menu "Kernel hacking" source "lib/Kconfig.debug" config EARLY_PRINTK bool "Early printk" if EMBEDDED default y help Write kernel log output directly into the VGA buffer or to a serial port. This is useful for kernel debugging when your machine crashes very early before the console code is initialized. For normal operation it is not recommended because it looks ugly and doesn't cooperate with klogd/syslogd or the X server. You should normally N here, unless you want to debug such a crash. config 16KSTACKS bool "Use 16Kb for kernel stacks instead of 8Kb" help If you say Y here the kernel will use a 16Kb stacksize for the kernel stack attached to each process/thread. The default is 8K. This increases the resident kernel footprint and will cause less threads to run on the system and also increase the pressure on the VM subsystem for higher order allocations. endmenu
