Hi,

I'd like to ask how can I use the scull driver today?
The scull driver appears in the book "Linux Device Drivers, Third
Edition".

I am using linux vesion 5.1.6

I found the code of scull here:
https://github.com/starpos/scull

But, it says there that the code is compatible with linux version 2.6.35.

I've tried to port the code to run with my linux version, but I got
stuck when it comes to exchange the old semaphores with the newly
introduced mutexes.

I also tried to install linux version 2.6.35 on my machine, but I could
compile the code. I assume it's related to the gcc version, but I don't
know how to handle this.

Can you give me some advice here?

Thanks,
Yacov

Hi Yacov,

you can use the following repository which contains updated code for recent
kernels. I tested it last year and IIRC it was working fine.

https://github.com/martinezjavier/ldd3

It is now possibly a bit out of date for the 5.1 kernel, but whatever you
encounter will probably be easier to fix than the original code of the book.

Best,
Elias
