linux: add 'Image' as the image name for aarch64

2015-10-05T14:01:32+00:00

On aarch64, the image name is always Image, so let's add support for that. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Peter Korsgaard

linux: install dtc binary as linux-dtc

2015-10-04T18:17:35+00:00

So it doesn't conflict with host-dtc. The Linux kernel version may be a patched version supporting E.G. overlays. Signed-off-by: Peter Korsgaard

core/pkg-kernel-module: ensure linux supports modules

2015-09-04T11:13:52+00:00

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). Suggested-by: Peter Korsgaard Signed-off-by: "Yann E.

linux: enable all options needed by xtables-addons

2015-08-23T19:01:51+00:00

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.

package/linux: trash stderr in LINUX_VERSION_PROBED

2015-07-22T15:25:25+00:00

The Linux buildsystem tries to run the compiler even just for 'kernelrelease' (which we store in LINUX_VERSION_PROBED) and we sometimes need to use it before the toolchain is available; thus we get spurious errors on stderr. Consign stderr to oblivion when computing the 'kernelrelease'. Signed-off-by: "Yann E. MORIN" Signed-off-by: Thomas Petazzoni

linux: use backtick instead of $(shell ...) make function

2015-07-14T22:42:01+00:00

Verified that LINUX_VERSION_PROBED is only used in "-quoted commands (actually, usually it's not quoted). Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni

linux: add linux-tools infra

2015-07-14T21:21:51+00:00

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.

package/linux: check for config file before calling kconfig-package

2015-07-14T08:27:52+00:00

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 tests were located.] Signed-off-by: "Yann E.
