--------------------------------------------------
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.

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.
