Steven Rostedt が動作中のカーネルのlsmod情報から、必要なハードウェアのみONの最小 .configを生成してくれるスクリプトを開発した。
As it has been brought up last Kernel Summit, we want to make it easier
for those that report bugs to build their own kernels, and maybe even
bisect with git. Some of these people are not programmers and do not
understand the complexity of the configuration options. But to compile
a distribution configured kernel on their boxes can take hours.
This patch series comes to the rescue. I wrote the first instance of
streamline config when I bought a new box in 2005 and got frustrated
with finding all the necessary configurations to boot it. It is a
small (yet powerful) perl script.
Here's what it does:
* Reads the modules that are load by using lsmod.
* Reads all Makefiles to map modules to CONFIG_* options
* Reads the Kconfig files to find dependencies and selects
* Figures out what CONFIGS are needed to compile the loaded modules
* Reads the .config and prints out a version with all module configurations
that not needed, disabled.
The next two patches add options to make.
localmodconfig - this will run streamline_config.pl on the .config file
and replace it at the end.
localyesconfig - this will do the same as localmodconfig but will also
sed -i s/=m/=y/ to turn all modules to core. It will also run
the 'make oldcondfig' to fix it up and let the user handle
andything that was changed by converting a module to core.
Anyway, this is now in git and as a series of patches here. My git tree
is based off of the latest Linus git tree.
The following patches are in:
Steven Rostedt (3):
kconfig: add streamline_config.pl to scripts
kconfig: make localmodconfig to run streamline_config.pl
kconfig: add make localyesconfig option
