It will be nice to show the compiler information in Kconfig. The compiler information will be displayed like this: $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- config scripts/kconfig/conf --oldaskconfig Kconfig * * Linux/arm64 4.16.0-rc1 Kernel Configuration * * * Compiler: aarch64-linux-gnu-gcc (Linaro GCC 7.2-2017.11) 7.2.1 20171011 * * * General setup * Compile also drivers which will not load (COMPILE_TEST) [N/y/?] If you use GUI methods such as menuconfig, it will be displayed in the top menu. This is simply implemented by using the 'comment' statement. So, it will be saved into the .config file as well. This commit has a very important meaning. If the compiler is upgraded, Kconfig must be re-run since different compilers have different sets of supported options. All referenced environments are written to include/config/auto.conf.cmd so that any environment change triggers syncconfig, and prompt the user to input new values if needed. With this commit, something like follows will be added to include/config/auto.conf.cmd ifneq "$(CC_VERSION_TEXT)" "aarch64-linux-gnu-gcc (Linaro GCC 7.2-2017.11) 7.2.1 20171011" include/config/auto.conf: FORCE endif Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Kees Cook <keescook@chromium.org>

It is tedious to add a symbol entry for each environment variable given that we need to define much more such as 'CC', 'AS', 'srctree' etc. to evaluate the compiler capability in Kconfig. Adding '$' for symbol references is grammatically inconsistent. Looking at the code, the symbols prefixed with 'S' are expanded by: - conf_expand_value() This is used to expand 'arch/$ARCH/defconfig' and 'defconfig_list' - sym_expand_string_value() This is used to expand strings in 'source' and 'mainmenu' All of them are fixed values independent of user configuration. So, they can be changed into the direct expansion instead of symbols. This change makes the code much cleaner. The bounce symbols 'SRCARCH', 'ARCH', 'SUBARCH', 'KERNELVERSION' are gone. sym_init() hard-coding 'UNAME_RELEASE' is also gone. 'UNAME_RELEASE' should be replaced with an environment variable. ARCH_DEFCONFIG is a normal symbol, so it should be simply referenced without '$' prefix. The new syntax is addicted by Make. The variable reference needs parentheses, like $(FOO), but you can omit them for single-letter variables, like $F. Yet, in Makefiles, people tend to use the parenthetical form for consistency / clarification. At this moment, only the environment variable is supported, but I will extend the concept of 'variable' later on. The variables are expanded in the lexer so we can simplify the token handling on the parser side. For example, the following code works. [Example code] config MY_TOOLCHAIN_LIST string default "My tools: CC=$(CC), AS=$(AS), CPP=$(CPP)" [Result] $ make -s alldefconfig && tail -n 1 .config CONFIG_MY_TOOLCHAIN_LIST="My tools: CC=gcc, AS=as, CPP=gcc -E" Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Kees Cook <keescook@chromium.org>

CONFIG_CROSS_COMPILE allows users to change the compiler prefix from 'make menuconfig', etc. It means, the compiler options would have to be all re-calculated everytime CONFIG_CROSS_COMPILE is changed. To avoid complexity and performance issues, I'd like to evaluate the shell commands statically, i.e. only parsing Kconfig files. I guess the majority is [1] or [2].

However, this turned out not so clever as I had first expected. Actually, it is problematic. For example, "$(CC) -print-file-name" is cached. If the compiler is updated, the stale search path causes build error, which is difficult to figure out. Another problem scenario is cache files could be touched while install targets are running under the root permission. We can patch them if desired, but the build infrastructure is getting uglier and uglier. Now, we are going to move compiler flag tests to the configuration phase. If this is completed, the result of compiler tests will be naturally cached in the .config file. We will not have performance issues of incremental building since this testing only happens at Kconfig time. To start this work with a cleaner code base, remove the kbuild cache first.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, sparse assumes a 64bit machine when compiled on x86-64 and 32bit when compiled on anything else. This can of course create all sort of problems for the other archs, like issuing false warnings ('shift too big (32) for type unsigned long'), or worse, failing to emit legitimate warnings. Fix this by adding the -m32/-m64 flag, depending on CONFIG_64BIT, to CHECKFLAGS in the main Makefile (and so for all archs). Also, remove the now unneeded -m32/-m64 in arch specific Makefiles.

The problem is that ARM specific part of scripts/gcc-goto.sh fails with PIE even with recent gcc versions. Moving the asm goto detection up in Makefile put it before the place where we disable PIE. As a result, kernel is built without jump label support. Move the lines disabling PIE before the asm goto test to make it work.

* kbuild: use -fmacro-prefix-map to make __FILE__ a relative pathMasahiro Yamada2018-04-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | The __FILE__ macro is used everywhere in the kernel to locate the file printing the log message, such as WARN_ON(), etc. If the kernel is built out of tree, this can be a long absolute path, like this: WARNING: CPU: 1 PID: 1 at /path/to/build/directory/arch/arm64/kernel/foo.c:... This is because Kbuild runs in the objtree instead of the srctree, then __FILE__ is expanded to a file path prefixed with $(srctree)/. Commit 9da0763bdd82 ("kbuild: Use relative path when building in a subdir of the source tree") improved this to some extent; $(srctree) becomes ".." if the objtree is a child of the srctree. For other cases of out-of-tree build, __FILE__ is still the absolute path. It also means the kernel image depends on where it was built. A brand-new option from GCC, -fmacro-prefix-map, solves this problem. If your compiler supports it, __FILE__ is the relative path from the srctree regardless of O= option. This provides more readable log and more reproducible builds. Please note __FILE__ is always an absolute path for external modules. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

