looking for current, online kernel-related tutorials

[Robert P. J. Day]

  a *very* wide-ranging post, but i'm currently trying to collect any
well-written and *current* tutorials on *any* aspect of kernel
programming, device drivers and related stuff like that there --
especially those that come with working, hands-on examples.

  the biggest drawback with a lot of the online tutorials and the
in-kernel Documentation content is that much of it is simply
out-of-date and finding really good tutorials is a bit of a challenge,
so if anyone has suggestions for things like that (or has written such
things), by all means, post pointers to them and i'll start making a
list.  and what's in it for you?

  i'm starting some wiki pages for as many topics as i can think of:

http://www.crashcourse.ca/wiki/index.php/Kernel_topics

for now, things will be fairly concise, i just want to collect the
content.  these wiki pages will be permanently publicly available, so
it's not like i'm asking anyone to do the work, at which point i'll
take the results and keep them for myself.

  in addition, the *eventual* goal is to incorporate the results in
some updated linux kernel programming courseware, which will all be
released under the creative commons license so, again, at no point
will any of this content suddenly disappear.

  at the moment, i'm working with karim yaghmour of opersys.com, who
recently open-sourced all his courseware --
http://www.opersys.com/training -- and i'm working on updating the two
linux courses for the 3.x kernel.  when those linux course manuals are
updated, they will be posted and will still be under the creative
commons license.

  in the end, i may reorganize the wiki content if i come up with a
more accessible structure, but it will never disappear.  so if you
know of any excellent tutorials out there, let me know, and i'll add
that to the wiki where everyone can take advantage.

  and now, back to work ...

In case you don't know these:

* free-electrons
* elinux.org

These are superb sources of information.

Any plans to include this content in kernelnewbies.org?  It seems like
tutorials on kernel programming should be linked from there.

I wrote an tutorial for Linux magazine on how to get the Portland State
Aerospace Society's USB sensor nodes working.  I doesn't involve any
kernel drivers, but it does involve using the userspace libusb interface
to talk to the USB device.  Unfortunately, it is old, and I'm not even
sure the git repo links still work.

I poke around and see if I find anything more recent.

  that's a nice idea, but i have a selfish reason to host all of this
at my (soon-to-be-revamped) website -- training is how i make a
living, and having numerous tutorials on various aspects of kernel
programming and device drivers and so on brings in readers and
represents marketing for me.  from a business perspective, it's
nothing more than attracting eyeballs that might then hire me to teach
a course.

  that said, all of this is going to be publicly available (creative
commons license) so there won't be any restriction on who can read it.
certainly, anyone is welcome to link to what eventually gets
published at my site.

  over the next few weeks, much will be updated and re-organized, and
i'll post pointers to whatever goes up.

Robert,

I like this:
http://www.freesoftwaremagazine.com/articles/drivers_linux

It is not current but not very old.

  not bad ... definitely dated as it uses a parallel port as an
example, and deprecated register_chrdev() for device registration.
but not bad.

  what i'm after these days is more up-to-date and much more *focused*
tutorials if people run across them.  as in, rather than another
example of how to write a character driver, i'm collecting writeups
like this:

http://www.ibm.com/developerworks/linux/library/l-tasklets/index.html

that is, a solid coverage of a single topic in some detail,
particularly if it can tie back into code taken from the kernel.

  anyway, off to write more tutorials.

  at the risk of putting a few noses out of joint, a main reason why
i'm not keen on adding more content to kernelnewbies is that what's
there is, in many cases, spectacularly out of date, and newer content
would just get lost in the shuffle.

  consider the links here:

http://kernelnewbies.org/Documents

follow some of those links and see where you end up.  i mean,
seriously, "working with the kernel source in CVS"??  and a number of
other links there have very little remaining value.

  rather than trying to add more content, a higher priority would be
to *cleanse* that documentation page of what obviously has little
value, and start over.  thoughts?

That's what I'm planning on doing to the wiki.  You're right that it's
out of date and very disorganized.  So I'll take a crack at it and see
if there's a better structure.

  i'm going to take a different approach to reorganizing all of the
tutorials at my site.  first, i'm going to get all the useful stuff
*out* of the wiki -- for this sort of thing, wikis are a waste of
time.  good for quick and dirty, utterly useless for anything else.

  instead, i'm going to move it all under drupal as books or stories
or whatever is appropriate, where only i will have the authority to
change the content, but people will be allowed to *comment* on
individual articles.  that way, i can post stuff and be notified down
the road by people leaving comments that something's changed and needs
updating (effectively crowdsourcing all of that work).

  at this point, i don't see any other way to do this that's as
effective.
