Hi all , One curious pattern I have come across Linux community is interest in writing device drivers. As far as I know , this boils down to learning a) How to write a kernel module ? b) Kernel memory allocation functions c) ioctl/proc file interface d) open/read/write /close paradigm Alessandro Rubin's book gives a good overview of the stuff mentioned above. Once that is over , I think , we need to go vertical with a) USB (filter drivers ) b) File Systems c) Networks d) Driving custom hardware based devices which follows well known interface. I think , writing device drivers now a days is just a matter of learning some operating systems data structures and there are not much career opportunities in the area. Because , in modern operating systems , most of the drivers are written by OS vendor ( among Linux community , there are some heavy weights who fill the role of OS vendor ) or some OEMs. Ideally , speaking the time and energy can be spent on writing Application software using C/C++ as the primary programming language. There is shortage of people in the area and there is even more shortage for people who can write multi-platform application code. These are my thoughts. Any comments ? regards Praseed Pai
