Firewire ieee1394 in Scientific Linux 5

Download e Setup

Installare repo atrpms (e settarlo dormiente, per usarlo solo quando si vuole e non ad ogni yum update)

rpm --import http://atrpms.net/RPM-GPG-KEY.atrpms

Creare

/etc/yum.repos.d/atrpms.repo

e incollarci questo

[atrpms]
name=Fedora Core $releasever - $basearch - ATrpms
baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
gpgcheck=1
enabled=0

Installare i moduli del kernel:

yum --enablerepo atrpms install ieee1394-kmdl-`uname -r`.`uname -m`

se dovessero fallire le dipendenze con il kernel, cercare un kernel con versione adatta (identica) alla versione del modulo di atrpms

Ora, Controlliamo se si sono installati i moduli per il kernel attivo:

rpm -q ieee1394-kmdl|grep "`uname -r`"

Se il comando da risultati in output, saltare il punto successivo.

Controlli Installazione

Kernel attivo

uname -r

Archittettura

uname -m

moduli ieee1394 installati

find /lib/modules/ -iname *1394*

kernel disponibili (da GRUB)

grep kernel /boot/grub/grub.conf |grep -v ^#
  • Controllare quale kernel si avvia default
grep default /boot/grub/grub.conf 

Primo della lista

default=0

Avvio

  • Se abbiamo verificato che i moduli installati hanno un kernel con versione IDENTICA (es. 2.6.18-8.1.14)
  • Se abbiamo verificato che i moduli installati hanno un kernel con architettura IDENTICA (es. i686)
  • Se abbiamo verificato che questo kernel con versione e architettura IDENTICA si avvia di default

Si può proseguire

A Caldo

Caricare i moduli direttamente, senza riavviare.

modprobe ieee1394
modprobe raw1394
modprobe ohci1394
modprobe dv1394
modprobe video1394

A Freddo

reboot

Controlli Firewire

Controlliamo la partenza e poi i messaggi del kernel:

dmesg|grep -i 1394

Dovrebbe esservi almeno una riga così:

ieee1394: raw1394: /dev/raw1394 device initialized
