请问MACE运行在DSP上是否必须root手机？

[paulwgw88]

大佬你好，

在MACE文档中看到下面这句
Well, the good news is that starting in the SM8150 family(some devices with old firmware may still not work), signature-free dynamic module offload is enabled on cDSP. So, steps 2-4 can be skipped. This can be achieved by calling SetHexagonToUnsignedPD() before creating MACE engine.

目前我使用的是下面的步骤：

1. yaml文件中设定runtime为dsp
2. 使用文档中Post-training quantization的方法量化模型
3. 使用bazel编译libmace.a，指定runtime为DSP，mace版本为最新的master分支
4. APK链接libmace.a和libhexagon_controller.so
5. 将/third_party/nnlib/v66/libhexagon_nn_skel.so push到手机任意目录
6. 程序中使用setenv设定ADSP_LIBRARY_PATH=“/path/to/libhexagon_nn_skel.so;/system/lib/rfsa/adsp;/system/vendor/lib/rfsa/adsp;/dsp”
7. 调用SetHexagonToUnsignedPD() 和 SetRuntimeType(mace::RT_HEXAGON)设定DSP runtime
8. 载入模型创建engine并执行推理

在三星S10（SM8150）上面可以正常运行在DSP上，但是小米9（SM8150）和一加8T（SM8250）上都无法运行，三台手机都没有root。因为高通Hexagon SDK中的testsig.py执行也需要root手机，所以这步也没有做。

小米9在 MACE_CHECK(hexagon_nn_config() == 0, "hexagon config error"); 这里会出发SIGABRT
一加8T在 MACE_CHECK(hexagon_nn_version(&version) == 0, "get version error"); 这里触发SIGABRT

如果是testsig.py的签名方式，需要root

@lu229 你好，感谢您的答复。
请问对于在DSP上运行MACE推理，使用testsig.py给手机签名这一步是必须的吗？我之前测试使用的三台手机：三星S10、小米9和一加8T，都没有签名过。结果是三星S10可以正常推理，小米9和一加8T不行。

@paulwgw88 how to call SetHexagonToUnsignedPD() before creating mace engine? I need to test dsp functionality on Poco f3(SM8250). Would please elaborate more on that?

Here is my code:

std::shared_ptrmace::MaceEngine mEngine = nullptr;
mace::MaceEngineConfig mEngineConfig;
mEngineConfig.SetHexagonToUnsignedPD();
mEngineConfig.SetRuntimeType(mace::RT_HEXAGON);
mace::MaceStatus status = mace::CreateMaceEngineFromProto(
modelBuffer[0], modelSize[0], modelBuffer[1], modelSize[1],
mInputNames, mOutputNames, mEngineConfig, &mEngine);

Thanks, is it sufficient to use this code along with basic usage tutorial for basic demonstration? https://mace.readthedocs.io/en/latest/user_guide/basic_usage_cmake.html
