Message-ID: <45b369af-dd8a-0514-815d-3501b1377ad3@adit.fi> (raw)
Lenovo T580: i7-8550U
Debian Buster
Kernel 4.3.12 (static), .config:
----------------------------------
...
CONFIG_I2C_SMBUS=y
CONFIG_I2C_ALGOBIT=y
...
CONFIG_I2C_I801=y

I/O ports at efa0 [size2]
Kernel driver in use: i801_smbus
...
--------------------------------------------------------------
Only 4 core temps reported by sensors (/proc/cpuinfo shows all 8).
Senors report:

sensors-detect complains:
-------------------------------------------------
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-i801' for device 0000:00:1f.4: Sunrise Point-LP (PCH)
modprobe: FATAL: Module i2c-dev not found in directory /lib/modules/4.13.12
Failed to load module i2c-dev.
------------------------------------------------
Of course module can not be loaded in a static kernel. IMHO detection
should not depend on that.
Is this the reason for not showing any core temps under thinkpad-isa-0000?
Why only 4 under coretemp-isa-0000?
