The linux-next integration testing tree
21c54b7747
The kernel configuration phase is now tightly coupled with the compiler in use. 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> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
