Re: Regarding implementing sof-firmware in GUIX.

Hello Tobias,

> * gnu/packages/firmware.scm (sof): New public variable.

Thanks for the package definition. Last time I checked, some devices
required signed firmware:

--8<---------------cut here---------------start------------->8---
The firmware file, /lib/firmware/intel/sof/sof-tgl.ri, contains all DSP
code and tables. On PCI devices, the firmware can only be signed by an
Intel production key which prevents community users from installing
their own firmware. Notable exceptions include Google Chromebooks and
Up2/Up-Extreme boards, where the community key is used.
--8<---------------cut here---------------end--------------->8---

I'm not sure what's the point of letting users build their firmware if
it cannot be loaded. Looks like multiple projects are in fact packaging
the signed sof firmware, which is non-free[2].

Thanks,

Mathieu
