fixdep: fix extraneous dependencies

2011-09-09T09:45:47Z

The introduction of include/linux/kconfig.h created 3 extraneous dependencies: include/config/.h include/config/h.h include/config/foo.h Fix this by excluding kconfig.h from fixdep calculations. Signed-off-by: Peter Foley Signed-off-by: Michal Marek

kbuild: move scripts/basic/docproc.c to scripts/docproc.c

2011-05-02T20:48:03Z

Move docproc from scripts/basic to scripts so it is only built for *doc targets instead of every time the kernel is built.

kbuild: Fix computing srcversion for modules

2011-03-13T22:59:58Z

Recent change to fixdep: commit b7bd182176960fdd139486cadb9962b39f8a2b50 Author: Michal Marek Date: Thu Feb 17 15:13:54 2011 +0100 fixdep: Do not record dependency on the source file itself changed the format of the *.cmd files without realizing that it is also used by modpost. Put the path to the source file to the file back, in a special variable, so that modpost sees all source files when calculating srcversion for modules.

fixdep: Do not record dependency on the source file itself

2011-02-21T12:35:17Z

The dependency is already expressed by the Makefiles, storing it in the .cmd file breaks build if a .c file is replaced by .S or vice versa, because the .cmd file contains foo/bar.o: foo/bar.c ... foo/bar.c ... : so the foo/bar.c -> foo/bar.o rule triggers even if there is no foo/bar.c anymore.

fixdep: use hash table instead of a single array

2010-11-11T16:12:06Z

I noticed fixdep uses ~2% of cpu time in kernel build, in function use_config() fixdep spends a lot of cpu cycles in linear searches in its internal string array. With about 400 stored strings per dep file, this begins to be noticeable. Convert fixdep to use a hash table. kbuild results on my x86_64 allmodconfig Before patch : real 10m30.414s user 61m51.456s sys 8m28.200s real 10m12.334s user 61m50.236s sys 8m30.448s real 10m42.947s user 61m50.028s sys 8m32.380s After: real 10m8.180s user 61m22.506s sys 8m32.384s real 10m35.039s user 61m21.654s sys 8m32.212s real 10m14.487s user 61m23.498s sys 8m32.312s Signed-off-by: Eric Dumazet Signed-off-by: Michal Marek
