| | 18 | ### Kernel .config Creation |
|---|
| | 19 | # The following target combines all kernel-related variables and |
|---|
| | 20 | # config files into a single one to be used as the final kernel |
|---|
| | 21 | # configuration when building. This is how it's done: |
|---|
| | 22 | # 1) fetch all FWRT_KPACKAGE_KMOD_* vars into |
|---|
| | 23 | # .fwrtkernelconfig.modules and set them to "m" |
|---|
| | 24 | # 2) fetch all enabled FWRT_KERNEL_* vars into |
|---|
| | 25 | # .fwrtkernelconfig.kernel (no conversion, as they are booleans) |
|---|
| | 26 | # 3) repeat 2) for the disabled ones and save them into |
|---|
| | 27 | # .fwrtkernelconfig.nokernel (for some obscure reason) |
|---|
| | 28 | # 4) get the board-specific static kernel config and place it into |
|---|
| | 29 | # .fwrtkernelconfig.board |
|---|
| | 30 | # 5) prepare for merging: |
|---|
| | 31 | # * if a variable is disabled in .fwrtkernelconfig.board and |
|---|
| | 32 | # enabled in either of .fwrtkernelconfig.{modules,kernel}, |
|---|
| | 33 | # remove it from .fwrtkernelconfig.board |
|---|
| | 34 | # * append ${FS_CMDLINE} to the kernel commandline inside |
|---|
| | 35 | # .fwrtkernelconfig.board |
|---|
| | 36 | # 6) merge (cat) it all together into .fwrtkernelconfig.tmp |
|---|
| | 37 | # 7) check if .fwrtkernelconfig.tmp differs from the current one |
|---|
| | 38 | # (.fwrtkernelconfig) at all, overwriting the current one |
|---|
| | 39 | # only if it does (so the timestamp stays intact) |
|---|
| | 40 | # 8) remove the temporary .fwrtkernelconfig.tmp |
