VNDK Definition Tool
====================
## Usage
Create a generic reference symbols from AOSP build:
$ python3 vndk_definition_tool.py create-generic-ref \
-o generic_arm64/system \
${OUT_DIR_COMMON_BASE}/target/product/generic_arm64/system
Run the VNDK definition tool with:
$ python3 vndk_definition_tool.py vndk \
--system ${ANDROID_PRODUCT_OUT}/system \
--vendor ${ANDROID_PRODUCT_OUT}/vendor \
--load-generic-refs generic_arm64
This command will give you three different lists:
- vndk-core: VNDK libraries that are both used by frameworks and HALs. This
set will be installed on system partition.
- vndk-indirect: VNDK libraries that are indirectly used by vndk-core but
not directly used by vendors. This set will be installed on system partition.
- vndk-ext: VNDK libraries that are both used by frameworks and HALs. This set
is for the libraries that do not have an functionally-equivalent AOSP
counterpart. This set will be installed on vendor partition.
# Sub Directory Tagging
If there are some sub directory under system partition must be treated as
vendor files, then specify such directory with: `--system-dir-as-vendor`.
Conversely, if there are some sub directory under vendor partition must be
treated as system files, then specify such directory with:
`--vendor-dir-as-system`.
For example, if the device does not have an independent `vendor` partition (but
with a `vendor` folder in the `system` partition), then run this command:
$ python3 vndk_definition_tool.py vndk \
--system ${ANDROID_PRODUCT_OUT}/system \
--system-dir-as-vendor vendor \
--load-generic-refs generic_arm64
For example, if `/system/bin/hw`, `/system/lib/hw`, and `/system/lib64/hw` are
containing vendor files, then run this command:
$ python3 vndk_definition_tool.py vndk \
--system ${ANDROID_PRODUCT_OUT}/system \
--system-dir-as-vendor bin/hw \
--system-dir-as-vendor lib/hw \
--system-dir-as-vendor lib64/hw \
--vendor ${ANDROID_PRODUCT_OUT}/vendor \
--load-generic-refs generic_arm64
## Implicit Dependencies
If there are implicit dependencies, such as `dlopen()`, we can specify them in
a dependency file and load the dependency file with `--load-extra-deps`. The
dependency file format is simple: (a) each line stands for a dependency, and
(b) the file before the colon depends on the file after the colon. For
example, `libart.so` depends on `libart-compiler.so`:
/system/lib64/libart.so: /system/lib64/libart-compiler.so
And then, run VNDK definition tool with:
$ python3 vndk_definition_tool.py vndk \
--system ${ANDROID_PRODUCT_OUT}/system \
--vendor ${ANDROID_PRODUCT_OUT}/vendor \
--load-generic-refs generic_arm64 \
--load-extra-deps dlopen.dep
## Warnings
### Incorrect Partition
If you specify `--warn-incorrect-partition` command line option, then VNDK
definition tool will emit warnings when:
1. A framework library is only used by vendor binaries.
2. A vendor library is only used by framework binaries.
This allows people to review the correct partition for the module. For example,
warning: /system/lib/libtinyxml.so: This is a framework library with
vendor-only usages.
warning: /system/lib64/libtinyxml.so: This is a framework library with
vendor-only usages.
These warnings suggest that `libtinyxml.so` might be better to move to vendor
partition.
### VNDK Extension
If you specify `--load-generic-refs`, then you may see some warnings:
warning: /system/lib/libhardware_legacy.so: This is a VNDK extension and
must be moved to vendor partition.
This warning indicates that the library is not in the generic reference or the
library contains some symbols that are not available in generic build. It must
be installed into vendor partition instead. As the result, it will be included
in vndk-ext.
## Example
We can run this against Nexus 6p Factory Image:
$ unzip angler-nmf26f-factory-ef607244.zip
$ cd angler-nmf26f
$ unzip image-angler-nmf26f.zip
$ simg2img system.img system.raw.img
$ simg2img vendor.img vendor.raw.img
$ mkdir system
$ mkdir vendor
$ sudo mount -o loop,ro system.raw.img system
$ sudo mount -o loop,ro vendor.raw.img vendor
$ sudo python3 vndk_definition_tool.py vndk \
--system system --vendor vendor
We can run this against latest Android build:
$ python3 vndk_definition_tool.py vndk \
--system ${ANDROID_PRODUCT_OUT}/system \
--system-dir-as-vendor bin/hw \
--system-dir-as-vendor lib/hw \
--system-dir-as-vendor lib64/hw \
--vendor ${ANDROID_PRODUCT_OUT}/vendor
## Python 2 Support
Since `vndk_definition_tool.py` runs 3x faster with Python 3, the shebang is
specifying `python3` by default. To run `vndk_definition_tool.py` with
python2, run the following command:
$ python vndk_definition_tool.py [options]
