I did a operating system laboratory class at BarcelonaTech.<br>
It consists in adding basic functionality to an existing OS (it was<br>
based on Linux 2.4). This included adding system call table, process<br>
scheduling and semaphore support (as far as I remember).<br>
<br>
As a second part we had to implement a kernel module which these days<br>
was able to count several system calls before executing them.<br>
I have the source code, you can find it on my blog (see below) but I'm<br>
not sure if I have the instructions for the assignments...<br>
<br>
Cheers,<br>
