Wow. Run-time changes and discoverability? This sounds wild. what type
of solutions are we talking about here?
All the DSP implementations I've seen are pretty dumb, the firmware is
downloaded at the request of the host when a specific service is
requested; discoverability isn't an issue since the driver and
possibly user-space know what's been downloaded and how the downloaded
parts interact with the rest of the firmware.
