* build: skip headers install and config on make target/linux/prepareFelix Fietkau2017-02-151-1/+1
| | | | | | This simplifies working with quilt on the kernel tree Signed-off-by: Felix Fietkau <nbd@nbd.name>
* git-kernel: $(SUBDIR) should always be $(LINUX_VERSION)Mirko Vogt2017-01-181-1/+1
| | | | | | | | | | | | | | | | | | Before SUBDIR was set to $(PATCHVER) which may or may not include the minor version number of the linux kernel version. Usually it doesn't. So the git-clone'd linux kernel was packed without the minor version number taken into account, which broke further processing, as it expected the extracted dir being named linux-$(LINUX_VERSION) (=with minor version) rather than linux-$(PATCHVER) (=without minor version). Changing SUBDIR to $(LINUX_VERSION) creates consistent behaviour here. Signed-off-by: Mirko Vogt <mirko-openwrt@nanl.de>
* treewide: clean up download hashesFelix Fietkau2016-12-161-1/+1
| | | | | | Replace *MD5SUM with *HASH, replace MD5 hashes with SHA256 Signed-off-by: Felix Fietkau <nbd@nbd.name>
* include/kernel: Switch to git download methodFlorian Fainelli2016-12-041-0/+19
| | | | | | | | | Utilize the existing git download logic from include/download.mk and migrate the kernel download over to it. This avoids repeatedly cloning kernel sources after a make target/linux/clean for instance.

* build: fix regression on running make kernel_menuconfigFelix Fietkau2016-10-041-1/+1
| | | | | | | | The build system overrides HOST_LOADLIBES to add the staging dir to the library search path. menuconfig needs -lncurses, add another override for it. Signed-off-by: Felix Fietkau <nbd@nbd.name>
* kernel: check the right directories for rebuildJonas Gorski2016-08-191-1/+1
| | | | | | | | | | | | Pass KERNEL_FILE_DEPENDS to rdep instead of PKG_FILE_DEPENDS, which is empty. Also don't pass $(CURDIR) as the directory to timestamp, as it would also pick up non kernel related changes like image building code. Should fix kernel being rebuild for unrelated changes, as well as not being rebuild for changes in target/linux/generic.

* build system: have tar use $SOURCE_DATE_EPOCH for --mtimeFelix Fietkau2016-01-311-1/+3
| | | | | | | | | | | | | | | | The --mtime argument to 'tar' sets the modification time for all files within the archive, which determines the timestamp files will get when they are extracted. In this case, rootfs and other tarballs will get mtimes which correspond to the last commit timestamp of the build system, as reported by git/subversion. This is a step towards reproducible image builds.

* kernel-build: fix STRIP_KERNEL_EXPORTS for recent kernelsJohn Crispin2014-09-151-1/+1
| | | | | | | | | | Recent kernels started to mark exported symbols as global. Adapt expressions in kernel-build.mk to also match global symbols when grep'ing through nm output. Signed-off-by: Daniel Golle <daniel@makrotopia.org> SVN-Revision: 42555
* include: fix kernel download failure with git & local treesJohn Crispin2014-06-021-1/+1
| | | | | | | | | | | | | | | | | | When using the options EXTERNAL_KERNEL_TREE or KERNEL_GIT_CLONE_URI, the command "make downloads" fails as it tries to download the kernel tarball despite the option. This doesn't happen during a regular build as in that case, the dependency is conditionned through the LINUX_SITE variable, which is not set in these cases. Below is a snapshot of the error for an target using a 3.14 kernel: make[3]: *** No rule to make target `.../dl/linux-3.14.tar.xz', needed by `download'. Stop.

* build: speed up kernel symbol export strippingFelix Fietkau2013-12-141-3/+3
| | | | | | | | | | GNU grep has a high per-expression setup overhead when compiling regular expressions. Use -F to force it to interpret the input as fixed strings, which is much faster (fraction of a second instead of multiple minutes). Signed-off-by: Felix Fietkau <nbd@openwrt.org> SVN-Revision: 39049
