hello！
i am using gem5's KVM to accelerate my simulation, but in version 22.0, I
encountered the following issue:
**** REAL SIMULATION ****
build/ARM/cpu/kvm/base.cc:150: info: KVM: Coalesced MMIO disabled by config.
build/ARM/dev/arm/energy_ctrl.cc:252: warn: Existing EnergyCtrl, but no enabled
DVFSHandler found.
build/ARM/sim/simulate.cc:192: info: Entering event queue @ 0. Starting
simulation...
build/ARM/cpu/kvm/base.cc:863: panic: KVM: Failed to set register
(0x6030000000100042) value (errno: 22)
I found a similar error in the email list before, but after checking the
patches, I realized that the patches were all there but the issue still wasn't
resolved.
After that, I switched the gem5 version to 20.1.0.5, but after running it, the
gem5's output remained stuck, and there was no output in m5term.
Here is my command line:
sudo ./build/ARM/gem5.opt ./configs/example/fs.py
--disk=/home/lyq/gem5/benchmark/itecgo/itecgo/expand-aarch64-ubuntu-trusty-headless.img
--kernel=/home/lyq/gem5/benchmark/itecgo/itecgo/vmlinux.euler --mem-size=12GB
--bootloader=/home/lyq/gem5/benchmark/itecgo/boot.arm64
--script=/home/lyq/gem5/benchmark/RCS/403.gcc.rcS --caches
--cpu-type=ArmV8KvmCPU
Is there anything I should check? I can provide more information if needed.
Thank you for any help!
mike
