The Linux kernel image is typically found in arch/ARCH/boot/, which is
why LINUX_IMAGE_PATH is defined as:
LINUX_IMAGE_PATH = $(LINUX_ARCH_PATH)/boot/$(LINUX_IMAGE_NAME)
However, on MIPS, some kernel image types are available from
arch/mips/boot/compressed, or even at the top-level directory. For
such cases, LINUX_IMAGE_NAME might be set (using
BR2_LINUX_KERNEL_IMAGE_NAME) to values such as:
compressed/vmlinux.bin.z
or
../../../uzImage.bin
Except that the line:
$(INSTALL) -m 0644 -D $(LINUX_IMAGE_PATH) $(1)/$(LINUX_IMAGE_NAME)
will lead to such images be installed in:
$(TARGET_DIR)/boot/compressed/vmlinux.bin.z
$(BINARIES_DIR)/compressed/vmlinux.bin.z
and:
$(TARGET_DIR)/boot/../../../uzImage.bin
$(BINARIES_DIR)/../../../uzImage.bin
which of course is completely bogus.
So let's install them under their name, not their full relative path
to arch/ARCH/boot/.

When a package installs a kernel module, it is currently not possible to
have it loaded with modprobe or when the kernel requests an alias for
it, as the module is not listed in /lib/modules/<kernel-version>/modules.dep
and the associated files.
So, we need to run depmod after all packages are installed, to register
any such out-of-tree module.
This means we should be able to let go of calling depmod at the time the
kernel is installed, but if we pass an invalid command, the kernel
whines:
DEPMOD 5.4.27
./scripts/depmod.sh: 46: /dev/null: Permission denied
make[2]: *** [Makefile:1326: _modinst_post] Error 126
This is because the kernel does not directly call to depmod, but uses a
wrapper that is not happy if depmod is not depmod.
Since the call to depmod does not cost much, we just keep it.

While the kernel is built for the target, the build may need various host
libraries depending on config (and kernel version), so use HOST_MAKE_ENV
instead of TARGET_MAKE_ENV.
In particular, this ensures that our host-pkgconf will look for host
libraries and not target ones.
Fixes building scripts/dtc for Buildroot configurations enabling libyaml and
host-pkgconf for kernels after commit 067c650c45 (dtc: Use pkg-config to
locate libyaml).
With this enabled, we can drop the PKG_CONFIG_* variables for the

When 'make' includes a new Makefile, it appends its path to the MAKEFILE_LIST
variable. From that variable, we construct a few set of derivative
variables:
pkgdir = $(dir $(lastword $(MAKEFILE_LIST)))
pkgname = $(lastword $(subst /, ,$(pkgdir)))
Essentially, pkgdir is the full directory where the package is located
(either relative to Buildroot's top directory for in-tree packages, or
absolute for packages in br2-external trees), while pkgname is the last
component of that directory.
pkgdir is in turn used to seed FOO_PKGDIR.
This all happens when we eventually call the package-generic infra,
later down in the file.
When they are parsed, the Makefiles for each linux-extensions are
appended to MAKEFILE_LIST, after the linux.mk one. But since they are
located in the same directory as the main linux.mk, the last component
of MAKEFILE_LIST, which is no longer the main linux.mk, will still yield
the correct values for the linux package.
This is a tough assumption we made there and then.
When we added the support for br2-external linux extensions, we where
very cautious to explicitly scan them from a directory named 'linux', so
that this would yield the correct package name.
And that worked well so far, until someone needed to build an older
kernel, for which our conditional patch is needed, and which just
failed:
/bin/bash: [...]/buildroot-external-linux-test/linux//0001-timeconst.pl-Eliminate-Perl-warning.patch.conditional: No such file or directory
When we scan linux extensions from a br2-external tree, the last
component of MAKEFILE_LIST is no longer in the same directory as the
main linux.mk, and thus the assumption above falls to pieces...
Again, when we added support for linux extensions from br2-external,
although we cared about the package name (pkgname), we completely missed
out on the package directory, and the LINUX_PKGDIR variable.
We do not have a very clean way out of this mess, but we have a nice
dirty trick: Scan the linux extensions from a br2-external tree before we
scan the in-tree ones. That way, the last component of MAKEFILE_LIST is
back to one that is in the same directory as the main linux.mk, and
we're back on tracks.
This is still very fragile, though, but short of a complete overhaul on
how packages are parsed and evaluated, this is the best we can come in
short order.

