* build: create $(PKG_SYMVERS_DIR) if non-existentSebastian Kemper2020-11-191-0/+1
| | | | | | | | | | | | | Commit 5d76065 moved the creation of the symvers directory to include/kernel-build.mk. This is fine when building from scratch. But when unpacking an SDK the directory doesn't exist and because the kernel won't be built (again) this directory will not be created by the build system, causing build failure if make tries to copy files into it. This moves the creation of the symvers directory back into include/kernel.mk so that the directory is created in any case. Signed-off-by: Sebastian Kemper <sebastian_ml@gmx.net>
* build: pass KBUILD_EXTRA_SYMBOLS with symvers files for kernel module packagesFelix Fietkau2020-11-131-10/+2
| | | | | | | This replaces the previous (deprecated) method of collecting symvers data in $(PKG_BUILD_DIR)/Module.symvers, which does not work on newer kernels Signed-off-by: Felix Fietkau <nbd@nbd.name>
* build: move symvers files to kernel build dirFelix Fietkau2020-04-091-4/+6
| | | | | | | | | | The symvers files of older kernel versions are incompatible with the ones from 5.4, so changing the kernel version without running make clean was causing build failures in kernel module packages. Fix this by moving the directory, ensuring that symvers files get thrown away with a kernel version change Signed-off-by: Felix Fietkau <nbd@nbd.name>
* build: Add KBUILD_HOSTLDLIBSHauke Mehrtens2020-01-261-0/+1
| | | | | | | | | | In Linux kernel commit 8377bd2b9ee1 ("kbuild: Rename HOST_LOADLIBES to KBUILD_HOSTLDLIBS") HOST_LOADLIBES was renamed to KBUILD_HOSTLDLIBS. This patch adapts the OpenWrt kernel build to this new variable. Without this change the kernel host tools would not link against the libraries found in the staging directory.

* kernel.mk: add KCFLAGS to make kmods reproduciblePaul Spooren2019-10-091-0/+1
| | | | | | | | | | | | Some kmods (gpio-hotplug, wireguard) store the build path in the compiled files and therefore make it harder to rebuild the official binaries. As the same "iremap" function is used as for other binaries, the change is compatible with gcc7 and 8. Tested with both gcc7 and gcc8 resulting in build path independent reproducible builds. Signed-off-by: Paul Spooren <mail@aparcar.org>
* build: force disable stack validation during kernel build on non-linux systemsFelix Fietkau2019-10-021-1/+2
| | | | | | | | | | | The check for libelf in the kernel build is not enough, because the code that uses libelf for stack validation is completely non-portable, as it tries to include asm/types.h and relies on kernel types in user space. Until this is fixed properly, the only solution is to disable this on any non Linux build host Signed-off-by: Felix Fietkau <nbd@nbd.name>
* build: include BUILD_VARIANT in PKG_BUILD_DIRJeffery To2019-08-051-1/+1
| | | | | | | | | | | This changes the default PKG_BUILD_DIR to take BUILD_VARIANT into account (if set), so that packages do not need to manually override PKG_BUILD_DIR just to handle variants. This also updates most base packages with variants to use the updated default PKG_BUILD_DIR. Signed-off-by: Jeffery To <jeffery.to@gmail.com>
* build: skip kernel stack validation when building on macOSFelix Fietkau2019-07-031-0/+4
| | | | | | | | | | Since we switched to 4.19, the kernel build checks for libelf to decide if it should build tools for stack validation. On macOS, this check fails during target/compile, but succeeds during package build (because of the pkg-config path picking up target libraries). Signed-off-by: Felix Fietkau <nbd@nbd.name>
* build: fix external module symbol collection if build_dir is a symlinkRoman Yeryomin2019-06-061-1/+4
| | | | | | | | | | | | | | | | e26ffb31dfa30d498b963a86d231835e3af7d3df fixed only embedded modules symbol collection. If we are building external modules, like broadcom-wl or lantiq dsl stuff then modules which do EXPORT_SYMBOL have unresolved paths in Module.symvers and external module which depend on other external modules will have empty dependencies, leading to broken module loading. This was discussed on IRC with Jonas some time ago. Fix this by handling both resolved and unresolved paths.

