If want to write a loadable module which "implements" a char device ("virtual", no real device present). How do I get the correct "/dev/foo" to appear automaticly? What is the current recommended solution (kernel 2.6.17 in Ubuntu and later).
static int major; static int __init foo_init(void) { ... major = register_chrdev(0, "foo", &fops); .... } static void __exit foo_exit(void) { ... if (major > 0) unregister_chrdev(major, "foo"); ... } I thought that the above code would be enough to trigger the "udevd", but apparently not (if it should, what is the match rule I have to use? DRIVER=="foo" or KERNEL="foo[0-9]*"? None of these seem to work). Do I have to do some additional poking with sysfs? I can see my module there, but nothing else. The problem seems to be that most information I find from books or net is out of date for 2.6, or carries note "these things are currently been changed". A pointer to a definitive documentation would also do! - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
