温度管理(lm-sensors)(sagittarius)

続いて、sagittarius で lm-sensors と xsensors を導入する。

やり方は全く一緒だ。
$ sudo apt-get --simulate install lm-sensors
$ sudo apt-get install lm-sensors

lm-sensors の設定を作成
$ sudo sensors-detect
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# Board: ASUSTeK COMPUTER INC. Z170 PRO GAMING
# Kernel: 4.4.0-104-generic x86_64
# Processor: Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz (6/94/3)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): (そのままエンター)
Module cpuid loaded successfully.
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No

AMD Family 11h thermal sensors... No
AMD Family 12h and 14h thermal sensors... No
AMD Family 15h thermal sensors... No

(driver `coretemp')
Intel AMB FB-DIMM thermal sensor... No
Intel 5500/5520/X58 thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): (そのままエンター)
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): (そのままエンター)
Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): (そのままエンター)
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): (そのままエンター)
Found unknown SMBus adapter 8086:a123 at 0000:00:1f.4.
Sorry, no supported PCI bus adapters found.

Next adapter: i915 gmbus dpc (i2c-0)
Do you want to scan it? (yes/NO/selectively): (そのままエンター)

Next adapter: i915 gmbus dpb (i2c-1)
Do you want to scan it? (yes/NO/selectively): (そのままエンター)

Next adapter: i915 gmbus dpd (i2c-2)
Do you want to scan it? (yes/NO/selectively): (そのままエンター)

Next adapter: DPDDC-D (i2c-3)
Do you want to scan it? (yes/NO/selectively): (そのままエンター)

Next adapter: DPDDC-E (i2c-4)
Do you want to scan it? (yes/NO/selectively): (そのままエンター)


Now follows a summary of the probes I have just done.
Just press ENTER to continue: (そのままエンター)

Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO) (そのままエンター)

Unloading cpuid... OK

ありゃ…、coretemp 以外の対応ドライバーが見つからなかったっぽいな。
これでドコまで見られるのだろうか…。

実行してみよう。
$ sensors

temp2: +29.8°C (crit = +119.0°C)

asus-isa-0000

う～ん。ちょっと温度表記数が少ないかな…。

ちょっと気になったので、先程の sensors-detect で「Do you want to scan it?」の質問のところを、全て yes で答えたが、結果は変わらずだった。
CPUの温度項目しか見られないのね。

続いて、 xsensors を導入。
$ sudo apt-get install xsensors

動かしてみる。
$ xsensors &

表示はされたけど、項目数は少ない。
まぁ、CPUの温度が分かるだけでもいいか…。
