Hello We booted ubuntu using AtomicCPU and wanted to switch cpu cores. Different options we tried but both resulted in different errors
1. we set --cpu-type = <new core type> and --restore-cpu-type = AtomicSimpleCPU, we tried the following two options a. ./build/X86/gem5.opt configs/example/fs.py --disk-image=ubuntu_base_v1.1.img --kernel=vmlinux-5.2.3 --cpu-type=DerivO3CPU --restore-with-cpu=AtomicSimpleCPU --caches --l2cache --mem-size=8192MB -r 1 We got a panic: StaticInst::branchTarget() called on instruction that is not a PC-relative branch Alternately, b. ./build/X86/gem5.opt configs/example/fs.py --disk-image=ubuntu_base_v1.1.img --kernel=vmlinux-5.2.3 --cpu-type=X86KvmCPU --restore-with-cpu=AtomicSimpleCPU --caches --l2cache --mem-size=8192MB -r 1 We got a gem5.opt: build/X86/sim/eventq_impl.hh:44: void EventQueue::schedule(Event*, Tick, bool): Assertion `when >= getCurTick()' failed. Thanks Niranjan
