1 | # Kernel |
| 2 | ||
| 3 | ## Configuration | |
| 4 | ||
| 5 | ### Layout | |
| 6 | ||
| 7 | The kernel configuration files are split into individual configuration files for | |
| 8 | each architecture. This way, common options can be changed globally and can be | |
| 9 | overwritten for certain architectures which gives us a more consistent configuration | |
| 10 | across all architectures. | |
| 11 | ||
| 12 | ### How to update the configuration? | |
| 13 | ||
| 14 | For these steps, you will have to change into a build environment and change to | |
| 15 | the kernel directory: | |
| 16 | ||
| 17 | # pakfire-builder shell kernel.nm | |
| 18 | (pakfire-shell)> cd /usr/src/packages/kernel-x.y.z... | |
| 19 | ||

20 | The following commands are available. Appending the <arch> argument allows you |
| 21 | to edit a specific architecture. Default is x86_64. | |

22 | |
| 23 | #### oldconfig | |
| 24 | ||
| 25 | You can run this when updating the kernel to a new release or after changing any | |
| 26 | options manually. All unset or updated options will be prompted for and all | |
| 27 | configuration files for all architectures will be updated. | |
| 28 | ||
| fa4b3a6b | 29 | (pakfire-shell)> scripts/configure oldconfig <arch> |
| 4556c20a MT |
30 | |
| 31 | #### olddefconfig | |
| 32 | ||
| 33 | Like oldconfig, but automatically answers all options with the default value. | |
| 34 | ||
| 35 | (pakfire-shell)> scripts/configure olddefconfig | |
| 36 | ||
| 37 | #### menuconfig | |
| 38 | ||

39 | If you want to edit the configuration using the kernel's config editor. All |
| 40 | configuration files will be updated afterwards and potentially prompted for options | |
| 41 | that diverge for different architectures. | |
| 4556c20a | 42 | |
| fa4b3a6b | 43 | (pakfire-shell)> scripts/configure menuconfig <arch> |
| a8e51819 | 44 | |
| 4556c20a MT |
45 | #### listnewconfig |
| 46 | ||
| 47 | This will list all unset options. | |
| 48 | ||
| fa4b3a6b | 49 | (pakfire-shell)> scripts/configure listnewconfig <arch> |
