KCONFIG-MCONF(1)

💖 KCONFIG-MCONF(1) 💖

okay bestie, welcome to the kconfig-mconf manual page, October 2017 edition — yes she's a little vintage but she SERVES ✨

---

✨ NAME ✨

kconfig-monf — a standalone implementation of the Linux Kconfig parser 🫶

---

🎀 SYNOPSIS 🎀

kconfig-mconf [options] <KConfig_file>

---

🌸 DESCRIPTION 🌸

So the kconfig toolkit supports the Kconfig language and implements the parser plus the configuration support that goes with your KConfig files — and she respects the Linux kernel KConfig convention, no cap. 👑

At configuration time, here's the lineup:

• kconfig-mconf is based on ncurses (menuconfig) 💅
• kconfig-conf is based on dialog (config) 🦋
• kconfig-gconf is based on GTK+ (gconfig) 🌈

Associated tools:

• kconfig-diff displays symbols diff between .config files 🔥

---

💜 OPTIONS 💜

• --silentoldconfig — Only for kconfig-conf. Reloads a given .config and regenerates the header and command files accordingly. lowkey a glow-up for your config files ✨
• --allnoconfig — Set all boolean configuration to no. it's giving "no thank you" energy 💀
• --allyesconfig — Set all boolean configuration to yes. main character says YES to everything 👑
• --randconfig — Generates a random configuration. chaos config, we love her 🙈

---

🧚 ENVIRONMENT 🧚

Environment variables for '*config'

• KCONFIG_CONFIG — You can use this environment variable to specify a default kernel config file name, overriding the default name of ".config". so iconic of her 💅
• KCONFIG_OVERWRITECONFIG — If you set KCONFIG_OVERWRITECONFIG in the environment, Kconfig will not break symlinks when .config is a symlink to somewhere else. protect the symlink bestie 🫶
• CONFIG_ — If you set CONFIG_ in the environment, Kconfig will prefix all symbols with its value when saving the configuration, instead of using the default, "CONFIG_". custom prefix, custom vibe 🌸

Environment variables for '{allyes/allmod/allno/rand}config'

• KCONFIG_ALLCONFIG — The allyesconfig/allmodconfig/allnoconfig/randconfig variants can also use the environment variable KCONFIG_ALLCONFIG as a flag or a filename that contains config symbols that the user requires to be set to a specific value.

If KCONFIG_ALLCONFIG is used without a filename where KCONFIG_ALLCONFIG == "" or KCONFIG_ALLCONFIG == "1", "make *config" checks for a file named "all{yes/mod/no/def/random}.config" (corresponding to the *config command that was used) for symbol values that are to be forced. If this file is not found, it checks for a file named "all.config" to contain forced values. 🔍

This enables you to create "miniature" config (miniconfig) or custom config files containing just the config symbols that you are interested in. Then the kernel config system generates the full .config file, including symbols of your miniconfig file. literally a whole full-size config grown from a mini one 🌱

This 'KCONFIG_ALLCONFIG' file is a config file which contains (usually a subset of all) preset config symbols. These variable settings are still subject to normal dependency checks. ⚠️ so don't think you can just force whatever, the dependency checks said not today bestie

Examples:

KCONFIG_ALLCONFIG=custom-notebook.config make allnoconfig or
KCONFIG_ALLCONFIG=mini.config make allnoconfig or
make KCONFIG_ALLCONFIG=mini.config allnoconfig

These examples will disable most options (allnoconfig) but enable or disable the options that are explicitly listed in the specified mini-config files. 🎀

Environment variables for 'randconfig'

• KCONFIG_SEED — You can set this to the integer value used to seed the RNG, if you want to somehow debug the behaviour of the kconfig parser/frontends. If not set, the current time will be used. reproducible chaos, iconic ⭐
• KCONFIG_PROBABILITY — This variable can be used to skew the probabilities. See /usr/share/doc/kconfig-frontends/kconfig.txt.gz. 📖

Environment variables for 'silentoldconfig'

• KCONFIG_NOSILENTUPDATE — If this variable has a non-blank value, it prevents silent kernel config updates (requires explicit updates). she said no sneaky updates 🙅
• KCONFIG_AUTOCONFIG — This environment variable can be set to specify the path name of the "auto.conf" file. Its default value is "include/config/auto.conf". 🗂️
• KCONFIG_TRISTATE — This environment variable can be set to specify the path name of the "tristate.conf" file. Its default value is "include/config/tristate.conf". 🗂️
• KCONFIG_AUTOHEADER — This environment variable can be set to specify the path name of the "autoconf.h" (header) file. Its default value is "include/generated/autoconf.h". 🗂️
