menu "Kernel hacking" source "lib/Kconfig.debug" config FRAME_POINTER bool default y config DEBUG_ERRORS bool "Verbose kernel error messages" depends on DEBUG_KERNEL help This option controls verbose debugging information which can be printed when the kernel detects an internal error. This debugging information is useful to kernel hackers when tracking down problems, but mostly meaningless to other people. It's safe to say Y unless you are concerned with the code size or don't want to see these messages. config DEBUG_STACK_USAGE bool "Enable stack utilization instrumentation" depends on DEBUG_KERNEL help Enables the display of the minimum amount of free stack which each task has ever had available in the sysrq-T output. config EARLY_PRINTK bool "Early printk support" default y help Say Y here if you want to have an early console using the earlyprintk=[,][,] kernel parameter. It is assumed that the early console device has been initialised by the boot loader prior to starting the Linux kernel. config PID_IN_CONTEXTIDR bool "Write the current PID to the CONTEXTIDR register" help Enabling this option causes the kernel to write the current PID to the CONTEXTIDR register, at the expense of some additional instructions during context switch. Say Y here only if you are planning to use hardware trace tools with this kernel. endmenu
