There are two main areas of learning you can consider: the kernel's core functionality like its virtual memory subsystem, and its device drivers. For the former, a good resource is Mel Gorman's work: http://is.gd/34W69 ... which is probably still available online as well. For device drivers, there's the well known _Linux Device Drivers_, which is available in print and as PDFs. But whatever you read, make sure to refer to the kernel sources themselves as you read. It will help you to relate what you learn to something concrete. You can use your reading as a chance to get to know the layout of the kernel sources. It also helps to have a specific project in mind. Without some goal in mind, I find it more difficult to retain new information. Finally, here's a script that you might like to use in searching for specific functions and macros in the kernel. Often the best way to understand something is to look at how it is being used in the kernel. There are alternatives like cscope. #! /bin/sh # kern-find-grep - find regex in kernel sources # test -z "$*" && exit 0 nocase= if test "$1" = "-i"; then nocase="-i" shift fi extended= if test "$1" = "-e"; then extended="e" shift fi # set -x find . -type d -name .svn -prune -o \ -type d -name .git -prune -o \ -type f \ ! -name '*.o' \ ! -name 'vmlinu*' \ ! -name '.tmp_*' \ ! -name '*.ko' \ ! -name '*.ver' \ ! -name '.*.o.cmd' \ ! -name '.*.ko.cmd' \ ! -name '*~' \ ! -name '*.a' \ ! -name '*.so' \ -print0 | xargs -0 -e ${extended}grep --color=never $nocase -n -e "$*" -- Ed Cashin <ecashin@xxxxxxxxxx> http://noserose.net/e/ http://www.coraid.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
