[gem5-users] SPEC2017 FS Simulation - Using KVM up to the point when the benchmarks finally run

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

[gem5-users] SPEC2017 Calculating CPI

Hi, I'm running SPEC2017 benchmark in full-system mode using the configs/example/gem5_library/x86-spec-cpu2017-benchmarks.py config file. In the outputs m5/stats.txt, there's no system.cpu.cpi metric mentioned. So, to calculate the CPI, I tried dividing board.processor.switch0.core.numCycles by

[gem5-users] How to use the argument warmup-insts?

Hi, could anyone tell me how to use the option warm-up insts? I found this option in configs/common/Options.py line 612 parser.add_argument( "-W", "--warmup-insts", action="store", type=int, default=None, help="Warmup period in total instructions (requires --standard-switch)", ) But I'm not sure

[gem5-users] Setting the maxinsts after warm-up period for running SPEC2017 in full-system mode

Hello, Could anyone tell me how to set the max number of instructions to run after the warm-up period? I'm not sure how to make the relevant change in the x86-spec-cpu2017-benchmarks.py file. Or, is it possible to do this with command-line arguments? Thanks, Farbin.

[gem5-users] SPEC2017 - Most of the metrics in m5.out/stats.txt are 0 or undefined

Hi, I'm trying to run spec2017 benchmark in full system mode with gem5. I followed this tutorial to build the disk image file for spec https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/spec-2017/ . The only difference with the tutorial is that I have spec version, 1.1.9
