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
by XENOMAI_COBALT_ARCH_SUPPORTS flag.

linux is a bit different than other kconfig-package, because it has
"toolchain" in KCONFIG_DEPENDENCIES. Thanks to this, host-ccache *is*
ready by the time kconfig invocations are made, so we could use
$(HOSTCC) as the host compiler for kconfig related operations.
However, for consistency with other kconfig-package packages, we chose
to use $(HOSTCC_NOCCACHE) as well.
We cannot rely on the default value of HOSTCC passed by the
kconfig-package infrastructure, because $(LINUX_MAKE_FLAGS) also
contains a HOSTCC definition that would override the one passed by the
kconfig-package infrastructure.

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

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

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.

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

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

We don't have a hash for any linux version. We currently also don't
have a hash for the latest version, but if we ever add a hash, it
will only be for the latest version.
This simplifies the code a little because soon we will add hash checks
for git as well, so we also need an exclusion in that case. It's much
easier to always exclude except in the single case where we do have a
hash.

However, there was a typo for one of the variables: CONFIG_TMPFS_XATTR
was written as CONFIG_TMPFS_POSIX_XATTR, which does not exist (and never
ever existed, at least not since 2.6.12)...

A long time ago, the blind config option BR2_LINUX_KERNEL_UBOOT_IMAGE
was introduced to be able to trigger the linux -> host-uboot-tools
dependency. Back in those days, there was no user-configurable
BR2_PACKAGE_HOST_UBOOT_TOOLS.
Now, however, it is possible to select a custom kernel image name that
needs uboot-tools, and manually enable BR2_PACKAGE_HOST_UBOOT_TOOLS. In
this case, however, the linux -> host-uboot-tools is missed and the
build is not reproducible. An example of such a situation is the
upcoming CI40 defconfig.
As a solution, remove BR2_LINUX_KERNEL_UBOOT_IMAGE entirely. Instead,
just select BR2_PACKAGE_HOST_UBOOT_TOOLS and add the dependency if it
is selected.
Note that this may introduce a redundant dependency in case the user
selected BR2_PACKAGE_HOST_UBOOT_TOOLS for some other reason (e.g. to
be able to generate a U-Boot environment to include in the image, while
the kernel is built as a zImage). However, the redundant dependency
shouldn't hurt much.

Fix kernel reproducible build if a non-C locale is used on the host
system.
When building the Linux kernel, scripts/gen_initramfs_list.sh does 'date
-d"$KBUILD_BUILD_TIMESTAMP" +%s'. In linux.mk, Buildroot sets
KBUILD_BUILD_TIMESTAMP to "$(shell date -d @$(SOURCE_DATE_EPOCH))".
For example, if LANG=fr_FR.UTF-8 is defined in the host system, it does
not work:
- LC_ALL=C date -d"$(LC_ALL=C date)" : ok
- LC_ALL=C date -d"$(LC_ALL=fr_FR.UTF-8 date)" : error
LANG/LC_ALL variables exported in the main Makefiles are not passed in
the $(shell ...) sub-shells.

