libcamera is an open source camera stack and framework for Linux, Android,
and ChromeOS.
Since libcamera is still quite new and there are no released versions yet,
a git snapshot is used.
A patch is currently required to deactivate the automatic git-based version
generation, otherwise the git information from the BSP repository will be
used incorrectly. This may lead to a build error, at least to an incorrect
version.
However, since libcamera versioning is currently being discussed, the patch
may be dropped in the near future.
Changelog:
v2:
- Changed format of git version tag
- Use list-based processing for IPAs
- Add a comment to note why IPA modules are not stripped
- Some source format fixes

+Subject: [PATCH] do not use git information for version generation
+
+Since libcamera is checked out without a git repo, git version reports the
+version of the BSP. Since this is obviously wrong, just use the project
+version.

Hi Matthias,
thanks for working on this, I also have a libcamera package here :) and
want to share a few findings.

I would provide the user the choice of selecting/enabling the ipa module
signing.
config LIBCAMERA_IPA_MODULE_SIGN

default y
prompt "Enable IPA module signing"
help
Without IPA module signing, all IPA modules will be isolated in a
separate process. This adds an unnecessary extra overhead at runtime.
if LIBCAMERA_IPA_MODULE_SIGN
choice
prompt "Crypt provider"
default LIBCAMERA_IPA_MODULE_SIGN_GNUTLS
config LIBCAMERA_IPA_MODULE_SIGN_GNUTLS

So, I missed this in the first version: Why would someone enable (for

pipeline (or whichever is available)?

Hmmm, what would be the benefit of making this optional?
And if the modules are not signed then they should be stripped.

- There are some pipelines (simple, uvc) that are not directly mapped to
an IPA.
- It is possible, and I think a likely use case, that for example the
IPU3 pipeline is selected, but a custom (then from another package) IPA
is used.
- libcamera provides extra separate options for pipelines and IPAs and I
assume someone has thought about that. Perhaps there will be more
possible pipeline and IPA combinations in the future.
For these reasons, I have decided to map these options completely and
not to include any further implications and relationships in the rule file.
Does that sound reasonable to you, or should I still change it as suggested?
Thanks,

Since commit 'ipa: raspberrypi: Use YamlParser to replace dependency on
boost' this shouldn't be necessary anymore, but maybe I missed something?

It is possible to build and use 'cam' without libdrm (as in my case),
but you get more features when additional libraries are available
(libdrm, libjpeg, SDL2).
Since at least one seems to need the KMS sink function, I can add an
extra option for "cam" that selects libdrm.
Would that meet your requirements?

Thanks for your input. I will also include the additional crypto options.
Is the reason for disabling module signing to reduce dependencies on the
target, or anything else?

Yes, it would reduce the dependencies if off. Also this gives the user
the ability to select the crypto lib which is already used on the
target. Since the worst case would be to pull a 2nd lib if one already
have one.
Don't know if there is some option to select a global crypto provider.
@Michael is this possible?

To leave the user the option to not enable it at all. Maybe your rootfs
size is very limited and you can't pull any of crpytolibs, then you can
turn it off.
> And if the modules are not signed then they should be stripped.
The IPAs running in a seperate process if they are not signed. So the
user has the choice between runtime overhead <-> rootfs size.

The architecture (and therefore the meson options) is designed in a way to
allow closed source IPAs. I don't think that this will be a very common use
case in PTXdist. So I prefer one option right now. We can always change
this later, if that assumption turns out to be wrong.

So, I like having a choice, because it allows minimizing the number of
crypto libraries. But these is not global default, because it's hard to
implement:
If it's just a default for a choice option, then it must be enabled before
all other packages: The default is is ignored if something is already
enabled. So changing the default has no effect either.
We could also hide the other options when a default is select. But that
means that there is no way to overwrite the default. And sometimes not all
backends have the same features.
Neither version is really desirable, so I never bothered to implement
anything like this.
