  Ideally we'd see that branch figure out how to incorporate some of these ideas. I haven't done an analysis to explore. The article mentions one sample eBPF scheduler that does some cgroup work, but I haven't looked deeper.

• Testing against upstream kernel

  Is rebasing the sched_ext tree on top of upstream kernel the best method for testing against an upstream baseline? I thought I'd start testing by running a performance comparison between the current release kernel (6.3) and sched_ext with no special scheduling active to verify my assumption that there will be no perf delta without a special scheduler active. I rebased https://github.com/sched-ext/sched_ext/commit/82f404e53de0ac00040bccf2f7719159c25d4a11 on https://github.com/torvalds/linux/commit/457391b0380335d5e9a5babdec90ac53928b23b4 with no significant conflicts (just one documentation conflict), but I'm encountering the following error during build, which makes me uncertain that the rebase was clean:

• Suggestion for Linux games that are CPU bound, and/or a call for participation in scheduling experiments

  Indeed -- I'm already getting a ~2-3% win over CFS on Factorio using the scx_atropos and scx_example_simple schedulers from https://github.com/sched-ext/sched_ext/tree/sched_ext/tools/sched_ext, without any attempt to tune.

• Would anyone be willing to share a large saved-game file so I can experiment with optimizing Satisfactory using different scheduling policies on Linux?
