kernel.bbclass: improve reproducibility

2018-04-03T22:53:19+00:00

Set KBUILD_BUILD_VERSION=1 to avoid build version being incremented on every build. It is visible in the output of "cat /proc/version" after the hash character. (From OE-Core rev: 7fa32ee42c3320e9e2b24ef747e43484b719f617) Signed-off-by: Jonathan Liu Signed-off-by: Richard Purdie

kernel.bbclass: set HOSTLDFLAGS in KCONFIG_CONFIG_COMMAND

2018-03-20T09:59:32+00:00

Kernel v4.14 and newer contain the following in their Makefile: HOST_LFS_LDFLAGS := $(shell getconf LFS_LDFLAGS) HOSTLDFLAGS := $(HOST_LFS_LDFLAGS) This breaks our menuconfig, because it can no longer find ncurses if its not on the host machine. This can be seen in linux-yocto-dev, for example: [clsulliv@clsulliv build]$ bitbake virtual/kernel -c menuconfig GEN ./Makefile HOSTLD scripts/kconfig/mconf /home/clsulliv/yocto/poky/build/tmp/hosttools/ld: cannot find -lncurses /home/clsulliv/yocto/poky/build/tmp/hosttools/ld: cannot find -ltinfo collect2: error: ld returned 1 exit status make[3]: *** [scripts/Makefile.host:99: scripts/kconfig/mconf] Error 1 make[2]: *** [/home/clsulliv/yocto/poky/build/tmp/work-shared/intel-corei7-64/kernel-source/Makefile:504: menuconfig] Error 2 make[1]: *** [Makefile:146: sub-make] Error 2 make: *** [Makefile:24: __sub-make] Error 2 Command failed. Press any key to continue... Fix this by setting HOSTLDFLAGS to ${BUILD_LDFLAGS} in our 'make menuconfig' command.

classes/recipes: Use expanded BUILD_REPRODUCIBLE_BINARIES value

2018-03-12T22:06:32+00:00

Replace the occurences of BUILD_REPRODUCIBLE_BINARIES with expanded values ${BUILD_REPRODUCIBLE_BINARIES} so the variable does not need to be exported. (From OE-Core rev: 27f87bbc8395a2481ef808465a62d213a6b678ac) Signed-off-by: Juro Bystricky Signed-off-by: Richard Purdie

kernel: make copying of crtsavres.o conditional

2018-03-08T23:28:04+00:00

As of the 4.13 kernel, there are configuration + linker combinations that do not need (or build) crtsavres.o for ppc64 targets. The commit of interest is: commit efe0160cfd40a99c052a00e174787c1f4158a9cd Author: Nicholas Piggin Date: Fri May 12 01:56:52 2017 +1000 powerpc/64: Linker on-demand sfpr functions for modules For final link, the powerpc64 linker generates fpr save/restore functions on-demand, placing them in the .sfpr section. Starting with binutils 2.25, these can be provided for non-final links with --save-restore-funcs. Use that where possible for module links. This saves about 200 bytes per module (~60kB) on powernv defconfig build. Signed-off-by: Nicholas Piggin Signed-off-by: Michael Ellerman As such, our arch test for crtsavres.o is not enough, we add a secondary existence check before trying the copy.

kernel.bbclass: explicitly depend on bison-native for deterministic builds

2018-02-24T10:31:47+00:00

Explicitly depend on bison-native for deterministic builds, as it is required for the build: | HOSTCC scripts/basic/fixdep | GEN ./Makefile | HOSTCC scripts/kconfig/conf.o | YACC scripts/kconfig/zconf.tab.c | /bin/sh: bison: command not found | scripts/Makefile.lib:217: recipe for target 'scripts/kconfig/zconf.tab.c' failed In most cases, this dependency comes indirectly via toolchain dependencies, specifically binutils-cross, which pulls bison-native. Different setups, such as with external toolchain, would expose this problem, since correct dependency is not marked explicitly.

meta: don't use deprecated functions from utils.bbclass

2018-01-30T11:50:11+00:00

These functions were moved to meta/lib/oe in 2010 and the base_* functions in utils.bbclass were intended to be a short-term compatibility layer. They're still used in a few places, so update the callers to use the new functions.

kernel: Use KERNEL_IMAGETYPE_FOR_MAKE in do_bundle_initramfs

In the case of a fitImage the this step should be done on the image use to assemble the fitImage. (From OE-Core rev: a061c6bfd3a049a2c8d14bcfafd6e1837afb95e5) Signed-off-by: Thomas Perrot Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

kernel: drop unnecessary True options from calls to getVar

2018-01-19T12:37:13+00:00

The older style calls (plus a bashism in kernel.bbclass, fixed separately) were introduced via the recent change to add support for multiple kernel packages: http://git.openembedded.org/openembedded-core/commit/?id=6c8c899849d101fd1b86aad0b8eed05c7c785924 (From OE-Core rev: e660ef68de3b3891a26ed6e10d96dc4efaf03ffc) Signed-off-by: Andre McCurdy Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

kernel.bbclass: drop legacy fallback to yes '' | make oldconfig

2018-01-18T12:50:36+00:00

The "oldnoconfig" target has been supported since Linux 2.6.36. According to OLDEST_KERNEL, the oldest kernel currently supported by OE is 3.2.0, so the fallback to yes '' | make oldconfig is no longer required.

kernel.bbclass: remove bashism in kernel_do_install

2018-01-14T09:11:57+00:00

possible bashism in run.do_install line 163 (should be 'b = a'): if [ "kernel" == "kernel" ]; then Fixes "[: kernel: unexpected operator" when not using bash by default, which causes the default kernel image link to not be created.
