HI Harsh >>>In the Kernel Janitors there is a TODO guide to debug the kernel ther you >>>could find hot to run a random config in order to break the compilation of >>>the kernel http://code.google.com/p/kernel-janitors/wiki/TODO >>>To understand linux code check this http://www.linuxfromscratch.org/ >>>and learn the more that you can about C you will need it, a really good book >>>is C Programming Language (2nd Edition) from Kernigan and Ritchie I think that a good way to start to undestand the Kernel code is to make your own Kernel modules check this The Linux Kernel Module Programming Guide http://www.tldp.org/LDP/lkmpg/2.6/html/index.html and try to make your own Kernel Module try to make a char driver and to make a procfs program than and your procfs module to your OS and used it latter this is a really good web page in order to see how to use you char driver to turn on a led in your parallel port for example ( this is a really good device driver example ) : ) http://www.freesoftwaremagazine.com/articles/drivers_linux?page=0%2C0 I hope it helps you It helps me Sincerely yours Victor Rodriguez -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
