* kconfig: Fix make O=<dir> local{mod,yes}configSteven Rostedt2009-11-201-6/+6
| | | | | | | | | | When the output directory is something other than the kernel source, the streamline_config script gets confused. This patch passes in the source directory to the script so that it can find the proper files.

* kconfig: make local .config default for streamline_configSteven Rostedt2009-08-181-4/+4
| | | | | | | | | | As Andi Kleen pointed out, most people would expect that the local .config file to be based for a streamline config. This patch changes the order of searching for a config file to consider the .config in the local directory first.

* kconfig: test for /boot/config-uname after /proc/config.gz in localconfigSteven Rostedt2009-08-181-0/+4
| | | | | | | | Many distros put their config in /boot/config-`uname -r`, add a check for that right after /proc/config.gz Reported-by: Alan Jenkins <sourcejedi.lkml@googlemail.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* kconfig: unset IKCONFIG_PROC and clean up nestingSteven Rostedt2009-08-181-6/+3
| | | | | | | | | | Due to cut and paste error IKCONFIG was both set and cleared. It was suppose to be IKCONFIG_PROC to be cleared. Also cleaned up if nesting. Reported-by: Alan Jenkins <sourcejedi.lkml@googlemail.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* kconfig: search for a config to base the local(mod|yes)config onSteven Rostedt2009-08-181-1/+62
| | | | | | | | | | | | | | | | | | | | | Instead of using the .config in the local directory. This patch changes streamline_config.pl to search various locations for a config. Here's the list and order of search: /proc/config.gz /boot/vmlinuz-`uname -r` vmlinux # local to the directory /lib/modules/`uname -r`/kernel/kernel/configs.ko kernel/configs.ko kernel/configs.o .config Once it finds a file that contains a config (it checks if the binary objects have configs first) it then uses it to create the .config with minimum modules needed.

* kconfig: enable CONFIG_IKCONFIG from streamline_config.plSteven Rostedt2009-08-181-10/+23
| | | | | | | | | | | | | | | Ingo Molnar suggested that the streamline_config.pl should enable CONFIG_IKCONFIG to keep the current config in the kernel. Then we can use scripts/extract-ikconfig to find the current modules. This patch changes streamline_config.pl to check if CONFIG_IKCONFIG is not set, and if it is not, it enables it to be a module. [ Impact: make current config options easier to find ] Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* kconfig: do not warn about modules built inSteven Rostedt2009-08-181-3/+5
| | | | | | | | | | | | | | The streamline_config.pl finds all the configs that are needed to compile the currently loaded modules. After it creates the .config file, it tests to make sure all the configs that are needed were set. It only looks at the configs that are modules, it does not look at the builtin configs. This causes unnecessary warnings about modules not being covered. Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* kconfig: streamline_config.pl do not stop with no dependsSteven Rostedt2009-08-181-5/+3
| | | | | | | | | | | | | | | | | If a config does not have a prompt, it must be selected. streamline_config.pl keeps track of all configs that select other configs. If a config that does not have a prompt needs to be set to enable a current module, it will include all configs that select it. Note, streamline_config.pl does not enable modules that are not already enabled. It only keeps enabled those that were enabled and might be needed to compile the current modules. The code to find the selects of a config is after the code that adds the depends. But if a config needed selects but had no dependencies, it would not be set. Because the code would stop before getting to the select. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* kconfig: add streamline_config.pl to scriptsSteven Rostedt2009-08-181-0/+291
streamline_config.pl is a very powerful tool. For those that install a kernel to a new box using the config file from the distribution know that it can take forever to compile the kernel. Making a custom config file that will still boot your box, but bring down the compile time of the kernel can be quit painful, and to ask someone that reported a bug to do this can be a large burdon since that person may not even know how to build a kernel. This script will perform "lsmod" to find all the modules loaded on the current running system. It will read all the Makefiles to map which CONFIG enables a module. It will read the Kconfig files to find the dependencies and selects that may be needed to support a CONFIG. Finally, it reads the .config file and removes any module "=m" that is not needed to enable the currently loaded modules. The output goes to standard out. Here's a way to run the script. From the Linux directory that holds a distribution .config. $ scripts/kconfig/streamline_config.pl arch/x86/Kconfig > config-sl $ mv .config config-save $ mv config-sl .config $ make oldconfig Now you have a .config that will still build all your modules, but also take much less time to build the kernel.