ARC processors have configurable size of MMU page. This configuration
happens during ASIC design and couldn't be changed in final silicone
not to mention runtime changes.
Given PAGE_SIZE macro is used a lot throughout the Linux kernel sources
we just hardcode a required value during the kernel configuration.
We used to support different MMU page sizes for ARC in Buildroot for
quite some time now but so far we only tweaked uClibc on the matter.
That left us with the kernel configured with whatever was in used defconfig.
In most of real cases that's OK because typically we're building firmware
for a particular ASIC which is supposed to have a unique kernel defconfig.
But if we're dealing with FPGA-based boards or even simlators like
Synopsys DesignWare nSIM or QEMU it's possible to have dfferent MMU page
size configured in that target mostly for the sake of testing.
And so we're trying to solve 2 problems here:
1. Make sure both user-space (via libc settings) and the Linux kernel
are "on the same page", i.e. expect to use the same MMU page size.
2. Simplify process of testing different page sizes.
As now we first need to set page size in Buildroot and then in the
kernel via "make linux-configure" or via Kconfig fragment.

Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option is only
available to be selected by another config option. This option controls
if the Linux build system should build the DTB itself, or if buildroot
explicitly calls the Linux Makefile like "make something.dtb".
My use case: I want to build an OpenRISC image with a custom device tree
file. OpenRISC does not support appended DTBs, and I'm not using a
bootloader, but link everything into a single kernel (vmlinux) image.
The kernel option CONFIG_OPENRISC_BUILTIN_DTB allows me to specify a dtb
file, which is typically located in the kernel source tree in
arch/openrisc/boot/dts/NAME.dts.
Since my dts file is not part of the upstream kernel, I have two
options: either patch the kernel to include the DTS file, and then
specify it using the CONFIG_OPENRISC_BUILTIN_DTB option.
Or use buildroot's BR2_LINUX_KERNEL_CUSTOM_DTS_PATH config option to
copy any DTS file to the kernel source tree, and then specify this file
with CONFIG_OPENRISC_BUILTIN_DTB as before.
However, the second option also requries the buildroot option
BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT to be set, otherwise I end up with a
"make -C kerneldir NAME.dts" call, which doesn't work (no such target
exists).
Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option exists, but it's
not visible/available. Simply making it available solves the problem for
me nicely.

>From patch [1] included in kernel >= 5.0:
"The upcoming GCC 9 release extends the -Wmissing-attributes warnings
(enabled by -Wall) to C and aliases: it warns when particular function
attributes are missing in the aliases but not in their target.
In particular, it triggers for all the init/cleanup_module
aliases in the kernel (defined by the module_init/exit macros),
ending up being very noisy.
These aliases point to the __init/__exit functions of a module,
which are defined as __cold (among other attributes). However,
the aliases themselves do not have the __cold attribute.
Since the compiler behaves differently when compiling a __cold
function as well as when compiling paths leading to calls
to __cold functions, the warning is trying to point out
the possibly-forgotten attribute in the alias."
Werror is set by default while building ppc kernel [2], but
some warning can be introduced while building current kernel with
newer compiler (for example building kernel 4.19 with gcc 9.1).
For the same reason why we remove Werror in packages's compiler
flags. Building with Werror is not bulletproof when we start
using a newer compiler that introduce new warnings.
This is the case here.
Also this option is a bit strange since it's specific to ppc kernels:
"The intention is to make it harder for people to inadvertantly
introduce warnings in the arch/powerpc code."
Other kernel developers on other arch may be interested by a
similar/more generic option.
So, It's clearly intended for kernel developers.
Instead of backporting this patch [1] to kernel 4.19, select
unconditionally the Kconfig option CONFIG_PPC_DISABLE_WERROR
that allow to disable Werror.

We currently do the Linux build as follows:
make <imagename>
if modules enabled; make modules; fi
However, Clement Léger recently reported that due to us not using the
"all" target, the GDB scripts that the kernel can build when
CONFIG_GDB_SCRIPTS is enabled are not built, since upstream kernel
commit 67274c083438340ad16c1437caebc84e1253b224 (merged in v5.1) moved
that logic to a separate scripts_gdb target, which is a dependency of
the "all" target.
While we could add some more logic to explicit generate the
"scripts_gdb" target, this logic would fail on Linux < 5.1 for which
this make target doesn't exist.
So instead, let's simplify the build logic, and use:
make all <imagename>
The "all" target automatically depends on "modules" if CONFIG_MODULES
is set, so we no longer need to explicit generate the "modules" target
separately.
As a result of this change, we may generate additional kernel images
compared to what was done previously, but such images would anyway not
be installed, and the additional build time is minimal.
We did some research as to why the kernel build was done like this in
Buildroot, and it's been like that since linux/linux.mk was added back
in 2010 by commit 487e21cff6 ("New,
simpler, infrastructure for building the Linux kernel").

