| 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. | 
| Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 6 |  | 
| 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. |

|  | 12 |  | 
| 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. | 
| Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 44 |  | 
| Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame] | 45 | 12: Has been tested with CONFIG_PREEMPT, CONFIG_DEBUG_PREEMPT, | 
|  | 46 | CONFIG_DEBUG_SLAB, CONFIG_DEBUG_PAGEALLOC, CONFIG_DEBUG_MUTEXES, | 
|  | 47 | CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_SPINLOCK_SLEEP all simultaneously | 
|  | 48 | enabled. | 
| Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 49 |  | 
| Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame] | 50 | 13: Has been build- and runtime tested with and without CONFIG_SMP and | 
|  | 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. | 
| Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 55 |  | 
| Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame] | 56 | 15: All codepaths have been exercised with all lockdep features enabled. | 
| Randy Dunlap | 915a56d | 2006-06-23 02:05:49 -0700 | [diff] [blame] | 57 |  | 
| Andrew Morton | e54695a | 2006-07-10 04:45:42 -0700 | [diff] [blame] | 58 | 16: All new /proc entries are documented under Documentation/ | 
|  | 59 |  | 
|  | 60 | 17: All new kernel boot parameters are documented in | 
|  | 61 | Documentation/kernel-parameters.txt. | 
|  | 62 |  | 
|  | 63 | 18: All new module parameters are documented with MODULE_PARM_DESC() |