* include/kernel: sort autoload modules list to fix reproducible buildsAlexander Couzens2019-02-281-1/+1
| | | | | | | | When autoloading more than one modules per packages, /etc/modules.d/$module depends on the file system ordering. To test this: use disorderfs on the build_dir and build kmod-sched. Signed-off-by: Alexander Couzens <lynxis@fe80.eu>
* build: fix build dependency of kmod .ipk with version filtered filesYousong Zhou2018-12-181-1/+1
| | | | | | | | | We need to use resolved file list as prerequisites for repacking kmod .ipk files. Note that currently version_filter uses a Makefile macro KERNEL_PATCHVER that should be available at ipk building time.

* include/kernel.mk: build kmod packages with empty FILESMatthias Schiffer2018-04-121-4/+2
| | | | | | | | | | | kmod packages without FILES did not have an install step defined, leading to no package being built. This affected netfilter/iptables packages, which filter out builtin modules from FILES. Not building a package that it is selected in .config is problematic, as the generated empty package may be necessary to satisfy dependencies.

* build: fix module symbol collection if build_dir is a symlinkJonas Gorski2017-11-071-1/+1
| | | | | | | | | | | | If PKG_BUILD_DIR contains symlinks, the generated Module.symvers will contain the resolved paths, not the virtual path with the symlink name. This breaks the filter for the module's own symbols, so to fix this ensure we also grep for the resolved path.

* include: kernel.mk: simplify module autoloadingJo-Philipp Wich2017-11-071-51/+21
| | | | | | | | | | | | | | | | | | Let the generic postinstall script invoke "kmodloader" when the just installed package contains any /etc/module.d/ entries. This allows us to skip the explicit "insert_module()" calls in the package postinstall. Due to the removed insert_module calls we do not need to assemble a complete list of modules per package anymore, which allows for vast simplification of the package generation code. While we're at it, also support specifying default parameters for modules using either the MODPARAM or MODPARAM.modulename variables in KernelPackage. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

* build: ensure PKG_INFO_DIR exists before trying to use itJonas Gorski2017-10-281-0/+1
| | | | | | | | | | | PKG_INFO_DIR is only created at the finish step of the first package build, but kernel modules now use it at the start. Doing a parallel build could cause a kernel module to be the first package, breaking the build. Fix this by ensuring the directory exists.

| | | | | | | | | | | | When an external kernel tree is used the version should not get modified by the LEDE build scripts. This was added by Florian some time ago. The commit 0aed054becb21439 ("build: add KERNEL_MAKE and KERNEL_MAKE_FLAGS variables and move to kernel.mk") breaks this feature introduced in b6746a6ffb73 ("include: Do not alter KERNELRELEASE for external/git kernels").

* include: Determine MODULES_DIR correctly for external/git kernelsFlorian Fainelli2017-05-251-3/+5
| | | | | | | | | | | | | | When using external or git cloned kernels, any kind of modifications will alter KERNELRELEASE. LEDE still tries to stage modules in lib/modules/$(LINUX_UNAME_VERSION) and LINUX_UNAME_VERSION is based on KERNEL_PATCHVER (indirectly) so this does not work, and we lose all kinds of automatic modules loading. To remedy that, just cat $(LINUX_DIR)/include/config/kernel.release which is late enough the kernel has prepared this file, and is correctly tracking changes done throughout the kernel.

* linux: add support of Synopsys ARC770-based boardsFelix Fietkau2015-11-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces support of new boards with ARC cores. [1] Synopsys SDP board This is a new-generation development board from Synopsys that consists of base-board and CPU tile-board (which might have a real ASIC or FPGA with CPU image). It sports a lot of DesignWare peripherals like GMAC, USB, SPI, I2C etc and is intended to be used for early development of ARC-based products. [2] nSIM This is a virtual board implemented in Synopsys proprietary software simulator (even though available for free for open source community). This board has only serial port as a peripheral and so it is meant to be used for runtime testing which is especially useful during bring-up of new tools and platforms. What's also important ARC cores are very configurable so there're many variations of options like cache sizes, their line lengths, additional hardware blocks like multipliers, dividers etc. And this board could be used to make sure built software still runs on different HW configurations.
