===== ath10k sources location =====

//ath10k// development happens in Kalle Valo's ath.git tree on kernel.org: 

https://git.kernel.org/cgit/linux/kernel/git/kvalo/ath.git/

To clone the tree: 

<code>git clone git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git</code>

ath10k driver is located in directory drivers/net/wireless/ath/ath10k. 

If you just want to browse the source code with your web browser this links always points to latest version of ath10k: 

https://git.kernel.org/cgit/linux/kernel/git/kvalo/ath.git/tree/drivers/net/wireless/ath/ath10k

Periodically Kalle Valo pulls the ath tree into wireless-drivers-next tree. Then David Miller pulls it to net-next which is eventually pulled by Linus Torvalds to official kernel releases. As a rough estimate it takes 2-4 months for a patch to propage from ath.git to an official Linux release.


===== Submitting patches =====

Send patches to the mailing lists below. Kalle Valo reviews the patches within the next few days and, if they are ok, commits them to ath.git. 
      * To: [[mailto:ath10k@lists.infradead.org|ath10k@lists.infradead.org]] 
      * Cc: [[mailto:linux-wireless@vger.kernel.org|linux-wireless@vger.kernel.org]] 

Preferably use ath.git master branch as the baseline for patches. Other trees can be used as well, but then the chances of conflicts are higher. 

More info about submitting patches: 
        * [[en/developers/Documentation/SubmittingPatches|en/developers/Documentation/SubmittingPatches]] 
        * [[en/developers/Documentation/git-guide|en/developers/Documentation/git-guide]] 

Guidelines for patches: 
          * MUST follow [[https://www.kernel.org/doc/Documentation/SubmittingPatches|Documentation/SubmittingPatches]]
          * MUST be compiler warning free. 
          * MUST be sparse warning free. 
          * Commit log MUST not be empty. 
          * The commit log MUST answer the question "Why?": 
             * Describe the motivation behind the bug. 
             * How does it change the functionality from user's point of view? 
             * Does it fix a bug? If it does, please describe the bug (doesn't need to be long). Also if there's a public bug report add a link to the bug report. 
             * If a problem has been found during code review and doesn't fix a known issues, mention that in the commit log.
             * Ingo Molnar has written [[https://lkml.kernel.org/g/20150314075357.GA8319@gmail.com|a nice description]] about what maintainers are looking from a commit log. 
          *   If others have reported the issue commit log SHOULD use Reported-by: and Tested-by: tags. 
          *   SHOULD be checkpatch clean: 
               * FIXME: add checkpatch example with correct arguments 
          *     Patches SHOULD be sent with git send-email tool. 
          *     Patchsets SHOULD contain no more than 12 patches. 
          *     Patches SHOULD follow [[en/users/Drivers/ath10k/CodingStyle|ath10k coding style]] 

The terminology is from [[http://www.ietf.org/rfc/rfc2119.txt|http://www.ietf.org/rfc/rfc2119.txt]] 

The ath10k patch flow is this: 
          * Patch gets posted to the mailing lists. 
          * Kalle immediately applies the patch to pending branch for build testing. 
          * Kalle waits two business days for patch being under review (unless the patch is urgent). 
          * If no comments or warnings, Kalle applies the patch to ath-next branch and sends a "Thanks, applied" reply. 
          * Kalle merges ath-next to master branch immeadiately after the patch is applies. 
          * Kalle merges ath-next into wireless-drivers-next roughly every 2-3 weeks 
          * David Miller merges wireless-drivers-next into net-next every two weeks or so 
          * Linus Torvalds merges net-next into linux.git during [[https://www.kernel.org/doc/Documentation/development-process/2.Process|merge window]] 


===== Git branches =====

ath.git contains multiple branches: 

  * master  : The default branch selected when cloning the tree. Everyone working on ath10k (or ath6kl) should use this branch. Follows John Linville's wireless-testing tree and contains the latest -rc release from Linus Torvalds + latest wireless code from John + latest ath10k/ath6kl code from ath-next branch. Usually the branch is rebased after a merge window (after -rc1 is released). Due to unclean history bisect might not work, better to use ath-next for bisecting. 
  * ath-next  : Based on John's wireless-next tree and John will pull from this branch. ath6kl/ath10k patches are commited to this branch first and then merged to the master branch. For bisect runs it's better to use this branch instead of the master branch. 
  * pending  : Used for building and runtime testing patches under review. Is rebased almost daily and hence commit ids are NOT stable. Use this only if you know what you are doing.
