I am triying to use the DSP hardware for inference using the snpe-net-run exec.

My hardware is the Snapdragon 888 Mobile Hardware Development Kit. However when running snpe-net-run we get the following error:

```

$ snpe-net-run --container model_quant.dlc --input_list random_files_list.txt --output_dir output --use_dsp
 
The selected runtime is not available on this platform. Continue anyway to observe the failure at network creation time.
error_code=500; error_message=Target runtime is not available. error_code=500; error_message=Target runtime is not available. No viable runtimes available.; error_component=Host Runtime; line_no=409; thread_id=496697900288; error_component=Host Runtime; line_no=265; thread_id=509381006584

```

I used the snpe-platform-validator to validate that the DSP hardware is indeed available:

```

$ ../../snpeexample/aarch64-android-clang6.0/bin/snpe-platform-validator --runtime all

```

Is there a special setup required for this kind of development board? BTW CPU and GPU runtimes work properly.

thanks

Apperently the DSP system files could be access only with root permission.

Wrapping the command with `su 0` works as follow:

$ su 0 snpe-net-run --container model_quant.dlc --input_list random_files_list.txt --output_dir output --use_dsp
 
Unfortunately some great tools like the snpe_bench.py use as `sh` hardcoded and I can't see if it is possible to run the commands as root.
Is there an option to run snpe_bench.py as root, or somehow make the DSP system files accessable to non root?
