missing sensors after kernel upgrade

colegu · 2022-04-14 12:31:48

after switching from default arch kernel to my new kernel (compiled from source) i'm not able to see the following ACPI sensor entries:

 
BAT0-acpi-0
Adapter: ACPI interface
in0:          12.55 V  
curr1:       1000.00 uA 
 
acpitz-acpi-0
Adapter: ACPI interface
temp1:        +54.5°C  (crit = +107.0°C)

does anyone know where are the relevant kernel options that i need to enable?
the following option is already configured CONFIG_ACPI_THERMAL=y, but it seems that it does not do the job..

at the moment i'm able to see only what
drivetemp-scsi-0-0, coretemp-isa-0000 and dell_smm-isa-0000 sensors are reporting

Is CONFIG_ACPI_BATTERY enabled?

seth · 2022-04-14 13:45:35

I'd compare "lsmod" for both kernels, you're perhaps lacking some vendor-specific ACPI module.
Also diff "zgrep -i acpi /proc/config.gz" for both kernels? CONFIG_ACPI_BATTERY?

grep-ing for acpi does not help, there's plenty of stuff there that doesn't look like it

You've no vendor specific ACPI module enabled, nor CONFIG_GPIO_ACPI nor CONFIG_ACPI_TABLE nor CONFIG_ACPI_PCI_SLOT nor CONFIG_INTEL_TH_ACPI …

i have no available options for GPIO_ACPI or ACPI_TABLE
also, under
ACPI (Advanced Configuration and Power Interface) Support --->
i see no vendor specific options, just generic entries

i'm giving another go with PCI_SLOT and INTEL_TH_ACPI options enabled.

 lsmod | grep intel_th
intel_th_sth           16384  0
intel_th_pti           16384  0
intel_th_pci           16384  0
intel_th_msu_sink      16384  0
intel_th_msu           28672  1 intel_th_msu_sink
intel_th_gth           16384  0
intel_th_acpi          16384  0

still no acpi entries in lmsensors..

What do you think eg. toshiba, system76 and thinkpad are?
Bus systems?

Again: check the lsmod of the regular kernel, compare it to your individual one and start filling the gaps (starting w/ the most suspicious ones)

you do not need to answer if there is nothing constructive to add this îs why i asked here to get an answer not just a wild goose chase like the Intel th thing that has nothing to do with the problem at hand. i have already compared the loaded modules between both kernels. not to mention that module names and config options are two separate things . finding the connection between them is quite elusive most of the time.

hw specific sensors already work. the generic acpi ones are failing

seth · 2022-04-14 19:43:39

The constructive addition is to look at which kernel modules you're missing.
If you want more constructive comments, you'll have to provide *some* information about the system and your custom kernel config.
Right now we're at "my somehow custom kernel does not really work on whatever hardware I might use why is that?"
Based on that *nobody* will be able to tell you anything more than where to look.

the generic acpi ones are failing

Ther thermal zone ACPI forwards a BIOS value, there's nothing "generic" about that. (Well, there probably should™ be…)
Sanity check: you do have CONFIG_THERMAL=y enabled, do you?

yes, CONFIG_THERMAL=y is enabled.

to enable temperature monitoring for the HDD i just enabled a config option that gives 'drivetem' module. this functions for several HDDs.
for system's specific drivers i enabled SENSORS_DELL_SMM, and other stuff (intel coretemp)

enabling acpi_power_meter module did not give the expected results, hence my original question. it most likely is a generic driver (similar to the drivetemp module) rather that something specific (dell_smm for that matter)

(last option seems to do absolutely nothing)

this is what i have so far under HW monitoring. most probably those ACPI settings are elsewhere (the linux kernel has it's ways to mix up similar things under different config locations)
and this is what i'm trying to find out

for system's specific drivers i enabled SENSORS_DELL_SMM

Not according to the config you posted…

DELL_WMI and DELL_SMBIOS could be relevant.
Did you meanwhile compare lsmod between the kernels?

this is the list of modules enabled in the default kernel and not in mine. (some of the options i've built in, like ext4, i915 and so on.
none of the above modules suggest that are responsible for the ACPI missing sensors..

intel_uncore ?

colegu · 2022-04-15 17:16:15

https://cateee.net/lkddb/web-lkddb/INTE … NTROL.html

sounds like is CPU related

seth · 2022-04-15 20:43:27

https://en.wikipedia.org/wiki/Uncore
I know what the uncore is - the idea is that it might indeed be relevant in this context (at least concerning the thermal zone)

colegu · 2022-04-16 05:52:03

$ modinfo intel_uncore

seems that i've already enabled that, but builtin.. still no ACPI sensors...

first part is the generic kernel, second is the one compiled by me.. now i have to figure out where to find those options

got rid of the errors with an extra kernel boot parameter. but no acpi sensors still .
seems that i'm missing the USB ACPI thing. but doubt that this will solve it.. will give it a go though

Maybe try

acpi_enforce_resources=lax

on your command line.

That was the only way I could get my sensors exposed (they are all thru a Super I/O chip).

nope, does not work with this boot option. i have to set it to no, otherwise i'm getting these errors
