Additional options used for $(LD) when linking modules.

KBUILD_KCONFIG

--------------------------------------------------

Set the top-level Kconfig file to the value of this environment

variable.  The default name is "Kconfig".

KBUILD_VERBOSE

--------------------------------------------------

Set the kbuild verbosity. Can be assigned same values as "V=...".

directory name found in the arch/ directory.

But some architectures such as x86 and sparc have aliases.

x86: i386 for 32 bit, x86_64 for 64 bit

sparc: sparc for 32 bit, sparc64 for 64 bit

sh: sh for 32 bit, sh64 for 64 bit

sparc: sparc32 for 32 bit, sparc64 for 64 bit

CROSS_COMPILE

--------------------------------------------------

the default option --strip-debug will be used.  Otherwise,

INSTALL_MOD_STRIP value will be used as the options to the strip command.

INSTALL_FW_PATH

--------------------------------------------------

INSTALL_FW_PATH specifies where to install the firmware blobs.

The default value is:

    $(INSTALL_MOD_PATH)/lib/firmware

The value can be overridden in which case the default value is ignored.

INSTALL_HDR_PATH

--------------------------------------------------

INSTALL_HDR_PATH specifies where to install user space headers when

Use "make help" to list all of the possible configuration targets.

The xconfig ('qconf') and menuconfig ('mconf') programs also

have embedded help text.  Be sure to check it for navigation,

search, and other general help text.

The xconfig ('qconf'), menuconfig ('mconf'), and nconfig ('nconf')

programs also have embedded help text.  Be sure to check that for

navigation, search, and other general help text.

General

for you, so you may find that you need to see what NEW kernel

symbols have been introduced.

To see a list of new config symbols when using "make oldconfig", use

To see a list of new config symbols, use

	cp user/some/old.config .config

	make listnewconfig

and the config program will list any new symbols, one per line.

Alternatively, you can use the brute force method:

	make oldconfig

	scripts/diffconfig .config.old .config | less

______________________________________________________________________

		This lists all config symbols that contain "hotplug",

		e.g., HOTPLUG_CPU, MEMORY_HOTPLUG.

	For search help, enter / followed TAB-TAB-TAB (to highlight

	For search help, enter / followed by TAB-TAB (to highlight

	<Help>) and Enter.  This will tell you that you can also use

	regular expressions (regexes) in the search string, so if you

	are not interested in MEMORY_HOTPLUG, you could try

	make MENUCONFIG_MODE=single_menu menuconfig

======================================================================

nconfig

--------------------------------------------------

nconfig is an alternate text-based configurator.  It lists function

keys across the bottom of the terminal (window) that execute commands.

You can also just use the corresponding numeric key to execute the

commands unless you are in a data entry window.  E.g., instead of F6

for Save, you can just press 6.

Use F1 for Global help or F3 for the Short help menu.

Searching in nconfig:

	You can search either in the menu entry "prompt" strings

	or in the configuration symbols.

	Use / to begin a search through the menu entries.  This does

	not support regular expressions.  Use <Down> or <Up> for

	Next hit and Previous hit, respectively.  Use <Esc> to

	terminate the search mode.

	F8 (SymSearch) searches the configuration symbols for the

	given string or regular expression (regex).

NCONFIG_MODE

--------------------------------------------------

This mode shows all sub-menus in one large tree.

Example:

	make NCONFIG_MODE=single_menu nconfig

======================================================================

xconfig

--------------------------------------------------

Searching in gconfig:

	None (gconfig isn't maintained as well as xconfig or menuconfig);

	however, gconfig does have a few more viewing choices than

	xconfig does.

	There is no search command in gconfig.  However, gconfig does

	have several different viewing choices, modes, and options.
