 Posted: Thu Apr 22, 2021 5:54 pm Post subject: lm-sensors reported core id numbers |
 |
|
Some of the core ID numbers given by running sensors (lm-sensors-3.6.0) are not all sequential and some of core ID numbers are greater than the number of cores on my CPU. I see this issue on both of my Gentoo systems.
For example, on this system which is running an Intel(R) Xeon(R) Gold 6136 CPU @ 3.00GHz with 12 cores (24 threads) running sensors gives:
| Code: | $sensors
coretemp-isa-0000
Adapter: ISA adapter
Package id 0: +25.0°C (high = +93.0°C, crit = +103.0°C)
Core 0: +25.0°C (high = +93.0°C, crit = +103.0°C)
Core 1: +24.0°C (high = +93.0°C, crit = +103.0°C)
Core 2: +23.0°C (high = +93.0°C, crit = +103.0°C)
Core 3: +24.0°C (high = +93.0°C, crit = +103.0°C)
Core 4: +24.0°C (high = +93.0°C, crit = +103.0°C)
Core 9: +24.0°C (high = +93.0°C, crit = +103.0°C)
Core 10: +24.0°C (high = +93.0°C, crit = +103.0°C)
Core 16: +25.0°C (high = +93.0°C, crit = +103.0°C)
Core 18: +23.0°C (high = +93.0°C, crit = +103.0°C)
Core 19: +24.0°C (high = +93.0°C, crit = +103.0°C)
Core 25: +23.0°C (high = +93.0°C, crit = +103.0°C)
Core 26: +24.0°C (high = +93.0°C, crit = +103.0°C) |
I re-installed lm-sensors today after reading through https://wiki.gentoo.org/wiki/Lm_sensors and still have the issue. From eix, my current lm-sensors install:
| Code: | | Installed versions: 3.6.0(0/5.0.0)(09:36:18 AM 04/22/2021)(contrib sensord static-libs ABI_MIPS="-n32 -n64 -o32" ABI_S390="-32 -64" ABI_X86="32 64 -x32" KERNEL="linux") |
sensors-detect tells me I should be (and am) using coretemp:
| Code: | #----cut here----
# Generated by sensors-detect on Thu Apr 22 09:42:06 2021
coretemp
#----cut here---- |
Part of lsmod:
| Code: | coretemp 16384 0
hwmon 20480 1 coretemp |
Any idea why the core ids are not all sequential???? (This seems to mess up bpytop.)
I note that i7z does not have this issue:

cpuinfo might be wrong if cpufreq is enabled. To guess correctly try estimating via tsc
