2021-12-02kconfig: Add `make mod2noconfig` to disable module optionsJosh Triplett1-1/+2
When converting a modular kernel to a monolithic kernel, once the kernel works without loading any modules, this helps to quickly disable all the modules before turning off module support entirely. Refactor conf_rewrite_mod_or_yes to a more general conf_rewrite_tristates that accepts an old and new state.

2021-04-14kconfig: use /boot/config-* etc. as DEFCONFIG_LIST only for native buildMasahiro Yamada1-4/+4
When the .config file is missing, 'make config', 'make menuconfig', etc. uses a file listed in DEFCONFIG_LIST, if found, as base configuration. Ususally, /boot/config-$(uname -r) exists, and is used as default. However, when you are cross-compiling the kernel, it does not make sense to use /boot/config-* on the build host. It should default to arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG). UML previously did not use DEFCONFIG_LIST at all, but it should be able to use arch/um/configs/$(KBUILD_DEFCONFIG) as a base config file. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: do not use allnoconfig_y optionMasahiro Yamada1-1/+2
allnoconfig_y is an ugly hack that sets a symbol to 'y' by allnoconfig. allnoconfig does not mean a minimal set of CONFIG options because a bunch of prompts are hidden by 'if EMBEDDED' or 'if EXPERT', but I do not like to hack Kconfig this way. Use the pre-existing feature, KCONFIG_ALLCONFIG, to provide a one liner config fragment. CONFIG_EMBEDDED=y is still forced when allnoconfig is invoked as a part of tinyconfig. No change in the .config file produced by 'make tinyconfig'. The output of 'make allnoconfig' will be changed; we will get CONFIG_EMBEDDED=n because allnoconfig literally sets all symbols to n.

2021-04-14kconfig: move default KBUILD_DEFCONFIG back to scripts/kconfig/MakefileMasahiro Yamada1-0/+4
This is a partial revert of commit 2a86f6612164 ("kbuild: use KBUILD_DEFCONFIG as the fallback for DEFCONFIG_LIST"). Now that the reference to $(DEFCONFIG_LIST) was removed from init/Kconfig, the default KBUILD_DEFCONFIG can go back home. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: change defconfig_list option to environment variableMasahiro Yamada1-0/+10
"defconfig_list" is a weird option that defines a static symbol that declares the list of base config files in case the .config does not exist yet. This is quite different from other normal symbols; we just abused the "string" type and the "default" properties to list out the input files. They must be fixed values since these are searched for and loaded in the parse stage. It is an ugly hack, and should not exist in the first place. Providing this feature as an environment variable is a saner approach. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-02-24kconfig: unify rule of config, menuconfig, nconfig, gconfig, xconfigMasahiro Yamada1-22/+14

2021-02-24kconfig: omit --oldaskconfig option for 'make config'Masahiro Yamada1-1/+1
scripts/kconfig/conf.c line 39 defines the default of input_mode as oldaskconfig. Hence, 'make config' works in the same way even without the --oldaskconfig option given. Note this in the help message. This will be helpful to unify build rules in Makefile in the next commit. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-08-26kbuild: hide commands to run Kconfig, and show short log for syncconfigMasahiro Yamada1-8/+8
Some targets (localyesconfig, localmodconfig, defconfig) hide the command running, but the others do not. Users know which Kconfig flavor they are running, so it is OK to hide the command. Add $(Q) to all commands consistently. If you want to see the full command running, pass V=1 from the command line. syncconfig is the exceptional case, which occurs without explicit command invocation by the user. Display the Kbuild-style log for it. The ugly bare log will go away.

2020-08-01kconfig: qconf: compile moc object separatelyMasahiro Yamada1-5/+6
Currently, qconf.moc is included from qconf.cc but they can be compiled independently. When you modify qconf.cc, qconf.moc does not need recompiling. Rename qconf.moc to qconf-moc.cc, and split it out as an independent compilation unit. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-01kconfig: qconf: use if_changed for qconf.moc ruleMasahiro Yamada1-2/+4
Regenerate qconf.moc when the moc command is changed. This also allows 'make mrproper' to clean it up. Previously, it was not cleaned up because 'clean-files += qconf.moc' was missing. Now 'make mrproper' correctly cleans it up because files listed in 'targets' are cleaned. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-05-25kconfig: announce removal of 'kvmconfig' and 'xenconfig' shorthandsMasahiro Yamada1-5/+4
kvmconfig' is a shorthand for kvm_guest.config to save 7 character typing. xenconfig' is a shorthand for xen.config to save 1 character typing. There is nothing more than that. There are more files in kernel/configs/, so it is not maintainable to wire-up every config fragment to the Kconfig Makefile. Hence, we should not do this at all. These will be removed after Linux 5.10. Meanwhile, the following warning message will be displayed if they are used. WARNING: 'make kvmconfig' will be removed after Linux 5.10 Please use 'make kvm_guest.config' instead. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-03-03kbuild: use KBUILD_DEFCONFIG as the fallback for DEFCONFIG_LISTMasahiro Yamada1-4/+0
Most of the Kconfig commands (except defconfig and all*config) read the .config file as a base set of CONFIG options. When it does not exist, the files in DEFCONFIG_LIST are searched in this order and loaded if found. I do not see much sense in the last two lines in DEFCONFIG_LIST. [1] ARCH_DEFCONFIG The entry for DEFCONFIG_LIST is guarded by 'depends on !UML'. So, the ARCH_DEFCONFIG definition in arch/x86/um/Kconfig is meaningless. arch/{sh,sparc,x86}/Kconfig define ARCH_DEFCONFIG depending on 32 or 64 bit variant symbols. This is a little bit strange; ARCH_DEFCONFIG should be a fixed string because the base config file is loaded before the symbol evaluation stage. Using KBUILD_DEFCONFIG makes more sense because it is fixed before Kconfig is invoked. Fortunately, arch/{sh,sparc,x86}/Makefile define it in the same way, and it works as expected. Hence, replace ARCH_DEFCONFIG with "arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG)". [2] arch/$(ARCH)/defconfig This file path is no longer valid. The defconfig files are always located in the arch configs/ directories. $ find arch -name defconfig | sort arch/alpha/configs/defconfig arch/arm64/configs/defconfig arch/csky/configs/defconfig arch/nds32/configs/defconfig arch/riscv/configs/defconfig arch/s390/configs/defconfig arch/unicore32/configs/defconfig The path arch/*/configs/defconfig is already covered by "arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG)". So, this file path is not necessary. I moved the default KBUILD_DEFCONFIG to the top Makefile. Otherwise, the 7 architectures listed above would end up with endless loop of syncconfig.

