dsp interface

The dsp interface allows for the control of digital signal processors (DSPs) on specific devices and systems (such as specific Ambarella devices)

Developer details

Auto-connect: no

Note

The dsp plug is unsupported for parallel instances. Instances would perform conflicting operations on the same system resources.

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+.

Code examples

The source code for this interface is in the snapd repository: https://github.com/canonical/snapd/blob/master/interfaces/builtin/dsp.go
