Hi everyone, I'm trying to run the latest version of Gem5 under X86 and it segfaults at the following line:
build/X86/cpu/o3/fetch.cc:139 > decoder[tid] = params.decoder[tid]; gdb says params.decoder is a "vector of length 0". Looks like it has not been initialized. Any idea how to correctly initialize this? Here is my command line: ./build/X86/gem5.opt -r -d sim_output/stride/benchmark configs/example/fs.py --mem-size=16GB -n 4 -r 1 --disk-image=/hdd0/newCPTs/ubuntu-server-16.04.6.img --checkpoint-dir= /hdd0/newCPTs/bench_1 --cpu-type=DerivO3CPU --rel-max-tick=2000000000 --l2-hwp-type=StridePrefetcher --caches --l2cache --kernel=vmlinux-5.4.49 I have also tried assigning decoder[tid] to a new TheISA::Decoder() object in fetch.cc like it used to be in older versions but this leads to build issues. To reiterate, I have not modified a single line of code. I was able to take checkpoints under KVM mode successfully, however. Thank you, Gagan
