Package: util-linux
Version: 2.20.1-4
Severity: normal
Dear Maintainer,
lscpu seems to miss reading about /sys/devices/system/cpu/cpu2/ and this causes
strange information in lscpu output, like 2
threads per core. Many sparc systems have sparse CPU numbering since the CPU
numbers come from hardware. This server (Sun E220R)
has CPU-s 0 and 2 present but lscpu only looks at 0:
mroos@e220r:~$ strace -e open /usr/bin/lscpu

open("/lib/sparc-linux-gnu/libc.so.6", O_RDONLY) = 3
