Hello, it would help if you could run it with gdb, place a breakpoint in BaseKVMCPU::setOneReg and tell us which register gem5 is trying to set
Kind Regards Giacomo From: 何雨彬 via gem5-users <gem5-users@gem5.org> Date: Tuesday, 15 August 2023 at 07:00 To: gem5 <gem5-users@gem5.org> Cc: 何雨彬 <bjutheyu...@emails.bjut.edu.cn> Subject: [gem5-users] boot arm with kvm 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 IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
