kbuild: support W=c and W=e shorthands for Kconfig KCONFIG_WARN_UNKNOWN_SYMBOLS=1 and KCONFIG_WERROR=1 are descriptive and suitable in scripting, but typing them from the command line can be tedious. Associate them with KBUILD_EXTRA_WARN (and the W= shorthand). Support a new letter 'c' to enable extra checks in Kconfig. You can still manage compiler warnings (W=1) and Kconfig warnings (W=c) independently. Reuse the letter 'e' to turn Kconfig warnings into errors. As usual, you can combine multiple letters in KCONFIG_EXTRA_WARN. $ KCONFIG_WARN_UNKNOWN_SYMBOLS=1 KCONFIG_WERROR=1 make defconfig can be shortened to: $ KBUILD_EXTRA_WARN=ce make defconfig or, even shorter: $ make W=ce defconfig Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nathan Chancellor <nathan@kernel.org>

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>

kconfig: do not use allnoconfig_y option 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.

kconfig: change defconfig_list option to environment variable "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>

kbuild: use KBUILD_DEFCONFIG as the fallback for DEFCONFIG_LIST 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.

kbuild: rename hostprogs-y/always to hostprogs/always-y 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.

kconfig: Add yes2modconfig and mod2yesconfig targets. 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".

kbuild: change *FLAGS_<basetarget>.o to take the path relative to $(obj) 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>

kconfig: do not require pkg-config on make {menu,n}config Meelis Roos reported a {menu,n}config regression: "I have libncurses devel package installed in the default system location (as do 99%+ on actual developers probably) and in this case, pkg-config is useless. pkg-config is needed only when libraries and headers are installed in non-default locations but it is bad to require installation of pkg-config on all the machines where make menuconfig would be possibly run." For {menu,n}config, do not use pkg-config if it is not installed. For {g,x}config, keep checking pkg-config since we really rely on it for finding the installation paths of the required packages.

kconfig: refactor ncurses package checks for building mconf and nconf The mconf (or its infrastructure, lxdiaglog) depends on the ncurses. Move and rename check-lxdialog.sh to mconf-cfg.sh to make it work in the same way as for qconf and gconf. This commit fixes some more weirdnesses. The nconf also needs ncurses packages. HOSTLOADLIBES_nconf is set to the libraries needed for nconf, but the cflags is not explicitly set. Actually, nconf relies on the check-lxdialog.sh for the proper cflags: HOST_EXTRACFLAGS += $(shell $(CONFIG_SHELL) $(check-lxdialog) -ccflags) \ -DLOCALE The code above passes the ncurses flags to all objects, even for conf, qconf, gconf. Let's pass the ncurses flags only to mconf and nconf. Currently, the presence of ncurses is not checked for nconf. Let's show a prompt like the mconf case. According to Randy's report, the shell scripts still need to carry the fallback code in case the pkg-config fails to find the ncurses packages.

kbuild: add %.lex.c and %.tab.[ch] to 'targets' automatically Files generated by if_changed* must be added to 'targets' to include *.cmd files. Otherwise, they would be regenerated every time. The build system automatically adds objects to 'targets' where appropriate, such as obj-y, extra-y, etc. but does nothing for intermediate files. So, each Makefile needs to add them by itself. There are some common cases where objects are generated by chained rules. Lexers and parsers are compiled like follows: %.lex.o <- %.lex.c <- %.l %.tab.o <- %.tab.c <- %.y They are common patterns, so it is reasonable to take care of them in the core Makefile instead of requiring each Makefile to do so. At this moment, you cannot delete 'target += zconf.lex.c' in the Kconfig Makefile because zconf.lex.c is included from zconf.tab.c instead of being compiled separately. It should be deleted after Kconfig is more refactored. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Frank Rowand <frowand.list@gmail.com>

kconfig: tests: add framework for Kconfig unit testing Many parts in Kconfig are so cryptic and need refactoring. However, its complexity prevents us from moving forward. There are several naive corner cases where it is difficult to notice breakage. If those are covered by unit tests, we will be able to touch the code with more confidence. Here is a simple test framework based on pytest. The conftest.py provides a fixture useful to run commands such as 'oldaskconfig' etc. and to compare the resulted .config, stdout, stderr with expectations. How to add test cases? ---------------------- For each test case, you should create a subdirectory under scripts/kconfig/tests/ (so test cases are separated from each other). Every test case directory should contain the following files: - __init__.py: describes test functions - Kconfig: the top level Kconfig file for the test To do a useful job, test cases generally need additional data like input .config and information about expected results. How to run tests? ----------------- You need python3 and pytest. Then, run "make testconfig". O= option is supported. If V=1 is given, detailed logs captured during tests are displayed.

