Firmware is needed by a lot of modern devices.
Includes various radio interfaces, GPU and CPU stuff.
Due to the large space required by some firmwares as a whole,
compression can optionally be enabled.

Hmmm, I'm not sure about this. I've always dumped selected firmware files
and their license into projectroot/ and created a local package. Mostly for
two reasons:
1. I wanted the fine control to explicitly update individual firmware
files.
2. I never found a good way to split the package options. For example,
installing all iwlwifi* files seems excessive but so does adding an option
for each on.
Any other opinions on this?

I can share some experience from the fli4l [1] project, but from a
different viewing angle. Most firmware is not free in a FOSS licensed
way, so it's hard to find a generic solution, especially when getting
the license stuff right. That's why we opted for free (as in under
FOSS license) firmware only, which means: user is responsible for
handling non-free firmware.
Same thing basically applies for proprietary firmware you develop yourself.
So I think the approach Michael suggested in this case is a useful
one: just put the few blobs and license stuff you need into your BSP.
This obviously would not work if the user can plug arbitrary hardware
like WiFi cards, but if hardware is restricted, and most embededded
projects are (?), then this is no problem.
However if you don't have control which additional hardware your users
plug, and you still want to support it, you would need a more generic
approach.

Hi.
I think I can clarify my raison d'être a bit.
The kernel isn't overly informative on what it is loading or has loaded
(history) as a default. I patch the firmware class or use dyndbg to get
all the loaded firmware files from this standard package. From time to
time things can be a little bit non-obvious, such as the Raven Ridge APU
requiring a blob named Raven2-something.
So I usually end up providing all the blobs (names do change) with the
latest firmware package, get all the files when I'm happy with the
configuration and filter it down. Because the whole package is rather huge.
So for my part, I still have to provide linux-firmware bits and that I
partly go through the same thing anyway.
I agree that the *.in is rather non-optimal, but I'm open to
suggestions. Maybe an *all* and a *filter list* once you're done is better?
Regards,
Christian

Bump.
No more opinions? Go? No go? Changes?

Hi
Thanks for submitting the first suggestion on an upstream linux-firmware rule.
I don't have the answer to what is the right solution.
It could be a menu selection as you suggested or it could be wildcard
input fields.
I know that each firmware can be under different license but that
could be solved
in the linux-firmware.make file where the menu selection like
LINUX_FIRMWARE_AMDGPU
just add the correct license to LINUX_FIRMWARE_LICENSE variable. And in case
multiple firmware options are enabled just append them.

All and a filter makes sense. How about this:
Install with install_glob and use * as default glob. Allow custom globs
from the config.
List all licenses in LINUX_FIRMWARE_LICENSE_FILES. Use a config option to
allow listing just the file names, and then:
LINUX_FIRMWARE_SELECTED_LICENCES := $(call remove_quotes, PTXCONF_LINUX_FIRMWARE_LICENCES)
ifneq ($(LINUX_FIRMWARE_SELECTED_LICENCES),)
LINUX_FIRMWARE_LICENSE_FILES := $(filter $(addsuffix %,$(addprefix file://,$(LINUX_FIRMWARE_SELECTED_LICENCES))),$(LINUX_FIRMWARE_LICENSE_FILES))
endif

Hi Michael,
I need to get back to this and get it sorted.
Trying to figure out what you are suggesting here.
Sorry, being a bit slow now. :)
There is no strict relation between firmware file names and licence file
names beside some random name resemblance.
I don't understand how you suggest I pick the license files
from the firmware file names?
Or do you mean that one should choose licenses from a long list of tick
options for ptxdist to filter into the used ones?
That plus manually selecting the actual firmware files.
Regards,
Christian
