What exactly is "Unsigned PD"?

And where are all of the userspace changes for this series so we can
verify they work properly?

Hi Greg,
Unsigned PDs are sandboxed DSP processes used to offload computation
workloads to the DSP. Unsigned PD have less privileges in terms of
DSP resource access as compared to Signed PD.

Unsigned PD can be enabled using userspace API:

For multimode invoke request(other feature) also I've shared the
userspace changes with Srini which he will be pulling to userspace

Please let me know if you have any other queries.
