I had previously documented on README 10 minutes at: 2eff007f7c3458be240c673c32bb33892a45d3a0 found with `git log` search for `10 minutes`, to be confirmed and bisected. We have a fixed kernel config for gem5, so the only two variables are the Linux kernel version, and the gem5 version. One methodology problem is that some gem5 and QEMU were run with different kernel configs, due to <>. This could have been improved if we normalized by instruction counts, but to do that we would have to enable tracing which makes QEMU run much slower.
