Subject: [RFC PATCH 0/2] sched/topology: Get rid of overlapping groups
Date: Wed, 3 Feb 2021 15:54:29 +0000 [thread overview]
Message-ID: <20210203155432.10293-1-valentin.schneider@arm.com> (raw)
Hi folks,
My keyboard still hasn't been taken away from me, so I went down and did what I
was rambling about in [1].
The preemptive degeneration check is the worst wart, but I think I'll have to
sleep on it before I can figure out a better way.
Something tells me the increase in group numbers isn't going to make me any
friends, so I've included 3/2 which is Barry's approach (with the subset check
condensed in a single spot).
Cheers,
Valentin
