| # `aarch64-unknown-teeos` | ||
|
|
||
| **Tier: 3** | ||
|
|
||
| Target for the TEEOS operating system. | ||
|
|
||
| TEEOS is a mini os run in TrustZone, for trusted/security apps. The kernel of TEEOS is HongMeng/ChCore micro kernel. The libc for TEEOS is a part of musl. | ||
| It's very small that there is no RwLock, no network, no stdin, and no file system for apps in TEEOS. | ||
|
|
||
| Some abbreviation: | ||
| | Abbreviation | The full text | Description | | ||
| | ---- | ---- | ---- | | ||
| | TEE | Trusted Execution Environment | ARM TrustZone devide the system into two worlds/modes -- the secure world/mode and the normal world/mode. TEE is in the secure world/mode. | | ||
| | REE | Rich Execution Environment | The normal world. for example, Linux for Android phone is in REE side. | | ||
| | TA | Trusted Application | The app run in TEE side system. | | ||
| | CA | Client Application | The progress run in REE side system. | | ||
|
|
||
| TEEOS is open source in progress. [MORE about](https://gitee.com/opentrustee-group) | ||

||
| ## Target maintainers | ||
|
|
||
| - Petrochenkov Vadim | ||
| - Sword-Destiny | ||
|
|
||
| ## Setup | ||
| We use OpenHarmony SDK for TEEOS. | ||
|
|
||
| The OpenHarmony SDK doesn't currently support Rust compilation directly, so | ||
| some setup is required. | ||
|
|
||
| First, you must obtain the OpenHarmony SDK from [this page](https://gitee.com/openharmony/docs/tree/master/en/release-notes). | ||
| Select the version of OpenHarmony you are developing for and download the "Public SDK package for the standard system". | ||
|
|
||
| Create the following shell scripts that wrap Clang from the OpenHarmony SDK: | ||
|
|
||
| `aarch64-unknown-teeos-clang.sh` | ||
|
|
||
| ```sh | ||
| #!/bin/sh | ||
| exec /path/to/ohos-sdk/linux/native/llvm/bin/clang \ | ||
| --target aarch64-linux-gnu \ | ||
| "$@" | ||
| ``` | ||
|
|
||
| `aarch64-unknown-teeos-clang++.sh` | ||
|
|
||
| ```sh | ||
| #!/bin/sh | ||
| exec /path/to/ohos-sdk/linux/native/llvm/bin/clang++ \ | ||
| --target aarch64-linux-gnu \ | ||
| "$@" | ||
| ``` | ||
|
|
||
| ## Building the target | ||
|
|
||
| To build a rust toolchain, create a `config.toml` with the following contents: | ||
|
|
||
| ```toml | ||
| profile = "compiler" | ||
| changelog-seen = 2 | ||
|
|
||
| [build] | ||
| sanitizers = true | ||
| profiler = true | ||
| target = ["x86_64-unknown-linux-gnu", "aarch64-unknown-teeos"] | ||
| submodules = false | ||
| compiler-docs = false | ||
| extended = true | ||
|
|
||
| [install] | ||
| bindir = "bin" | ||
| libdir = "lib" | ||
|
|
||
| [target.aarch64-unknown-teeos] | ||
| cc = "/path/to/scripts/aarch64-unknown-teeos-clang.sh" | ||
| cxx = "/path/to/scripts/aarch64-unknown-teeos-clang.sh" | ||
| linker = "/path/to/scripts/aarch64-unknown-teeos-clang.sh" | ||
| ar = "/path/to/ohos-sdk/linux/native/llvm/bin/llvm-ar" | ||
| ranlib = "/path/to/ohos-sdk/linux/native/llvm/bin/llvm-ranlib" | ||
| llvm-config = "/path/to/ohos-sdk/linux/native/llvm/bin/llvm-config" | ||
| ``` | ||
|
|
||
| ## Building Rust programs | ||
|
|
||
| Rust does not yet ship pre-compiled artifacts for this target. To compile for | ||
| this target, you will either need to build Rust with the target enabled (see | ||
| "Building the target" above), or build your own copy of `core` by using | ||
| `build-std` or similar. | ||
|
|
||
| You will need to configure the linker to use in `~/.cargo/config`: | ||
| ```toml | ||
| [target.aarch64-unknown-teeos] | ||
| linker = "/path/to/aarch64-unknown-teeos-clang.sh" | ||
| ``` | ||
|
|
||
| ## Testing | ||
|
|
||
| Running the Rust testsuite is not possible now. | ||
|
|
||
| More information about how to test CA/TA. [See here](https://gitee.com/openharmony-sig/tee_tee_dev_kit/tree/master/docs) |
