You don't happen to be the student of the professor of rpi.edu (if I am not mistaken) whom I just mailed back are you? =) If you want to document the writing of the drivers, you might want to stick around me, since I have been dogging in this subject for the past few months. >It would be a big help for me if you could answer the following questions: > >1)Are BSD drivers not really documented?(I fear that I may not end up >re-inventing the wheel) Depends on which version of FreeBSD. Prior to CURRENT (4.0) we used the standard BSD/Unix way of writing device drivers. That means we used bdevsw[] and cdevsw[]. We recently collapsed both the character devices and block devices into one cdevsw. >2)I am new in this field. Will it be possible for you to tell me from where >should I start as I dont have any experience in this field? Please see the email from Greg Lehey and myself in response to another inquiry about writing device drivers, since it is too long to repeat here.
