Paul Eggleton 337de046c8 classes/kernel: move module postinst commands to kernel-base
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].

Mike Crowe 97af6e46da kernel.bbclass: Stop bundle_initramfs thwarting sstate cache and fix race
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.)

Xufeng Zhang 5411bbcdb5 kernel.bbclass: Delay rm_work to run after do_bundle_initramfs
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.

Jason Wessel 072c4e123f kernel.bbclass: Allow INITRAMFS_TASK to trigger copy initramfs code
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.

Jason Wessel 0fa12e4466 kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency and bundling
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.

Mike Crowe 600f4e38ad kernel.bbclass: Add dependency on binutils
Compiling the Linux kernel requires binutils; kernel.bbclass uses
INHIBIT_DEFAULT_DEPS so it had better depend on binutils explicitly.

(The lack of this dependency isn't always a problem because binutils
is required to build gcc-cross but if gcc-cross is reconstructed from
the sstate cache then gcc-cross's dependency on binutils-cross is
ignored due to being in the safe dependency list in
setscene_depvalid.)

Michel Thebeau cd2f003b51 kernel.bbclass: do_strip: allow recipes to strip the kernel
Allow recipes to specify sections to be stripped from the kernel output
using KERNEL_IMAGE_STRIP_EXTRA_SECTIONS.  For example:

KERNEL_IMAGE_STRIP_EXTRA_SECTIONS = ".comment .unwanted"

The kernel output is stripped in place.

Since the toolchain does not give indication when the specified sections
are absent, we read the sections first and make this report by issuing a
warning to the developer.

The toolchain by default strips the image with the -s option (even
when -s is not specified):
-s --strip-all       Remove all symbol and relocation information

For example, these sections are always removed:
.debug_aranges
.debug_info
.debug_abbrev
.debug_line
.debug_frame
.debug_str
.debug_loc
.debug_ranges
.symtab
.strtab

In addition to these, the sections listed in
KERNEL_IMAGE_STRIP_EXTRA_SECTIONS will also be removed.

Only stripping of vmlinux (elf) is supported at this time.  A warning
will be given if the image type is not vmlinux.

Stripping the image could also be done in the kernel, but that would
only work for linux-yocto based kernels, so it's not the route we
decided to go.

Michel Thebeau e57284abca kernel.bbclass: do_sizecheck: update path to build image and do not delete
do_sizecheck has a few issues especially with vmlinux image type.

It breaks because KERNEL_OUTPUT is a path relative to ${B}.  When
do_sizecheck runs it does not find the file (because the working
directory is elsewhere) and does not fail.

Also, the image file referenced by KERNEL_OUTPUT may be a link.

Finally, when do_sizecheck deletes the oversized kernel image it leaves
the previously run do_compile task with inaccurate status.

So, do the following:
 - specify that the working directory should be ${B}
 - use ls -L to reference to the real file, and ensure that the link
   file is created
 - keep the oversized image file so the status of do_compile is valid

Chase Maupin 188a52171d kernel bbclass: return to original directory in do_deploy
* During the base kernel_do_deploy function the directory is
  changed to DEPLOYDIR in order to do some cleanup and symlinking.
  However, the directory is not changed back to the original
  starting directory ${S} at the end.  For append functions this
  means that the starting directory is not ${S} as expected but
  instead ${DEPLOYDIR}.

  For functions like the do_deploy_append in
  recipes-kernel/linux/linux-dtb.inc there is an assumption that
  you are still in the source directory and not the DEPLOYDIR.
  Without this change the .dtb files are not copied because the
  check for the existence of ${DTS_FILE} which is a relative
  path from the ${S} directory fails.  This means that the .dtb
  files are not copied into the deploy directory and subsequently
  the deploy/images directory.

  In the log.do_deploy file you will see lines like:

    Warning: arch/arm/boot/dts/xxxxx.dts is not available!

We cannot pass this information in EXTRA_OEMAKE, as
"meta/classes/kernel.bbclass" explicitly ignores all EXTRA_OEMAKE
settings.  So add KERNEL_EXTRA_ARGS parameter so affected boards
can add for example

	KERNEL_EXTRA_ARGS = "LOADADDR=0x80008000"

to their configuration.  We make this general enough so other needed
command line options can be passed as well when compiling the kernel.

