SubjectRe: [PATCH] sched: Enable arch-specific asym packing option in sched domain

This would seem to be to be a different problem. I don't think the
packing mechanism is what you want.

Shouldn't you be increasing the CPU power of this core, so that all
tasks get a fair go on this core? Otherwise you're breaking the
fundamental concept of a completely fair scheduler.

Using this packing mechanism you won't get this. Any task that lands on
core 0 will get an unfair amount of computation power, compared to tasks
that landed on core 1.