'syncconfig' is the one I came up with because it updates the .config if necessary, then synchronize include/generated/autoconf.h and include/config/* with it.

kbuild: restore autoksyms.h touch to the top Makefile Commit d3fc425e819b ("kbuild: make sure autoksyms.h exists early") moved the code that touches autoksyms.h to scripts/kconfig/Makefile with obscure reason. From Nicolas' comment [1], he did not seem to be sure about the root cause. I guess I figured it out, so here is a fix-up I think is more correct. According to the error log in the original post [2], the build failed in scripts/mod/devicetable-offsets.c scripts/mod/Makefile is descended from scripts/Makefile, which is invoked from the top-level Makefile by the 'scripts' target. To build vmlinux and/or modules, Kbuild descend into $(vmlinux-dirs). This depends on 'prepare' and 'scripts' as follows: $(vmlinux-dirs): prepare scripts Because there is no dependency between 'prepare' and 'scripts', the parallel building can execute them simultaneously. 'prepare' depends on 'prepare1', which touched autoksyms.h, while 'scripts' descends into script/, then scripts/mod/, which needs <generated/autoksyms.h> if CONFIG_TRIM_UNUSED_KSYMS. It was the reason of the race. I am not happy to have unrelated code in the Kconfig Makefile, so getting it back to the top Makefile. I removed the standalone test target because I want to use it to create an empty autoksyms.h file. Here is a little improvement; unnecessary autoksyms.h is not created when CONFIG_TRIM_UNUSED_KSYMS is disabled.

License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

kconfig: Check for libncurses before menuconfig There is a check and a nice user-friendly message when the curses library is not present on the system and the user wants to do "make menuconfig". It doesn't get issued, though. Instead, we fail the build when mconf.c doesn't find the curses.h header: HOSTCC scripts/kconfig/mconf.o In file included from scripts/kconfig/mconf.c:23:0: scripts/kconfig/lxdialog/dialog.h:38:20: fatal error: curses.h: No such file or directory #include CURSES_LOC ^ compilation terminated. Make that check a prerequisite to mconf so that the user sees the error message instead: $ make menuconfig *** Unable to find the ncurses libraries or the *** required header files. *** 'make menuconfig' requires the ncurses libraries. *** *** Install ncurses (ncurses-devel) and try again. *** scripts/kconfig/Makefile:203: recipe for target 'scripts/kconfig/dochecklxdialog' failed make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1 Makefile:548: recipe for target 'menuconfig' failed make: *** [menuconfig] Error 2 Signed-off-by: Borislav Petkov <bp@suse.de> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Use pkg-config to find Qt 4 and 5 instead of direct qmake The Qt Project recommendation is that there should always be a "qmake" binary and it should never be renamed. If it's necessary to handle multiple Qt versions, the Qt Project recommends using qtchooser. Unfortunately, some distros do not follow the recommendation, so we would need to check qmake-qt4, qmake-qt5, etc. So, instead, let's try pkg-config.

scripts/kconfig/Makefile: Fix KBUILD_DEFCONFIG check when building with O= My recent commit d2036f30cfe1 ("scripts/kconfig/Makefile: Allow KBUILD_DEFCONFIG to be a target"), contained a bug in that when it checks if KBUILD_DEFCONFIG is a file it forgets to prepend $(srctree) to the path. This causes the build to fail when building out of tree (with O=), and when the value of KBUILD_DEFCONFIG is 'defconfig'. In that case we will fail to find the 'defconfig' file, because we look in the build directory not $(srctree), and so we will call Make again with 'defconfig' as the target. From there we loop infinitely calling 'make defconfig' again and again. The fix is simple, we need to look for the file under $(srctree).

scripts/kconfig/Makefile: Allow KBUILD_DEFCONFIG to be a target Arch Makefiles can set KBUILD_DEFCONFIG to tell kbuild the name of the defconfig that should be built by default. However currently there is an assumption that KBUILD_DEFCONFIG points to a file at arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG). We would like to use a target, using merge_config, as our defconfig, so adapt the logic in scripts/kconfig/Makefile to allow that. To minimise the chance of breaking anything, we first check if KBUILD_DEFCONFIG is a file, and if so we do the old logic. If it's not a file, then we call the top-level Makefile with KBUILD_DEFCONFIG as the target. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Acked-by: Michal Marek <mmarek@suse.com>

