Hi All:
I use gem5 20.1 ,and bootup with fs.py and dramsim3 model,but some
error printed.
As I know, gem5 20.1 new feature has departed the medium interface
from memctrl, however, these modifications are only for the DRAM model inside
gem5, I think external memory Dramsim3 and NVmain do not adapt to these changes.
my script:
./build/ARM/gem5.opt --debug-flags=DRAM -d ./m5out configs/example/fs.py
--cpu-type=O3_ARM_v7a_3 --kernel=vmlinux -n 2 --machine-type=VExpress_GEM5_V1
--disk-image=aarch64-ubuntu-trusty-headless.img --bootloader
./system/arm/bootloader/arm64/boot.arm64 --caches --l2cache
--checkpoint-dir=./m5out --mem-type=DRAMsim3 --mem-size=2GB
Error:
