mehrdadh opened a new pull request #9631:
URL: https://github.com/apache/tvm/pull/9631
This PR:
- Reuses minRPC implementation for hexagon to create RPC connection from
host to hexagon device which is passed through android RPC server.
- Adds HexagonLauncher which manages file upload to Android, initiate RPC
server on Android and manage RPC session to hexagon.
To use this feature you need to build TVM using these configs:
```
cmake -DUSE_HEXAGON_RPC=ON \
-DUSE_ANDROID_TOOLCHAIN=/path/to/android-ndk/build/cmake/android.toolchain.cmake
\
-DANDROID_PLATFORM=android-28 \
-DANDROID_ABI=arm64-v8a \
-DUSE_HEXAGON_ARCH=v65|v66|v68 \
-DUSE_HEXAGON_SDK=/path/to/Hexagon/SDK \
-DUSE_HEXAGON_TOOLCHAIN=/path/to/Hexagon/toolchain/ \
-DUSE_LLVM=/path/to/llvm/bin/llvm-config \
-DUSE_CPP_RPC=ON \
-DCMAKE_CXX_COMPILER=/path/to/clang++ \
-DCMAKE_CXX_FLAGS='-stdlib=libc++' ..
```
This will build:
- `libtvm` and `libtvm_runtime` using hexagon LLVM and`tvm_rcp` for **host**.
- `libtvm_runtime_android.so` and `tvm_rpc_android` for **Android** under
`build/hexagon_rpc`
- `libhexagon_rpc_skel.so` library which include RPC server for **Hexagon**
under `build/hexagon_rpc`
