kconfig: make defconfig is no longer chatty

2008-07-25T20:12:51+00:00

make defconfig generated a lot of output then noone actually read. Use conf_set_all_new_symbols() to generate the default configuration and avoid the chatty output. A typical run now looks like this: $ make defconfig *** Default configuration is based on 'i386_defconfig' arch/x86/configs/i386_defconfig:13:warning: trying to assign nonexistent symbol SEMAPHORE_SLEEPERS arch/x86/configs/i386_defconfig:176:warning: trying to assign nonexistent symbol PREEMPT_BKL ... arch/x86/configs/i386_defconfig:1386:warning: trying to assign nonexistent symbol INSTRUMENTATION $ As an added benefit we now clearly see the warnings generated in the start of the process.

kconfig: make oldconfig is now less chatty

2008-07-25T20:12:50+00:00

Previously when running "make oldconfig" we saw all the propmt lines from kconfig and noone actully read this. With this patch the user will only see output if there is new symbols. This will be seen as "make oldconfig" runs which does not generate any output. A typical run now looks like this: $ make oldconfig scripts/kconfig/conf -o arch/x86/Kconfig $ If a new symbol is found then we restart the config process like this: $ make oldconfig scripts/kconfig/conf -o arch/x86/Kconfig * * Restart config... * * * General setup * Prompt for development and/or incomplete code/drivers (EXPERIMENTAL) [Y/n/?] y Local version - append to kernel release (LOCALVERSION) [] ... The bahaviour is similar to what we know when running the implicit oldconfig target "make silentoldconfig". "make silentoldconfig" are run as part of the kernel build process if the configuration has changed. Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: speed up all*config + randconfig

2008-07-25T20:12:49+00:00

Drop the chatty mode when we generate the all*config, randconfig configurations. Ths speeds up the process considerably and noone looked at the output anyway. This patch uses the conf_set_all_new_symbols() function just added to kconfig. Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: set all new symbols automatically

2008-07-25T20:12:48+00:00

Add conf_set_all_new_symbols() which set all symbols (which don't have a value yet) to a specifed value. Signed-off-by: Roman Zippel Signed-off-by: Sam Ravnborg

kconfig: add diffconfig utility

2008-07-25T20:12:41+00:00

Diffconfig is a simple utility for comparing two kernel configuration files. See usage in the script for more info. Signed-off-by: Tim Bird Signed-off-by: Sam Ravnborg

kernel-doc: handle/strip __init

2008-07-25T20:12:38+00:00

Handle __init in functions with kernel-doc notation by stripping the __init away from the output doc. This is already being done for "__devinit". This patch fixes these kernel-doc error/aborts: Error(linux-next-20080619//drivers/usb/gadget/config.c:132): cannot understand prototype: 'struct usb_descriptor_header **__init usb_copy_descriptors(struct usb_descriptor_header **src) ' Error(linux-next-20080619//drivers/usb/gadget/config.c:182): cannot understand prototype: 'struct usb_endpoint_descriptor *__init usb_find_endpoint( struct usb_descriptor_header **src, struct usb_descriptor_header **copy, struct usb_endpoint_descriptor *match ) ' Signed-off-by: Randy Dunlap Cc: David Brownell Signed-off-by: Sam Ravnborg

kbuild: prepare headers_* for arch/$ARCH/include

2008-07-25T20:12:33+00:00

Factor out the headers_*_all support to a seperate shell script and add support for arch specific header files can be located in either arch/$ARCH/include/asm or include/asm-$ARCH/ In "make help" always display the headers_* targets. Signed-off-by: Sam Ravnborg

kbuild: install all headers when arch is changed

2008-07-25T20:12:18+00:00

We see some header files that are selected dependent on the actual architecture so force a reinstallation of all header files when the arch changes. This slows down "make headers_check_all" but then we better reflect reality. Signed-off-by: Sam Ravnborg
