This will make things +easier on the maintainers. Not all of these guidelines matter for every +trivial patch so apply some common sense. + +1. Always _test_ your changes, however small, on at least 1 or + 2 people, preferably many more. + +2. Try to release a few ALPHA test versions to gerrit. Announce + them onto the coreboot mailing list and IRC channel and await + results. This is especially important on coreboot core changes, + but also for device drivers, because often that's the only way + you will find things like the fact revision 3 chipset needs + a magic fix you didn't know about, or some clown changed the + chips on a board and not its name. (Don't laugh!) + +3. Make sure your changes compile correctly in multiple + configurations. In particular check that changes work for all + boards in the tree (use abuild!) + +4. When you are happy with a change make it generally available for + testing in gerrit and await feedback. + +5. Make your patch available through coreboot's gerrit code review + system, and add the relevant maintainer from this list as a code + reviewer. Be prepared to get your changes sent back with seemingly + silly requests about formatting and variable names. These aren't + as silly as they seem. One job the maintainers do is to keep + things looking the same. Sometimes this means that the clever + hack in your mainboard or chipset to get around a problem actually + needs to become a generalized coreboot feature ready for next time. + + PLEASE check your patch with the automated style checker + (util/lint/checkpatch.pl) to catch trival style violations. + See Documentation/CodingStyle for guidance here. + + PLEASE add the maintainers that are generated by + util/scripts/get_maintainer.pl as reviewers. The results returned + by the script will be best if you have git installed and are + making your changes in a branch derived from coreboot.org's latest + git tree. + + PLEASE try to include any credit lines you want added with the + patch. It avoids people being missed off by mistake and makes + it easier to know who wants adding and who doesn't. + + PLEASE document known bugs. If it doesn't work for everything + or does something very odd once a month document it. + + PLEASE remember that submissions must be made under the terms + of the OSDL certificate of contribution and should include a + Signed-off-by: line. The current version of this "Developer's + Certificate of Origin" (DCO) is listed in the file + Documentation/SubmittingPatches. + +6. Make sure you have the right to send any changes you make. If you + do changes at work you may find your employer owns the patch + not you. + +7. Happy hacking. + +Descriptions of section entries: + + M: Mail patches to: FullName address@domain + R: Designated reviewer: FullName address@domain + These reviewers should be CCed on patches. + L: Mailing list that is relevant to this area + W: Web-page with status/info + Q: Patchwork web based patch tracking system site + T: SCM tree type and location. + Type is one of: git, hg, quilt, stgit, topgit + S: Status, one of the following: + Supported: Someone is actually paid to look after this. + Maintained: Someone actually looks after it. + Odd Fixes: It has a maintainer but they don't have time to do + much other than throw the odd patch in. See below.. + Orphan: No current maintainer [but maybe you could take the + role as you write your new code]. + Obsolete: Old code. Something tagged obsolete generally means + it has been replaced by a better system and you + should be using that. + F: Files and directories with wildcard patterns. + A trailing slash includes all files and subdirectory files. + F: drivers/net/ all files in and below drivers/net + F: drivers/net/* all files in drivers/net, but not below + F: */net/* all files in "any top level directory"/net + One pattern per line. Multiple F: lines acceptable. + N: Files and directories with regex patterns. + N: [^a-z]tegra all files whose path contains the word tegra + One pattern per line. Multiple N: lines acceptable. + scripts/get_maintainer.pl has different behavior for files that + match F: pattern and matches of N: patterns. By default, + get_maintainer will not look at git log history when an F: pattern + match occurs. When an N: match occurs, git log history is used + to also notify the people that have git commit signatures. + X: Files and directories that are NOT maintained, same rules as F: + Files exclusions are tested before file matches. + Can be useful for excluding a specific subdirectory, for instance: + F: net/ + X: net/ipv6/ + matches all files in and below net excluding net/ipv6/ + K: Keyword perl extended regex pattern to match content in a + patch or file. For instance: + K: of_get_profile + matches patches or files that contain "of_get_profile" + K: \b(printk|pr_(info|err))\b + matches patches or files that contain one or more of the words + printk, pr_info or pr_err + One regex pattern per line. Multiple K: lines acceptable. + +Note: For the hard of thinking, this list is meant to remain in alphabetical +order.
