When a BSP uses vmlinux for boot, the kernel-image package is just
empty. But by default the kernel-vmlinux is not installed. Then the
pkg_postinst_kernel-image() would create a symlink to a non-existent
file. Fix this by adding the runtime dependency on kernel-vmlinux for
kernel-image if the KERNEL_IMAGETYPE is "vmlinux".

Rework the function so part it's internals can be re-used by fitImage
image type. The name of the temporary file , linux.bin , is recycled
a little more as it's now used for both the case where it is gzip
compressed and where it is not. This should be fine, since the file
is temporary and removed after the uImage was created anyway.
There is no functional change here.

Remove the lambda function setting KERNEL_IMAGETYPE_FOR_MAKE and instead
set it in the anonymous python function. This also allows us to handle
image types which are not supported directly by kernel, but require some
other kernel target to be built. This is the case for example with the
fitImage, which is the uImage successor.

The do_shared_workdir task does leave behind the necessary information in
shared-work after it completes. We don't make this a "full" sstate task
however since that means tarring up and copying what is usually a large
amount of data which would be better extracted straight from the original
SCM.
The issue with rm_work occurs since it removes the do_shared_workdir stamp
meaning subsequent builds will add it back if they need to touch any kernel
modules for example. This ends up triggering a near enough complete kernerl
rebuild since if configure reruns, populate_sysroot has to rerun.
This change promotes the task to have a "setscene" variant but it doesn't use
any of the sstate class lifting to generate the sstate file. The sstate function
will therefore never get called since the sstate object will never exist.
We can add the task to the list of tasks rm_work promotes to a setscene variant
and unwanted rebuilds of the kernel should be avoided.

Race condition between do_compile_kernelmodules and do_shared_workdir
tasks occurs when do_compile_kernelmodules changes files in
include/generated/* while do_shared_workdir tries to copy them to

Using populate_sysroot for this data was a nice idea but flawed as it
doesn't work in multilib builds. Instead we can use PKGDATA_DIR since
this is consistent over multilib builds. It also turns out to be
slightly neater code too. Hopefully this resolves the problem once and

With the rpm package backend enabled, running:
bitbake <image>
bitbake virtual/kernel -c clean
bitbake <image> -c rootfs -f
results in an image with incorrect kernel module dependency information.
The problem is that the System.map and kernel-abiversion files are needed
for depmod and after the recent kernel changes, these are no longer in
sstate.
Its reasonable to require the kernel to unpack/build if you're
about to build a module against it. It is not reasonable to require this
just to build a rootfs.
Therefore stash the needed files specifically for depmod.
Also fix some STAGING_KERNEL_DIR references which were incorrect, found
whilst sorting through his change.

commit 3b3f7e785e279 [kernel: Rearrange for 1.8] began the process of
moving the kernel source and build artefacts out of sstate control and
into a shared location.
This changed triggered some workflow issues, as well as bugs related
to the kernel source containing build output, and hence being dirty and
breaking kernel rebuilds.
To solve these issues, and to make it clear that the kernel is not under
sstate control, we move the source and build outputs to:
work-shared/MACHINE/kernel-source
work-shared/MACHINE/kernel-build-artifacts
Where kernel-build-artifacts is the kernel build output and
kernel-source is kept "pristine". The build-artifacts contain everything
that is required to build external modules against the kernel source,
and includes the defconfig, the kernel-abiversion, System.map files and
output from "make scripts".
External module builds should either pass O= on the command line, or
set KBUILD_OUTPUT to point to the build-artifacts. module-base.bbclass
takes care of setting KBUILD_OUTPUT, so most existing external module
recipes are transparently adapted to the new source/build layout.
recipes that depend on the kernel source must have a depedency on the
do_shared_workdir task:
do_configure[depends] += "virtual/kernel:do_shared_workdir"
With this dependency added, the STAGING_KERNEL_DIR will be populated and
available to the rest of the build.

After the recent kernel changes, non linux-yocto builds stopped working
properly for two reasons:
a) ${S} was being reset to ${WORKDIR}/git for example and STAGING_KERNEL_DIR
did not contain the source
b) Most builds were using ${B} == ${S}
This patch adds a fixup to the unpack function to handle the case where
${S} != ${STAGING_KERNEL_DIR} and also set up the infrastrcture so that
B != S for kernel builds from now on. The kernel build system is one of the
best for supporting this and there is no good reason not to take advantage
of it.