Xenomai has two mutually exclusive cores:
- Cobalt: dual-kernel approach: patched kernel + userland
- Mercury: only userland
In the Cobalt core, not all architectures are supported. This is the source
of the existing ARCH_SUPPORTS variable.
In the Mercury core, there is no imposed architecture restriction.
Rename the XENOMAI_ARCH_SUPPORTS flag to XENOMAI_COBALT_ARCH_SUPPORTS and
move its check from the Xenomai package to the Cobalt core.
Nevertheless, even for Mercury, there are some restrictions:
- pthread_atfork is used, which requires an MMU
- sync functions like __sync_sub_and_fetch and __sync_add_and_fetch are
expected.
As the corresponding 'linux extension' selects Xenomai, we add the
MMU and sync dependencies there too. They may or may not already be covered

However, for consistency with other kconfig-package packages, we chose

When using an initramfs, on the first-pass build, we create a dummy cpio
so that the build succeeeds. The real cpio will come later, and we'll do
a second-pass build to use the actual cpio.
However, when we touch that dummy cpio, the images/ directory may not
yet exist, since commit d0f4f95e39 (Makefile: rework main directory
creation logic) removed its creation at the begining of the build, to
only at the moment we need it, i.e. during the *_INSTALL_IMAGES_CMDS
steps.
However, the linux build is not a _INSTALL_IMAGES_CMDS step, so there is
no guarantee that images/ already exist at that time.
Fix that by explicitly creating images/ before touching the dummy cpio.

Checking for the existence of the dtc binary built by the
non-dependent dtc package may cause instable behaviour when giving more
freedom on the order of how the packages are built (parallelization).
In addidion, when moving to per-package host/target method, the check
would always trigger in the isolated host, leading to linux-dtc always
being installed as dtc.
This in turn may lead to undesired overwriting of the real host-dtc binary
when finally assembling the global host dir.
Thus rework the linux-dtc install condition to be defined by configuration
rather than compile time order.

The commit that added the dependency on host-{bison,flex} did
so because the pre-generated kconfig parser source files were
removed from the kernel tree, in linux-4.16.
But then, in linux-4.17, the pre-generated dtc parser source
files were in turn removed as well.
So, document the two reasons why they are needed, so we don't
accidentally remove them when we (soon) introduce the kconfig
dependencies.

Commit f13477b (linux: config.in: add comment for Arm Cortex-M) added a
comment so that the user that the linux kernel may miscompile with
binutils 2.29+, when the target is an armv7m CPU.
However, the real trigger is a compilation in thumb2 mode, which happens
to be the only option for armv7m CPUs.
We can't know whether the kernel will be built in arm or thumb2 mode,
though, because we do not have that information: it is only available in
the Linux' .config file, which we don;t have access to at the time we
run our menuconfig.
So, relax the conditions under which the comment is made, so that it
appears as soon as binutils are >= 2.29 (i.e. not 2.28, which is the
oldest we support) for ARM CPUs.

Kconfig uses either pkg-config or hard-coded /usr/include paths to find
the ncurses or ncursesw library. If ncursesw is found, it will include
<ncursesw.h>. Since Buildroot's host-ncurses doesn't install a .pc file,
and linux.mk anyway doesn't pass the pkg-config options to find the host
pkg-config files, Kconfig will always find the system's ncursesw.h.
However, since commit dde090c299 (linux: fix passing of host CFLAGS and
LDFLAGS) HOST_LDFLAGS is passed to the linux build system. Thus, if
host-ncurses was already built before 'make linux-menuconfig' is called,
the build will pick up libncurses from the host directory, which is NOT
widechar. Thus, two different ncurses configurations are mixed into the
final mconf program. This will result in serious breakage in the
rendering of the menus (lots of @ and question mark characters).
As a workaround (suggested by Yann), don't pass HOST_CFLAGS and
HOST_LDFLAGS when running kconfig commands. For kconfig, we should never
need host packages anyway. This way, the kconfig calls will always use
the system's ncurses and never our host-ncurses.
Note that the same problem could pop up for other kconfig packages as
well if we ever pass HOST_CFLAGS/HOST_LDFLAGS to them. We could force
HOSTCC=$(HOSTCC) directly in kconfig-package. However, for now there
are no other packages that exhibit this problem, so this can be
revisited when they do.

We were passing HOSTCFLAGS="$(HOSTCFLAGS)" to Linux. However:
- HOSTCFLAGS in Buildroot doesn't exist, and is empty, so this
assignment never did anything. The name of the variable in
Buildroot in HOST_CFLAGS.
- HOSTCFLAGS in Linux isn't used everywhere, and passing it overrides
the default HOSTCFLAGS value defined in the main Linux kernel
Makefile.
In addition, there is no way to pass additional host LDFLAGS in the
Linux kernel build system.
Therefore, we simply shoehorn our HOST_CFLAGS and HOST_LDFLAGS while
passing HOSTCC to the Linux kernel build system. This has been tested
to work fine with host OpenSSL and host libelf only available in

Currently, the rule to rebuild the Linux kernel with an initramfs
directly depends on the path of the file of the intermediate cpio image.
This is inherently "bad" from a purity point of view; linux.mk should
not have to delve into the fs internals.
Rather, make it directly depend on the "frontal" rule that generates the
cpio image.
Drop the comment for linux-rebuild-with-initramfs, it was misleading
(talking about generating "the initramfs list of files", which is not
what was done, since we use a cpio as source of initramfs, not a list of
files).
