Re: Getting Started
(This mail is in response to Getting Started on 6/11/2014)
Alan and Greg, thank you both for your responses. At this point (after
dealing with real life of course), I've read through the driver-writing
guide and driver(9), config(9), and autoconf(9), and have modified the
kernel files so that my template driver is compiled in successfully
(http://pastebin.com/AF7iSmfu). sys/dev/isa/files.isa, my custom kernel
config, and sys/arch/i386/conf/majors.i386 have also been modified
accordingly (I used char 94 block 25 for my own source tree). As of right
now, I'm much better with CVS, and build.sh, and have a shell script to swap
out a working kernel with my own (I use a remote machine for compiling).
Greg: RAM will have to wait for now (parity SIMMs still cost an arm and
leg), but I'll humor myself and try the tests anyway.
Next is to actually get a driver working for this old CD-ROM device that is
almost before my time :). Greg brings up a valid point when, in response to
my delusions of writing a driver, he mentions “The question is who will
spend time to address them and integrate it, and the easier you make that
the better”. I'm writing a driver for a rather old piece of hardware for fun
and education, not for use by the general public. Most people will not need
this driver, and so I expect myself to be left to my own devices when
writing the driver. In fact, it would be great if I could get this driver
working without any questions at all- and I think that might be possible.
Although the driver might be for an old device, I'm under the impression a
working driver- written up to standards- would be accepted anyway as a
meaningful contribution- educational at least. And who knows- it might be of
use to others. With that being said, where would be the proper place to get
feedback (WITHOUT harassing the developers) as I develop this driver to ease
integration? I do want to make this easy for all parties involved (besides
myself and my sanity :P), and I'm grateful for any help I can get if
necessary. I figure the tech-kern mailing list (pre-bare minimum
implementation) or problem reports (when I have a bare-minimum
implementation, like pcdopen and pcdread) are most appropriate, but does
anyone more experience than me at writing device drivers have any advice?
Thanks for any help anyone can give me! Also, Alan wrote: "It's easier to
deal with one question at a time, unless the questions are closely related."
My mistake :P.
