Recompilation du noyau Linux 2.6 pour amd64 dual core
Ces pages n'ont pour objectif que de faire partager mes notes d'installation. Il y a donc
très peu d'explications, surement des erreurs/oublis et il est probable que le cheminement
employé ne soit pas le plus court, mais bon ça marche bien !
Le noyau générique fourni par Debian n'est pas dual
core, donc on recompile le noyau avec l'option smp et les bons pilotes. On en profite pour
découvrir le matériel plus en profondeur :
#lsmod
pour connaître les modules utilisés
actuellement à garder dans le nouveau noyau
#hwinfo
pour connaître le matériel
installé
On découvre que c'est une carte mère Gigabyte
"Gigabyte Technology Co., Ltd."
"K8NF9-NF"
"NEC"
"Socket 939"
"AMD Athlon(tm) 64 X2 Dual Core Processor 4200+"
Ensuite il faut relever les noms des processeurs ou des pilotes
détectés dans les sections : kernel log

#sensors-detect détection des processeurs
compatibles I2C/SMBUS sur la carte mère
...
Probing for PCI bus adapters...
Use driver `i2c-nforce2' for device 00:01.1: nVidia Corporation nForce4 SMBus (MCP)
Probe succesfully concluded.
...
Driver `eeprom' (should be inserted):
Detects correctly:
* Bus `SMBus nForce2 adapter at 1c00'
Busdriver `i2c-nforce2', I2C address 0x50
Chip `SPD EEPROM' (confidence: 8)
* Bus `SMBus nForce2 adapter at 1c00'
Busdriver `i2c-nforce2', I2C address 0x51
Chip `SPD EEPROM' (confidence: 8)
* Bus `SMBus nForce2 adapter at 1c00'
Busdriver `i2c-nforce2', I2C address 0x52
Chip `SPD EEPROM' (confidence: 8)
* Bus `SMBus nForce2 adapter at 1c00'
Busdriver `i2c-nforce2', I2C address 0x53
Chip `SPD EEPROM' (confidence: 8)
Driver `it87' (should be inserted):
Detects correctly:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `ITE 8712F Super IO Sensors' (confidence: 9)
I will now generate the commands needed to load the I2C modules.
Sometimes, a chip is available both through the ISA bus and an I2C bus.
ISA bus access is faster, but you need to load an additional driver module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)?
To make the sensors modules behave correctly, add these lines to
/etc/modules:
