kernel: Ensure an initramfs is added if configured

2019-03-22T21:40:46+00:00

If ${DEPLOY_DIR_IMAGE}/${INITRAMFS_IMAGE_NAME}.cpio does not exist,
nor any of the compressed variants, nothing is copied to kernel build's
./usr directory.

The code does not fail, but silently proceeds without a bundled initramfs.

Change to fail and tell the user something is wrong.

Also, if an initramfs is found, contrary to the comments, it does not stop
at the first uncompressed/compressed cpio image found. Instead it keeps
processing all so the last is used. Fix this to behave as per the comments.

kernel.bbclass: Fix incorrect deploying of fitimage.initramfs

2019-01-28T16:56:32+00:00

When kernel-fitimage and initramfs is enabled using
INITRAMFS_IMAGE_BUNDLE = "1", kernel do_deploy tries to deploy
fitImage.initramfs with following error

| install: cannot stat 'arch/arm64/boot/fitImage.initramfs': No such
file or directory

Skip deploying fitimage.initramfs, since fitimage does not
create fitimage.initramfs

kernel: don't assign the build user/host

2019-01-28T16:56:30+00:00

The KBUILD_BUILD_USER and KBUILD_BUILD_HOST variables were
assigned at the kernel class level, which made it impossible
to override them in the local configuration.

By setting only the default values of those variables in the
kernel class, it is now possible to override them as expected.

kernel: use olddefconfig as the primary target for KERNEL_CONFIG_COMMAND

2019-01-28T16:56:26+00:00

As was warned by commit 312ee68752fa [kconfig: announce removal of
oldnoconfig if used], oldnoconfig has been removed from the 4.20 kernel.

So we switch our default mode to olddefconfig.

commit fb16d8912 [kconfig: replace 'oldnoconfig' with 'olddefconfig',
and keep the old name as an alias] introduced olddefconfig in the 3.10
kernel, we shuffle oldnoconfig to the fallback target.

The fallback mode allows kernels between 3.10 and the currently listed
oldest kernel of 3.2 to continue to configure.

kernel.bbclass: allow custom KERNEL_IMAGEDEST

2018-10-25T13:36:34+00:00

Some distros want to install the kernel in a custom location other
than /boot and have it properly packaged, so it's useful to use a
weaker assignment.

kernel.bbclass: Avoid iterating over KERNEL_IMAGETYPES twice

2018-09-22T18:22:30+00:00

During deploy we iterate over KERNEL_IMAGETYPES twice, with no consumer
of our changes in the interim. Collapse these two loops into one.

kernel: Fix modules tarball generation with usrmerge

2018-09-22T18:22:30+00:00

When usrmerge is enabled the kernel modules aren't under /lib, but /usr/lib;
ensure we fetch the modules from the correct location so we don't have a
tarball which consists of a single symlink.

Revert "kernel.bbclass: do not deploy fitImage; kernel-fitimage.bbclass does that."

2018-09-22T18:22:30+00:00

This reverts commit 65cded55fa96b1ba72149a31689c081ac27af7f7.

The fitImage deployed here is the one generated in kernel-fitimage.bbclass,
whereas the one deployed by kernel-fitimage.bbclass is a raw image, so we
need the one deployed here keeping.

kernel.bbclass: do not deploy fitImage; kernel-fitimage.bbclass does that.

2018-09-12T07:17:27+00:00

kernel-fitimage.bbclass replaces an occurance of "fitImage" in
KERNEL_IMAGETYPE_FOR_MAKE by an image type that is buildable for the
architecture (such as zImage). The kernel-fitimage.bbclass packs that
image as sub-image in a flattened image tree image (fitImage) and
deploys this fitImage along with the image tree source file (.its).

kernel-fitimage.bbclass does not alter KERNEL_IMAGETYPES, which thus
also contains "fitImage", which kernel.bbclass will also deploy
redundantly with different naming.

The result is a dual deployment with slightly different naming,
each with a set of symlinks.

The solution chosen is to have fitImage deployment be handled by
kernel-fitimage.bbclass, and have kernel.bbclass ignore fitImage
types during deployment.
