Once in it, hit / to get a search box. Enter GENERIC_CALIBRATE_DELAY (or a substring of that). Hit enter, and enjoy. :) Symbol: GENERIC_CALIBRATE_DELAY [=y] x x Type : boolean x x Defined at arch/x86/Kconfig:193 x x That's not very helpful. % find . -name 'Kconf*' | xargs grep GENERIC_CALIB ./lib/Kconfig.debug: depends on DEBUG_KERNEL && PRINTK && GENERIC_CALIBRATE_DELAY ./arch/metag/Kconfig:config GENERIC_CALIBRATE_DELAY ./arch/sh/Kconfig:config GENERIC_CALIBRATE_DELAY (and lots more). Turns out it's basically a flag for "This arch is able to support the BOOT_PRINTK_DELAY option"....
