[Alexander Kernozhitsky]

Package: firmware-misc-nonfree
Version: 20190717-2
Severity: normal

Hello,

while invoking update-initramfs -u, I always get a bunch of warnings:

update-initramfs: Generating /boot/initrd.img-5.4.0-3-amd64
W: Possible missing firmware /lib/firmware/i915/icl_dmc_ver1_07.bin for module

W: Possible missing firmware /lib/firmware/i915/tgl_dmc_ver2_04.bin for module
i915
W: Possible missing firmware /lib/firmware/i915/bxt_huc_ver01_8_2893.bin for
module i915

Please include the missing firmware.

Please update the firmware.

I also have these messages but I think they are likely false
positives. There seems to be a lot of possibly misleading information
and advice on the internet about these warnings -- would love to her
your advice on this, but i think these are mostly false positives

* am i right in suspecting that these messages are often false positives?
* why is firmware for processors not present is being warned about?
* is there a way to suppress some of these warnings? (perhaps a
user-defined filter?)
* how do i tell which firmware my processor actually needs?

The longest and most plausible source i have found is [1] but it seems
to miss the point that there is no point installing firmware for a
skylake processor if you don't have one. It also recommends
downloading non-free blobs from intel which may not be the best
solution

The kernel modules arelooked at and list all firmware blobs they might request.

To be able to create 100% complete systems? Not sure...

I am using "dmesg | grep -i firmware" to check what firmware in a running
system is actually loaded into the kernel.
