This debugging 15 information is useful to kernel hackers when tracking down problems, 16 but mostly meaningless to other people. It's safe to say Y unless 17 you are concerned with the code size or don't want to see these 18 messages. 19 20config DEBUG_STACK_USAGE 21 bool "Enable stack utilization instrumentation" 22 depends on DEBUG_KERNEL 23 help 24 Enables the display of the minimum amount of free stack which each 25 task has ever had available in the sysrq-T output. 26 27config EARLY_PRINTK 28 bool "Early printk support" 29 default y 30 help 31 Say Y here if you want to have an early console using the 32 earlyprintk=<name>[,<addr>][,<options>] kernel parameter. It 33 is assumed that the early console device has been initialised 34 by the boot loader prior to starting the Linux kernel. 35 36config PID_IN_CONTEXTIDR 37 bool "Write the current PID to the CONTEXTIDR register" 38 help 39 Enabling this option causes the kernel to write the current PID to 40 the CONTEXTIDR register, at the expense of some additional 41 instructions during context switch. Say Y here only if you are 42 planning to use hardware trace tools with this kernel. 43 44endmenu 45
