Currently, the linux.mk logic for appended DTB image does the
appending of the DTB in place, directly at the end of the zImage using
a >> sign. This is incorrect because if you run "make linux-rebuild"
multiple times, you get the DTB appended over and over again to the
image.
Since keeping the 'zImage' or 'uImage' name for the appended DTB image
is not very clear, this commit moves to using the 'zImage.<dtb>' and
'uImage.<dtb>' format. This way, we can clearly distinguish the
original image from the appended one.
In addition, this naming scheme easily allows to generate *multiple*
appended DTB images: from one zImage, you can generate multiple
zImage.<dtb> for several DTBs, and then generate (if requested) the
corresponding uImage.<dtb>.
To achieve this, this commit:
- Changes the definition of LINUX_APPENDED_DTB to iterate over
$(KERNEL_DTS_NAME), and generate a zImage.<dtb> image for each of
them.
- Changes the addition of LINUX_APPENDED_DTB for appended uImage to
also iterate over $(KERNEL_DTS_NAME).
- Provide a different implementation of LINUX_INSTALL_IMAGE which
installs all the appended DTB images (but not the bare image)
- Remove the checks that verified that only one DT name is passed
when appended DTB is used, since we now support generating multiple
DT images.
Some of the tested configuration:
- Normal uImage with several DTBs
BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7"

When you're using the "appended DTB" mode, the Device Tree blob gets
appended to your kernel image, so there is no point in installing both
the DTB and the kernel image to the images or target directories,
installing the kernel image itself is sufficient.
Therefore, this commit disables the definition of LINUX_INSTALL_DTB
when appended DTB is used.

Currently, the LINUX_INSTALL_DTB and LINUX_INSTALL_DTB_TARGET macros
are exactly the same, except for the target directory.
Similarly, LINUX_INSTALL_KERNEL_IMAGE_TO_TARGET and
LINUX_INSTALL_IMAGES_CMDS are copying the kernel image, just to a
different place (and with a different strategy).
As a preparation for future additions, this commit de-duplicate this
code:
- LINUX_INSTALL_DTB becomes a make macro that takes one argument: the
destination directory.
- LINUX_INSTALL_IMAGE is a new make macro that also takes on
argument: the destination directory.
Both macros are used by LINUX_INSTALL_KERNEL_IMAGE_TO_TARGET and
LINUX_INSTALL_IMAGES_CMDS to respectively install to the target
directory and the images directory.

When a package wants to build a kernel module, we should ensure that the
kernel does support modules.
This patch does it automatically for packages using the kernel-module
infrastructure.
Packages that do not use it will have to set it manually (to be done in
a followup patch).

Both of CONFIG_NF_CONNTRACK and CONFIG_NF_CONNTRACK_MARK are needed by
xtables-addons.
Although the current code does enable them in the linux' .config file,
the former is protected behind CONFIG_NETFILTER_ADVANCED, which may be
missing from a user-supplied (def)config file, and is missing from some
of the bundled defconfigs as well.
For example, the following defconfig fails to build:
BR2_TOOLCHAIN_EXTERNAL=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_DEFCONFIG="i386"
BR2_PACKAGE_XTABLES_ADDONS=y
So, also force-enable CONFIG_NETFILTER_ADVANCED.

The Linux buildsystem tries to run the compiler even just for
'kernelrelease' (which we store in LINUX_VERSION_PROBED) and we

This commit add an infrastructure to build linux kernel
tools available in the kernel sources.
Currently, the only linux kernel tool packaged in Buildroot
is perf and it's packaged as a separate generic package.
This is a problem for licence information raised in this
thread [1].
Since these tools require to build a Linux kernel, we can
use some hooks in linux package like we did for linux
extensions [2] and remove the perf package.

If we check that the user provides a config file after we call to the
kconfig-package infra, the error message we get is the one for the
kconfig-package infra, not the custom error message we want to show to
the user.
So, only call kconfig-package after we do the check. Move the check with
the existing checks for the DTS, for consistency.
[Thomas: put the checks together, but right before the kconfig-package
call, rather than in the middle of the code, were the DTS related

The ktap package requires some parts of the kernel tracing
infrastructure to be enabled, especially
CONFIG_EVENT_TRACING. However, this option is a blind option in the
kernel, so enabling it in linux.mk has no effect: we need to enable a
non-blind option that selects CONFIG_EVENT_TRACING. We've chosen to
select CONFIG_ENABLE_DEFAULT_TRACERS.
This fixes the build of ktap.
[Thomas: use CONFIG_ENABLE_DEFAULT_TRACERS as suggested by Arnout.]

This commit removes BR2_LINUX_KERNEL_EXT_RTAI_PATCH because this
option never worked. It was added in commit
8797a9cd1f, which added package/rtai/
and RTAI as a Linux extension.
The option prompt says "Path for RTAI patch file", so let's say you
specify /home/foo/bar/myrtai.patch as the value for
BR2_LINUX_KERNEL_EXT_RTAI_PATCH.
Then the code does:
RTAI_PATCH = $(call qstrip,$(BR2_LINUX_KERNEL_EXT_RTAI_PATCH))
and we have a package called 'rtai', so the normal logic of
<pkg>_PATCH applies. Since the <pkg>_PATCH value does not contain
ftp://, http:// or https://, the package infrastructure will try to
download $(RTAI_SITE)/$(RTAI_PATCH), i.e:
https://www.rtai.org/userfiles/downloads/RTAI/home/foo/bar/myrtai.patch
Pretty clear that it has no chance of working.
Now, let's assume an URL is used as the value of
BR2_LINUX_KERNEL_EXT_RTAI_PATCH, such as
http://foo.com/bar/myrtai.patch. In this case, it will be properly
downloaded by the package infrastructure. But then, the following code
kicks in:
define RTAI_PREPARE_KERNEL
$(APPLY_PATCHES) \
$(LINUX_DIR) \
$(dir $(RTAI_PATCH)) \
$(notdir $(RTAI_PATCH))
endef
The value of $(dir $(RTAI_PATCH)) will be http://foo.com/bar/. How
can $(APPLY_PATCHES) make use of such a stupid patch location?
[Thomas: add Config.in.legacy handling, as suggested by Arnout, even
if we believe that no-one could have ever used this option.]
