Sun, 19 Feb 2023 14:15:52 +0000

sh: Fix -Wmissing-include-dirs warnings for various platformsThe 0day bot reports a lot of warnings (or errors due to CONFIG_WERROR)like this: cc1: error: arch/sh/include/mach-hp6xx: No such file or directory [-Werror=missing-include-dirs]Indeed, arch/sh/include/mach-hp6xx does not exist.While -Wmissing-include-dirs is only a W=1 warning, it may beannoying when CONFIG_BTRFS_FS is enabled because fs/btrfs/Makefileunconditionally adds this warning option.arch/sh/Makefile defines machdir-y for two purposes: - Build platform code in arch/sh/boards/mach-*/ - Add arch/sh/include/mach-*/ to the header search pathFor the latter, some platforms use arch/sh/include/mach-common/instead of having its own arch/sh/include/mach-*/.Drop unneeded machdir-y to omit non-existing include directories.To build arch/sh/boards/mach-*/, use the standard obj-y syntax inarch/sh/boards/Makefile.Reported-by: kernel test robot Link: https://lore.kernel.org/oe-kbuild-all/202302190641.30VVXnPb-lkp@intel.com/Signed-off-by: Masahiro Yamada Acked-by: Randy Dunlap Tested-by: Randy Dunlap Reviewed-by: John Paul Adrian Glaubitz Link: https://lore.kernel.org/r/20230219141555.2308306-1-masahiroy@kernel.orgSigned-off-by: John Paul Adrian Glaubitz List of files: /linux-6.15/arch/sh/Makefile

ce697cce - kbuild: remove head-y syntax

Sat, 24 Sep 2022 18:19:15 +0000

kbuild: remove head-y syntaxKbuild puts the objects listed in head-y at the head of vmlinux.Conventionally, we do this for head*.S, which contains the kernel entrypoint.A counter approach is to control the section order by the linker script.Actually, the code marked as __HEAD goes into the ".head.text" section,which is placed before the normal ".text" section.I do not know if both of them are needed. From the build systemperspective, head-y is not mandatory. If you can achieve the proper codeplacement by the linker script only, it would be cleaner.I collected the current head-y objects into head-object-list.txt. It isa whitelist. My hope is it will be reduced in the long run.Signed-off-by: Masahiro Yamada Tested-by: Nick Desaulniers Reviewed-by: Nicolas Schier List of files: /linux-6.15/arch/sh/Makefile

8212f898 - kbuild: use more subdir- for visiting subdirectories while cleaning

Wed, 13 Oct 2021 06:36:22 +0000

kbuild: use more subdir- for visiting subdirectories while cleaningDocumentation/kbuild/makefiles.rst suggests to use "archclean" forcleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement.Since commit d92cc4d51643 ("kbuild: require all architectures to havearch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick forall architectures. This can take advantage of the parallel option (-j)for "make clean".I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep"target no longer exists.Signed-off-by: Masahiro Yamada Reviewed-by: Kees Cook Acked-by: Geert Uytterhoeven Acked-by: Michael Ellerman (powerpc) List of files: /linux-6.15/arch/sh/Makefile

arch: use cross_compiling to check whether it is a cross build or not'cross_compiling' is defined by the top Makefile and available forarch Makefiles to check whether it is a cross build or not. A goodthing is the variable name 'cross_compiling' is self-documenting.This is a simple replacement for m68k, mips, sh, for which $(ARCH)and $(SRCARCH) always match.No functional change is intended for xtensa, either.This is rather a fix for parisc because arch/parisc/Makefile definesUTS_MATCHINE depending on CONFIG_64BIT, therefore cc-cross-prefixis not working in Kconfig time.Signed-off-by: Masahiro Yamada Acked-by: Geert Uytterhoeven Acked-by: Helge Deller # pariscAcked-by: Max Filippov # xtensa List of files: /linux-6.15/arch/sh/Makefile

9cc342f6 - treewide: prefix header search paths with $(srctree)/

Mon, 13 May 2019 06:22:16 +0000

treewide: prefix header search paths with $(srctree)/Currently, the Kbuild core manipulates header search paths in a crazyway [1].To fix this mess, I want all Makefiles to add explicit $(srctree)/ tothe search paths in the srctree. Some Makefiles are already written inthat way, but not all. The goal of this work is to make the notationconsistent, and finally get rid of the gross hacks.Having whitespaces after -I does not matter since commit 48f6e3cf5bc6("kbuild: do not drop -I without parameter").[1]: https://patchwork.kernel.org/patch/9632347/Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/sh/Makefile

So, CONFIG_SUPERH32 is never set during the configuration,then cayman_defconfig is always chosen.This commit provides a sensible way to choose shx3/cayman_defconfig.arch/sh/Kconfig sets either SUPERH32 or SUPERH64 depending on ARCHenvironment, like follows: config SUPERH32 def_bool ARCH = "sh" ... config SUPERH64 def_bool ARCH = "sh64"It should make sense to choose the default defconfig by ARCH,like arch/sparc/Makefile.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/sh/Makefile

5a846aba - sh: add support for J-Core J2 processor

Thu, 17 Mar 2016 23:09:37 +0000

sh: add support for J-Core J2 processorAt the CPU/ISA level, the J2 is compatible with SH-2, and thus thechanges to add J2 support build on existing SH-2 support. However, J2does not duplicate the memory-mapped SH-2 features like the cacheinterface. Instead, the cache interfaces is described in the devicetree, and new code is added to be able to access the flat device treeat early boot before it is unflattened.Support is also added for receiving interrupts on trap numbers in therange 16 to 31, since the J-Core aic1 interrupt controller generatesthese traps. This range was unused but nominally for hardwareexceptions on SH-2, and a few values in this range were used forexceptions on SH-2A, but SH-2A has its own version of the relevantcode.No individual cpu subtypes are added for J2 since the intent movingforward is to represent SoCs with device tree rather than ashard-coded subtypes in the kernel. The CPU_SUBTYPE_J2 Kconfig itemexists only to fit into the existing cpu selection mechanism until itis overhauled.Signed-off-by: Rich Felker List of files: /linux-6.15/arch/sh/Makefile
