You need an equivalent of the library found in the Android releases, this provides the means of loading your executable into the DSP and invoking method calls on it, through the FastRPC service.

There’s been some progress on this for non-Android lately, but unfortunately we do not yet support this feature.

Thanks for the answer.
How can we use the DSP from Debian before the equivalent of the

I presume that “use the DSP” means “use the DSP to offload my custom algorithm” and if so the only alternative is to acquire the DSP source code from Qualcomm, integrate your feature and rebuild the DSP binaries.
