Component Type: kbuild config

Description: Preemption-off Latency Tracer

More info: This option measures the time spent in preemption-off critical sections, with microsecond accuracy. The default measurement method is a maximum search, which is disabled by default and can be runtime (re-)started via: echo 0 > /sys/kernel/debug/tracing/tracing_max_latency (Note that kernel size and overhead increase with this option enabled. This option and the irqs-off timing option can be used together or separately.)
