Kernelin päivitys

Martin Michlmayr on tehnyt uuden kernelin D-Link DNS-323 laitteelle, joka tukee ohjelmistopohjaista tuulettimen säätöä sekä laitteen hardware sensoreita.

Asennus menee näin:
Lisätään Martinin repository  /etc/apt/sources.list -tiedostoon
# echo "deb http://people.debian.org/~tbm/orion lenny main" >> /etc/apt/sources.list

Noudetaan Martinin gpg-avain:
# gpg --keyserver wwwkeys.eu.pgp.net --recv-keys 29BE5D2268FD549F
# apt-key add /root/.gnupg/pubring.gpg

Ja päivitetään tietokanta:
# apt-get update

Kernelin asennus:
# apt-get install linux-image-orion5x
# reboot

Kun purnukka käynnistyy uudelleen, voi uden kernelin testata
# uname -a
Linux purnukka 2.6.32-2-orion5x #1 Fri Feb 12 18:12:26 UTC 2010 armv5tel GNU/Linux

Asennetaan lm-sensors:
# aptitude install lm-sensors -y

# sensors-detect

... << poistettu tauhkaa >>

We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no):yes

...

Do you want to scan the ISA I/O ports? (YES/no): no
...

Do you want to scan for Super I/O sensors? (YES/no): no

...

Some south bridges, CPUs or memory controllers may also contain
embedded sensors. Do you want to scan for them? (YES/no): 
Silicon Integrated Systems SIS5595...                       No
VIA VT82C686 Integrated Sensors...                          No
VIA VT8231 Integrated Sensors...                            No
AMD K8 thermal sensors...                                   No
AMD K10 thermal sensors...                                  No
Intel Core family thermal sensor...                         No
Intel AMB FB-DIMM thermal sensor...                         No

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `lm75' (should be inserted):
  Detects correctly:
  * Bus `mv64xxx_i2c adapter'
    Busdriver `UNKNOWN', I2C address 0x48
    Chip `lm75' (confidence: 6)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue: 

To load everything that is needed, add this to /etc/modules:

#----cut here----
# I2C adapter drivers
# modprobe unknown adapter mv64xxx_i2c adapter
# Chip drivers
lm75
#----cut here----

Do you want to add these lines automatically? (yes/NO)yes
# jed /etc/modules 
# modprobe lm75

# sensors

Adapter: mv64xxx_i2c adapter
temp1:       +48.5°C  (high = +80.0°C, hyst = +75.0°C)