2020-02-03kbuild: rename hostprogs-y/always to hostprogs/always-yMasahiro Yamada1-5/+5
In old days, the "host-progs" syntax was used for specifying host programs. It was renamed to the current "hostprogs-y" in 2004. It is typically useful in scripts/Makefile because it allows Kbuild to selectively compile host programs based on the kernel configuration. This commit renames like follows: always -> always-y hostprogs-y -> hostprogs So, scripts/Makefile will look like this: always-$(CONFIG_BUILD_BIN2C) += ... always-$(CONFIG_KALLSYMS) += ... ... hostprogs := $(always-y) $(always-m) I think this makes more sense because a host program is always a host program, irrespective of the kernel configuration. We want to specify which ones to compile by CONFIG options, so always-y will be handier. The "always", "hostprogs-y", "hostprogs-m" will be kept for backward compatibility for a while.

2020-01-06kconfig: Add yes2modconfig and mod2yesconfig targets.Tetsuo Handa1-1/+3
Since kernel configs provided by syzbot are close to "make allyesconfig", it takes long time to rebuild. This is especially waste of time when we need to rebuild for many times (e.g. doing manual printk() inspection, bisect operations). We can save time if we can exclude modules which are irrelevant to each problem. But "make localmodconfig" cannot exclude modules which are built into vmlinux because /sbin/lsmod output is used as the source of modules. Therefore, this patch adds "make yes2modconfig" which converts from =y to =m if possible. After confirming that the interested problem is still reproducible, we can try "make localmodconfig" (and/or manually tune based on "Modules linked in:" line) in order to exclude modules which are irrelevant to the interested problem. While we are at it, this patch also adds "make mod2yesconfig" which converts from =m to =y in case someone wants to convert from =m to =y after "make localmodconfig".

2019-11-11kconfig: Add option to get the full help text with listnewconfigLaura Abbott1-1/+4
make listnewconfig will list the individual options that need to be set. This is useful but there's no easy way to get the help text associated with the options at the same time. Introduce a new targe 'make helpnewconfig' which lists the full help text of all the new options as well. This makes it easier to automatically generate changes that are easy for humans to review.

2019-11-11kconfig: split util.c out of parser.yMasahiro Yamada1-1/+1
util.c exists both in scripts/kconfig/ and scripts/kconfig/lxdialog. Prior to commit 54b8ae66ae1a ("kbuild: change *FLAGS_<basetarget>.o to take the path relative to $(obj)"), Kbuild could not pass different flags to source files with the same basename. Now that this issue was solved, you can split util.c out of parser.y and compile them independently of each other. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-09-04kbuild: change *FLAGS_<basetarget>.o to take the path relative to $(obj)Masahiro Yamada1-4/+4
Kbuild provides per-file compiler flag addition/removal: CFLAGS_<basetarget>.o CFLAGS_REMOVE_<basetarget>.o AFLAGS_<basetarget>.o AFLAGS_REMOVE_<basetarget>.o CPPFLAGS_<basetarget>.lds HOSTCFLAGS_<basetarget>.o HOSTCXXFLAGS_<basetarget>.o The <basetarget> is the filename of the target with its directory and suffix stripped. This syntax comes into a trouble when two files with the same basename appear in one Makefile, for example: obj-y += foo.o obj-y += dir/foo.o CFLAGS_foo.o := <some-flags> Here, the <some-flags> applies to both foo.o and dir/foo.o The real world problem is: scripts/kconfig/util.c scripts/kconfig/lxdialog/util.c Both files are compiled into scripts/kconfig/mconf, but only the latter should be given with the ncurses flags. It is more sensible to use the relative path to the Makefile, like this: obj-y += foo.o CFLAGS_foo.o := <some-flags> obj-y += dir/foo.o CFLAGS_dir/foo.o := <other-flags> At first, I attempted to replace $(basetarget) with $*. The $* variable is replaced with the stem ('%') part in a pattern rule. This works with most of cases, but does not for explicit rules. For example, arch/ia64/lib/Makefile reuses rule_as_o_S in its own explicit rules, so $* will be empty, resulting in ignoring the per-file AFLAGS. I introduced a new variable, target-stem, which can be used also from explicit rules. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Marc Zyngier <maz@kernel.org>

2018-07-17kbuild: Rename HOST_LOADLIBES to KBUILD_HOSTLDLIBSLaura Abbott1-4/+4
In preparation for enabling command line LDLIBS, re-name HOST_LOADLIBES to KBUILD_HOSTLDLIBS as the internal use only flags. Also rename existing usage to HOSTLDLIBS for consistency. This should not have any visible effects. Signed-off-by: Laura Abbott <labbott@redhat.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2018-05-28kconfig: drop localization supportSam Ravnborg1-39/+3
The localization support is broken and appears unused. There is no google hits on the update-po-config target. And there is no recent (5 years) activity related to the localization. So lets just drop this as it is no longer used.
