Wel, that's only actually helpful for the kernel if somebody's already
done the port to that board (which it seems they have, since it already
has a kernel package), and failed to add an I2C driver already.

The other thing that you could do that would benefit the kernel is to take
the vendor's code (which is probably some ancient creeping horror like 3.4
or even a 2.6.something), and get the drivers up to 4.6 level and get them
upstreamed.

Greg KH is almost certainly reading this, and he *loves* helping get
drivers into the main kernel :)

Greg, meet Aric.  Aric, meet Greg.  :)

Yeah, that sounds good. Who know Greg's e-mail,or where to find him?

Hi Valdis,
      Do you mean the Grag is "Greg KH"<greg@kroah.com>; ?  But I'm still learning, where can I get a simple task to get into? The test task is also okay, pls give me test specification or what test env. it required.

There is no Grag, we only have Greg KH.
Now that you are learning maybe you can start with
http://eudyptula-challenge.org/

and:
1) never toppost
2) never send mime mails.

A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?

Now do you understand?

How to fast master kernel

[Aric]

Hi all,
     I buy many boards, already on my hands boards: S3C6410, AR9331,AllWinner A20, H3. 
  
 But for each board, it have dedicated kernel code package. For example, what I want to do first, it I can write kernel drivers and kernel code freely. I can easily add a I2C (AT24C02) device and finished its driver in a short time.   Any good tutorial or good practise to guide me, make me easily to do that? If we have more small code example it will help? 
  Sorry all for my stupid questions.

  all those F-1 race cars run linux, anyway, so ... no big deal.

Yeah, that was me...

I'm also the one who said that we're approaching the point where the number
of people who are actually qualified to do serious hacking on the kernel
innards (like the scheduler, vfs, etc, not just a driver) is on the
same order of magnitude as the number of people qualified to be Formula-1
race car mechanics....

  not sure who it was (maybe even valdis) who once said, "Saying you
want to get into kernel programming but have no idea where to start so
can someone give you suggestions is like saying you want to write a
book but don't know what to write about so can someone give you any
ideas."

Step 0: Figure out *why* you want to contribute.  The answer you seek
depends a lot on why you're asking the question....

Just because it sounds cool?

You bought something on Ebay and discovered it doesn't have a driver?

Your employer just told you that your company's new widget needs a driver?

You have a particular interest in filesystems, or crypto, or hypervisors, or
whatever?

You just want to give back to the community?

(If the latter, I suggest just building a new linux-next kernel every
week or so, and report any issues.  We need more testers more than we need
more code, and the learning curve for testing is a *lot* lower...)

In fact, here's the learning curve:

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

$ git remote add linux-next git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
$ git fetch linux-next
$ git fetch --tags linux-next

(build and boot a test kernel)

... # later on a week or so later...

$ git remote update     (note that 'git pull' does *not* work for linux-next)
(mount and boot a test kernel)

Yeah, it really *is* that simple.. :)

Aric,

You might want to start by reading all the documentation and
correlated how to's on the following website:
http://kernelnewbies.org/. This would probably be a good start.

Happy kernel hacking.
