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/openrisc/Makefile

87e387ac - openrisc: Add gcc machine instruction flag configuration

Sat, 22 Jan 2022 04:32:38 +0000

openrisc: Add gcc machine instruction flag configurationOpenRISC GCC supports flags to enable the backend to output instructionsif they are supported by a target processor. This patch addsconfiguration flags to enable configuring these flags to tune the kernelfor a particular CPU configuration.In the future we could also enable all of these flags by default andprovide instruction emulation in the kernel to make these choices easierfor users but this is what we provide for now.Signed-off-by: Stafford Horne List of files: /linux-6.15/arch/openrisc/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/openrisc/Makefile

kbuild: add endianness flag to CHEKCFLAGSThe kernel depends on macros like __BYTE_ORDER__,__BIG_ENDIAN__ or __LITTLE_ENDIAN__.OTOH, sparse doesn't know about the endianness of the kernel andby default uses the same as the machine on which sparse was built.Ensure that sparse can predefine the macros corresponding tohow the kernel was configured by adding -m{big,little}-endianto CHECKFLAGS in the main Makefile (and so for all archs).Also, remove the equivalent done in arch specific Makefiles.Signed-off-by: Luc Van Oostenryck Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/openrisc/Makefile