The kernel source tree also contains the sources for various userland
tools, of which cpupower, perf or selftests.
Currently, we have support for building those tools as part of the
kernel build procedure. This looked the correct thing to do so far,
because, well, they *are* part of the kernel source tree and some
really have to be the same version as the kernel that will run.
However, this is causing quite a non-trivial-to-break circular
dependency in some configurations. For example, this defconfig fails to
build (similar to the one reported by Paul):
BR2_arm=y
BR2_cortex_a7=y
BR2_ARM_FPU_NEON_VFPV4=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_INIT_SYSTEMD=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_CUSTOM_GIT=y
BR2_LINUX_KERNEL_CUSTOM_REPO_URL="https://github.com/raspberrypi/linux.git"
BR2_LINUX_KERNEL_CUSTOM_REPO_VERSION="26f3b72a9c049be10e6af196252283e1f6ab9d1f"
BR2_LINUX_KERNEL_DEFCONFIG="bcm2709"
BR2_PACKAGE_LINUX_TOOLS_CPUPOWER=y
BR2_PACKAGE_CRYPTODEV=y
BR2_PACKAGE_OPENSSL=y
BR2_PACKAGE_LIBCURL=y
This causes a circular dependency, as explained by Thomas:
- When libcurl is enabled, systemd depends on it
- When OpenSSL is enabled, obviously, will use it for SSL support
- When cryptodev-linux is enabled, OpenSSL will depend on it to use
crypto accelerators supported in the kernel via cryptodev-linux.
- cryptodev-linux being a kernel module, it depends on linux
- linux by itself (the kernel) does not depend on pciutils, but the
linux tool "cpupower" (managed in linux-tool-cpupower) depends on
pciutils
- pciutils depends on udev when available
- udev is provided by systemd.
And indeed, during the build, we can see that make warns (it's only
reported as a *warning*, not as an actual error):
[...]
make[1]: Circular /home/ymorin/dev/buildroot/O/build/openssl-1.0.2h/.stamp_configured
<- cryptodev-linux dependency dropped.
>>> openssl 1.0.2h Downloading
[...]
So the build fails later on, when openssl is actually built:
eng_cryptodev.c:57:31: fatal error: crypto/cryptodev.h: No such file or directory
compilation terminated.
<builtin>: recipe for target 'eng_cryptodev.o' failed
Furthermore, graph-depends also detects the circular dependency, but
treats it as a hard-error:
Recursion detected for : cryptodev-linux
which is a dependency of: openssl
which is a dependency of: libcurl
which is a dependency of: systemd
which is a dependency of: udev
which is a dependency of: pciutils
which is a dependency of: linux
which is a dependency of: cryptodev-linux
Makefile:738: recipe for target 'graph-depends' failed
Of course, there is no way to break the loop without losing
functionality in either one of the involved packages *and* keep
our infrastructure and packages as-is.
The only solution is to break the loop at the linux-tools level, by
moving them away into their own package, so that the linux package will
no longer have the opportunity to depend on another package via a
dependency of one the tools.
All three linux tools are thus moved away to their own package.
The package infrastructure only knows of three types of packages: those
in package/ , in boot/ , in toolchain/ and the one in linux/ . So we
create that new linux-tools package in package/ so that we don't have to
fiddle with yet another special case in the infra. Still, we want its
configure options to appear in the kernel's sub-menu.
So, we make it a prompt-less package, with only the tools visible as
options of that package, but without the usual dependency on their
master symbol; they only depend on the Linux kernel.
Furthermore, because the kernel is such a huge pile of code, we would
not be very happy to extract it a second time just for the sake of a few
tools. We can't extract only the tools/ sub-directory from the kernel
source either, because some tools have hard-coded path to includes from
the kernel (arch and stuff).
Instead, we just use the linux source tree as our own build tree, and
ensure the linux tree is extracted and patched before linux-tools is
configured and built.

We used to do a special handling of Linux kernel modules when stripping
target binaries because there's some special precious data in modules
that we must keep for them to properly operate. This is for example true
for stack unwinding data etc.
It turned out there're cases when our existing "strip --strip-unneeded"
doesn't work well. For example this removes .debug_frame section used by
Linux on ARC for stack unwinding, refer to [1] and [2] for more details.
Now Linux kernel may strip modules as a part of "modules_install" target
if INSTALL_MOD_STRIP=1 is passed in command line. And so we'll do
allowing kernel decide how to strip modules in the best way.
Still note as of today Linux kernel strips modules uniformly for all
arches with "strip" command, so this commit alone doesn't solve
mentioned problem but it opens a possibility to add later a patch to the
kernel which will strip modules for ARC differently - and that's our
plan for mainline kernel.

This reverts commit 73da2ff6f7.
The reason for adding support for a local location was to be able to do
development on the Linux kernel source tree on a local directory rather
than have to clone it for every build.
We already have a mechanism for that, it's called override-srcdir. It's
been available since September 2011, more than a year before this patch
was committed.
Otherwise, we're going to be adding support for local sources in other
packages. First was U-Boot as submitted by Adam. But what next? We can't
have such support for all packages, especially since override-srcdir
does the job.
Besides, using a local source tree makes the build non-reproducible, so
we don't really want to have this in a .config (or defconfig).
We only handle the boolean option in legacy, as there is nothing we can
do with the directory path.

The cpupower linux tool needs gettext, always (even without locales).
We need to disable NLS, otherwise it tries to compile the .po files.
We also need to pass -lintl, otherwise it forgets to link with it
(because, the world is glibc-only, you did not know? And glibc does not
need we link with -lintl, so why would we? Oh, yes, we also reinvented
our super intelligent one-off Makefile rather than use one of the
standard buildsystems).
