| 1 2config PRINTK_TIME 3 bool "Show timing information on printks" 4 help 5 Selecting this option causes timing information to be 6 included in printk output. This allows you to measure 7 the interval between kernel operations, including bootup 8 operations. This is useful for identifying long delays --- 81 unchanged lines hidden (view full) --- 90 depends on DEBUG_KERNEL && PREEMPT 91 default y 92 help 93 If you say Y here then the kernel will use a debug variant of the 94 commonly used smp_processor_id() function and will print warnings 95 if kernel code uses it in a preemption-unsafe way. Also, the kernel 96 will detect preemption count underflows. 97 | 1 2config PRINTK_TIME 3 bool "Show timing information on printks" 4 help 5 Selecting this option causes timing information to be 6 included in printk output.
