The dsp interface allows for the control of digital signal processors (DSPs) on specific devices and systems (such as specific Ambarella devices)
Interface documentation: See Interface management and Supported interfaces for further details on how interfaces are used.
Developer details
Auto-connect: no
This interface allows privileged access to hardware and kernel drivers related to the digital signal processor and thus is only allowed on specific devices providing the slot via a gadget and is also not auto-connected.
Requires snapd version 2.51+.
