Subject: Char device initialization
Date: Wed, 09 Nov 2011 11:41:58 -0200	[thread overview]
Message-ID: <4EBA8326.8020809@gmail.com> (raw)

I'm trying to create a example char device. The example compiles fine, 
but when I try to "cat" I got "No such device or address". I have
reviewed the code thousend times and can't see what I'm missing

Here is the code -> http://pastebin.com/Td03U0fK

The read method is not good, I know, but is never called.

I use my own running kenrel to test, I know that is danger. I'm building 
a qemu enviroment to test this better.

Here is uname -a:
Linux archlinux 3.0-ARCH #1 SMP PREEMPT Fri Oct 7 11:35:34 CEST 2011 
x86_64 Intel(R) Core(TM) i3 CPU M 370 @ 2.40GHz GenuineIntel GNU/Linux

Any idea?

Thanks