Mark Asselstine dbfa6f9563 kernel: avoid copying unnecessary files during do_install
kernel_do_install() populates $kerneldir with files needed to build
external modules. To accomplish this there are several copy commands
to get source from the kernel source tree and build trees after which
a 'clean' is performed. Since we are copying from the build tree we
get about 1G of .o and .cmd files copied over only to have them
removed when we clean. This adds additional IO overhead as well as
overhead caused by pseudo. By avoiding copying these files in the
first place we get multiple gains:
  * avoid initial copy
  * avoid file deletes during clean
  * reduce pseudo overhead

Additionally we are making use of cpio vs cp which tends to be
significantly faster at performing copies.

With these changes I observe a 15-30% decrease in the time to complete
the do_install() operation on the kernel.

we want to pass -march and -mtune options as CFLAGS to kernel
build so that compiler picks the right subarch flags when
compiling assembly files in particular. Otherwise defaults
are chosen which may not be right in many case e.g. when
compiling kernel for collie machine we should use arch=armv4
but it uses toolchain/as defaults which is armv5te

in some case e.g. thumb1 we know that kernel can not be compiled

Bruce Ashfield 4211de44e0 kernel.bbclass: remove explicit version.h target
The compilation routine for the kernel has an explicit call to
build version.h, which works fine for most kernels, but the
location of it has recently changes.

commit d183e6f5 [UAPI: Move linux/version.h]
commit 10b63956 [UAPI: Plumb the UAPI Kbuilds into the user
                 header installation and checking]

moves the file to include/generated/linux/version.h and then to
include/generated/uapi/linux/version.h.

As a result kernel builds of 3.7 or bisection builds of intermediate
kernel commits will fail with:

  make[2]: *** No rule to make target `include/linux/version.h'.  Stop.

Making the explicit version.h build conditional on the version, or
via a file test would fix the problem, but it introduces some complexity
to the build.

Even without an explicit call to build version.h, it is always produced
by the kernel build, so it can simply be removed.

This extra make line was originally so that the kernel version could be
determined, so that then different instructions could be executed depending
on whether it was a 2.4 or 2.6 kernel. Since we no longer support 2.4, this
code is no longer needed.

Phil Blundell 8f85691860 kernel.bbclass, module.bbclass: Make update-modules optional
The update-modules mechanism is something of a historical relic and it isn't
entirely clear that it has a great deal of value nowadays.  Also, it causes a
problem when building a read-only rootfs since update-modules itself refuses
to configure offline.

Allow DISTROs to circumvent this whole thing by declaring (via DISTRO_FEATURES)
that they don't wish to use update-modules.  This is backfilled for existing
distributions and will have to be marked as CONSIDERED by those who actually
don't want it.

Richard Purdie 5fdbda6922 classes: Update to use corrected bb.utils.explode_dep_versions2 API
The bb.utils.explode_dep_versions function has issues where dependency information
can be lost. The API doesn't support maintaining the correct information so this
changes to use a new function which correctly handles the data.

This patch also fixes various points in the code to ensure that we do not have any
duplicates in things that use explode_dep_versions.

A new sanity test to test the contents of the R* variables is also added.

Liang Li 9a1705ef80 kernel.bbclass: fix INC directory for SLANG
In the kernel's tools/perf/Makefile CFLAGS was previously hard coded to
contain "-I/usr/include/slang" to work with hosts that have
"/usr/include/slang/slang.h" as well as hosts that have
"/usr/include/slang.h". This path can cause compile warnings like:

  cc1: warning: '/usr/include/slang' doesn't exists.

  or

  cc1: warning: include location "/usr/include/slang" is unsafe for
  cross-compilation [-Wpoison-system-directories]

Then in some cases warnings become errors if WERROR is enabled hence
build errors.

In coordination with a kernel fix, we can fix this error for all
kernels by modifying the perf Makefile within the staged kernel
source.

asm/unistd.h includes asm/unistd_64.h on x86_64
and asm/unistd_32.h on i386 but these files are
generated files in 3.4 and when we do 'make clean' they get
deleted and it shows up as an error when building
external modules. May be its a 3.4 kernel bug may be not
but make clean should have left the tree in
a shape to build modules but it does not.

Probably we should run make modules_prepare after having
run make clean.

The intent of the uImage code in this class includes the following

1) be able to specify custom load addresses without needing to patch the kernel
2) add better information to the uImage description field

The current state is a NOP anyway, the kernel will always build a uImage when you tell it to 'make uImage'.

weakly Set KEEPUIMAGE to 'yes' in default-distrovars.inc which preserve the
current OE-Core behavior. Machines which are being ported from oe.dev and need to
regenerate uImage can set this to be empty
