Hi, I want to use DRAMSim2+GEM5, and the patch of Xiangyu Dong is used.
Dong only supplies the se_dramsim2.py, but I want to use the FS mode.
I modified the fs.py, only adding one sentence below
test_sys.physmem = DRAMMemory(range=AddrRange("512MB"))
the following error occured.
xniu@hec-53:~/gem5_parsec1/gem5$ ./build/ALPHA_FS/m5.opt
