Hello, I'm using the x86-spec-cpu2017-benchmarks.py config file to run spec2017 benchmarks. I followed this tutorial https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/spec-2017/ for building the spec disk image.
Currently, the linux booting is done with KVM CPU and the rest of the simulation is done with the TIMING CPU. However, after booting linux, there are lots of steps before the benchmark actually gets to run. For example, here are the logs in my board.pc.com_1.device file after booting linux: "Welcome to Ubuntu 18.04.2 LTS (GNU/Linux 4.19.83 x86_64) * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage New release '20.04.6 LTS' available.

Is there any way to run everything on the KVM CPU before running the actual benchmark application? Thanks, Fayza.
