+# Test TVM on Hexagon
+This document explains various pieces that are involved in testing TVM on an Android device which includes Hexagon DSP or Hexagon simulator.
+
+## What is HexagonLauncherRPC?
+HexagonLauncherRPC is a class to handle interactions with an Android phone which includes Hexagon DSP or Hexagon simulator to run a TVMModule(function/operation/graph) on Hexagon. HexagonLauncherRPC reuses [minRPC](https://github.com/apache/tvm/tree/main/src/runtime/minrpc) implementation to set up an RPC connection from host (your local machine) to Hexagon target, and it is passed through Android RPC server.
+
+## Build Required Tools/Libraries
+To build TVM for Hexagon and run tests you need to run multiple steps which includes preparing required tools, setup environment variables and build various versions of TVM. Alternatively, you can skip these instructions and use docker image which has pre-installed required tools. We highly recommend to use docker, specially if this is your first time working with Hexagon. For instructions on using docker image follow ["use hexagon docker image"](#use-hexagon-docker-image).
+
+- Build TVMRuntime library and C++ RPC server for Android.
+- Build minRPC server along with FastRPC for Hexagon.
+- Build TVM library with Hexagon support for host machine.
+- Build TVMRuntime library and RPC server for host machine.
+
+First, ensure to export Clang libraries to `LD_LIBRARY_PATH` and Hexagon toolchain to `HEXAGON_TOOLCHAIN`:
+```bash
+export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"path to `llvm-clang/lib` sub-directory"
+
+export HEXAGON_TOOLCHAIN="Path to Hexagon toolchain. It can be the Hexagon toolchain included in the SDK, for example `HEXAGON_SDK_PATH/tools/HEXAGON_Tools/x.y.z/Tools`. The `x.y.z` in the path is the toolchain version number, which is specific to the version of the SDK."
+```
+
+First build Hexagon API application under `apps/hexagon_api`. This step will generate `tvm_rpc_android` and `libtvm_runtime.so` to run on Android. Also, it generates `libtvm_runtime.a` `libtvm_runtime.so`, `libhexagon_rpc_skel.so` and `libhexagon_rpc_sim.so` to run on Hexagon device or Hexagon simulator.
+
+**Note:** To get the most updated instructions, please take a look at [task_build_hexagon_api.sh](https://github.com/apache/tvm/blob/main/tests/scripts/task_build_hexagon_api.sh).
Review Comment:
This link is broken in the markdown preview. Probably just because this is not merged, but mentioning just in case.

+
+```bash
+cd apps/hexagon_api
+mkdir build
+cd build
+cmake -DANDROID_ABI=arm64-v8a \
+ -DANDROID_PLATFORM=android-28 \
+ -DUSE_ANDROID_TOOLCHAIN="path to `android-ndk/build/cmake/android.toolchain.cmake` file" \
+ -DUSE_HEXAGON_ARCH=v65|v66|v68|v69 \
+ -DUSE_HEXAGON_SDK="path to Hexagon SDK" \
+ -DUSE_HEXAGON_TOOLCHAIN="path to Hexagon toolchain `Tools` sub-directory which explained above" \
+ -DUSE_OUTPUT_BINARY_DIR="path to `build/hexagon_api_output` which is a sub-directory of `tvm`" ..
+
+make -j2
+```
+
+Next, we need to build TVM on host with RPC and Hexagon dependencies. To do that follow these commands.
+
+**Note:** To get the most recent configs for this step, please take a look at [task_config_build_hexagon.sh](https://github.com/apache/tvm/blob/main/tests/scripts/task_config_build_hexagon.sh).
+
+```bash
+cd tvm
+mkdir build
+cd build
+cmake -DUSE_LLVM="path to `llvm/bin/llvm-config`" \
+ -DUSE_RPC=ON \
+ -DCMAKE_CXX_COMPILER="path to `clang++` executable" \
+ -DUSE_HEXAGON_SDK="path to Hexagon SDK" \
+ -DUSE_HEXAGON=ON ..
+
+make -j2
+```
+
+## Use Hexagon Docker Image
+To use hexagon docker image, install TVM and Hexagon API follow these steps.
+
+```bash
+# Log in to docker image
+cd tvm
+./docker/bash.sh ci_hexagon
+
+# Build TVM
+./tests/scripts/task_config_build_hexagon.sh
+cd build
+cmake ..
+make -j2
+
+# Build Hexagon API
+cd ..
+./tests/scripts/task_build_hexagon_api.sh
+```
+
+Now that you have built required tools, you can jump to [run test examples](#run-tests).
