Once I feel comfortable with the process management related topics I will move to the process scheduling and memory management. Thank you very much for pointing me to the procfs direction as an easy and fast way to test and experiment with the kernel Rajat. =) > > On Wed, Oct 27, 2010 at 6:19 AM, Gavin Guo <tuffkidtt@xxxxxxxxx> wrote: >> >> 2010/10/27 Gustavo Silva <silvagustavosilva@xxxxxxxxx>: >> > Hello my friends, >> > >> > At this moment I'm reading the Process management chapter of Linux >> > Kernel Development Third edition so I'm thinking about some exercises >> > in order to get the most out of the lecture. >> > I'm thinking about to implement a System call that receives a Process >> > ID as input and gives as output all the parents of the process.

I have been playing with character drivers as well and I think thats a good next-step in the process of getting familiar with the kernel. Thank you very much for the recomendation. =) Best regards to everybody, Gustavo Silva -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
