Народ, кто писал драйвер для символьного устройства под Linux с ядром 2.6 помогите разобраться. 1. Откуда взять функцию scull_follow используемую методами read и write? Или что она хотябы из себя представляет и что в ней должно происходить? 2. У кого сохранились какие либо наработки? Поделитесь пожайлуста. Заранее благодарен!!!

После компиляции модуля образовался файл mydrv.ko Но при его инсталяции появляется ошибка: [root@localhost Nikolai]# insmod ./mydrv.ko insmod: error inserting './mydrv.ko': -1 Invalid module format Что это значит?

Скачал исходник ядра kernel-2.6.9-1.667asp.src.rpm. Запускаю его... в результате мне выдает кучу сообщений 1:kernel предупреждение: пользователь build не существует - используется root предупреждение: группа build не существует - используется root предупреждение: пользователь build не существует - используется root Что делать? За ранее благодарен!

Я первый раз с этим сталкиваюсь. Просто возникла необходимость написания драйвера для диплома. Когда я пробую собрать модулю по примерам то че то у меня не получается! Пожайлуста направте на путь истинный. ___________________________ Файл mydrv.c #include <linux/module.h> #include <linux/init.h> MODULE_LICENSE("GPL"); static int __init my_init(void) { printk("<1>Da\n"); return 0; }; static void __exit my_cleanup(void) { printk("<1>Net\n"); return; }; module_init(my_init); module_exit(my_cleanup); Файл makefile obj-m += mydrv.c Команда для компиляции: make -C /lib/modules/`uname -r` SUBDIRS=$PWD makefile После чего не выдается ни каких ошибок и сообщений вообще. И получается какбудто команда выполнена. Хотя объектного файла mydrv.o я не нахожу ни где. makefile и mydrv.c расположены в одной папке /home/Nikolai. Компилирую тоже из этой папки.
