This works well if you configure # and build the kernel on the same host machine. # # It is inconvenient if you prepare the .config that is carried to a # different build environment (typically this happens when you package # the kernel for distros) because using a different compiler potentially # produces different CONFIG options than the real build environment. # So, you probably want to make as many options visible as possible. # In other words, you need to create a super-set of CONFIG options that # cover any build environment. If some of the CONFIG options turned out # to be unsupported on the build machine, they are automatically disabled # by the nature of Kconfig. # # However, it is not feasible to get a full-featured compiler for every # arch. # # This issue was discussed here: # # https://lkml.org/lkml/2019/12/9/620 # # Other than distros, savedefconfig is also a problem. Some arch sub-systems # periodically resync defconfig files. If you use a less-capable compiler # for savedefconfig, options that do not meet 'depends on $(cc-option,...)' # will be forcibly disabled. So, 'make defconfig && make savedefconfig' # may silently change the behavior. # # This commit adds a set of dummy toolchains that pretend to support any # feature. # # Most of compiler features are tested by cc-option, which simply checks # the exit code of $(CC). The dummy tools are shell scripts that always # exit with 0. So, $(cc-option, ...) is evaluated as 'y'. # # There are more complicated checks such as: # # scripts/gcc-x86_{32,64}-has-stack-protector.sh # scripts/gcc-plugin.sh # scripts/tools-support-relr.sh # # scripts/dummy-tools/gcc passes all checks. # # From the top directory of the source tree, you can do: # # $ make CROSS_COMPILE=scripts/dummy-tools/ oldconfig # # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # Reviewed-by: Philipp Rudo <prudo@linux.ibm.com> # Tested-by: Jeremy Cline <jcline@redhat.com> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 76426e238834f0927dee9925e8832179b8d56d6e # < make -s -j 24 ARCH=powerpc O=/kisskb/build/kbuild_pmac32_defconfig+SMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pmac32_defconfig # Added to kconfig CONFIG_SMP=y # < make -s -j 24 ARCH=powerpc O=/kisskb/build/kbuild_pmac32_defconfig+SMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/kbuild_pmac32_defconfig+SMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4080:warning: override: reassigning to symbol SMP # make -s -j 24 ARCH=powerpc O=/kisskb/build/kbuild_pmac32_defconfig+SMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:12:0, from /kisskb/src/sound/ppc/awacs.c:16: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:218:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0); ^ /kisskb/src/sound/ppc/awacs.c:873:36: note: 'speaker_vol' was declared here struct snd_kcontrol *master_vol, *speaker_vol; ^ ERROR: modpost: "sysrq_mask" [drivers/tty/serial/serial_core.ko] undefined! make[2]: *** [/kisskb/src/scripts/Makefile.modpost:94: __modpost] Error 1 make[1]: *** [/kisskb/src/Makefile:1302: modules] Error 2 make[1]: *** Waiting for unfinished jobs....
