Subject: [musl] sysconf(_SC_NPROCESSORS_CONF) broken.
Date: Wed, 27 Jul 2022 01:28:29 -0500 [thread overview]
Message-ID: <43e9ad2b-d53c-5fd5-0211-766f946c90f9@landley.net> (raw)
NPROCESSORS_CONF is supposed to show total processors, NPROCESSORS_ONLN shows
available processors using the tasket mask sched_getaffinity()).
Musl is (uniquely) using the getaffinity() version for both. Neither glibc nor
bionic have that bug.
Test: my laptop has 4 processors:
$ taskset 7 nproc
3
$ taskset 7 nproc --all
4
With musl, both show 3.
Rob
