Re: [PATCH] sched/fair: avoid creating misfits during cache-aware balancing

[KobaK]

Hi Tim,

Thanks for the cache-aware load-balancing misfit patch. The tradeoff
you describe (LLC locality vs capacity loss) is clear.

I have been trying to understand how this showed up in testing. The
cover explains the failure mode, but I did not find a note on the
observation method.

Would you mind sharing how you tested and observed it? In particular:
which hybrid generation, what workload, and whether you used
schedstat lb_imbalance_misfit or another signal.

Thanks,
Koba
