all, I need to do an analysis on the change of time of simulation of a parsec 3.0 application (ex: blackscholes) in gem5 ,armv8 big.LITTLE mode , and I do not know the statistics (the instructions of file stats.txt) which are responsbales on the change of execution time (for example the
