But to answer you question: I doubt it will have anything to do with QEMU since this is just the driver, firmware and SDK for Intel audio hardware.

Double plus good if they take the extra step and put up a bug tracker for people to submit bug reports. Instead of being an unknown it would help with both threat modeling, and patching bugs, a real big win for security.

I do that with my bios and me-cleaner. the bios chip is socketed, labeled in big bold letters, and a basic USB flasher that works with flashrom can be had on amazon for under $10. I also have a plugin cable where I can use a clamp to program/dump roms in place. That was another $5 on amazon.

It sounds like mostly getting free eyeballs at the problem. Since they use a BSD-like license, it's a small step. But opening up the DSP firmware, I'll tip my hat to Intel. A lot of what we do is brute-forcing our way in the darkness, so I'll take any inch I can take. Thank you Intel.

It's just not recommended to do so because if the modification screws up the PC you are marooned.
But most deployments have multiples of the same model of PC, so if the manual procedure works fine on one or two guinea pig PCs you can mass-deploy on any other PC that is exactly the same, because mass-production means they are the same.

I wondered why SOFproject links to alsa-project.org, it turns out the Firmware wiki page there has details of the architecture with useful diagrams. And sound-open-firmware-tools.git is part of Alsa-project.git!
Intel should have put the documentation and software inside the pulseaudio project, just to mess with people.
