2011/11/05(Sat)P4B266-Eでlm_sensorsを動かす

2011/11/05 3:26 Software::Linux
一昔前に買ったPentium 4 (Socket 478)なCPUが刺さるASUSTek P4B266-EにFedoraをインストールしてみたのだが、温度センサー系がうまく動作しない……。
まあ、lm_sensorsのsensors-detectで"no sensor detected."等と言われるのは良くある事なのだが、今回はちょっと様子がおかしい…？
完全動作ではないけど、トリッキーなことをしたのでメモ。

前提条件

マザーボードは冒頭に書いたとおり、ASUSTek P4B266-E.
ついでにCPUはPentium 4 Northwood 1.8AGHz.
OSはFedora 15のx86.
ちなみにカーネルはyum updateで入るものの最新で、sensorsのバージョンはこれ。
$ uname -r

2.6.40.6-0.fc15.i686.PAE

$ sensors -v

sensors version 3.3.1 with libsensors version 3.3.1

hddtemp

これは特に問題なし。
$ sudo yum install hddtemp
して、
$ hddtemp /dev/sda

/dev/sda: ST3160815AS: 42°C
てな具合にすぐ表示される。ちょっと熱いかな…？

lm_sensors

導入は楽。yum一発。
$ sudo yum install lm_sensors

まずはsensors-detect

今回のクセモノ。
まずは普通にsensors-detectをやってみる。
# sensors-detect

# sensors-detect revision 5984 (2011-07-10 21:22:53 +0200)
# Board: ASUSTeK Computer INC. P4B266-E

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):

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):

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):
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): 
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):
Sorry, no supported PCI bus adapters found.

とまあ、検出はうまくできているように見える。
しかし、systemctlを使ってlm_sensors.serviceを起動するところで失敗。こんなパターン初めてなんだけど…。

ちなみにsensorsを実行しても
#  sensors

No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
となるだけ。

lm-sensors.orgを見る

とりあえず、lm-sensors.orgのDevice Support Statusを見てみる。
ふーむ、w83781dは……
No datasheet, incomplete support.
なぬ、これは動かない…？
と思って色々サイトを回っていたら、ASUS Pen4 motherboardsなどが引っかかった。
どうやら、P4Bシリーズは訳ありでSMBusが普通には見えないらしく、ちょろっと小細工しないといけない模様……。

文献に書いてあったように、pcitweakというコマンドを探したりしたが、見つからず挫折気味…。
と思ったら、prog/hotplug/README.p4bというものを参考にするといいよ！というBBSの回答をいくつか見かけたので、lm-sensorsのソースコードをダウンロードしてチェック。(/prog/hotplug/*)
すると、README.p4bと同じ階層にunhide_ICH_SMBusというスクリプトがあったので、中身をぱらぱらっと見てみると、おおよそ先の文献と同じような事をやっているようだったので実行してみた。
# ./unhide_ICH_SMBus

おー、出た出た！
って、inやtemp3,4はなんかおかしい気がするが、temp1,2は割とまともなようなので信じてみることに。
ちなみに自分の構成では、電源ユニットのFanにはSpeedを計測するためのピンがないので値が出ないのは正常だし、その他Chassis Fan等も全部2pin接続なので同様。
# CPU Fan位は出てくれてもいいんだけどね…

先のDevice Support Statusにも、データシートがないから不完全なサポートだよ、と明記があったくらいなので、この程度で勘弁してみる。

ちなみに、unhide_ICH_SMBusスクリプトの最後に、
Remember: system suspend/resume is no longer safe to use.
とあったが、基本的にサーバ利用なのでsuspend/resumeすることは無いので心配いらないな。
電源状態を変更するところでSMBusが見えてると問題が起こるから隠されてたりするのかなぁ…。


うーむ、やっぱりlm_sensorsはムズい…。
# VPSとかなら、こんなの気にしなくていいんだろうけど、VPSは味気ないしね……
