[Hexagon] running model on hexagon cdsp getting "undefined symbol" error

Troubleshooting
1

Hi all, I’m trying to run a simple model on hexagon dsp following these step to build “launcher_android” and “libtvm_runtime.so”:

cmake -DCMAKE_TOOLCHAIN_FILE="/data00/android-ndk-r25c/build/cmake/android.toolchain.cmake"
-DANDROID_ABI=arm64-v8a
-DANDROID_PLATFORM=android-28
-DUSE_HEXAGON_SDK="/data00/5.3.0.0"
-DUSE_HEXAGON_ARCH=v68
-DCMAKE_CXX_STANDARD=17
-DTVM_LOG_CUSTOMIZE=1
/data00/tvm/apps/hexagon_launcher/cmake/android
&& make -j8

and for “liblauncher_rpc_skel.so” I use:

cmake -DCMAKE_C_COMPILER="/data00/ziyeyang/5.3.0.0/tools/HEXAGON_Tools/8.6.06/Tools/bin/hexagon-clang"
-DCMAKE_CXX_COMPILER="/data00/5.3.0.0/tools/HEXAGON_Tools/8.6.06/Tools/bin/hexagon-clang++"
-DUSE_HEXAGON_ARCH=v68
-DUSE_HEXAGON_SDK="/data00/5.3.0.0"
-DCMAKE_CXX_STANDARD=17
-DTVM_LOG_CUSTOMIZE=1
/data00/tvm/apps/hexagon_launcher/cmake/hexagon
&& make -j8

when I trying to run on device using: /launcher_android --in_config gan_input.json --out_config output.json

got the following error: error loading graph module: 4e

and in logcat:

Does anyone knows how to solve this? thanks in advance

When you load a compiled model using dlopen (as the launcher_android does), there are usually some undefined symbol references in it, but they are generally harmless. This especially applies to the double-underscored symbols like __TVMBackendAllocWorkspace. I’m not sure about the _lookup_linked_param though.

How did you build the model? Did you use the AoT executor?

Edit: Could you post more output from logcat? Especially the output leading to the error 4e?

We didn’t use the AoT actuator, would it make a difference? The steps to build the model refer to tvm/apps/hexagon_launcher at main · apache/tvm · GitHub. A very simple onnx model with fixed I/O shape. The full log is as follows:

Our execution environment can be downloaded here(http://43.138.42.59:32666/dsp.zip), including model, so libraries and launcher_android.
Our execution steps here:

adb push dsp /data/local/tmp
adb shell
cd /data/local/tmp/dsp
source set_path.sh
./launcher_android --in_config linear_input.json --out_config output.json

In fact, we want to let the model inference on adsp, but it seems that hxv is used when AOT uses hexagon as the target according to

aot_target = "llvm -keys=hexagon -mattr=+hvxv69,+hvx-length128b,+hvx-qfloat,-hvx-ieee-fp -mcpu=hexagonv69 -mtriple=hexagon"
aot_host_target = aot_target

which is only supported on cdsp? Is this optional? Could you give some advice about inference model on adsp?

Sorry, forgot about this one. We are currently assuming CDSP with HVX.

I meet the same problem. I solve this by AoT executor