kconfig: add xenconfig defconfig helper This lets you build a kernel which can support xen dom0 or xen guests on i386, x86-64 and arm64 by just using: make xenconfig You can start from an allnoconfig and then switch to xenconfig. This also splits out the options which are available currently to be built with x86 and 'make ARCH=arm64' under a shared config. Technically xen supports a dom0 kernel and also a guest kernel configuration but upon review with the xen team since we don't have many dom0 options its best to just combine these two into one. A few generic notes: we enable both of these: CONFIG_INET=y CONFIG_BINFMT_ELF=y although technically not required given you likely will end up with a pretty useless system otherwise. A few architectural differences worth noting: $ make allnoconfig; make xenconfig > /dev/null ; \ grep XEN .config > 64-bit-config $ make ARCH=i386 allnoconfig; make ARCH=i386 xenconfig > /dev/null; \ grep XEN .config > 32-bit-config $ make ARCH=arm64 allnoconfig; make ARCH=arm64 xenconfig > /dev/null; \ grep XEN .config > arm64-config Since the options are already split up with a generic config and architecture specific configs you anything on the x86 configs are known to only work right now on x86. For instance arm64 doesn't support MEMORY_HOTPLUG yet as such although we try to enabe it generically arm64 doesn't have it yet, so we leave the xen specific kconfig option XEN_BALLOON_MEMORY_HOTPLUG on x86's config file to set expecations correctly. Then on x86 we have differences between i386 and x86-64. The difference between 64-bit-config and 32-bit-config is you don't get XEN_MCE_LOG as this is only supported on 64-bit. You also do not get on i386 XEN_BALLOON_MEMORY_HOTPLUG, there does not seem to be any technical reasons to not allow this but I gave up after a few attempts.

kbuild: add generic mergeconfig target, %.config "scripts/kconfig/merge_config.sh && make oldconfig" works well enough for merging local config fragments, but Kbuild currently has the entry points only for "kvmconfig" and "tinyconfig". This commit provides the generic target for mergeconfig, so we can manage our own config fragments easily: put "foo.config" in arch/$(SRCARCH)/configs/ or kernel/configs/, and then run "make foo.config". Now "make kvmconfig" is just a shorthand of "make kvm_guest.config". Likewise, "make tinyconfig" is equivalent to "make allnoconfig tiny.config".

kconfig: nconfig: fix multi-byte UTF handling Currently, Kconfig descriptions that use multi-byte UTF-8 characters (such as MTD_NAND_CAFE) will have their menu entries dropped from the 'make nconfig' ncurses menu, and all subsequent entries in the same window will be omitted. This seems to be due to the ncurses 'menu' library, which does not traditionally handle UTF-8 >8-bit characters properly. The ncursesw library ('w' is for "wide") is written to handle these UTF-8 characters, and is practically a drop-in replacement at the source level. Use it by default, if available.

x86: Add "make tinyconfig" to configure the tiniest possible kernel Since commit 5d2acfc7b974bbd3858b4dd3f2cdc6362dd8843a ("kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT") in 3.15-rc1, "make allnoconfig" disables every possible config option. However, a few configuration options (CC_OPTIMIZE_FOR_SIZE, OPTIMIZE_INLINING) produce a smaller kernel when turned on, and a few choices exist (compression, highmem, allocator) for which a non-default option produces a smaller kernel. Add a "tinyconfig" option, which starts from allnoconfig and then sets these options to configure the tiniest possible kernel. This provides a better baseline for embedded systems or efforts to reduce kernel size. Signed-off-by: Josh Triplett <josh@joshtriplett.org>

kconfig: Document oldnoconfig to what it really does The make target 'oldnoconfig' is a misnomer. It doesn't set new symbols to 'n', but instead sets it to their default values. Unfortunately, assuming that it actually did this, broke ktest in some of its tests. For example, the tests to create a minimum config and even a config bisect, depends on removing various configs and using oldnoconfig to get rid of other configs that may have depended on it. But because some configs that it was trying to disable, were in fact default enabled, this caused those configs to re-enable and corrupt the test. I thought about fixing oldnoconfig, but I'm afraid that people are already dependent on its current behavior. Instead, I'm just updating the documentation to state that it sets the new symbols to their default values and not to 'n'. Ideally, this would be called, 'olddefconfig' and we have an 'oldnoconfig' that actually disables the new symbols. But it's useless for me now. If it changed, ktest would need to be consistent between each version, and that would be to difficult to detect. I'll handle this issue with ktest with other means.

kconfig: add savedefconfig savedefconfig will save a minimal config to a file named "defconfig". The config symbols are saved in the same order as they appear in the menu structure so it should be possible to map them to the relevant menus if desired. The implementation was tested against several minimal configs for arm which was created using brute-force. There was one regression related to default numbers which had their valid range further limited by another symbol. Sample: config FOO int "foo" default 4 config BAR int "bar" range 0 FOO If FOO is set to 3 then BAR cannot take a value higher than 3. But the current implementation will set BAR equal to 4. This is seldomly used and the final configuration is OK, and the fix was non-trivial. So it was documented in the code and left as is.

