[meta-raspberrypi] core-image-minimal for raspberrypi3-64 manifest/sdimg contains no kernel modules

[meta-raspberrypi] core-image-minimal for raspberrypi3-64 manifest/sdimg contains no kernel modules

[Steve Pavao]

There seems to be a problem with the core-image-minimal bitbake for raspberrypi3-64 target at head of sumo in all repos.  I wonder if it’s also a problem for the raspberrypi3 target.

No kernel modules appear in the .manifest, and no kernel modules are put into the sdimg.  It’s hard to believe it’s true, but that’s what I'm seeing.

The problem does NOT occur for the rpi-hwup-image bitbake, which is actually deprecated in poky 2.5/sumo.

Before you retire the rpi-hwup-image bitbake target, will you please make sure that the kernel modules from the core-image-minimal build make it into the .manifest and therefore into the sdimg?

Please let me know where to log this issue, so I can send you the .manifest diffs, some ls command output showing the large size difference between the core-image-minimal and rpi-hwup-image sdimg files for identical builds, and perhaps some file listings to show that one of the builds contains kernel modules (rpi-hwup-image) and the other does not (core-image-minimal).

please build core-image-base and see if that helps

Khem - that does help.  It also provides some other packages that aren’t in the deprecated rpi-hwup-image, but that doesn’t seem to hurt.

Max - thanks for the explanation about adding that package to the image as a possible solution.  In this case, I’m trying to avoid multiple manual steps and just use a single bitbake target to acheive the build I need, though.

Andre - I have since read about core-image-minimal since receiving the warning message that "rpi-hwup-image is deprecated - use core-image-minimal instead” and having problems due to the missing modules.  You are technically correct.   I would like to state my opinion though that to unconditionally warn the user to use core-image-minimal instead of rpi-hwup-image  (which definitely packages kernel modules if they are there) is not often the best advice to give.

Thanks to you all for the useful replies.

This should be fixed in meta-raspberrypi, care to submit a patch
to use core-image-base instead ?

Sure, I’ll submit a patch.  Should it unconditionally recommend core-image-base, or should it still recommend core-image-minimal if the kernel modules list is empty? (Could that condition possibly happen if the user cleared it in local.conf?)

fact that we added modules to original image. its better to recommend
core-image-base

Note that the 'kernel-modules' package is one of the packages built by a kernel recipe.
It is a meta package which RDEPENDS on all kernel module packages built by your kernel
configuration. So adding that package to your image should do the trick.

To understand what's happening it's worth also reading the SUMMARY for
core-image-minimal:

  SUMMARY = "A small image just capable of allowing a device to boot"

and comparing to core-image-base:

  SUMMARY = "A console-only image that fully supports the target
device hardware"

ie the fact that core-image-minimal doesn't contain any kernel modules
is a feature, not a bug.
