# Binder for Trusty
|
||
|
|
|
||
|
|
This is the Trusty port of the libbinder library.
|
||
|
|
To build it, first you will need a checkout of the Trusty tree:
|
||
|
|
```shell
|
||
|
|
$ mkdir /path/to/trusty
|
||
|
|
$ cd /path/to/trusty
|
||
|
|
$ repo init -u https://android.googlesource.com/trusty/manifest -b master
|
||
|
|
$ repo sync -j$(nproc) -c --no-tags
|
||
|
|
```
|
||
|
|
|
||
|
|
After the checkout is complete, you can use the `build.py` script for both
|
||
|
|
building and testing Trusty. For a quick build without any tests, run:
|
||
|
|
```shell
|
||
|
|
$ ./trusty/vendor/google/aosp/scripts/build.py generic-arm64-test-debug
|
||
|
|
```
|
||
|
|
This will build the smaller `generic-arm64-test-debug` project which
|
||
|
|
does not run any tests.
|
||
|
|
|
||
|
|
The qemu-generic-arm64-test-debug` project includes the QEMU emulator and
|
||
|
|
a full Trusty test suite, including a set of libbinder tests.
|
||
|
|
To run the latter, use the command:
|
||
|
|
```shell
|
||
|
|
$ ./trusty/vendor/google/aosp/scripts/build.py \
|
||
|
|
--test "boot-test:com.android.trusty.binder.test" \
|
||
|
|
qemu-generic-arm64-test-debug
|
||
|
|
```
|
||
|
|
|
||
|
|
## Building AIDL files on Trusty
|
||
|
|
To compile AIDL interfaces into Trusty libraries, include the `make/aidl.mk`
|
||
|
|
in your `rules.mk` file, e.g.:
|
||
|
|
```
|
||
|
|
LOCAL_DIR := $(GET_LOCAL_DIR)
|
||
|
|
|
||
|
|
MODULE := $(LOCAL_DIR)
|
||
|
|
|
||
|
|
MODULE_AIDLS := \
|
||
|
|
$(LOCAL_DIR)/IFoo.aidl \
|
||
|
|
|
||
|
|
include make/aidl.mk
|
||
|
|
```
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
The Trusty tree contains some sample test apps at
|
||
|
|
`trusty/user/app/sample/binder-test`.
