Hi all,
I have built my project on top of another project that used an older version of
gem5 between 2018 and 2019—the previous project implemented most of the stuff I
needed to do, which made my job easier.
I am now trying to run the project in FS mode to get its performance but, I am
having issues. So, the error is mainly a kernel panic error.
At first, I thought it was a disk image issue, but I ran it with the latest
unedited gem5, and it worked, but an older unedited gem5 version (from 2018 )
did not work. It also threw a kernel panic.
I have attached the Log for running FS. Does anyone have any ideas?
kernel: Linux version 4.19.83
run command: build/X86_MESI_Two_Level/gem5.opt configs/example/fs.py
--cpu-type=AtomicSimpleCPU --cpu-clock 2GHz --sys-clock 2GHz --l1d_size 32kB
--l1d_assoc 8 --l1i_size 32kB --l1d_assoc 8 --l2_size 2MB --l2_assoc 16
--l2cache --caches
since it's an older version of gem5, I used the M5_PATH to point to my disk
image and kernel
