9 config DEBUG_STACK_USAGE
10 bool "Enable stack utilization instrumentation"
11 depends on DEBUG_KERNEL
13 Enables the display of the minimum amount of free stack which each
14 task has ever had available in the sysrq-T output.
17 bool "Early printk support"
20 Say Y here if you want to have an early console using the
21 earlyprintk=<name>[,<addr>][,<options>] kernel parameter. It
22 is assumed that the early console device has been initialised
23 by the boot loader prior to starting the Linux kernel.
25 config PID_IN_CONTEXTIDR
26 bool "Write the current PID to the CONTEXTIDR register"
28 Enabling this option causes the kernel to write the current PID to
29 the CONTEXTIDR register, at the expense of some additional
30 instructions during context switch. Say Y here only if you are
31 planning to use hardware trace tools with this kernel.
