Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 4 | Here are some basic things that developers should do if they want to see their |
| 5 | kernel patch submissions accepted more quickly. |

Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 7 | These are all above and beyond the documentation that is provided in |
| 8 | Documentation/SubmittingPatches and elsewhere regarding submitting Linux |
| 9 | kernel patches. |

Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 13 | 1: Builds cleanly with applicable or modified CONFIG options =y, =m, and |
| 14 | =n. No gcc warnings/errors, no linker warnings/errors. |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 15 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 16 | 2: Passes allnoconfig, allmodconfig |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 17 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 18 | 3: Builds on multiple CPU architectures by using local cross-compile tools |
| 19 | or something like PLM at OSDL. |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 20 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 21 | 4: ppc64 is a good architecture for cross-compilation checking because it |
| 22 | tends to use `unsigned long' for 64-bit quantities. |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 23 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 24 | 5: Matches kernel coding style(!) |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 25 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 26 | 6: Any new or modified CONFIG options don't muck up the config menu. |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 27 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 28 | 7: All new Kconfig options have help text. |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 29 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 30 | 8: Has been carefully reviewed with respect to relevant Kconfig |
| 31 | combinations. This is very hard to get right with testing -- brainpower |
| 32 | pays off here. |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 33 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 34 | 9: Check cleanly with sparse. |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 35 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 36 | 10: Use 'make checkstack' and 'make namespacecheck' and fix any problems |
| 37 | that they find. Note: checkstack does not point out problems explicitly, |
| 38 | but any one function that uses more than 512 bytes on the stack is a |
| 39 | candidate for change. |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 40 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 41 | 11: Include kernel-doc to document global kernel APIs. (Not required for |
| 42 | static functions, but OK there also.) Use 'make htmldocs' or 'make |
| 43 | mandocs' to check the kernel-doc and fix any issues. |

| 46 | CONFIG_DEBUG_SLAB, CONFIG_DEBUG_PAGEALLOC, CONFIG_DEBUG_MUTEXES, |
| 47 | CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_SPINLOCK_SLEEP all simultaneously |
| 48 | enabled. |

| 51 | CONFIG_PREEMPT. |
Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 52 | |
Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame^] | 53 | 14: If the patch affects IO/Disk, etc: has been tested with and without |
| 54 | CONFIG_LBD. |