Currently unpack just forces sources over the current files. This change
ensures ${S} is cleaned out before sources are unpacked. This resolves
issues seen when upgrading to the new kernel class changes.
Ultimately, this should probably move to base.bbclass but one step at a
time, this solves an immediate problem blocking the other patches from
merging.

With the kernel build optimizations, we no longer copy the source from

In 1.8 we want to streamline the kernel build process. Basically we
currently have multiple copies of the kernel source floating around
and the copying/compression/decompression is painful.
Lets assume we have a kernel source per machine since in most cases
this is true (and we have a sysroot per machine anyway). Basically,
instead of extracting a source into WORKDIR, then copying to a sysroot,
we now set S to point straight at STAGING_DIR_KERNEL.
Anything using kernel source can then just point at it and use:
do_configure[depends] += "virtual/kernel:do_patch"
to depend on the kernel source being present. Note this is different
behaviour to DEPENDS += "virtual/kernel" which equates to
do_configure[depends] += "virtual/kernel:do_populate_sysroot".
Once we do this, we no longer need the copy operation in
do_populate_sysroot, in fact there is nothing to do there (yay).
The remaining part of the challenge is to kill off the horrible
do_install. This patch splits it off to a different class, the idea here
is to have a separate recipe which depends on the virtual/kernel:do_patch
and just installs and packages the source needed to build modules on
target into a specific package.
Right now this code is proof of concept. It builds kernels and kernel
modules. perf blows up in do_package with issues on finding the kernel
version which can probably be fixed by adding back the right bit of do_install,
and adding a dependency of do_package[depends] += "virtual/kernel:do_install"
to perf. The whole thing needs a good write up, the corner cases testing
and probably a good dose of cleanup to the remaining code.

This solves a regression introduced by OE-Core:9b75f6a (kernel:
use oldnoconfig before yes '' | make oldconfig).
The original oe_runmake explicitly calls 'die' command in case of
failure so the fallback code never runs. The fallback code needs
to handle the oe_runmake return code to call the backward
compatible callback so we introduced a new command called
oe_runmake_call which is used by oe_runmake.
This does not change the functional behaviour of oe_runmake so it
avoids any change except for the code which does need to handle
the oe_runmake exit code.

Removing files from the source tree via find, exec and rm is not the
most efficient operation, due to (among other things) the many forked
processes.
If we use -delete, it saves a significant amount of time. But -delete
does not work with -prune (since it forces -depth). To maintain the
lib, tools and scripts source files, we can hide them temporarily,
skip their hidden directories and then finally restore them.
Time for install before this change:
real 2m48.563s
user 0m35.220s
sys 0m33.036s
Time for install after this change:
real 1m21.301s
user 0m33.160s
sys 0m28.388s
We could further speed this up by using inline perl to delete the files,
but that complexity is avoided for now.

If a kernel is built without any external modules (aka no CONFIG_*=m),
then during a modules_install of the kernel an empty directory is
created at /lib/modules/${KERNEL_VERIONS}/kernel. This is behaviour of
the kernel infrastructure, the directory would normally be populated
with the modules that were built.
However because of the expectations of kernel-modules-split, no packages
are created when there are no modules and an empty directory lingers.
This raises QA issues as warning or errors (depending on the distro).
The following patch changes the kernel_do_install task to check if the
directory is empty and if so removes it.

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

on WORKDIR and its hard for different parts of WORKDIR to be on different
filesystems. Hardlinking instead of copying is therefore a nice performance
gain.
Also, completely skip the Documentation directory (adding a dummy Makefile
to keep make happy) and tweak the other cp commands to link since if we
don't we'd get "this is the same file" type errors from cp for some kernel
versions.
For do_install on linux-yocto, this takes it from 227s -> 84s.

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.

When building against the sysroot, out of tree modules can require modpost
and other utilities normally found in the kernel's scripts directory. For
the kernel source in the staging dir, these scripts have been removed to
avoid mixing archiectures when packaging kernel-dev (among other things).
Rather than further complicate the kernel's install rule, or its packaging,
we can restore the scripts by building them in the kernel staging directory
after the sstate is installed, making them available to packages that need them.
