Subject: Re: [RFC PATCH RESEND 05/10] sched/fair: Introduce select_task_rq_fair_thin() to select rq when LB_PROMOTE
Date: Wed, 16 Sep 2026 00:43:48 +0300	[thread overview]
Message-ID: <20260915214348.22220-1-kayracizmeci@gmail.com> (raw)

Hello Xin and Vincent :>,

I already read Vincent's review, so I'll not repeat the same things on this one.

I just wanna ask, why we are dropping whole energy parts? And creating a function that
is connected to only one option?

You say this is for embedded systems too. Don't you think energy parts are important
on embedded systems?

I don't think saying that this is a 'optimization' is the true term. It's more of a trade-off
that can be good for some special use cases.



Sorry if I repeated anything, :>

Thanks,
Kayra
