1bbab483d30013e1a393dde547ff10fc4438b208 - bootconfig: clean build-time tools/bootconfig from make clean

Thu, 02 Jul 2026 14:15:45 +0200

bootconfig: clean build-time tools/bootconfig from make cleanThe previous patch builds tools/bootconfig during 'make prepare' torender the embedded bootconfig cmdline, but nothing removes it on'make clean', leaving the compiled tool and its objects behind.Wire a bootconfig_clean hook into the top-level clean target so thecompiled tool and its objects are removed by make clean, matching theprepare-wired tools/objtool and tools/bpf/resolve_btfids.The hook runs tools/bootconfig's Makefile via $(MAKE), which the kernelbuild invokes with -rR (MAKEFLAGS += -rR). -rR drops the built-in $(RM)variable, so the existing "$(RM) -f ..." clean recipe would expand to abare "-f ..." and fail. Spell the recipe with a literal "rm -f" so itkeeps working both standalone and when invoked from Kbuild.Link: https://lore.kernel.org/all/20260626-bootconfig_using_tools-v7-4-24ab72139c29@debian.org/Reviewed-by: Nicolas Schier Signed-off-by: Breno Leitao Signed-off-by: Masami Hiramatsu (Google) List of files: /linux/tools/bootconfig/Makefile

fc9d90470463f165a95becbfbad21795fd9752bd - bootconfig: render embedded bootconfig as a kernel cmdline at build time

Thu, 02 Jul 2026 14:15:45 +0200

bootconfig: render embedded bootconfig as a kernel cmdline at build timeAdd the build-time pipeline that renders the "kernel" subtree ofCONFIG_BOOT_CONFIG_EMBED_FILE into a flat cmdline string and stashesit in .init.rodata as embedded_kernel_cmdline[]. A follow-up patchadds the runtime helper that prepends this string to boot_command_lineduring early architecture setup so parse_early_param() sees the values.The build wires up: tools/bootconfig -C kernel - userspace tool already shared with lib/bootconfig.c, used here in -C mode to render a bootconfig file to a cmdline lib/embedded-cmdline.S - .incbin's the rendered text plus a NUL (listed under the EXTRA BOOT CONFIG MAINTAINERS entry) lib/Makefile rule - runs tools/bootconfig at build time Makefile prepare dep - ensures tools/bootconfig is built first, same pattern as tools/objtool and tools/bpf/resolve_btfidsDrop the test target from tools/bootconfig/Makefile's default 'all'recipe so that hooking the binary into the kernel build does not runtest-bootconfig.sh on every prepare. The tests stay available as'make -C tools/bootconfig test', matching the convention oftools/objtool and tools/bpf/resolve_btfids whose 'all' targets onlybuild the binary.Require BOOT_CONFIG_EMBED_FILE to be non-empty before the new optioncan be enabled, otherwise tools/bootconfig -C runs against an emptyfile and prints a parse error on every kernel build.The feature gates on CONFIG_ARCH_SUPPORTS_CMDLINE_FROM_BOOTCONFIG, asilent symbol arches select once they've wired the prepend call intosetup_arch(). No arch selects it in this patch, so the user-visibleCONFIG_CMDLINE_FROM_BOOTCONFIG is not yet enableable; when an archlater opts in, the runtime behavior is added by the follow-up patches.tools/bootconfig also installs on target systems, so its own Makefilekeeps $(CC) and stays cross-buildable as a standalone tool. The kernelbuild, which runs the tool on the build host during prepare, insteadforces CC=$(HOSTCC) from a dedicated tools/bootconfig rule and clearsCROSS_COMPILE= in the sub-make. Without that clear, an LLVM=1 crossbuild would inherit CROSS_COMPILE and tools/scripts/Makefile.includewould inject --target=/--sysroot= flags into the host clang invocation,producing a target binary that fails to exec ("Exec format error").embedded-cmdline.S places the rendered string in its own .init.rodatasubsection (.init.rodata.embed_cmdline) with the "a" (allocatable,read-only) flag and %progbits. lib/bootconfig-data.S already placesthe embedded bootconfig blob in .init.rodata with the "aw" flag(xbc_init() rewrites separators in place, so that data must bewritable). Using a distinct subsection name avoids the ld.lld section-type mismatch that would otherwise arise from mixing "a" and "aw"under the same name; the linker's "*(.init.rodata .init.rodata.*)"glob still folds both into the init image and frees them after boot.A follow-up patch wires the build-time tools/bootconfig into thetop-level clean target.Link: https://lore.kernel.org/all/20260626-bootconfig_using_tools-v7-3-24ab72139c29@debian.org/Reviewed-by: Nicolas Schier Signed-off-by: Breno Leitao Signed-off-by: Masami Hiramatsu (Google) List of files: /linux/tools/bootconfig/Makefile
