Hi Junaid, I think you’ve manage to confuse the instruction set and the CPU model. To run with KVM, you need to specify the ArmKvmCPU as the CPU type. Needless to say, this means you need to build and run on an ARM host.

I tried to compare ARM KVM (--arm-iset=aarch64) and ARM (--arm-iset=arm). I used simple for loops (in millions) doing integer instructions. But the result of both --arm-iset=aarch64 and arm were similar with no significant performance gain. The instructions I used to emulate the full system are, build/ARM/gem5.fast configs/example/fs.py --disk-image=/home/junaid/gem5/full_system_images/disks/aarch64-ubuntu-trusty-headless.img --machine-type=VExpress_EMM64 --arm-iset=arm AND build/ARM/gem5.fast configs/example/fs.py --disk-image=/home/junaid/gem5/full_system_images/disks/aarch64-ubuntu-trusty-headless.img --machine-type=VExpress_EMM64 --arm-iset=aarch64 Is the ARM-KVM support still in process? Or did I miss something? -- Junaid Shuja WHA130039 PhD Student, FSKTM University of Malaya -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
