1This directory contains the original kernel headers that are used to generate
2Bionic's "cleaned-up" user-land headers.
3
4They are mostly covered by the GPLv2 + exception, and thus cannot be
5distributed as part of the platform itself.
6(NOTE: The cleaned up headers do not contain copyrightable information and are
7distributed with Bionic)
8
9Importing modified kernel headers files is done using scripts found in bionic.

13Generated Headers
14-----------------
15The uapi directory contains uapi version of original kernel headers that are
16used to generate Bionic's "cleaned-up" user-land headers. The script
17bionic/libc/kernel/tools/generate_uapi_headers.sh automatically imports the
18headers from an android kernel repository.
19
20Running the script:
21
22generate_uapi_headers.sh --download-kernel
23
24In order to run the script, you must have properly initialized the build
25environment using the lunch command. The script will automatically retrieve
26an android kernel, generate all include files, and then copy the headers to
27this directory.
28
29The headers are mostly covered by the GPLv2 + exception, and thus cannot be
30distributed as part of the platform itself.
31(NOTE: The cleaned up headers do not contain copyrightable information and
32are distributed with Bionic)

34For more details, please read bionic/libc/kernel/README.TXT
35
36Manually Modified Headers
37-------------------------
38The scsi directory contains a set of manually updated headers. The scsi kernel
39header were never properly made to into uapi versions, so this directory
40contains the unmodified scsi headers that are imported into bionic. The
41generation script will indicate if these files have changed and require
42another manual update.
43
44The files from the scsi directory will be copied into bionic after being
45processed as is, unless there exists a file of the same name in
46../modified/scsi. Any files found in the modified directory completely
47replace the ones in the scsi directory.