If the file is an executable, it will execute it, otherwise it will read it as text. make LSMOD=/my/local/path/lsmod localmodconfig The above will execute the lsmod in /my/local/path instead of the lsmods that may be located elsewhere. make LSMOD=embedded_board_lsmod localmodconfig The above will read the "embedded_board_lsmod" as a text file. This is useful if you are doing a cross compile and need to run the config against modules that exist on an embedded device. Note, if the LSMOD= file does is not a path, it will add the path to the object directory. That is, the above example will look for "embedded_board_lsmod" in the directory that the binary will be built in (the O=dir directory).

kbuild: do not build mconf & lxdialog unless needed Due to a limitation in kbuild all objects referred by xxx-y or xxx-objs will be build when one of the targets needs to e build. This caused lxdialog to be build pulling in ncurses that is not always available. So avoid building mconf & lxdialog unless really needed. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

kconfig/menuconfig: lxdialog is now built-in lxdialog was previously called as an external program causing screen to flicker when used. With this patch lxdialog is now built-in. It is loosly based om previous work by: Petr Baudis <pasky@ucw.cz> Following is a list of changes: o Moved build of dialog routings to kconfig Makefile o menubox + checklist uses a new item list to hold all menu items o in util.c implmented helper function to deal with item list o menubox now uses parameters to save scroll state (avoids temp file) o textbox now get text to be displayed as parameter and not a file o make sure to properly delete subwin's before main windows o killed unused files: lxdialog.c msgbox.c o modified return value for ESC to match direct calling o in a few places the code has been adjusted to 80 char wide o in textbox a small refactoring was made to make code remotely readable o in mconf removed all unused stuff (functions/variables) Following is a list of know short comings: a) pressing ESC twice will be interpreted as two ESC presses b) resize does not work. menuconfig needs to be restarted to be adjusted Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

kbuild: change kbuild to not rely on incorrect GNU make behavior The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

kbuild: small update of allnoconfig description 'allnoconfig' is described by 'make help' as a "minimal config", that's not strictly correct. To be pedantic, a minimal config would be one where EMBEDDED was set to Y and most things therein disabled etc. Simply answering 'no' to all options does not give a minimal config. A better description of allnoconfig is that it answers all options with 'no'. This patch updates the description.

[PATCH] kconfig: detect if -lintl is needed when linking conf,mconf On a system where libintl.h is present, but the NLS functionality is supplied by a separate library instead of the system C library, an attempt to "make config" or "make menuconfig" will fail with link errors, ex: scripts/kconfig/mconf.o:mconf.c:(.text+0xf63): undefined reference to `_libintl_gettext' This patch attempts to correct the problem by detecting whether or not NLS support requires linking with libintl.

[PATCH] fix build on nls free systems I made a patch that detects if libintl.h (needed for nls) is present on the host system and if it's not, it nls support is disabled by providing dummies for the used nls functions. This way if there is nls support on the host system the *config targets will build according to Arnaldo Carvalho de Melo's i18n modifications, else it just uses the original English messages. I have also made a bug report at kernel's bugzilla: http://bugzilla.kernel.org/show_bug.cgi?id=5501 And there is a discussion about this problem in Gentoo's bugzilla: http://bugs.gentoo.org/show_bug.cgi?id=99810 Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

[PATCH] Kconfig i18n support This patch adds i18n support for make *config, allowing users to have the config process in their own language. No printk was harmed in the process, don't worry, so all the bug reports, kernel messages, etc, remain in english, just the user tools to configure the kernel are internationalized. Users not interested in translations can just unset the related LANG, LC_ALL, etc env variables and have the config process in plain english, something like: LANG= make menuconfig is enough for having the whole config process in english. Or just don't install any translation file. Translations for brazilian portuguese are being done by a team of volunteers at: http://www.visionflex.inf.br/kernel_ptbr/pmwiki.php/Principal/Traducoes To start the translation process: make update-po-config This will generate the pot template named scripts/kconfig/linux.pot, copy it to, say, ~/es.po, to start the translation for spanish. To test your translation, as root issue this command: msgfmt -o /usr/share/locale/es/LC_MESSAGES/linux.mo ~/es.po Replace "es" with your language code. Then execute, for instance: make menuconfig The current patch doesn't use any optimization to reduce the size of the generated .mo file, it is possible to use the config option as a key, but this doesn't prevent the current patch from being used or the translations done under the current scheme to be in any way lost if we chose to do any kind of keying. Thanks to Fabricio Vaccari for starting the pt_BR (brazilian portuguese) translation effort, Thiago Maciera for helping me with the gconf.cc (QT frontent) i18n coding and to all the volunteers that are already working on the first translation, to pt_BR. I left the question on whether to ship the translations with the stock kernel sources to be discussed here, please share your suggestions.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
