Bonjour,
Je cherche une méthode pour identifier un plantage du kernel suite à l'exécution de mon module Xenomai.
En résumé, mon module [xeno_s3c2440_adc] plante tout au bout de quelques (longue) minutes.
Et je n'arrive pas à identifier l'origine du problème.

Merci pour l'information.
Je viens de faire le test.
CONFIG_XENO_OPT_SYS_STACKPOOLSZ=512
CONFIG_XENO_OPT_SYS_HEAPSZ=512
Mais j'ai toujours les mêmes problèmes.
Je regarde actuellement mon code, je pense qu'il s'agit de spin_lock.
Je ne suis pas sur que cela fonctionne correctement avec Xenomai.
Je vais le transformer en mutex [rt_mutex_acquire]

Bonjour,
J'ai remplacé la fonction ioremap par ioremap_nocache.
J'ai eu un beau succès hier (plusieurs heures de fonctionnement sans plantage)
Depuis, retour à la case de départ. (plantage au bout de quelques minutes)
Pour ceux que cela intéresse, il y a un moyen de retrouver la localisation du plantage en utilisant le programme arm-linux-addr2line.
(compilé dans la chaîne buildroot)
Il faut récupérer la localisation de la fonction qui a planté (récupérer le registre "pc" afficher ans le message oops)
exemple de commande :
output/host/usr/bin/arm-linux-addr2line -f -e ./output/build/linux-3.2.21/vmlinux c027fb38

Bonjour,
xeno_s3c2440_adc est un module que j'ai crée.
Tu retrouve les sources un peu plus haut.
(Par contre, il comporte un bug, en suivant le conseil que j'ai mis après, cela devrait fonctionner sans problème - du moins je n'ai pas constaté d'erreur)
