DRAMA code can not decode right row bit

[HugoXu]

Hi ,
I try to run DRAMA code, there is two issues :
The first one is it will not finished even I run it more than 12 hours.
The second one is that it is row bit mask is not right if it can be finished .
I am very familiar with Intel memory controller. So I know the row address mapping.
But the result is not right if they can decoded by DRAMA.

Hi,
Can you tell which system are you running on?
The DRAMA program does not return the row bits accurately. Some of the returned row addressing bits are instead bank addressing bits

Same issue here.
I‘m running DRAMA code on Intel Q370 system with Intel I7-8700 CPU, output nothing and not finished after more than 12hs.

The program should not take more than some minutes to terminate. If he takes too long means that he is not working properly and this is probably because of timing parameters issues. Can you run the program with the -o flag and run the histogram.py script on the output file? You should be able to retrieve a threshold value. You can post the picture or the output file to help us understand if this is the problem.

I run it in Intel coffee lake. coffee lake decode is also same.
One issue is that bank bit is very important for row hammer.
Because if you hit different bank , it means it is not active-perchange in current row.

Hi,
could you help to show me how to set the value of "g_mem_layout" according to the output file(access.csv) of drama?

access.zip

Thanks

I have trouble setting g_mem_layout as well. I managed to obtain the row mask, but I'm not sure how to fill in the AddrFns and the bank mask.
