classes/kernel: move module postinst commands to kernel-base

2014-04-11T11:02:01+00:00

Since kernel-base is the package that contains the files that depmod
needs to run, we should be running depmod from the kernel-base
postinstall rather than kernel-image.

Fixes [YOCTO #5392].

kernel.bbclass: Stop bundle_initramfs thwarting sstate cache and fix race

2014-01-24T12:47:58+00:00

The new do_bundle_initramfs task introduced in
609d5a9ab9e58bb1c2bcc2145399fbc8b701b85a defeats using the sstate
cache. The kernel is resurrected from the sstate cache but ends up being
built again since do_bundle_initramfs depends on do_compile.

The task is no longer nostamp to avoid causing unnecessary rebuilds. The
sstate checksum stamps should know when to rebuild.

The task now runs before do_deploy and part of the work has been moved to
do_deploy where it now writes to ${DEPLOYDIR} rather than
${DEPLOY_DIR_IMAGE} so that the files end up in sstate.

The task can also race against do_install since both call into the kernel
build system. This is fixed by making do_bundle_initramfs run after
do_install (which therefore also fixes the problem that
3baa63b4d588c3262254528b406ede265dd117bf was addressing.)

Revert "kernel.bbclass: move bundle_initramfs after kernel_link_vmlinux"

This reverts commit 3baa63b4d588c3262254528b406ede265dd117bf. It broke
builds that aren't using kernel-yocto.

kernel.bbclass: move bundle_initramfs after kernel_link_vmlinux

2013-12-12T16:53:10+00:00

${KERNEL_OUTPUT} is being renamed/restored in bundle_initramfs task, so we
must ensure bundle_initramfs run after kernel_link_vmlinux where the link
of vmlinux is created as the bootable image.

kernel.bbclass: Delay rm_work to run after do_bundle_initramfs

2013-12-12T16:53:06+00:00

Since kernel will build twice when we are trying to bundle kernel
and initramfs together after commit 609d5a9ab("kernel.bbclass,
image.bbclass: Implement kernel INITRAMFS dependency and bundling"),
thus, the second building for kernel would fail if rm_work is done
previously.

To fix this problem, we need to make do_bundle_initramfs task run
before do_rm_work task.

kernel.bbclass: unset LDFLAGS when run devshell in kernel recipe

2013-10-14T15:54:26+00:00

When user runs devshell in kernel recipe and compiles kernel,
this will fail by unrecognized option of LD.

----
$ make
...
arm-poky-linux-gnueabi-ld: unrecognized option '-Wl,-O1'
arm-poky-linux-gnueabi-ld: use the --help option for usage information

This set to empty LDFLAGS when user runs the devshell, and solve this problem.

kernel.bbclass: Allow INITRAMFS_TASK to trigger copy initramfs code

2013-09-30T21:02:26+00:00

Activating the INITRAMFS_TASK can cause circular dependencies, but
that is up to the end user to resolve in recipes.  The INITRAMFS_TASK
should also trigger immediate linking of the cpio task in the first
compile pass.  This was a subtle regression introduced by: 609d5a9ab
(kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency
and bundling).

This patch restores the previous behavior and only affects the
INITRAMFS_TASK which is not set by any of the default build profiles
in oe-core.

kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency and bundling

2013-09-06T22:01:50+00:00

This patch aims to fix the following two cases for the INITRAMFS generation.
  1) Allow an image recipe to specify a paired INITRAMFS recipe such
     as core-image-minimal-initramfs.  This allows building a base
     image which always generates the needed initramfs image in one step
  2) Allow building a single binary which contains a kernel and
     the initramfs.

A key requirement of the initramfs is to be able to add kernel
modules.  The current implementation of the INITRAMFS_IMAGE variable
has a circular dependency when using kernel modules in the initramfs
image.bb file that is caused by kernel.bbclass trying to build the
initramfs before the kernel's do_install rule.

The solution for this problem is to have the kernel's
do_bundle_initramfs_image task depend on the do_rootfs from the
INITRAMFS_IMAGE and not some intermediate point.  The image.bbclass
will also sets up dependencies to make the initramfs creation task run
last.

The code to bundle the kernel and initramfs together has been added.
At a high level, all it is doing is invoking a second compilation of
the kernel but changing the value of CONFIG_INITRAMFS_SOURCE to point
to the generated initramfs from the image recipe.

kernel.bbclass: Correct post(inst|rm) package association

2013-08-13T17:13:19+00:00

Fixes [YOCTO #4991]

The kernel image is installed as part of the kernel-image package, but
the symlink creation/removal via alternatives is being done in
pkg_post(inst|rm)_kernel-base.

Move the postinst alternatives logic into the kernel-image functions.
