ASUS B450 thermal sensors ITE IT8665E

[digidax]

Hi there,

I want to monitor the temperature and voltage of the mainboard.
sensors-detect says:

Driver `to-be-written':
* ISA bus, address 0x290
Chip `ITE IT8665E Super IO Sensors' (confidence: 9)

Note: there is no driver for ITE IT8665E Super IO Sensors yet.
Check https://hwmon.wiki.kernel.org/device_support_status for updates.

Is there a way to get working the ITE IT8665E ?

Thanks, Frank

unsupported, but maybe it works: https://zedt.eu/tech/linux/how-to-add-experimental-sensors-support-for-it8665e-in-centos/
CAUTION: use at your own risk

sadly some of those chips do not have a public data sheet, or its under nda, so there is no 'good' implementation

Thanks Dominik,
The git of a1wong doesn't support the IT8665E. But this https://github.com/frankcrawford/it87 has it included.
Cloning the git and making install was done successful, but can't load the module:

The new module is available:

# ls -l /lib/modules/5.4.106-1-pve/kernel/drivers/hwmon/it*
-rw-r--r-- 1 root root 679864 Apr 30 08:17 /lib/modules/5.4.106-1-pve/kernel/drivers/hwmon/it87.ko

root@pve4:~# modprobe it87
modprobe: ERROR: could not insert 'it87': Device or resource busy

checking loaded modules:

root@pve4:~# lsmod | grep it87

gives an empty result.

checking dmesg:

root@pve4:~# dmesg | grep it87
[  857.032545] it87: it87 driver version v1.0-54-gb159857
[  857.032644] it87: Found IT8665E chip at 0x290, revision 6
[  857.032712] it87: Beeping is supported

okay, but it87 seems to be loaded?

No voltage, Fan speed or mainbord temp probes are found.
Anyone an idea maybe?

you could try to set "acpi_enforce_resources=lax" as kernel boot parameter, this helps on some motherboards to get more sensors

Ok, done.

Test after update-grub

# cat /boot/grub/grub.cfg | grep "lax"
        linux   /ROOT/pve-1@/boot/vmlinuz-5.4.106-1-pve root=ZFS=rpool/ROOT/pve-1 ro root=ZFS=rpool/ROOT/pve-1 boot=zfs quiet acpi_enforce_resources=lax
                linux   /ROOT/pve-1@/boot/vmlinuz-5.4.106-1-pve root=ZFS=rpool/ROOT/pve-1 ro root=ZFS=rpool/ROOT/pve-1 boot=zfs quiet acpi_enforce_resources=lax
                linux   /ROOT/pve-1@/boot/vmlinuz-5.4.73-1-pve root=ZFS=rpool/ROOT/pve-1 ro root=ZFS=rpool/ROOT/pve-1 boot=zfs quiet acpi_enforce_resources=lax

reboot

test again:

# modprobe it87
modprobe: ERROR: could not insert 'it87': Device or resource busy

hmmm, crazy.