However, this does not address the case where both Python 2.x and 3.x scripts are used in one source tree. PEP 394 (https://www.python.org/dev/peps/pep-0394/) provides a convention for Python scripts portability. Here is a quotation: In order to tolerate differences across platforms, all new code that needs to invoke the Python interpreter should not specify 'python', but rather should specify either 'python2' or 'python3'. This distinction should be made in shebangs, when invoking from a shell script, when invoking via the system() call, or when invoking in any other context. One exception to this is scripts that are deliberately written to be source compatible with both Python 2.x and 3.x. Such scripts may continue to use python on their shebang line without affecting their portability. To meet this requirement, this commit adds new variables 'PYTHON2' and 'PYTHON3'. arch/ia64/scripts/unwcheck.py is the only script that has ever used $(PYTHON). Recent commit bd5edbe67794 ("ia64: convert unwcheck.py to python3") converted it to be compatible with both Python 2.x and 3.x, so this is the exceptional case where the use of 'python' is allowed. So, I did not touch arch/ia64/Makefile. tools/perf/Makefile.config sets PYTHON and PYTHON2 by itself, so it is not affected by this commit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As commit cedd55d49dee ("kconfig: Remove silentoldconfig from help and docs; fix kconfig/conf's help") mentioned, 'silentoldconfig' is a historical misnomer. That commit removed it from help and docs since it is an internal interface. If so, it should be allowed to rename it to something more intuitive. '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. You should not manually invoke 'silentoldcofig'. Display warning if used in case existing scripts are doing wrong.

[1] A user runs 'make' [2] First build with empty autoksyms.h [3] adjust_autoksyms.sh updates autoksyms.h and recurses 'make vmlinux' --------(begin sub-make)-------- [4] Second build with new autoksyms.h [5] link-vmlinux.sh is invoked because vmlinux is missing ---------(end sub-make)--------- [6] link-vmlinux.sh is invoked again despite vmlinux is up-to-date. The reason of [6] is probably because Make already decided to update vmlinux at the time of [2] because vmlinux was missing when Make built up the dependency graph. Because if_changed is implemented based on $?, this issue can be narrowed down to how Make handles $?. You can test it with the following simple code: [Test Makefile] A: B @echo newer prerequisite: $? cp B A B: C cp C B touch A [Result] $ rm -f A B $ touch C $ make cp C B touch A newer prerequisite: B cp B A Here, 'A' has been touched in the recipe of 'B'. So, the dependency 'A: B' has already been met before the recipe of 'A' is executed. However, Make does not notice the fact that the recipe of 'B' also updates 'A' as a side-effect. The situation is similar in this case; the vmlinux has actually been updated in the vmlinux_prereq target. Make cannot predict this, so judges the vmlinux is old. link-vmlinux.sh is costly, so it is better to not run it when unneeded. Split CONFIG_TRIM_UNUSED_KSYMS recursion to a dedicated target. The reason of commit 2441e78b1919 ("kbuild: better abstract vmlinux sequential prerequisites") was to cater to CONFIG_BUILD_DOCSRC, but it was later removed by commit 184892925118 ("samples: move blackfin gptimers-example from Documentation").

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.

I have been working with the (former) maintainers for each one to ensure that my interpretation was right and the code is definitely unused in mainline kernels. Many had fond memories of working on the respective ports to start with and getting them included in upstream, but also saw no point in keeping the port alive without any users. In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. In contrast, CPU instruction sets that remain popular and have actively maintained kernel ports tend to all be used across multiple licensees. [ See the new nds32 port merged in the previous commit for the next generation of "one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem" - Linus ] The removal came out of a discussion that is now documented at https://lwn.net/Articles/748074/. Unlike the original plans, I'm not marking any ports as deprecated but remove them all at once after I made sure that they are all unused. Some architectures (notably tile, mn10300, and blackfin) are still being shipped in products with old kernels, but those products will never be updated to newer kernel releases. After this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer. At least in case of hexagon, this will only be llvm, not gcc. - openrisc, risc-v and nds32 are still in the process of finishing their support or getting it added to mainline gcc in the first place. They all have patched gcc-7.3 ports that work to some degree, but complete upstream support won't happen before gcc-8.1. Csky posted their first kernel patch set last week, their situation will be similar [ Palmer Dabbelt points out that RISC-V support is in mainline gcc since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]" This really says it all: 2498 files changed, 95 insertions(+), 467668 deletions(-) * tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (74 commits) MAINTAINERS: UNICORE32: Change email account staging: iio: remove iio-trig-bfin-timer driver tty: hvc: remove tile driver tty: remove bfin_jtag_comm and hvc_bfin_jtag drivers serial: remove tile uart driver serial: remove m32r_sio driver serial: remove blackfin drivers serial: remove cris/etrax uart drivers usb: Remove Blackfin references in USB support usb: isp1362: remove blackfin arch glue usb: musb: remove blackfin port usb: host: remove tilegx platform glue pwm: remove pwm-bfin driver i2c: remove bfin-twi driver spi: remove blackfin related host drivers watchdog: remove bfin_wdt driver can: remove bfin_can driver mmc: remove bfin_sdh driver input: misc: remove blackfin rotary driver input: keyboard: remove bf54x driver ...

The product line is still around in the form of the BlueField SoC, but no longer uses the Tile architecture. There are also still products for sale with Tile-GX SoCs, notably the Mikrotik CCR router family. The products all use old (linux-3.3) kernels with lots of patches and won't be upgraded by their manufacturers. There have been efforts to port both OpenWRT and Debian to these, but both projects have stalled and are very unlikely to be continued in the future. Given that we are reasonably sure that nobody is still using the port with an upstream kernel any more, it seems better to remove it now while the port is in a good shape than to let it bitrot for a few years first.
