| This directory contains the original kernel headers that are used to generate |
| Bionic's "cleaned-up" user-land headers. |
| |
| They are mostly covered by the GPLv2 + exception, and thus cannot be |
| distributed as part of the platform itself. |
| (NOTE: The cleaned up headers do not contain copyrightable information and are |
| distributed with Bionic) |
| |
| Importing modified kernel headers files is done using scripts found in bionic. |

| Generated Headers |
| ----------------- |
| The uapi directory contains uapi version of original kernel headers that are |
| used to generate Bionic's "cleaned-up" user-land headers. The script |
| bionic/libc/kernel/tools/generate_uapi_headers.sh automatically imports the |
| headers from an android kernel repository. |
| |
| Running the script: |
| |
| generate_uapi_headers.sh --download-kernel |
| |
| In order to run the script, you must have properly initialized the build |
| environment using the lunch command. The script will automatically retrieve |
| an android kernel, generate all include files, and then copy the headers to |
| this directory. |
| |
| The headers are mostly covered by the GPLv2 + exception, and thus cannot be |
| distributed as part of the platform itself. |
| (NOTE: The cleaned up headers do not contain copyrightable information and |
| are distributed with Bionic) |
| |
| For more details, please read bionic/libc/kernel/README.TXT |
| |
| Manually Modified Headers |
| ------------------------- |
| The scsi directory contains a set of manually updated headers. The scsi kernel |
| header were never properly made to into uapi versions, so this directory |
| contains the unmodified scsi headers that are imported into bionic. The |
| generation script will indicate if these files have changed and require |
| another manual update. |
| |
| The files from the scsi directory will be copied into bionic after being |
| processed as is, unless there exists a file of the same name in |
| ../modified/scsi. Any files found in the modified directory completely |
| replace the ones in the scsi directory. |
