CONFIG_IRQSOFF_TRACER: Interrupts-off Latency Tracer

General informations

The Linux kernel configuration item CONFIG_IRQSOFF_TRACER:

Help text

This option measures the time spent in irqs-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/tracing/tracing_max_latency

(Note that kernel size and overhead increase with this option enabled. This option and the preempt-off timing option can be used together or separately.)
